Follow-on CRW versions could evolve into larger, piloted vehicles capable of conducting specialized missions, including reconnaissance, armed escort, urban operations, tactical air support, communications/data relay and resupply. With such flexibility, operations could originate from small-deck ships or forward bases.
"We're proud to add the X-50A designation to the CRW and our long history of experimental vehicle development at Boeing," said George Muellner, president of Boeing Phantom Works, which originally conceived the CRW and produced two prototype demonstrators. "The X-50A is another example of the kind of innovative, affordable solution that we provide to meet the future needs of our customers."
Steve Bass, X-50 program manager, said the concept is moving closer to reality and that rigorous testing is already under way.
"At our Phantom Works facility in Mesa, Ariz., Ship No. 1 is currently undergoing testing in the hover pit, and Ship No. 2 is nearly completed," said Bass. "This momentum places us on track for a first flight of the X-50A later this year."
Also known as "Dragonfly," the unmanned X-50A CRW has a length of 17.7 feet and is 6.5 feet high. The rotor blades have a diameter of 12 feet. Powered by a conventional turbofan engine, the X- 50A will utilize diverter valves to direct thrust to the rotor blade tips (for helicopter mode), or aft to the jet nozzle (for fixed wing mode). Dual bleed thrust will be used during transition.
By directing thrust through the rotor tips, the CRW concept eliminates the need for a heavy and complex mechanical drive train, transmission and anti-torque system. The CRW will be much lighter and simpler than traditional rotorcraft and will therefore be much cheaper to operate and support. |
