Revised Fold-Away Rotor Aircraft Concepts Emerge From Special
Operations X-Plane Program
Fast-flying runway-independent aircraft with folding rotors, crewed and uncrewed, could perform more than just special operations missions.
Bell has released a rendering showing updated design concepts for vertical takeoff and landing-capable crewed and uncrewed aircraft that feature proprotors that fold away during cruise. The company is working toward building a flying demonstrator using this technology as part of a program intended to present options for a potential future high-speed, runway-independent special operations airlifter.
The new rendering accompanied an announcement from Bell yesterday about the completion of wind tunnel testing in support of its work under the U.S. Defense Advanced Research Projects Agency’s (DARPA) Speed and Runway Independent Technology (SPRINT) program. Bell is one of two companies currently working on designs as part of Phase 1B of SPRINT, the other being Aurora Flight Sciences, a Boeing subsidiary. Aurora’s SPRINT concept uses multiple internally mounted lift fans for vertical flight, as you can read more about here.
