We have already presented on several occasions the FLRAA program, for Futur Long Range Assault Aircraft, intended to replace the UH-60 Black Hawk maneuver helicopters of the US Army, and integrated into the Futur Vertical Lift hat program, itself one of the pillars. of the great program "Big 6". If we knew that the expected performance, especially in terms of speed, clearly exceeded the current performance of rotary aircrafts, the US military authorities have now detailed their ambitions more precisely, and the least that can be said is that the term "ambition" is not usurped!
Today, a maneuver helicopter, whose primary function is the transport of armed soldiers for airborne assault missions, operate between 260 and 280 km / h, with a top speed rarely exceeding 300 km / h. The new US Army aircraft will have to sustain a cruising speed of 280 knots, or almost 520 km / h. Note that this speed is higher than that of many transport planes equipped with turboprop engines, such as the CN-235 whose cruising speed is 250 knots (450 km / h).[Armelse]
