The ailerons on an airplane are hinged to the wing.
The ailerons are movable sections along the rear edges of the wings.
But, in addition to ailerons, the wing is fitted with what the project's engineers refer to as fluidic controls.
That approach was quickly abandoned, though, in favour of ailerons-hinged moving parts that provide more subtle control and place less stress on the structure.
The experimental unmanned air vehicle, called DEMON, uses blown jets of air to control the plane's movement in flight rather than conventional mechanical elevators and ailerons.
Hand pressure on the side stick controller sends electrical signals to actuators of flight control surfaces such as ailerons and rudder.
