Title: X-31 in flight Movie Number: X-31 Movie Date: 1990s Keywords: X-31 Format: 320x240 MPEG (3,049 KBytes)
Streaming: Description: The X-31 EFM (Enhanced Fighter Maneuverability) was designed to explore concepts and technologies for an extremely maneuverable fighter aircraft. Particular goals pertained to controllable flight at high angles of attack and the slow-speed environment. The X-31's re-programmable digital flight control system was also used to simulate the flying qualities of a tailless or semi-tailless aircraft.
The following video clips demonstrate the remarkable agility of the X-31. Maneuvers like the Herbst and Mongoose were entirely new, and unique to the X-31. These "post-stall" maneuvers are flown at angles of attack that would put a conventional airplane in a stalled condition, and beyond its aerodynamic limits. The clips run from about 18 to 45 seconds in length.
