FVL: Army Picks Bell & Sikorsky For FARA Scout

The Bell 360 Invictus and the Sikorsky Raider-X will vie for the final contract to build FARA, with rival prototypes in flight by 2023. Bell and Sikorsky (with Boeing) are also facing off for the FLRAA transport.
By SYDNEY J. FREEDBERG JR

WASHINGTON: The Army has now narrowed its future aircraft choices to Sikorsky vs. Bell.

This afternoon, the service announced that it had picked Sikorsky and Bell to build competing prototypes for Future Attack Reconnaissance Aircraft (FARA), a high-speed optionally manned scout to replace the retired Bell OH-58 Kiowa. Just eight days ago, it picked the same two firms – plus aerospace giant Boeing, acting as Sikorsky's de facto junior partner – to compete for the Future Long-Range Assault Aircraft (FLRAA), which will replace the Sikorsky's UH-60 Black Hawk as the military's aerial workhorse for everything from Ranger raids to medevac.

The FLRAA transport decision was no surprise. The Army picked the two teams it had been funding for years to develop prototypes, the Bell V-280 Valor tiltrotor and the Sikorsky-Boeing SB>1 Defiant.

There was more uncertainty over the FARA scout, because the service had given five companies Other Transaction Authority contracts to develop designs. Of those five, only Sikorsky had built and flight-tested an actual aircraft, the S-97 Raider, of which its Raider-X design is basically a super-sized version. Sikorsky and Bell now get to build FARA prototypes, while AVX, Boeing, and Karem have been cut.

While AVX and Karem are design houses that have never built an actual aircraft, Boeing is a major aerospace player for which this is just the latest in a series of blows.

Sikorsky and Bell have taken starkly different approaches to Future Vertical Lift. For both the FARA scout and the FLRAA transport, Sikorsky is offering its signature compound helicopters, descended from its record-breaking X2, that use a combination of ultra-rigid coaxial rotors and a pusher propeller to overcome the aerodynamic limits that cap the speed and range of traditional helicopters. No compound helicopter has ever entered mass production, but Sikorsky has built and flown two S-97 prototypes and, with Boeing, the much larger SB>1 Defiant: Raider-X will fall between the S-97 and SB>1 in size.

Bell's marquee technology is the tiltrotor, most famously the widely used V-22 Osprey, using two massive rotors that tilt forward like a propeller for level flight and upwards like a helicopter for vertical takeoff and landing. It's a next-gen tiltrotor, the V-280 Valor, that Bell is flying for FLRAA.

But Bell couldn't scale down their tiltrotor design – whose side-by-side rotors inevitably make for a wide aircraft – enough for the Army's FARA scout, which is meant to fly down city streets in urban warzones. So instead, their Bell 360 Invictus is, in essence, a streamlined conventional helicopter with wings: It has a single main rotor and a tail rotor, just like the old Kiowa, but it adds winglets to help with lift for high-speed fleet.

Sikorsky argues their compound helicopter configuration is inherently much more efficient, pointing out that Bell's design requires more horsepower to achieve the Army's required speeds. Bell argues their time-tested single-main-rotor configuration will be less risky to develop, cheaper to buy, and easier to maintain.

They each have three years to prove their case to the Army.

    UK: Millions awarded to defence firms leading fight for modern battlefield

    Defence firms with cutting-edge ideas ranging from laser radars to Artificial Intelligence have been awarded over £10 million after being named winners of the MOD and Defence Growth Partnership (DGP) Innovation Challenge by Defence Minister Stuart Andrew. The winners provided innovative solutions to key strategic future demands for UK defence in autonomy and big data. The companies and their ground-breaking technologies will receive combined investment and support worth over £4 million from the MOD and £6 million from industry partners to see their full development. The winning solutions announced at the Institute of Engineering and Technology today are: Close Air Solutions with Project Hyper Real Immersion QinetiQ's Software Defined Multifunction LIDAR Horiba Mira's UGV Localisation and Perception using Deep Learning Neural Networks Polaris' Ants on Deck Defence Minister Stuart Andrew said: From shrewd navigation software, A.I. driven autonomous vehicles, laser radar to mixed reality training systems, today's winners are a clear demonstration of industry rising to meet the complex challenges of modern warfare. The MOD, working with commercial partners, will see these pioneering technologies go from the drawing board to the battlefield. Training is at the core of military capabilities and Project Hyper Real Immersion is designed to provide cutting-edge realistic air combat training. This revolutionary technology from Close Air Solutions aims to enable fully networked live training exercises with NATO and Coalition partners. This will reduce costs and increase safety for service personnel. QinetiQ's Software Defined Multifunction LIDAR (laser radar) system will provide a range of high-tech capabilities including 3D imaging, optical communication and covert targeting. Conventional 3D mapping can discover a vehicle under camouflage netting but LIDAR could also determine whether the engine is on and the type of vehicle using vibration sensors. The system could be adopted onto small satellites and unmanned and manned platforms Horiba Mira is developing a super-intelligent navigation system which uses Artificial Intelligence algorithms to identify landmarks around a military vehicle to provide a greater situational awareness. This technology will be key in developing the effective operation of unmanned autonomous vehicles in dangerous areas which will remove soldiers from dangerous situations and task them to more valuable roles. This is a crucial aim of the Last Mile logistics that UK armed forces are developing. Continuing with the autonomy theme, Polaris are developing a pioneering software system that autonomously generates the best routes for Unmanned Surface Vehicles (USVs). AntsOnDeck increases fuel efficiency which allows extended operations, provides real-time awareness of conditions and environment and can be extended to platforms across the air, land and sea domains. Co-chair of the Defence Growth Partnership, Allan Cook CBE, said: The innovative solutions developed by our own defence companies over the course of the Innovation Challenge is amazing. Using autonomy and big data these winning companies have found unique solutions to the ongoing challenges we face in the defence sector. The winners of the DGP's Innovation Challenge Final Phase have proven that their products are fundamentally important to the growth and prosperity of their companies. This final funding for the winners will enable them to complete their development and ultimately provide essential solutions in a dynamic, international and competitive market. Their success will benefit the defence sector in the UK and help us win more business in export markets. The Defence and Security Accelerator, in tandem with the Defence Solutions Centre, established the competition in 2012 to explore and develop solutions to ensure the UK armed forces stay ahead of adversaries by finding more efficient methods of communication, logistics, protection, intelligence and training. The initial investment of £10 million for the competition has been matched pound for pound with industry partners and since then, the competition has received an additional £4 million. This is part of the wider £800 million Defence Innovation Fund. Today's event brought together leading industry and military figures from the defence equipment community. This joint approach aims to create high quality UK jobs, boost defence exports and encourage collaboration between large industry, SMEs and academia. https://www.gov.uk/government/news/millions-awarded-to-defence-firms-leading-fight-for-modern-battlefield
