Sikorsky, Boeing selected to build Technology Demonstrator for future vertical lift

Sikorsky Aircraft and Boeing have been selected to build a helicopter for the U.S. Army’s Joint Multi-Role Technology Demonstrator Phase 1 program (JMR TD), paving the way for the next generation of vertical lift aircraft. The U.S. Army Aviation Technology Directorate (AATD) selected the Sikorsky-Boeing team to continue the development of the SB>1 Defiant, a medium-lift helicopter configured to Sikorsky’s X2 coaxial design, through flight testing. First flight for the program is expected in 2017. The Defiant aircraft will feature counter-rotating rigid main rotor blades for vertical and forward flight, a pusher propeller for high-speed acceleration and deceleration and an advanced fly-by-wire flight control system.
