DEFIANT Expands FVL Flight Envelope

The Sikorsky-Boeing team continues to make great progress as we advance DEFIANT’s rigorous flight test program. With every flight, as we continue to increase DEFIANT’s speed, angle of bank and rate of climb, we are gathering important data, expanding our speed and maneuverability envelope and validating our modeling and simulation tools. On Oct. 12, with only about two-thirds prop torque and engine power, DEFIANT achieved 211 knots straight and level and 232 knots in a descent. We are excited about the res
