FAA Approves Type Certification for S-76D Helicopter
STRATFORD, Connecticut | The Federal Aviation Administration (FAA) has approved the Type Certificate for the S-76D helicopter, moving the aircraft forward to its highly anticipated delivery into the medium-sized marketplace. Sikorsky Aircraft Corp. is a subsidiary of United Technologies Corp.
The FAA signed the certificate on Oct. 12, capping an intensive flight test program to introduce the S-76D helicopter, Sikorsky’s newest commercial product. The S-76D helicopter has a current backlog approaching a half-billion dollars and is expected to begin deliveries later this quarter.
“Our customers are excited to begin receiving the S-76D into their fleets. We are equally excited to deliver a new product that represents three and a half decades of continuous product improvement, to offer them a helicopter with improved efficiency, power and best-in-class noise signature,” said Carey Bond, President of Sikorsky Global Helicopters.
Ed Beyer, Vice President of Sikorsky Global Helicopters, added: “The S-76D helicopter ushers in a new era of excellence across mission segments. The S-76D will be incorporated into the fleets of our customers for every mission segment it currently performs including offshore support, VIP, Search and Rescue, and EMS. The S-76D helicopter will offer a higher cruise speed than its predecessors, coupled with more efficient fuel burn, making the S-76 more productive than ever.”
The S-76D helicopter is the latest in the family of popular S-76 helicopters manufactured by Sikorsky. There have been more than 800 S-76 helicopters delivered to the global fleet since 1979, contributing daily to a growing 6 million-plus flight hours.
Designed for safety, reliability and efficiency, the S-76D helicopter’s standard equipment features are all-composite, flaw-tolerant main rotor blades; an advanced THALES integrated avionics system and autopilot; health and usage monitoring system, active vibration control; and powerful Pratt & Whitney Canada PW210S engines. Rotor Ice Protection System for all-weather capability will be available as an option.

Sikorsky starts construction of S-97 Raider prototypes
Sikorsky has started building two prototype S-97 Raider high-speed compound helicopters for the US Army's prospective Armed Aerial Scout programme.
The coaxial-rotor, pusher-prop machine is based on the company's revolutionary X-2 design which won the Collier Trophy in 2010. The S-97 is currently in its detailed design phase, but because Sikorsky is developing the aircraft as a prototype, the company has already started fabricating the new rotor-craft.
"We're in detailed design right now," says Doug Shidler, Sikorsky's S-97 programme manager. "And because we're a rapid prototype programme, as we're going through detailed design, we're also building parts."
Parts of the aircraft's fuselage are already being built as are other components throughout the airframe. In fact, some components have already been completed, Shidler says. The objective for the year is to complete the design.
The aircraft should move into final assembly by the middle of next year, Shidler says. The aircraft should enter ground and flight testing in 2014. "Things are moving along as projected," he adds.
Sikorsky
Unlike a conventional helicopter, which typically is limited to about 180 knots, the S-97 will be able to cruise at speeds of 220 knots with external weapon and 235 knots clean. It will also be able reach a dash speeds of 245 knots to 250 knots.
The company is committed to building the S-97 regardless of what happens to the AAS programme. The army will make a decision on if it will go ahead with buying a new helicopter to replace the Bell OH-58 Kiowa Warrior or soldier on with the decades-old machine in December. Shidler notes that both the X-2 and the S-97 are entirely funded by industry dollars. The S-97 project is 75% funded by Sikorsky and 25% funded by suppliers-which includes labor and materials.
The X-2 technology is also applicable to the army's Joint-Multi Role (JMR)/Future Vertical Lift (FVL) efforts. The technology can be scaled-up for a medium weight helicopter and to far larger aircraft. Sikorsky has explored concepts that rival the Lockheed Martin C-130 in size-but which has two pusher propellers rather than just one. "You can scale it to whatever you need for a helicopter/rotorcraft mission," says Steven Engebretson, Sikorsky's Armed Aerial Scout programme director.
The service is expected to release a broad area announcement that will examine potential technologies for the future JMR/FVL programme.
"Sikorsky intends to be a competitor in that arena," Engebretson says. The S-97, Engebretson says, is a "great demonstration" of next-generation capability-he notes the X-2 technology will play be key role in Sikorsky's plans going forward.
There are civilian applications for the X-2 technology, Shidler notes, but those are "further off." It could be used for search and rescue or ferrying worker to off-shore oil rigs, for example.

Test team completes final mission on retiring CH-46E helicopter
A CH-46E Sea Knight helicopter prepares to lift a “Bambi” bucket full of water during envelope expansion testing of the aerial firefighting apparatus. The test team for the CH-46E Sea Knight helicopter recently completed its final mission on the aircraft, which is slated for retirement in 2016. (U.S. Navy photos)
From left, Marine Corps Lt. Col. John Neville, Air Test and Evaluation Squadron Two One (HX 21) chief test pilot, and Don Mueller, HX-21 test pilot, s ...
NAVAL AIR SYSTEMS COMMAND, PATUXENT RIVER, Md. – After more than 750 hours and 500 flights, the test team for the CH-46E Sea Knight helicopter recently completed its final mission as the helicopter, affectionately known as the Phrog, prepares for retirement in 2016.
The test team, based here at Naval Air Station Patuxent River, completed the final flight Oct. 9.
Part of Air Test and Evaluation Squadron (HX) 21, the “Mighty Battle Phrog” Test Team was established in 2008 to improve survivability and viability of the CH-46E. HX-21 covers the entire spectrum of ordnance-related operations, including weapons safe jettison separation, delivery and accuracy, night thermal imaging systems, helmet mounted night vision and head-up display systems, target sighting systems development, and stores jettison validation.
“The Phrog is the workhorse of the Marines and every pilot that has ever flown one has a special affection for the aircraft,” said Don Mueller, test team project officer. “To be able to extend the life of this aircraft, so that it could keep the Marines flying meant a lot to us. We all loved flying and working on this aircraft. We are going to miss it.”
Employed in every conflict since Vietnam, the CH-46E is a medium-lift, tandem-rotor cargo helicopter used by the Marine Corps to provide all-weather, day-or-night assault transport of combat troops, supplies and equipment.
The helicopter has seen several rebirths. Flight testing of the Sea Knight was thought to be complete in 1996, however, in February 2007 “urgent needs” from the fleet and changes to the MV-22B Osprey delivery schedule – the CH-46E’s replacement – pushed modifications and upgrades to the existing helicopters, delaying its retirement by a decade. Though targeted again for retirement in 2016, at least 16 Phrogs are being acquired by the U.S. State Department for diplomatic missions.
"The Phrog test team at HX-21 was an indispensable contributor to the enduring warfighting capability of the H-46,” said Marine Corps Lt. Col. David Walsh, the program manager for the Specialized and Proven Aircraft Program Office, which supports the CH-46E. “The team’s professionalism and fleet-focused approach benefited not just the H-46 community, but Marine aviation as a whole."
Flight testing to improve survivability and to increase payload capability of the aircraft began in earnest in 2008, with initial efforts primarily benefitting the H-46 community. However, the team’s success and ability to quickly deliver results garnered the attention of other organizations, which leveraged its expertise.
The team supported test verifications for the MH-53 helicopter, provided operational test support to Naval Sea Systems Command for its new ship-borne chemical and biological sensor system and participated in two Marine Aviation and Tactics Squadron exercises. The group was also tapped to provide supplementary fleet squadron training and to improve the H-46 trainer.
Other projects completed by the team included evaluation of three separate missile countermeasures systems, aircraft health monitoring, high-frequency radio upgrades and wireless and replacement intercommunication systems. The wide range of tests benefited not only the CH-46E community, but the H-53, V-22, H-60 and H-47 communities as well, Mueller said.
“Of all of the aircraft in today's Navy/Marine [Corps] fleet, the Phrog has the lowest maintenance man hour and cost-per-flight hour,” Mueller said. “To be able to meet the many emergent requirements the flight test team was faced with, we had to quickly plan, test and get the results back to the fleet. We were able to accomplish this because our test team consisted of a small group of maintainers and engineers who were dedicated to the aircraft.”

Boeing marks the 50th anniversary of the Chinook
Friday 17th August 2012 at 16:08
Netherlands Air Force Boeing CH-47D Chinook Boeing marks the 50th anniversary of delivering the first H-47 Chinook military helicopter and is nearing completion of a $130 million renovation of its production line near Philadelphia that will help it meet global demand for the latest model, the CH-47F.
Boeing Chinook Helicopter
"The Chinook has served as the backbone of U.S. Army aviation since the Vietnam era, revolutionizing how we move troops and supplies in combat, and save lives and deliver aid in times of need," said Col. Bob Marion, U.S. Army Cargo Helicopter program manager. "The latest F-model has ushered in a new era of heavy-lift capability for the U.S. Army. With continued technology insertions, I fully expect that 50 years from now there will be a centennial celebration for Chinooks still in service." Six RAF Boeing Chinook HC2 helicopters at Athens
The Chinook is a multi-mission, heavy-lift transport helicopter. Its primary mission is to move troops, artillery, ammunition, fuel, water, barrier materials, supplies and equipment on the battlefield. Its secondary missions include medical evacuation, disaster relief, search and rescue, aircraft recovery, fire fighting, parachute drops, heavy construction and civil development.
Boeing has delivered more than 1,200 Chinooks to 18 operators around the world since delivering the first to the U.S. Army on Aug. 16, 1962. More than 800 are in operation today, conducting combat, cargo transport and humanitarian relief missions.
"Chinook is Boeing’s longest continuously running production program, and it’s in greater demand today than ever before," said Leanne Caret, vice president, Vertical Lift and H-47 Programs. "Chinooks are being delivered on schedule and operating at a higher rate than any time in history, thanks to our team's innovation, efficiency, and focus on meeting our customers' needs."
The production line updates will enable Boeing to continue to affordably increase Chinook production rates. Boeing is scheduled to deliver nearly 60 Chinooks this year and has submitted a multiyear, firm fixed-price proposal to the Department of Defense to provide 155 CH-47Fs to the U.S. Army with deliveries beginning in 2015.

New Middle East Clients Lining Up To Buy CH-47 Chinooks Aug. 29, 2013 - 03:51PM | By PAUL McLEARY
MIDDLETOWN, DEL. — Libya, Saudi Arabia, and Qatar head the list of countries looking to begin flying variants of the CH-47 Chinook helicopter in coming years, Boeing officials said here Wednesday. .
If deals being negotiated between Boeing, the US government, and these three countries eventually come to fruition, projections are that at least 54 Chinooks would be shipped overseas, making up a good portion of the 168 Chinooks that foreign clients around the globe are considering buying in coming years.
Pentagon officials and defense industry brahmins have been talking for the better part of two years about how they’re planning to rely on foreign sales to make up for the reductions they’re seeing in the US defense market, but a chart shown to reporters Wednesday really drove that point home.
On top of the 830 Chinook H-47 variants that are currently flying around the world, the chart showed, Boeing executives are working with foreign clients and the US government to sell another 168 to new and existing clients if all goes as planned.
In addition to the six CH-47D models and 16 CH-47F models that Libyan officials are working on buying, Saudi Arabia has expressed interest in fielding one of the world’s largest CH-47F fleets, with at least 24 helicopters being considered for the oil-rich kingdom.
Mark Ballew, director of business development for Boeing’s Chinook program, said the company is preparing to do a flight demonstration in Saudi Arabia, and that Qatar is interested in buying eight of the “F” models similar to what the company produced for Canada, which feature larger external fuel tanks and an upgraded electrical system. Morocco, which has already purchased three “D” models, also is talking about buying three more, and Egypt, which currently flies 18 “D”s, has enquired about buying six more from the US Army as it retires them in the switch to the upgraded “F” aircraft.
Boeing is also involved in the competition for India’s heavy lift requirement, which would mean 15 more “F” aircraft if it wins.
The deals with these countries are still very early on in the negotiation stage, Ballew and other executives stressed, adding that contracts for the birds aren’t expected soon.
Any deals several years down the road would be welcome news for Boeing, however, as the company’s $4 billion, five-year deal with the US Army for 214 more CH-47 “F” models will end in 2019.
That agreement would add to the 241 CH-47F helicopters that the Army already has in its fleet, eventually bringing the service close to its goal of 464 “F” models.
The foreign deals — especially with countries in the Middle East — aren’t just helicopter contracts, however. Countries in the region have generally neglected establishing their own maintenance and logistics programs, which would mean years of repair work for the contractor.

Rolls-Royce Boosts Power for V-22 Engines
WASHINGTON — Engine manufacturer Rolls-Royce has increased the power output of its V-22 Osprey engine by 17 percent, a significant jump that should boost the reliability of the tilt-rotor aircraft in high-altitude, high-heat conditions, according to a company official.
“We’ve been upgrading the [AE family] of engines to provide more thrust as more challenging requirements came up in the commercial market, so we knew there was more power available” said Tom Hartmann, the company’s senior vice president of defense. “Now that we’re through the hurdles of wrestling and working the time-on-wing improvements, we recognize there is additional capability we haven’t taken advantage of that could provide high power to the Pentagon for their particular missions.”
The engine improvements came from three relatively small changes. First, the company added a new turbine to the engine, known as the Block 3 turbine. That design is based on a commercial product Rolls-Royce has used.
Some of those turbines are already in the field; the company has been installing them into all new-production models since July 2012, and began upgrading older turbines during regular maintenance two months later.
The other modifications included an increase in the flow capacity of the fuel valve and a software update, which allow the engines to deliver the higher power when needed.
Each V-22 Osprey is powered by a pair of Rolls-Royce AE 1107C engines. The US Air Force’s fleet of CV-22s are used for special operations missions. The US Marine Corps’ MV-22 has two variants, the B and C models, which are used in the transportation of troops and equipment.
Most of the time, the V-22 won’t need the extra power. It’s really designed for use at higher altitudes — the 6,000-8,000-foot range — where the V-22 has struggled.
“Without flight tests, it’s hard to say the real-world impact” of the improvements, Hartmann said. But Rolls aims to give US military operators full engine capability at 6,000 feet with an air temperature of 95 degrees, a challenge that he said Air Force officials asked the company to look at.
“Right now, they are limited on what load they can carry at 6,000 feet and 95 degrees.” Hartmann said. “The plan is to provide that full capability in the near term, and then, in a future upgrade, give enhanced capability at 8,000 feet and 95 degrees.”
The company will begin tests of its upgraded engine in the fall, beginning the Federal Aviation Administration review process. Hartmann expects kits for the improved engines to arrive late 2014.
Rolls also is keeping an eye on a more comprehensive Block 4 upgrade, which should increase power by 26 percent over the current baseline, allowing the engines to hit close to 10,000 horsepower. It also could improve fuel consumption, which the company expects to be key as the Pentagon focuses more on the Asia-Pacific region.
“You have the ‘tyranny of distance’ in the Pacific, so better fuel consumption is obviously a benefit in that region,” Hartmann said.

Black Hawks new milestone in modernisation of defence forces
THE Sikorsky S-70i Black Hawk helicopters were unveiled at the fourth Brunei Darussalam International Defence Exhibition and Conference (BRIDEX) yesterday, marking another milestone in the modernisation of the Royal Brunei Armed Forces (RBAF).
His Majesty the Sultan and Yang Di-Pertuan of Brunei Darussalam, Minister of Defence and Supreme Commander of RBAF, witnessed the unveiling of the new aircraft while touring the Sikorsky Aircraft Corporation’s pavilion at the Exhibition Hall 2.
Samir B Mehta, president of Sikorsky Military Systems, told The Brunei Times that the first batch of S-70i Black Hawk helicopters were delivered ahead of schedule, owing to their collaborative working relationship with the Ministry of Defence (MinDef).
“Whenever you have a company like ours and a great customer like MinDef working together, you can do things like accelerate schedule. You can still make sure, however, that you have the highest quality helicopter,” he said.
Uniquely configured for Brunei, the new S-70i model represent the most advanced upgrades that have been made to the aircraft over its history to include state-of-the-art avionics with dual-digit flight control computers among others.
With unmatched manoeuvrability, the Black Hawk is recognised worldwide as the premier utility helicopter for troop transport, cargo, medical evacuation as well as search and rescue operations, according to a press statement.
Four out of 12 helicopters have been delivered and the fifth is expected to be shipped sometime this month, while the remaining aircraft will be transported over the following year. Royal Brunei Air Force (RBAirF) pilots have also been trained to fly the S-70i at the West Palm Beach facility.
“The delivery of the helicopters is not the end of the relationship, but the beginning… It’s also about making sure these helicopters have a high rate of mission availability for the next 20 to 30 years,” said Mehta.
He added that Sikorsky has a significant amount of spare parts available to support the S-70i helicopters as it goes into operational service. They will also provide on-site technical service and logistic representatives to ensure the supply of parts and services remain uninterrupted.
Brigadier General (U) Hj Wardi Hj Abd Latip, RBAirF commander, said the new fleet of aircraft will be fully operational latest by early 2015. The S-70i will replace the current fleet of Bell 212s that have been operation for over 30 years.
Equipped with long-range tanks, the new Black Hawks will facilitate deployment around the region. Although the RBAirF’s four S-70A helicopters share similar capabilities, Brigadier General (U) Hj Wardi explained the previous version will be obsolete with the introduction of the S-70i.
“They will become obsolete soon with these new ones supplementing our operations and deployment in Mindanao. They can carry more fuel, more load. It’s a state-of-the-art aircraft,” he said, noting the S-70i aircraft were battle-proven.
Asked if the new helicopters will feature a black box, the RBAirF Commander indicated they will “eventually get some kind of flight data recorder”.
He commented that a black box “is good to have in military operations”.
Meanwhile, Daniel L Shields, United States Ambassador to Brunei, also weighed in on the procurement of the Black Hawk helicopter, pointing out that it will help strengthen defence relations between the two countries.
“I’m grateful to His Majesty and the Government of Brunei for choosing these wonderful American helicopters. I really hope it can contribute to meeting their national defence objectives as well as humanitarian assistance and disaster relief operations,” he said.
Sikorsky and MinDef in 2011 signed a contract for the supply of 12 S-70i Black Hawk helicopters with associated spare parts, training and ground support equipment.
The S-70i is the international variant of the UH-60M helicopter used by the United States Army.

Russia to Modify Mi-8 Helicopter for Arctic Warfare
ULAN-UDE, December 25 (RIA Novosti) – Russia’s Ulan-Ude aircraft manufacturing plant said Wednesday that it is developing a variant of the famed Mi-8 transport helicopter for use by the military in harsh Arctic climate.
The modified Mi-8 will feature a more powerful engine, an auxiliary electric generator, an ice-protection system and ski landing gear for landing on soft snow and swamps.
“The helicopter’s heating system will be based on technologies used on spacecraft,” said Sergei Solomin, the plant’s chief engineer.
Russia has officially set a goal of deploying a combined arms force by 2020 to protect its political and economic interests in the Arctic, including military, border and coastguard units.
According to the Russian military, two Arctic brigades will be deployed in Russia’s extreme north over the next few years. Russia also plans to return to mothballed Soviet-era Arctic airfields and establish a permanent naval presence along the strategically important Northern Sea Route.
The Arctic, believed to have vast untapped natural resources, has increasingly been at the center of disputes between the United States, Russia, Canada, Norway and Denmark in recent years, as rising temperatures lead to a reduction in sea ice, opening up access to lucrative offshore oil and gas deposits.

APU testing begins on Sikorsky CH-53K test vehicle
Sikorsky and the US Marine Corps have started the auxiliary power unit (APU) on the prototype CH-53K heavy-lift helicopter and expect to soon begin testing the aircraft’s three main General Electric GE38-1B engines.
The APU ignition on 23 December marked the beginning of the so-called “bare-head light off” tests phase, which involves testing the engines without the rotors connected to the rotor head, says the US Navy in a media release.
Sikorsky tells Flightglobal the main engines should be ignited one-at-a-time by the end of the month, but could be turned on as soon as next week.
The testing is being conducted at Sikorsky’s assembly and flight operations facility in West Palm Beach, Florida.
“During independent component and system testing, we have matured the aircraft systems, including electrical and avionics, hydraulics and flight controls, landing gear, propulsion, transmissions and rotors. Now we can begin testing these critical functions as an entire system,” says Mike Torok, Sikorsky’s CH-53K programme vice president, in the Navy media release.
The UTC Aerospace-supplied APU supplies the bleed air to pressurise the cabin and start the main engines, as well as power an onboard generator and activate a hydraulic pump.
The CH-53K, a 38,400kg (84,700lb) transport helicopter being developed by Sikorsky for the US Marine Corps, is powered by three 7,500shp-class GE38-1B turboshaft engines.

The CH-53K is designed to carry an external load of more than 12,210kg over a mission radius of 110nm under high and hot flight conditions, says Sikorsky.
Following bare-head testing, the aircraft’s seven main rotor blades and four tail rotor blades will be attached for the so-called “shake-down light-off” test, during which the engines will turn the blades for the first time.
Sikorsky says shake-down testing could begin within one month of the bare-head light-off tests and will likely take a couple of years to complete.
The prototype CH-53K ground test vehicle will never fly — it is anchored to the ground and outfitted with sensors at more than 1,300 locations to monitor performance, says the Navy and Sikorsky.
The bare-head and shakedown tests will prove the aircraft’s dynamic systems and help ensure the safety of test flights, says Sikorsky.
Sikorsky expects to build four flight test aircraft this year and plans to conduct the first CH-53K flight in late 2014.
Low-rate initial production of the type will likely start in 2015 and continue until 2017, and full-rate production should start between 2019 and 2022, the Navy has told Flightglobal.
The US Marine Corps has ordered 200 CH-53Ks, and expects to assign them to eight active duty squadrons, one training squadron and one reserve squadron, says Sikorsky.
Initial operational capability is planned for 2019.

NH90 closes in on 200th delivery milestone
NH Industries (NHI) is ramping up production of its NH90 transport helicopter and is closing in on the 200th delivery of the type as it looks to put the delays and contract disputes that have dogged the programme behind it.
Speaking at a Paris media event on 28 January, Guillaume Faury, chief executive of Airbus Helicopters, which has a majority stake in the NHI consortium, said the NH90 "has now overcome the difficulties of the beginning of the programme" and has entered the "industrialisation and fast delivery phase". The eventual target is a production rate of 60 aircraft per year, including those manufactured by partner company AgustaWestland, rising from nearly 50 in 2013.
The current backlog stands at over 300 aircraft, says Faury, and the company continues to "actively promote" it to potential customers.
Qatar is seen as a likely buyer and could place a 22-aircraft order for a mixture of both the TTH troop transport and NFH naval variants - alongside 20 Tiger attack helicopters - following a technical evaluation conducted by the Gulf nation last year, says Dominique Maudet, Airbus Helicopters' executive vice-president for global business and services.
Although the NH90 secured a deal in June 2013 for 34 helicopters to be operated by the French army, that is the only commitment in the last two years. Other nations, meanwhile, are looking to amend or cancel orders to reflect declining defence budgets.
Portugal is still in talks with contracting agency NAHEMA over the cancellation of its agreement for 10 troop transports, with Lisbon likely to incur a financial penalty for its decision. And although Spain will take delivery of its first NH90 TTH this year, it has yet to finalise alterations to its contract for 45 aircraft, which would see the overall order cut to 22 and the addition of a logistics support package of a similar value. Nonetheless, Faury insists that Madrid remains "very committed to the programme".
Germany too is seeking changes to its future helicopter requirements. Under a plan announced last March, it will cut the number of Tigers it intends to acquire from 80 to 57 and reduce its order for 122 NH90 TTHs to 100 aircraft in total, which now includes 18 of the maritime variant for the German navy. The modification has been agreed in principle with Berlin, says Maudet, and is now "in the hands of the contracting agencies [OCCAR and NAHEMA] to put that into place". Maudet anticipates the revised deal will be signed off in 2014.
Airbus Helicopters also remains in negotiations with New Zealand over penalties for late delivery of its eight NH90s, which were all due to have arrived by 2011. While not disclosing the detail of the talks, Maudet confirms that the potential for compensation is included within the terms of its contract.
Outside of NHI, the manufacturer is additionally hopeful that it can secure further orders in 2014 from Mexico for between six and 12 EC725 Cougar transports and 12 AS565 Panthers, says Maudet.

Sikorsky fires up main CH-53K engines
Sikorsky is moving forward with ground testing of its prototype CH-53K heavy lift helicopter, announcing it has ignited the ground test vehicle’s 7,500shp-class General Electric GE38-1B engines and spun the rotor head.
The ignition, which occurred on 24 January, is part of the “bare-head light off” tests, which involve engine tests without the rotors attached to the rotor head. asset image
Sikorsky's CH-53K ground test vehicle undergoes "bare-head light off" tests in West Palm beach in January 2014. Sikorsky.
Bare-head light off testing began in December with ignition of the ground test vehicle’s auxiliary power unit (APU).
Sikorsky’s vice president of the CH-53K programme Mike Torok calls the main engine ignition a “significant step” for the programme.
"Having independently tested the aircraft's many components and subsystems, including electrical and avionics, hydraulics and flight controls, landing gear, propulsion, transmissions and rotors, now we have begun testing these critical functions as an entire system powered by the... engines," he says.
Sikorsky says the 19,958kg (44,000lb) prototype is anchored to the ground at an outdoor test area at its facility near West Palm Beach in Florida.
The vehicle is fitted with sensors at more than 1,300 locations to help ensure it will operate safely under its own power, says Sikorsky. asset image

The ground-test vehicle will undergo tests for about two years by both Sikorsky and the US Marine Corps, the aircraft’s launch customer.
Following bare-head testing, Sikorsky will attach the seven main rotor blades and four tail rotors and begin further systems checks.
The aircraft must then pass a “formal pre-flight acceptance test” before the first flight test aircraft will be cleared to fly, says the company.
Sikorsky has four flight test aircraft under development and expects the first flight to occur late this year.
The flight test programme is expected to last three years, during which the ground test vehicle will undergo evaluation of the long-term endurance of its engines, dynamic components and survivability. The company will also study maintenance practices, Sikorsky says.
Developed for the Marine Corps, the CH-53Ks powered by three GE engines and will have a 39,900kg maximum gross weight, says Sikorsky.
The aircraft will be able to carry an external load of more than 12,200kg over a mission radius of 110nm (204km), triple the capacity of Sikorsky’s CH-53E Super Stallion, the company says.
The US Defense Department intends to purchase 200 of the aircraft, which are expected to reach initial operational capability in 2019, Sikorsky says.
The US Marine Corps intends to have eight active CH-53K squadrons, one training squadron and one reserve squadron, according to Sikorsky.
Low-rate initial production of the type will likely start in 2015 and continue until 2017, and full-rate production should start between 2019 and 2022, the Navy has told Flightglobal.
