Specifically developed by Bell and Lockheed Martin for the Army’s Future Lengthy-Vary Assault Plane (FLRAA) program to switch the UH-60 Black Hawk, the Bell V-280 Valor is the one Future Vertical Raise weapons system with flight-proven agility, velocity, vary, endurance, and total efficiency. It additionally provides advantages of diminished threat and long-term price from a confirmed tiltrotor platform.
The design of V-280 is derived from the UH-60 Black Hawk medium carry helicopter with main needed modifications. Whereas the V-280 has a barely broader footprint than the Black Hawk, additionally it is greater than 20% shorter, because of the absence of uncovered rotors on the main and trailing edges of the footprint. This footprint, which is exclusive to the V-280 format, permits for extra touchdown zone flexibility and elevated personnel security in every single place across the plane. Actions out and in of the touchdown zone don’t require any clutching or de-clutching mechanisms of refined propulsors with routine tilting of the proprotors. The fuselage, nevertheless, resembles that of the Black Hawk. When touchdown, the wing is greater than 7 toes above the bottom, permitting personnel to readily exit by means of two 6-foot-wide facet doorways and door gunners to have huge fields of fireside.
By way of engine, the V-280 is totally completely different if in comparison with the sooner Bell’s tiltrotor member of the family, V-22 Osprey. It’s powered by the Common Electrical T64, a free-turbine turboshaft engine, though the actual engine for the mannequin efficiency specification was unclear on the time. The V-280 Valor’s engines will stay static because the rotors and drive shafts tilt. Within the case of engine failure, a driveshaft runs by means of the straight wing, permitting each prop rotors to be operated by a single engine.
