A novel UAV has successfully demonstrated 'flapless flight' in the UK.
: "A British unmanned plane that uses jets of air to fly instead of conventional ‘flaps’ has made aviation history.
The experimental unmanned air vehicle (UAV), called DEMON, uses blown jets of air to control the plane’s movement in flight rather than conventional mechanical elevators and ailerons.
Experts say this will make it much easier to maintain as there are far fewer moving parts and gives the aircraft a more stealthy profile.
DEMON made its historic flight at Walney Island in Cumbria on Friday 17th September and was developed by Cranfield University with BAE Systems and nine other UK universities.
DEMON’s trial flights were the first ‘flapless flights’ ever to be authorised by the UK Civil Aviation Authority."
