The Demon is a UAV designed by BAE Systems as part of its FLAVIIR project. It has a novel aerodynamic control system which uses engine exhaust and bleed air to provide the aerodynamic forces usually provided by flaps ailerons and elevators. It has been called the world's first flapless plane. It first flew from Walney Island off the coast of Cumbria UK on 17 September 2010.
