V-280’s top speed of 300 knots beats current fastest military helicopter title-holder, Eurocopter’s X3. The Bell V-280 Valor is named for its 280-knot cruise speed. Through the use of composites in honeycomb sandwich configurations with large-cell carbon cores in the fuselage, wing, and tail section, the Valor boasts a 30 percent weight savings over that aircraft despite its armor.Īccording to Bell, the Valor with its crew of two and payload of 14 troops, or the equivalent weight, can fly at twice the speed of current medium-lift helicopters. Bell’s design for future military helicopter uses hybrid metal-composite construction and Large Cell Carbon Core technology for unitized wing. The flight took place at the company's Flight Research Center in Arlington, Texas after the completion of over 85 flight hours and 180 rotor-turn hours during a year of testing.ĭeveloped in partnership with Lockheed Martin, GE Aviation, Moog, IAI, TRU Simulation & Training, Astronics, Eaton, GKN Aerospace, Lord, Meggitt, and Spirit AeroSystems, the Valor is intended to be a lighter, simpler, and less expensive advance on the V-22 Osprey.

Bell's V-280 Valor tiltrotor combat aircraft lived up to its name on Wednesday as it pegged the speedometer at a true airspeed of 280 knots (322 mph, 518 km/h), or twice that of conventional rotorcraft.
