DATE:27/10/10 SOURCE:Flight International Kiowa Warrior steals spotlight at AUSA By Stephen Trimble
After surviving two attempts to field a replacement scout helicopter, the Bell Helicopter OH-58D Kiowa Warrior is only getting stronger as the US Army considers a wide range of options for its future.
The Kiowa Warrior assumed a starring role on the service's biggest stage - the annual convention of the Association of the US Army. Service officials revealed a new "Fox" model called the OH-58F, featuring long-awaited cockpit and sensor upgrades for its 26-year-old scout helicopter fleet.
The army also announced that Bell is resuming a production line for Kiowa Warrior conversions that has lain dormant for about 15 years. The goal is to replace 43 OH-58Ds lost in accidents and combat since 2003 with remanufactured aircraft.
Both steps are strong endorsements in the future of an aircraft that could again be recommended for retirement within six months.
An ongoing analysis of alternatives, commissioned in the wake of the 2007 cancellation of the Bell ARH-70 Arapaho armed reconnaissance helicopter, is setting the course for the future of the army's scout helicopter fleet.
Army officials decline to release any new preliminary findings, but confirm that a solely unmanned solution has been ruled out.
When the study is complete in the second quarter of next year, army planners could still point in any of several directions. One option is to launch a new development programme for a high-speed aircraft, with the newly unveiled Sikorsky S-97 Raider as a top candidate.
Another option is to park the Kiowa Warrior fleet for an off-the-shelf aircraft that can meet the army's most demanding new requirement for so-called "high-hot" capability.
In mountainous Afghanistan, the OH-58D lacks enough power to fly missions when hovering out of ground effect at 6,000ft (1,830m) on a 35°C (95°F) day.
EADS North America and Lockheed Martin have teamed to adapt the UH-72 Lakota utility helicopter into an armed scout. Three of the AAS-72X demonstrators are now in development. AgustaWestland, meanwhile, would offer a militarised variant of its AW119.
But the army may decide to capitalise on its current investments in the OH-58D, which include integrating a digitally based glass cockpit and a nose-mounted Raytheon common sensor payload.
However, as the OH-58D fails to meet the new standard for high-hot performance, Bell is proposing to replace its Rolls-Royce Model 250-CR30 engine with Honeywell's HTS900-2: a 50% more powerful alternative leveraged from the cancelled ARH-70. R-R, however, has countered with an offer to increase the 250's thrust by up to 12%.
If preserving the OH-58D is the army's preferred approach, it also can look at an offer from AVX, a Texas-based start-up founded by mostly former Bell engineers.
AVX is proposing to transform the OH-58D into a compound helicopter with about 25% greater speed. The development could be made at a fraction of the cost of Bell's re-engining programme, AVX claims.
The US Army is considering a range of options for the future of the Bell Helicopter OH-58D. Picture: US Army

Second Mi-38 Prototype Begins Testing Kazan | OP-2, the second prototype of the new Mi-38 helicopter built by Moscow Mil Helicopter Plant JSC and Kazan Helicopters JSC, the subsidiaries of the Russian Helicopters holding company, has achieved its first flight. The test program that was started is proceeding well according to Kazan Helicopters specialists: the helicopter has already completed 26 ground runups and 7 hover and low speed flights over the runway.
The design of the machine undergoing flight tests was modified pursuant to the results of tests on the first Mi-38 prototype – the OP-1. The hydraulic and fuel systems have been upgraded and some changes have been made to the main rotor blades. The helicopter control system now has spring feel mechanisms of type design. As a result the helicopter is in maximum compliance with the Russian airworthiness regulations AP-29, a counterpart of FAR-29. Its handling and stability have improved. It is equipped with Pratt & Whitney Canada PW 127/TS engines and the modern Tranzas IBKV-38 avionics suite with a glass cockpit. The helicopter can also be equipped with Russian TV7-117V engines. The Mi-38 OP-2 is scheduled to be handed over to Moscow Mil Helicopter Plant for the full flight test cycle.
Moscow Mil Helicopter Plant is planning to demonstrate the Mi-38 OP-2 helicopter in 2011. Mass production at Kazan Helicopters is scheduled for 2013. The third prototype of the Mi-38 is in assembly in Kazan.
The medium multi-role cargo and transport Mi-38 is designed for passenger transportation (including VIP flights), carrying loads in the cabin and on an external sling, search and rescue, offshore, and flying hospital operations. According to design specifications, the Mi-38 will have a high payload and top speed. The Mi-38 will have a spacious passenger cabin and highly efficient engines. The labour constant for service and maintenance may be reduced thanks to a built-in automated equipment and engine serviceability control system.
The Mi-38 is a new generation helicopter that can perform up to the highest safety and comfort standards for helicopters in its class.

AgustaWestland Completes the First AW109 LUH/LOH Operators Conference
Over 40 delegates attended the first AgustaWestland AW109 LUH/LOH Operators Conference recently held at AgustaWestland’s Vergiate plant in Italy. The event brought operators and industry together to discuss the helicopter’s operations in the Far East, Africa, and Europe. Delegates were also given presentations and updates by representatives from engine and avionics suppliers Turbomeca and Thales. The delegates received briefings by AgustaWestland’s Customer Support, Engineering and Training Academy organisations and by the main AW109 LUH/LOH programme suppliers and partners. The briefings allowed industry and operators to share views and information about the aircraft’s operational effectiveness, current and future product improvements and new customer support organisation initiatives that are intended to further enhance the services and response times provided to customers. Briefings were also given on operators “real-life” experiences with the AW109 LUH/LOH in varying operational scenarios including ship board operations. Richard Nevill, AgustaWestland’s Senior Vice President Customer Support speaking after the conference said “This first AW109 LUH/LOH event was of great benefit to all participants, allowing operators and industry to openly share ideas, information and experiences that will allow us to continue to improve the service we provide and for the operators to maximise the capabilities and effectiveness of their aircraft.” The success of this event has already led to the establishment by attendees of the “AgustaWestland AW109 LUH/LOH User Group” to allow them to continue to exchange information on operational aspects and other areas of common interest. The AW109 Light Utility Helicopter (LUH) has become the world’s best selling military light-twin helicopter, with orders for over 100 helicopters so far, able to satisfy a wide range of land-based as well as sea-based requirements. The AW109 LUH offers state-of-the-art mission-dedicated technology and equipment enhancing operational effectiveness while reducing pilot workload, together with unmatched performance, reliability, availability, serviceability and safety standards. Operators use their AW109 LUHs in a wide range of environmental conditions from the tropical heat of Malaysia to the extreme cold conditions of Sweden in winter. The aircraft is also used for a wide range of roles including training, troop transport, medical evacuation, search and rescue, maritime patrol, observation, armed escort and anti-armour. Some recent notable AW109 LUH deployments include ones carried out by the South Africa Air Force and Swedish Armed Forces. Up to 16 of the South African Air Force’s AW109LUHs were deployed during the 2010 Football World Cup to provide enhanced security across the country, mainly performing low altitude patrol, utility and medical evacuation duties. The Swedish Armed Forces deployed two helicopters to the Gulf of Aden this year for anti-piracy duties with AgustaWestland actively assisting the urgent requirement by providing various modifications. The modifications included the installation of ballistic protection and sand filters as well as the development of a deployment spare parts package. The AW109 LUH is being evaluated by several potential new customers to meet their future military requirements. Source and photo: AgustaWestland

NH90 : Le point sur le programme
crédits : ALEXANDRE DUBATH - EUROCOPTER
14/01/2011
La livraison à la Marine nationale de son troisième NH90 est l'occasion de faire le point sur ce programme. Le nouvel hélicoptère a été jusqu'ici retenu par 14 pays, qui ont commandé plus de 500 machines, dont 111 en version navalisée (NFH - Nato Frigate Helicopter). Livrée à ce jour à 50 exemplaires à 6 pays, la version « terrestre » est, quant à elle, appelée TTH (Tactical Transport Helicopter). Pour la France, l'Italie, l'Allemagne, les Pays-Bas, le Portugal et la Belgique, le contrat est géré par la NAHEMA (Nato Helicopter Management Agency). Industriellement, l'hélicoptère est développé, produit et supporté par le consortium NH Industries, composé d'Eurocopter (62.5%), AgustaWestland ( 32%) et Fokker Landing Gear (5.5%).
Un programme complexe
Ce schéma a permis de fédérer les besoins de nombreux pays tout en rassemblant les forces des deux grands hélicoptéristes européens et d'une centaine de sociétés sous-traitantes de premier rang. Mais il a aussi abouti à une gestion complexe du fait du nombre importants d'acteurs étatiques et industriels impliqués. La multiplication des versions (23 au total), mais aussi les difficultés techniques inhérentes au développement et à l'intégration de nouveaux équipements, n'ont pas facilité les choses et, au final, le programme accuse plusieurs années de retard. Face aux difficultés rencontrées, une réorganisation au niveau de l'industrie, initiée en 2008, a permis de simplifier la direction et l'administration du programme pour accélérer les prises de décision. Depuis, les difficultés semblent largement surmontées.
Premières livraisons en 2010 du NFH
Concernant la version NFH, 111 hélicoptères ont donc été commandés, soit 46 pour l'Italie, 27 pour la France, 20 pour les Pays-Bas, 14 pour la Norvège et 4 pour la Belgique. Les marines néerlandaise et française ont touché leurs premiers appareils en 2010. Chacune dispose actuellement de 3 machines. En 2011, l'Italie et la Norvège recevront à leur tour leurs premiers NH90, la Belgique devant quant à elle être servie en 2012. L'aéronautique navale tricolore, pour laquelle 27 « Caïman » ont été commandés, prévoit, à l'issue d'une campagne d'expérimentation, une mise en service fin 2011.
Deux standards
Lutte antinavire et anti-sous-marine, transport d'assaut, logistique, secours en mer, surveillance maritime... Le NH90 sera un appareil extrêmement polyvalent permettant de remplacer par un même hélicoptère nettement plus performant le Lynx, le Super Frelon ou encore le Sea King. Le passage d'une configuration à une autre est facilité par l'usage de kits, avec une reconfiguration automatique des calculateurs de l'hélicoptère en fonction de la configuration choisie. Présentant une masse d'environ 10 tonnes, l'autonomie du NH90 est supérieure à 4 heures, soit 480 nautiques franchissables.
Les premiers Caïman Marine opérationnels cette année au sein de la flottille 31F ne disposeront toutefois pas, dans un premier temps, de toutes les fonctionnalités. Les premiers NFH sont, en effet, livrés au Step A, qui comprend toutes les fonctions majeures, à l'exception des armes. Le standard final, appelé Step B, doit être livré en 2012 et permettra notamment la mise en oeuvre missiles et torpilles, d'un sonar trempé FLASH et de bouées acoustiques. On notera d'ailleurs qu'allié aux frégates de nouvelle génération, comme les FREMM, le NH90 constituera une menace redoutable pour un sous-marin hostile.
Les spécificités de la version navale
Commandes de vol électriques, fuselage en composite, capacités anti-crash, résistances aux ambiances d'environnement et d'électromagnétisme sévères, système de contre-mesures... La base du NFH est commune avec la version terrestre du NH90. Son cockpit très ergonomique est équipé d'écrans multifonctions et son fuselage en composite le rend plus léger et plus discret face aux radars. Par rapport au TTH, le NFH dispose d'un certain nombre de particularités, liées aux missions qui lui seront confiées et à l'environnement dans lequel il évoluera. La version navalisée du NH90 comprend un radar panoramique (360°) offrant une vision étendue du domaine maritime et optimisé pour la lutte antinavire comme ASM (détection de périscopes). Il dispose aussi de radios et liaisons de données spécifiques (L11), ainsi que d'un système de veille électro-optique (boule FLIR) pour la détection et le pistage de cibles, de jour comme de nuit.
Taillé pour les frégates
Pour la mise en oeuvre sur bâtiments de surface, l'hélicoptère est doté d'un train d'atterrissage renforcé, d'un harpon pour les appontages, ainsi que d'un système automatique de repliage des pales et de la poutre de queue pour le stockage dans le hangar des frégates. Cette catégorie de bâtiments est, d'ailleurs, « dimensionnante » en termes d'appontage, surtout par mauvais temps, les mouvements de la plateforme provoquant d'importantes contraintes sur les trains. Une campagne de qualification au delà du cercle arctique a, notamment, été mené en 2008 sur une frégate norvégienne par mer forte avec appontages par différents angles de vent par rapport à l'hélicoptère.
En matière d'armement, les NH90 NFH pourront mettre en oeuvre des missiles antinavire de type Marte Mk2/S (Italie et Norvège) ou ANL/FASGW (projet franco-britannique de nouveau missile antinavire léger). Dans le domaine de la lutte anti-sous-marine, l'appareil sera doté de torpilles MU90 (France et Italie), Mk46 (Pays-Bas) et Sting Ray (Norvège). Enfin, pour les missions de contre-terrorisme et de lutte contre le narcotrafic ou la piraterie, le NH90 pourra embarquer un tireur d'élite.
La version soutien
Dans sa version transport (ou soutien), le NFH pourra accueillir 14 soldats en plus de son équipage. Cette variante disposera d'une rampe arrière et pourra assurer le transport de charges OTAN grâce à un système de montée de charges par treuil avec rails intégrés. Le NH90 sera également à même de réaliser des évacuations médicales, y compris en zone de combat, ainsi que des missions de sauvetage maritime. Pour cela, l'équipage s'appuiera notamment sur le détecteur infrarouge de la boule FLIR et sur le radar panoramique, le treuil permettant de transférer du personnel, des civières ou du fret.

New tests for the Cyclone
The new CH-148 Cyclone, which arrived at Shearwater January 6, will be undergoing further testing on board HMCS Montréal. The tests will last several weeks, under the direction of Sikorsky International Operations Inc., prime contractor on the Maritime Helicopter Project. The CH-148 Cyclone will provide anti-submarine surveillance, and will have enhanced search and rescue and tactical transport capabilities. Tests of the operational limits of a ship-borne helicopter will make a notable contribution to the Project, which seeks to replace the existing Sea King fleet that has been in service since the 1960s. HMCS Montréal will serve as a prototype during the tests, and the vessel has undergone considerable modification so that the tests may be conducted in optimal fashion. Since the modifications were made, HMCS Montréal has successfully completed Air Work-Ups, which tested the abilities of the crew to conduct routine flying operations, respond to in-flight emergencies and to a helicopter crash, and combat shipboard fires. This new stage in the Project testifies to the Canadian Government’s desire to provide the Canadian Forces with modern equipment that can be rapidly deployed to provide international security and react to threats to Canada and to North America

Republic of Korea Air Force Receives First Lockheed Martin Sniper® Pods
FORT WORTH, TEXAS (April 18, 2011) – Bell Helicopter, a Textron Inc. company (NYSE: TXT) announces the first flight of its OH-58 Block II demonstrator at its Xworx research and development facility in Fort Worth, Texas on April 14, 2011. "The flight was flawless and completed according to plan," said Cathy Ferrie, Director of Bell Helicopter’s Xworx facility. "The Block II is a significant leap forward in performance for the Kiowa Warrior platform and will absolutely make this a 21st Century airframe for the 21st Century soldier." Bell Helicopter is developing this OH-58 Block II fleet representative demonstrator to facilitate prototyping activities in anticipation of a U.S. Army future requirement of 6K/95 performance. The Block II OH-58 provides an attractive, cost efficient alternative for the U.S. Army and U.S. taxpayer, and will demonstrate Bell helicopter’s ability to meet or exceed all performance requirements for the Army’s Armed Aerial Scout. Bell Helicopter is developing this aircraft with its own resources and at no cost to the government. The Block II demonstrator takes an OH-58 Kiowa Warrior and makes it a fast fielding, low risk and lowest cost solution to achieve 6,000ft and 95 degree performance. The “high-hot” performance can be attained with propulsion and drive training upgrades to the existing platform. This upgrade program builds upon the F model Cockpit and Sensor Upgrade Program (CASUP) improvements by adding a new engine, transmission and rotor system.“ By continuing to upgrade the OH-58F into a Block II program, the Army will save money that they can invest in future technologies or future platforms,” said Stephen Eppinette, Army business development manager. “It will also give the Army and the tax payer a return for the money invested in the F model program.” Along with the performance upgrades, the Block II will adopt fully integrated condition-based maintenance (CBM) technologies so that the aircraft will have higher performance, increased safety, and greater operational readiness while reducing life-cycle costs. With more than 750,000 fleet combat hours, the OH-58D Kiowa Warrior is a combat- proven aircraft that is safe, rugged and reliable, maintaining the highest readiness rate of any Army helicopter operating in Afghanistan while simultaneously having the highest operational tempo

Sikorsky Delivers S-70iTM BLACK HAWK Helicopters to Launch Customer
August 05, 2011
MIELEC, Poland - Sikorsky has delivered three S-70™ BLACK HAWK helicopters to an undisclosed customer. The helicopters — assembled, completed to customer specifications, and flight tested at Sikorsky’s production facility in Mielec, Poland — are the first-ever deliveries of the international variant of Sikorsky’s iconic BLACK HAWK helicopter. Sikorsky is a subsidiary of United Technologies Corp. (NYSE: UTX).
The three medium-lift aircraft are among six S-70i BLACK HAWK aircraft assembled and flight tested at PZL Mielec since the Polish company became part of U.S.-based Sikorsky Aircraft Corporation in 2007. They departed Poland’s Rzeszów-Jasionka Airport inside an Antonov An-124 Ruslan cargo aircraft following a week of flight acceptance activities in the skies over Poland.
“PZL Mielec has proven it can build and flight test a new variant of the BLACK HAWK helicopter to the very highest standards,” said Robert Mastronardi, S-70i senior program manager, Sikorsky Military Systems. “The aircraft acceptance process confirmed the high quality of these aircraft and professionalism of the PZL Mielec team.”
The company plans to expand production to 10 aircraft in 2012, and to 22 helicopters in 2013.
The S-70i helicopter can be configured for multiple missions, such as troop support, humanitarian relief, VIP transport, search and rescue, medical evacuation, and armed patrol.
“The S-70i helicopter features typical BLACK HAWK reliability, and excellent performance coupled with the most modern avionics to reduce pilot workload,” said Leszek Pawuła, S-70i test pilot at PZL Mielec. “The aircraft provides a safe and stable platform for equipment needed to perform many varied missions, retaining its extreme maneuverability. It’s pure pleasure to fly this helicopter.”
The aircraft’s two T700-GE701D engines, digital avionics, and modern wide chord rotor blades produce the same power and lift performance as the UH-60M BLACK HAWK aircraft flown by the U.S. Army.
Advanced avionics — also standard to the S-70i BLACK HAWK helicopter — include a fully integrated digital cockpit, a dual digital automatic flight control system and coupled flight director, an active vibration control system, and a dual GPS/INS system with digital map.
A proven performer, the BLACK HAWK consistently maintains reliability rates of approximately 85 percent, even when flying in harsh environments.
Since 2007, Sikorsky Aircraft Corporation has invested more than $100 million to establish a modern production operation at the PZL Mielec facility, increasing employment by 30 percent. Since the arrival of the BLACK HAWK production, PZL Mielec has increased its employment numbers and now employs over 2,000 people. As a key investor in the Polish “Aviation Valley,” Sikorsky has stimulated the development of the domestic aviation industry.
Sikorsky Aircraft Corp., based in Stratford, Conn., USA, is a world leader in helicopter design, manufacture and service. United Technologies Corp., based in Hartford, Conn., USA, provides a broad range of high technology products and support services to the aerospace and building systems industries.

Software Change Gives V-22 Pilots More Lift Options
9/20/2011
Printer friendly
A test team from the V-22 Joint Program Office spent about six weeks in Logan, Utah confirming that a small software change will result in more lift capability for the Osprey.
The actual change, which is barely observable to the eye, calls for the V-22 rotors to be tilted about four degrees outward. This change reduces the air flow from the rotors over the wings, which allows the V-22 to carry more weight and achieve greater overall performance in hover mode.
“We did see the performance gain from the software change that we expected,” said Trevor Strand, V-22 flight test engineer. “It gives the pilot more options. He can either carry more fuel, more troops, go to higher altitudes, or some combination of the three.”
Strand led the 30-person integrated test team (ITT) during the off-site test at the Logan-Cache Airport during July and August. The ITT flew 25 test flights in 31 days. This effort was the result of about two years of work by NAVAIR engineers to improve the hover performance of the V-22.
The software change that was measured and confirmed in Logan has already been implemented into some MV-22s. The plan is to upgrade all V-22s by the end of the year. The test team is currently updating performance documentation for V-22 operators.
The V-22 team averages about one off-site test event a year. Considerable research and planning goes into finding just the right spot.
“We don’t like to do all of our hover performance testing at sea level because the proprotor is not working at its maximum limits,” Strand said. “We don’t want to max out the engines at a very high altitude like 9,000 feet either so the ideal location is somewhere in between.”
At about 4,400 feet in elevation, Logan provided an ideal test location including the required wind conditions.
“It was one of the most successful off-sites that we’ve ever had,” Strand said.
The test team took one MV-22 Osprey to Logan for the test and it was available 100 percent of the time.
“The entire team did an outstanding job,” said Mike Caram, V-22 test manager. “It was a very productive off-site with a lot of great work on everyone's part.”

IN FOCUS: MV-22 makes Dubai debut in bid for export deals By: Stephen Trimble Washington DC 9 hours ago Source: flightglobal
The Bell Boeing joint venture will bring the MV-22 Osprey tilt-rotor to the Dubai air show for the first time, as it continues to push for the type's first export sale.
Saudi Arabia has been named by programme officials previously as one of 10 to 15 possible foreign buyers of the MV-22. In the last five years, Saudi officials have come close to acquiring transport and combat search and rescue helicopters from both France and Russia, but in each instance a deal was never closed.
The type has seen off many of its critics after performing admirably on deployment in Iraq, Afghanistan and Libya
Bell Boeing may be hoping to fill part of the Saudi military's rotorcraft gap with the MV-22, which can take off and land vertically and fly as fast as some fixed-wing turboprops.
If there are other possible buyers in the region, the programme has not identified them. But the joint venture manufacturing the Osprey is clearly pleased to bring the MV-22 to the region's largest showcase for aerospace products. "The Dubai air show is one of the world's fastest-growing aerospace events, and it presents an excellent opportunity for Bell Boeing to showcase the tilt-rotor Osprey's one-of-a-kind capability, unique value proposition and outstanding record of operational performance with a new audience," the company says. The MV-22 will join the Xian MA-600 regional airliner and the United Arab Emirates-based Quest helicopter among the aircraft making a debut at the show.
Bell Boeing and the US Naval Air Systems Command (NAVAIR), which acquires the MV-22 on behalf of the US Marine Corps, has been trying to attract foreign buyers since 2006. Two MV-22s flew across the Atlantic in July 2006 to make a debut appearance at the Farnborough air show in the UK, which has also been named a potential buyer.
AGGRESSIVE MARKETING
Earlier this year, the marines attended the Canadian International Air Show with the MV-22, as Ottawa also looks to its needs. But so far foreign sales have not materialised. For the MV-22 programme, closing an export deal within the next two years is more essential than ever. US government and company officials have been aggressively marketing the aircraft abroad for at least five years.
Finding foreign buyers is more important now than ever for the MV-22 programme to meet production targets. NAVAIR and Bell Boeing are currently negotiating a five-year procurement deal starting in fiscal year 2013 for 122 aircraft. Such multi-year deals normally require the contractor to offer a 10% price reduction, compared with the placement of a series of annual purchases. But ongoing budget reviews are threatening to slash between six and 24 aircraft from the total, however, Marine officials believe Bell Boeing can still meet the cost reduction targets with a reduction of even 24 aircraft - but they are also concerned that further MV-22 cuts are still possible. As the numbers drop, Bell Boeing will be challenged to meet the cost reduction targets required to get approval for the multi-year contract.
One possible solution to the production cuts problem is a wave of foreign purchases. The export market for the MV-22 has been slow to unfold, as the USMC has spent the past five years answering several questions about the value of the tilt-rotor aircraft.
In combat deployments to Iraq, Afghanistan and Libya since 2006, the MV-22 has proven wrong many of its critics. It has compiled the best safety record of any rotorocraft operated by the navy and marines. There have been no reports of the aircraft entering vortex ring state - the aerodynamic problem that caused the programme's deadliest crash during development testing in 2000. Moreover, the tilt-rotor's unique combination of speed and vertical landing ability has also proven critical in several operations. These included the rescue of a downed US Air Force Boeing F-15E Strike Eagle crewmember in Libya in late March.
Questions about the aircraft's safety have largely shifted to its cost and the maturing of the Bell Boeing supply chain. But the programme has achieved dramatic progress in these areas within the last nine months, according to the USMC.

Development of the multi-role NH90 Tactical Transport Helicopter is formally completed with its approval in the final operational configuration
The NH90 program has reached a major milestone with the declaration of compliance for the NH90 TTH (Tactical Transport Helicopter) variant’s Final Operational Configuration, This marks the NH-90 TTH’s development completion, and enables deliveries to begin before year-end in the helicopter’s full operational definition.
Marignane, 08 November 2011
“The milestone marks the most important achievement in the life of the NH90 program. NH90, the most modern rotary-wing aircraft in its class and the largest military helicopter program ever undertaken in Europe, offers now its full range of operational capabilities to the military forces” stated Lutz Bertling, the President and CEO of Eurocopter, which is a member of the NH90 industrial team. “Completing the NH90 TTH’s compliance process confirms this multi-role helicopter will meet the specifications and operational requirements of the founding customers.”
The declaration of compliance was issued by the NATO Helicopter Management Agency (NAHEMA), which is the North Atlantic Treaty Organization’s function that manages the NH90 acquisition for the participating countries. With this go-ahead, the initial NH90 TTH variant in the final operational configuration is to be received by the French Army. It will be followed by the startup of deliveries in 2012 to Italy, Belgium and Germany.
The new-generation NH90 TTH is designed for use in a wide range of demanding missions, including logistics and utility transport, combat search and rescue, casualty and medical evacuation, electronic warfare, special operations and counter-terrorism. In its approved final operational configuration, the helicopter offers a matured avionics system, allowing day and night missions with no major restrictions; full military communications system functionality for interoperability in foreign operations; a complete set of technical publications; and the approval for overseas deployments by ship.
