  • A scale model of the Sikorsky-Boeing SB>1 DEFIANT™ undergoes testing at the AEDC National Full-Scale Aerodynamics Complex at Moffett Field in Mountain View, California. The goal of the wind tunnel test was to validate the aerodynamic performance and flight mechanics of Sikorsky’s X2 Technology™ aircraft. These configurations, which are being utilized on the SB>1 DEFIANT™, include a lift-offset coaxial rotor system, composite fuselage and rear-mounted pusher propulsor that provides increased speed.
