DENVER — Since the Army canceled plans to develop a Future Attack Reconnaissance Aircraft earlier this year, the two anticipated competitors have both moved to make use of their work on the program.
The service is closing out its FARA effort at the end of fiscal 2024. Two teams — Textron’s Bell and Lockheed Martin’s Sikorsky — were competitively building prototypes expected to fly this year.
Jeff Schloesser, Bell’s executive vice president of strategic pursuits, told Defense News at the Army Aviation Association of America’s conference here earlier this month that the company had already installed the Army’s Improved Turbine Engine Program, or ITEP, engine in its 360 Invictus aircraft prototype when it got word of the cancellation.
Sikorsky was in a similar boat, according to Paul Lemmo, the company’s president. Shortly after hearing about the FARA cancellation, the company began proposing using the ITEP engine in its FARA prototype, known as Raider X, to test it ahead of its installation into the UH-60 Black Hawk helicopter, which the company also makes.
The Army plans to replace all Black Hawk and AH-64 Apache attack helicopter engines with ITEP engines in the coming years, but the program has been delayed due to technical issues as well as supply chain problems during the COVID-19 pandemic.
After the Army agreed to the plan, Sikorsky earlier this month used the ITEP engine in its FARA prototype at its West Palm Beach, Florida, test center, Lemmo said.
“It performed well,” he said. “This is the first time it’s under a full load in a real aircraft turning rotors. We collected that data at low speed, we’re analyzing it and the Army’s authorized us to now run up to full speed on the ground to collect more data.”
ITEP will go into a Black Hawk for tests later this year, he noted.
Schloesser said the ITEP engine in Bell’s possession has already been sent back to General Electric Aerospace, the engine’s manufacturer.
The termination of the FARA program, he added, means the company has redirected engineers and specialists to the Future Long-Range Assault Aircraft program.
The Army is pursuing the FLRAA aircraft, expected to be fielded by 2031, to operate across long-distances more quickly. The Army in late 2022 chose Bell to build an aircraft based on its V-280 Valor technology demonstrator, and the program will soon enter the engineering and manufacturing development phase.
Bell’s manpower shift over to the FLRAA program is allowing the effort to move “a little bit faster than we anticipated,” Schloesser said.
He also said work on a Modular Open System Architecture, or MOSA, in the FARA program will benefit the FLRAA program.
Sikorsky, meanwhile, will seek a home for the X2 coaxial technology it was refining across both the Defiant platform, its failed candidate for the FLRAA competition, and Raider X.
The company is pursuing a next-generation helicopter for Italy and the NATO Next-Generation Rotorcraft Capability, according to Lemmo.
“There’s a few other countries I won’t name that we are involved early in discussions about X2, so we’re going to continue to pursue that and see where that goes,” he said.
