Abstract
A flap-type, two-dimensional nozzle for use with thrust creating vehicles which operate at both subsonic and supersonic speeds includes a rectangular exhaust with a cooperating primary flap and rotatable flap at the top and bottom thereof, the top and bottom flap systems have the primary flaps controlled collectively while the rotatable flaps rearwardly thereof can be controlled collectively or individually to achieve their desired objective. The primary flaps of the flap systems move between a position of minimum throat area and maximum throat area while the rotatable flaps move between a plurality of symmetrical positions which provide for forward thrust and reverse thrust and a plurality of differential positions which provide for thrust vectoring and modulated thrust.
