SB>1 DEFIANT™ Moves Forward for Future Vertical Lift
Design Phase will Reduce Risk for Army’s Future Long Range Assault Aircraft Program
The U.S. Army announced that the Sikorsky-Boeing team has been selected to move forward in the Future Long-Range Assault Aircraft’s Competitive Demonstration and Risk Reduction Program (CD&RR) program.
Sikorsky is partnered with Boeing on the SB>1 DEFIANT program in order to meet the demands of the Army’s future vertical lift mission. DEFIANT is highly maneuverable and will extend the warfighter’s capabilities on the modern battlefield – and fits in the same footprint as a Black Hawk.
DEFIANT builds on Sikorsky’s foundational X2 Technology which integrates coaxial rotors, fly-by-wire flight controls and a propulsion system to redefine the attributes and abilities of a typical helicopter.
SB>1 DEFIANT™ in action
"When DEFIANT flies, it's the result of so many hours of work to get there. We don't get surprised in flight test.” ~ Sikorsky President Dan Schultz
Sikorsky and Boeing have purposely carried out a rigorous flight test plan with DEFIANT. The flight test program includes thousands of hours in integrated test labs, component development and the propulsion system test bed.
This approach has allowed the team to strategically expand the envelope in flight test and prove out each element of the technology. Each hour of test, even on the ground, helps to inform the next.
“When we’re flying at 130 knots in this machine, we’re using less than 20 percent of the propeller power and less than 30 percent of the engine power, so expect a lot more.” ~ Sikorsky test pilot Bill Fell
DEFIANT recently flew in a demonstration for Senator Tammy Duckworth and Secretary of the Army Ryan McCarthy. During that flight DEFIANT hit 140 knots and 45-degree angle-of-bank turns. The aircraft will continue to expand the envelope in flight test throughout the rest of the year.
The SB>1 DEFIANT team is prepared to provide an affordable and sustainable solution to give the Army mission advantage on the highly contested battlefield of the future.
