Graham Warwick Sikorsky is emphasizing growth capability to stay ahead of evolving threats as it unveils its offering in the U.S. Army's Future Attack Reconnaissance Aircraft (FARA) competition, the Raider-X. The coaxial rigid-rotor compound helicopter is a development of the S-97 Raider prototype now in flight testing. The Raider-X is about 20% larger, with a 14,000-lb. gross weight compared with 11,000 lb. for the S-97, and a 39-ft. rotor diameter compared with 34 ft. for the Raider. The Army requires a rotor diameter of no more than 40 ft. so that FARA can fly between buildings in urban combat. The Raider-X will exceed the FARA's threshold maximum speed of 180 kt. Sikorsky is not saying how fast it will fly, but notes the S-97 has reached 215 kt., and 207 kt. in level flight—exceeding the 205 kt. target in the Army's initial capability document, says Tim Malia, director of Future Vertical Lift - Light. The Army subsequently reduced the threshold maximum speed to enable a wider competition for the FARA program. But Malia says the greater speed and payload capability of Sikorsky's X2 coaxial rigid-rotor compound configuration compared with a conventional helicopter provides growth capacity. “We looked at a single main rotor helicopter for FARA, but it would be minimally compliant in the early 2020s. We need to be able to stay ahead of the threat into the 2030s and 2040s,” he says. Bell is proposing a winged, single-main-rotor helicopter for FARA, while AVX Aircraft is offering a coaxial-rotor, ducted-fan compound. Boeing and Karem Aircraft have yet to unveil their concepts. “Single main rotor will not be able to keep up. It's already tapped out meeting the minimal FARA requirements. It does not have the ability to grow capability over time,” Malia says. “We didn't want to pull out all the stops to be minimally compliant when we had X2 able to carry more payload and go faster.” The Raider-X has four-blade rotors and a pusher propulsor. The coaxial rotors generate lift only on the advancing sides, eliminating retreating-blade stall and enabling higher speed. At high speed, 90% of the engine power goes to the propulsor, says Bill Fell, senior experimental test pilot. The propulsor is declutched at low speed to reduce noise. The Raider-X closely resembles the S-97 prototype, with side-by-side seating. Compared with tandem seating, this improves crew coordination and situational awareness, Malia says. “And we can do it aerodynamically because of the robust performance inherent in X2. We are not trying to get out every last ounce of drag.” Behind the cockpit is a large internal weapons bay. Internal carriage of missiles and unmanned aircraft—which the Army calls air-launched effects (ALE)—is a FARA requirement, but Malia says the cabin-like volume of Raider-X's bay provides growth space for future, larger systems. “The minimum threshold works now, but what if in 2030 there is a new ALE that can be decisive, but can't be carried?” he asks. The Raider-X is powered by a single 3,000-shp-class General Electric T901 turboshaft—government-furnished equipment to all FARA bidders. “We do not have an additional engine to increase speed,” Malia says, referring to the supplemental power unit in Bell's 360 Invictus. This augments power from the single T901 to give the single-main-rotor, tandem-seat Invictus a 185-kt. maximum speed. “We use the power available and have a solid design built around it,” he says. “The T901 provides speeds out of the chute in excess of requirements and, as it improves, we can take direct benefit. We have a growth path to additional speed and payload as the T901 power increases.” Sikorsky is using the industry-funded S-97 prototype to reduce risk for its FARA bid, conducting flight testing to validate design models and optimize the Raider-X. This includes flying new rotor blades designed to reduce drag and vibration. “We are getting exactly the results the models said,” Malia says. With two rotor systems and a propulsor, Sikorsky is paying close attention to the Raider-X's cost. “We have done a complete affordability analysis and design to cost. We are extremely confident we will come in under the cost goal,” he says. Several divisions of parent company Lockheed Martin are part of Sikorsky's FARA team, Malia says, including Aeronautics, Missiles and Fire Control and Rotary and Mission Systems. Swift Engineering will build the airframe if Sikorsky wins one of two FARA competitive prototype contracts scheduled to be awarded in March 2020. The Army flyoff is planned for 2023, with the first unit to be equipped by 2028. “There is a critical cap in vertical lift, in attack/reconnaissance, and that gap is really impactful to the Army in the 2020s, ‘30s, ‘40s, even ‘50s. So there is a need for a long-term solution,” Malia says. “The threat is projected to evolve rapidly, so we require significant capability growth on our side to stay ahead. Raider-X can provide an asymmetric advantage in the 2030s-50s.” https://aviationweek.com/defense/sikorsky-unveils-raider-x-proposal-fara-armed-scout

Pascal Kümmerling Le gouvernement finlandais a fixé un plafond de 11 milliards de dollars américains pour l'achat du futur avion de combat a annoncé mercredi le ministère de la Défense. Le plafond financier comprendra le coût d'achat de nouveaux jets, de leurs armes et de divers systèmes au sol. Le projet vise à remplacer la flotte actuelle de 64 avions de combat F/A-18C/D « Hornet » achetés aux États-Unis au début des années 90. Le ministre finlandais de la Défense, Antti Kaikkonen, a déclaré que le nombre de nouveaux avions à acheter pourrait être supérieur ou égal au niveau actuel et espérait qu'il ne serait pas inférieur. Les bases du projet La Finlande ne veut pas sacrifier sa capacité d'engagement en temps de paix et doit pouvoir compter sur une dotation lui permettant un engagement sur de longs mois en cas de situation tendue au niveau international. Pour ce faire la Force aérienne veut un minimum de 64 nouveaux avions de combat multirôle, soit la même dotation qu'actuellement. Pour la Finlande il n'est pas question de sacrifier sa capacité d'action. L'avion doit pouvoir évoluer en réseau connecté avec les systèmes de défenses au sol et le reste de l'armée. A noter, que la Finlande estime que les coûts à l'heure de vol pourraient atteindre trois fois le montant du prix d'achat sur une période de 30 ans. Cette donnée sera prise en compte pour le choix final. Les aéronefs en compétition On retrouve une nouvelle fois les grands classiques du moment, avec le Lockheed-Martin F-35 «Lightning II», le Saab JAS-39 Gripen E MS21, l'Eurofighter «Typhoon II» T3A/B Block20 et le Dassault Rafale F3-R, ainsi que le Boeing F/A-18 E/F « Advanced Super Hornet ». Essais techniques La Finlande a observé avec intérêt les essais des quatre avions effectués ce printemps dans notre pays à Payerne. Le pays procédera également à des tests techniques qui seront effectués en Finlande cet hiver. Mais avant cela, le pays enverra des demandes d'offre plus détaillées aux candidats durant l'automne. Les dernières offres seront organisées en 2020. Le gouvernement finlandais fera son choix en 2021. Le Hornet en Finlande C'est en 1992 que la Finlande décida d'acquérir 64 F/A-18 C/D «Hornet» pour remplacer les bons vieux MiG-21 et Saab J-35 «Draken». A l'époque, les Hornet finlandais ne sont pas complètement équipés, notamment en matière de guerre électronique et d'avionique, ce qui avait permis à l'époque de faire baisser le prix d'achat. Mais dès le début des années 2000, la Finlande décida d'équiper ses « Hornet » des systèmes manquants. Depuis les « Hornet » finlandais ont reçu les missiles air-air à moyenne portée de type AIM-120 AMRAAM avec un système de système de visée plus performant et de doter ceux-ci, du système de guerre électronique AN/ALQ-67. Le groupe de travail du ministère de la Défense finlandais a recommandé que la flotte de F/A-18C/D puisse entrer en retraite durant la période 2025-2030. A signaler, que la Finlande considère que le coût d'un programme d'extension de vie des « Hornet » est à la fois risqué et prohibitif. https://blogs.letemps.ch/pascal-kuemmerling/2019/10/13/helsinki-dispose-de-11-milliards-pour-son-nouvel-avion/

WASHINGTON, Oct. 15, 2019 /PRNewswire/ -- The U.S. Army recently awarded Lockheed Martin (NYSE: LMT) a $40.6 million contract to produce Modernized Turrets (M-TUR) for the AH-64E Apache helicopter, an upgrade to the Modernized Target Acquisition Designation Sight and Pilot Night Vision Sensor (M-TADS/PNVS) system with enhanced operational and performance capabilities.

Sikorsky has dialed up the autonomous flight control system on an experimental UH-60A Black Hawk to where a pilot can “set it and forget it” during long surveillance missions, another step toward flying the aircraft remotely from the cabin or from the ground without pilots on board. To date, Sikorsky has put 54.5 flight hours on its optionally piloted vehicle (OPV) flight control system, which is designed as a kit that replaces all legacy mechanical controls in existing aircraft with its MATRIX autonomous fly-by-wire controls. It has also run about 30 hours on the ground in the UH-60A, one of the oldest Black Hawks in the Army's inventory, according to chief test pilot Mark Ward. During the first of MATRIX in a Black Hawk in May, Sikorsky focused on the direct mode control scheme, which means the fly-by-wire controls should fly and respond to pilot input like a conventional UH-60 Black Hawk, Ward said. Technically, the mode is “direct stick-to-head with stability augmentation in the loop.” “Direct mode is supposed to be, more-or-less the service mode or an emergency mode, but we found the aircraft behaved quite well throughout all the speed regimes in that mode,” he said. Sikorsky briefly paused the flight test program to “fine tune” some of the pilot control augmentation modes, “so that when we go to autonomy we're going to have a very mature system that goes from full-spectrum of pilot 100 percent in the loop, to autonomy 100 percent in the loop and everywhere in between,” he said. Test pilots have since ratcheted up computer control of the aircraft and expanded the flight envelope out to 150 knots indicated airspeed. Most interestingly, the test team is beginning to increase the level of flight control augmentation beginning with “direct mode.” In “rate command attitude hold” mode, the fly-by-wire system takes over more control of the aircraft, Ward said. That mode was tested through low-speed hover maneuvers out to 150 knots. “When you put a control input, you're controlling a rate or an attitude change and when you release the control, you're capturing that attitude,” he said. From there, test pilots increased autonomous control of the aircraft to the full authority control scheme, or FACS, in which “rather than commanding a rate, you're actually commanding a parameter, such as airspeed or altitude or heading using the control stick,” Ward said. “To change from one mode to the next is simply a button push away to go from direct to rate command, up to FACS and back down,” he said. “Think of full authority as being an ultra-stable ISR platform that is going to be holding flight parameters for very long periods of time,” he said. “You kind of want to set it and forget it. You're not turning knobs on a flight director. You are actually flying the aircraft with the control stick.” “Rate command is when you kind of want to . . . throw it around a little bit, you want to do some low-and-slow or low-and-fast maneuvering where you're going from stop to stop to complete a mission.” Sikorsky uses the phrase “optimally piloted vehicle” as well as “optionally piloted vehicle” when discussing OPV and MATRIX because the ultimate goal is to develop a system that can act as an autonomous co-pilot quietly but constantly aiding human operators during specific missions. The OPV kit is tailored to the UH-60, but is retrofittable onto the Army's entire helicopter fleet and Sikorsky's commercial S-92 and S-97 rotorcraft, according to Igor Cherepinsky, the company's director of autonomy. Sometime in 2020, Sikorsky will demonstrate that the system can be remotely piloted from both inside and outside the aircraft, he said. “We will show the world this system is capable of being operated from the ground,” he said. Sikorsky continues to demonstrate MATRIX on a modified S-76B called the Sikorsky Autonomy Research Aircraft (SARA). The aircraft, which has been in test since 2013, has more than 300 hours of autonomous flight. The company announced in March that its S-92 helicopter fleet update will include the introduction of phase one MATRIX technology, which will allow for autonomous landing. The U.S. Army has plans to outfit a UH-60M with the system but is about six months behind Sikorsky's OPV test program. “Our vision is, obviously, not to replace the pilots, but to augment the pilots,” Cherepinsky said. “Once we field the technology, we never want to see another controlled flight into terrain or degraded visual environment issue accident ever happen with any of our aircraft.” https://www.verticalmag.com/news/sikorsky-ratchets-up-robotic-control-of-black-hawk-in-runup-to-pilotless-flight/

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
