Le Boeing F-15 QA réalise son premier vol

Boeing a effectué avec succès le premier vol du chasseur F-15QA, version la plus avancée du F-15 développée pour l'armée de l'air qatarie (QEAF). L'avion a démontré ses capacités au cours d'un vol de 90 minutes. L'appareil a décollé et a atterri de l'aéroport international Lambert à Saint-Louis.

Cure de jouvence pour le F-15

Enfin une bonne nouvelle pour Boeing, même si le F-15 n'est plus vraiment ce que l'on peut appeler un appareil de première fraîcheur. L'avionneur de Saint Louis (ex division McDonnell Douglas en conséquence) a effectué avec succès le premier vol du chasseur F-15QA, version la plus avancée du F-15 développée pour l'armée de l'air qatarie (QEAF). L'avion a démontré ses capacités au cours d'un vol de 90 minutes. L'appareil a décollé et a atterri de l'aéroport international Lambert à Saint-Louis.

« Nous sommes très fiers de cet accomplissement et nous nous réjouissons avec beaucoup d'enthousiasme des succès continus de ce programme », a déclaré le colonel Ahmed Al Mansoori, commandant de l'escadre F-15 de la QEAF. « Ce premier vol réussi est une étape importante qui rapproche nos escadrons d'un pas vers le pilotage de cet avion au-dessus du ciel du Qatar. »

L'équipe d'essais en vol de Boeing, dirigée par le pilote d'essai en chef Matt Giese, a mis en place une liste de vérification précise de la mission pour tester les capacités de l'avion multirôle. L'avion a démontré sa maniabilité lors de son décollage vertical en tirant neuf G, soit neuf fois la force de la gravité terrestre, au cours de ses manœuvres subséquentes dans l'espace aérien d'essai. Les vérifications des systèmes tels que l'avionique et le radar ont également été couronnées de succès. Une équipe d'essai qui surveillait les données en temps réel a confirmé que l'avion s'était comporté comme prévu.

6,2 MD$ pour 36 avions

Le département américain de la Défense a attribué à Boeing un contrat de 6,2 milliards de dollars en 2017 pour la fabrication de 36 avions de chasse F-15 pour la QEAF. Boeing commencera à livrer des avions au client en 2021. De plus, Boeing a obtenu un contrat de vente militaire à l'étranger de l'US Air Force en 2019 pour les équipages F-15QA et la formation à la maintenance pour la QEAF.

Le F-15QA apporte à ses exploitants des technologies modernes telles que les commandes de vol CDVE (commandes de vol électriques), cockpit numérique, capteurs modernisés, radars et des capacités de guerre électronique. L'augmentation de la fiabilité, de la durabilité et de la maintenance permet aux opérateurs de défense de rester en avance sur les menaces actuelles et en évolution.

Vers le F-15EX pour l'USAF

Gr'ce à des investissements dans la plate-forme F-15QA et un partenariat avec l'US Air Force, Boeing se prépare maintenant à construire une variante nationale du chasseur avancé, le F-15EX. Huit appareils devraient être assemblés pour commencer, les plans futurs prévoient jusqu'à 144 appareils.

  • JSTARS Recap is officially dead

    JSTARS Recap is officially dead

    By: Valerie Insinna LONDON — The Air Force scored a major win in the 2019 defense authorization bill: Not only will it be able to cancel the JSTARS recap program, it is getting additional funds for its alternative effort called Advanced Battle Management System. However, the service will have to make some concessions in terms of its plans to retire the existing E-8C Joint Surveillance Target Attack Radar System fleet, which is used for ground surveillance and command and control missions. The Air Force had planned to retire three E-8Cs in 2019 that had become “hangar queens” cannibalized for spare parts for the rest of the fleet, Air Force Secretary Heather Wilson said earlier this year. However, according to the new defense policy bill unveiled Monday, it will not be able to retire any of the 17 planes until “increment 2” of the ABMS system is declared operational, although Congress will allow the Air Force secretary to phase out planes on a case-by-case basis if an aircraft is no longer mission capable. While the Air Force has not spelled out to the public exactly what comprises its ABMS plan, it involves a host of different upgrades for existing platforms —for instance the MQ-9 Reaper and E-3 AWACS early warning aircraft — that will allow them to network together in new ways. A congressional aide told Defense News on July 24 that the Air Force have three ABMS increments in a series of classified briefings to members of Congress' defense committees. Phase one, which lasts from now until about 2023, involves upgrades to datalinks and some space-based technologies, as well as linking sensors from several stealth platforms and drones together, the aide said. Increments 2 and 3 quickly get into more classified territory, said the aide, who declined to provide greater specifics. The defense authorization bill would accelerate ABMS by adding $120 million for six MQ-9 Reapers, which the aide said could be used to help boost the architecture's ability to prosecute targets during a low-end conflict. It also included $30 million to continue development of the ground moving target indicator radar developed by Northrop Grumman for the JSTARS recap program. In addition, Congress levied a number of other restrictions and reporting requirements on the Air Force as part of the FY2019 National Defense Authorization Act, including: The Air Force's plan for modernizing and sustaining the current JSTARS fleet, including how it will increase the availability of the E-8Cs to support demands worldwide. Quarterly reports from the Air Force secretary on the progress of ABMS. Certification by the defense secretary that the Air Force has a long term funding plan that will allow it to retain JSTARS and that the ABMS acquisition strategy is executable. A report on ABMS from the Government Accountability Office, which provides independent oversight to Congress. The report will review the maturity of the plan and any risk associated with fielding or funding it. A directive to the Pentagon's Cost Assessment and Program Evaluation office to reexamine the cost and schedule for restarting a re-engine effort of the E-8C, which had begun in 2008 but was since abandoned. The Air Force “procured three ship-sets of engines, after investing $450.0 million, and the engines remain unused,” even though “the legacy E-8C engines are the number one issue driving excessive non-mission capable maintenance metrics for the E-8C fleet,” the bill stated. The end of the JSTARS recap program is bad news for Lockheed Martin, Boeing and Northrop Grumman, who were each vying for the prime contractor spot and the $6.9 billion contract for engineering, manufacturing and development. A total of 17 new planes were planned to be built throughout the program. Over the past year, Air Force leaders grew disenchanted with JSTARS recap, saying that new battle management planes would not be survivable in future, contested battlespaces. But while the Senate defense committees leaned in to support ABMS, House lawmakers sought to force the service to keep going with JSTARS recap. Will Roper, the Air Force's top acquisition official, told Defense News on July 17 that he was hopeful that Congress would move forward with ABMS. However, he still acknowledged that the Air Force had never modernized a “system of systems” like ABMS before. “It definitely needs to be a program where we embrace failure up front and prototype, because there's going to be a lot of learning to do about how do you make things work together as a team,” Roper said. “We get a sense of how commercial industry is solving it and I imagine we can use a lot of their lessons learned, but probably not all of them.” Infighting in Georgia What was once a disagreement between the House and Senate seems to have turned into a fight among the members of the Georgia delegation. In a surprising move, Republican Rep. Austin Scott pointed the finger at Sen. David Perdue, a fellow Georgia Republican, for allowing the recap program to be cancelled. Georgia's Robins Air Force Base is home to the 461st Air Control Wing, the joint Air Force-Army unit that operates JSTARS. “When Senator Perdue [...] withdrew his support of this program which the Georgia Congressional Delegation – including Senator Perdue – has overwhelmingly supported throughout the last seven years, it effectively ended the program,” said Scott. “Unfortunately [...] the replacement aircraft will not be fielded, forcing a higher risk to our men and women in uniform by continuing to fly the 48 year old legacy JSTARS aircraft which are in need of recapitalization.” Perdue hit back in his own statement, saying that ABMS is a better long term solution for Robins. “The Advanced Battlefield Management System will give us the capability to access both restricted and non-restricted airspace. This is a necessity in supporting our troops in harm's way as well as our overall intelligence gathering,” Perdue said. “With the solution I support, we save JSTARS jobs, maintain the JSTARS fleet into the next decade, accelerate the implementation of ABMS, and gain a new mission for Robins. All of this guarantees a very bright future for my hometown base.” https://www.defensenews.com/air/2018/07/24/jstars-recap-is-officially-dead/

    NFAC Tests Next-Generation Military Helicopter

    Wind Tunnel Test Designed To Validate The Aerodynamic Performance And Flight Mechanics Of Sikorsky's X2 Technology Aircraft The U.S. Army is looking to improve its aviation technology and recently called upon the AEDC National Full-Scale Aerodynamics Complex at Moffett Field in Mountain View, CA, to advance this effort. Engineers from Sikorsky Aircraft Corporation and The Boeing Company, in partnership with the U.S. Army Combat Capabilities Development Command Aviation & Missile Center Army Aviation Development Directorate, recently conducted a series of tests at NFAC to support the development of the SB>1 DEFIANT, a military helicopter being developed for the Army's Joint Multi-Role Technology Demonstrator (JMR TD) program. The goal of this wind tunnel test was to validate the aerodynamic performance and flight mechanics of Sikorsky's X2 Technology aircraft. These configurations, which are being utilized on the SB>1 DEFIANT, include a lift-offset coaxial rotor system, composite fuselage and rear-mounted pusher propulsor that provides increased speed. The SB>1 DEFIANT, which made its first flight in March, is a technology demonstrator for a medium-lift utility helicopter. Future uses of this type of air vehicle could include attack and assault, troop transport or MEDEVAC. The testing was conducted throughout the first half of 2019 and concluded in mid-June. To accomplish the tests, a 1/5 scale model of the SB>1 DEFIANT airframe with powered coaxial main rotors was placed in the NFAC 40- by 80-foot wind tunnel. Measurements included forces and moments on the various components, as well as fuselage, empennage and blade surface pressures. David Wang, NFAC test engineer, said the recent tests expanded on data collected from a JMR wind tunnel entry conducted at NFAC in 2016 by gathering data at faster speed ranges. “From the NFAC perspective, the wind tunnel test was successful,” Wang said. “The test customer was able to collect performance and handling qualities data for their subscale model up to their maximum design flight speed.” Data collected during the recent tests is undergoing review and analysis. It is unknown at this time if there will be future testing of the SB>1 DEFIANT model at NFAC. The full-scale SB>1 DEFIANT flight demonstrator is currently undergoing ground and flight tests at Sikorsky's flight test facility. According to the Sikorsky-Boeing JMR Team, data from SB>1 DEFIANT will help the Army develop requirements for new utility helicopters expected to enter service in the early 2030s. A previous DOD study concluded that upgrades to the aging DOD rotary wing aviation fleet would not provide the capabilities required for future operations. Significant improvement in several attributes of fleet aircraft, such as speed, payload, range, survivability and vertical lift are required to meet future needs. It was determined this improvement could be achieved through application of new technologies and designs. To accomplish its goal, the Army has been executing a science & technology (S&T) effort to mitigate risk associated with maturity of critical technologies, feasibility of desired capabilities and cost of a technical solution. An aspect of this effort is the air vehicle development associated with the JMR TD program. JMR TD is the alignment of Army Aviation's S&T with the Future Vertical Lift initiative, which seeks to develop a new family of system to modernize and replace the government's current fleet of rotorcraft. According to the Army, the intent of the JMR TD is to mitigate risk for the Future Vertical Lift program through means that include the testing of advanced technologies and efficient vehicle configurations. NFAC, managed and operated by Arnold Engineering Development Complex (AEDC), is the largest wind tunnel complex in the world. It consists of both the 40- by 80-foot and 80- by 120- foot wind tunnels. These tunnels, which share a common drive system, are primarily used for aerodynamic and acoustic tests of rotorcraft and fixed wing, powered-lift V/STOL aircraft and developing advanced technologies for these vehicles. Both subscale and full-scale models are tested at NFAC. The speed range of the 40- by 80-foot wind tunnel test section is continuously variable from 0 to 300 knots, while the speed range in the 80- by 120-foot wind tunnel section is continuously variable from 0 to 100 knots. http://www.aero-news.net/index.cfm?do=main.textpost&id=021bcb83-4df9-4253-b7a3-ff3805b7b16a
