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.

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.

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.

NHIndustries a livré ce matin le 190ème hélicoptère NH90. C'est une machine en configuration TTH (transport de troupes) qui a ainsi été réceptionnée par le gouvernement italien, selon le consortium industriel regroupant Airbus Helicopters (62,5%), AgustaWestland (32,5%) et Fokker (5,5%).
Le cap des 200 machines livrées pourrait être franchi le mois prochain, à l'occasion du salon aéronautique ILA de Berlin. Sur les 190 engins livrés à ce jour, 36 l'ont été en configuration "navale" NFH.
Programme européen complexe, le NH90 a pour l'heure été livré en pas moins de 23 sous-versions à ses différents clients, depuis les six sites d'assemblage industriels existants dans le monde. Un véritable casse-tête en termes de qualification et d'industrialisation, dont tous les acteurs semblent aujourd'hui avoir pris conscience.
Côté industriel, un vaste programme de rationalisation est en cours pour réduire au maximum les écarts de configurations mais aussi accélérer les cadences. Quarante-trois machines avaient été livrées en 2013, une cinquantaine devraient l'être en 2014 (cf. A&C n°2390).
Dernier client potentiel en date : le Qatar, qui a annoncé fin mars son entrée en négociations exclusives avec NHI pour l'achat de 22 hélicoptères, dont 12 NH90-TTH et 10 NH90-NFH en version navale.

NH Industries plans 'simplified' NH90 for future customers
Complexity has been the hallmark of the NH90 helicopter programme virtually from the outset. Its 13 customers – a total that includes one nation still working through a contract reduction and another looking to cancel its order entirely – have so far ordered 26 distinct variants of the 10.6t rotorcraft.
The unnecessarily sprawling nature of the programme, coupled with the three-way NH Industries consortium comprising Airbus Helicopters, AgustaWestland and Fokker and its six production sites, have all contributed to a programme that at times appeared to be lurching from crisis to crisis.
However, as the company marks delivery of the 200th example – a troop transport TTH model for the Belgian air force – and successful deployments to Afghanistan, it appears to have turned a corner. Now it is looking to simplify its offering to potential customers while additionally proposing upgrades and ensuring in-service support.
Speaking on 23 June at an operators’ conference at Bückeburg air base near Hanover, Vincent Dubrule, president of NHI, said it is now proposing “a unique but flexible configuration of the NH90”.
Dominic Perry/Flightglobal
The new baseline helicopter would be no less capable than those already delivered, says Dubrule, but would allow potential operators to “plug in whatever equipment they want” without the need to “restart from scratch” on every different model.
It is likely to make its debut with Qatar, which is currently in negotiations with NHI for an order for up to 22 examples: 12 TTHs and 10 of the NFH naval variant.
“The configuration...will start with them. We will base [it] on what [Qatar] wants but we can descope it or rescope it for other prospects,” he says.
Those negotiations are progressing, says Dubrule, with the aim of finalising the contract by the end of the year. Deliveries would then start in 2017-2018.
Dubrule says that with operators having flown around 50,000h and the programme having reached the 200th delivery milestone, the NH90 is approaching its mature phase.
“It is a step and now we deliver [mainly] final configuration helicopters – it is not a development or [initial operating capability] helicopter,” he says.
Last year, NHI delivered 50 aircraft and will maintain a similar level of production in 2014 as it tackles the over 300 NH90s still in its backlog. At this rate – and with future customers still to come – final assembly work stretches to at least 2020, says Dubrule.
Now, however, it is focused on sustaining those rotorcraft already delivered and “working with customers” to improve fleet availability and solve “some teething issues they have”.
Additionally, NHI is consulting with its operator base over potential enhancements to the helicopter. Ideally, these would be requested by multiple nations in order to spread development costs, he says.
Peter Harris, NHI's head of customer satisfaction, says possible requirements so far have included improvements to the type’s electro-optical sensors and data links enhanced to the Link 22 standard. Additional battlefield-wide communications systems to improve interoperability with both special forces and unmanned air vehicles may also be needed, he adds.
However, he says, the performance of the NH90 and its engines are seen as a “strong point” by operators, particularly in the hot and high conditions of Afghanistan.
NH Industries
So far, two nations – Italy and Germany – have deployed the type to Afghanistan as part of the NATO-led mission there.
Lt Col Kai Eggert was a squadron leader when the German army last year sent four TTHs to Mazar-e-Sharif to operate in a forward medical evacuation role. The aircraft have logged 900h in theatre, he says, with pilots generally full of praise for the NH90.
“We were pretty convinced and surprised by the amount of support the aircraft provides to the pilot,” he says. “The feedback was all in all very positive but some things needed to be improved, for instance the environmental control system.
“Our complaints have been taken into account very seriously and within less than three months those issues have been solved and those parts that needed improvement have been replaced,” he says.

Premier vol du Mil Mi171A2 !
Moscou, l’hélicoptériste russeVertolety Rossii (Russia Helicopters) Mil Mi a achevé le premier vol du Mil Mi-171A2 marquant ainsi, une nouvelle étape importante dans la commercialisation de l’appareil.
Le Mil Mi 171A2 :
Le Mi-171A2 est la dernière variante de la grande famille des Mi-8/17. L’appareil a été donc sensiblement modifié par rapport au Mi-8, Mi-17 et son prédécesseur Mi -171A1. Avec une masse maximale au décollage de 13t et la capacité de transporter 24 passagers, le Mi-171A2 dispose de nouveaux moteursKlimovVK-2500PS-03 avec FADEC, plus économiques et plus puissants que les actuelsKlimov TV3-117. La nouvelle hélice sustentatrice du nouvel hélicoptère est réalisée avec des matériaux composites, ce qui augmente sensiblement sa fiabilité et sa durée de fonctionnement. Le nouvel équipement facilite le pilotage de la machine, permettant de réaliser de nouveaux régimes de navigation et de pilotage. Quant à l’équipage de l’hélicoptère, il a été réduit de 3 à 2 personnes. Le nouvel appareil est équipé d’un système de navigation permettant d’assurer des vols dans n’importe quelles conditions météorologiques.
La production en série de l’hélicoptère Mi-171A2 devrait commencer à l'usine d’Oulan-Oude (république de la Bouriatie, Transbaïkalie) après sa certification en 2015. L’usine de Klimov devrait pendant ce temps mettre en place la production en série des moteurs du nouveau modèle.
Le consortium russe « Russian Helicopters » a annoncé le 12 mai 2015 le lancement de la production en série de l'hélicoptère lourd Mi-26T2. L'appareil sera produit à Rostvertol.
Le Mi-26T2 est une version modernisée du Mi-26, un hélicoptère d'une masse maximale de 56 tonnes ayant effectué son premier vol en 1977. Une nouvelle avionique a été intégrée afin de réduire l'équipage (de 5 à 2 ou 3 personnes) et de permettre les vols de nuit. Selon son constructeur, la nouvelle version de l'appareil est équipée d'un cockpit numérique avec écrans LCD. Les commandes de vol ont également été modernisées.
Les travaux de modernisation ont été conduits par les bureaux de Moscou de la société Mil. L'appareil a effectué son premier vol en 2011. Selon « Russian Helicopters », le Mi-26T peut emporter une charge de 20 tonnes en soute ou sous élingue.
Dans le domaine militaire, « Russian Helicopters » commercialise également le Ka-226T (qui vient d'être choisi par l'Inde), le Mi-28E, le KA-52, le Mi-35M, le KA-27, le KA-31, le Mi-8/17 et le Mi-26.
