Proprotor blades stop and fold back and propulsion transitions from turboshaft to turbofan to accelerate the X-76 to speeds ...
The Defense Advanced Research Projects Agency has advanced development of the X-76 experimental aircraft under its SPeed and Runway INdependent Technologies, or SPRINT, program. DARPA said Monday ...
Planned to fly in 2028, the X-76 will explore technologies for fast-flying runway-independent aircraft with folding rotors, crewed and uncrewed.
DARPA has assigned the designation X-76 to the Speed and Runway Independent Technologies (SPRINT) project, a Bell proof-of-concept technology demonstrator for a high-speed tiltrotor. The DARPA ...
Bell's X-76 aircraft achieves 517 mph cruise speeds with vertical takeoff capability, eliminating runway dependencies through innovative folding rotors.
