Keywords: flight simulation, engine simulation, noise prediction

A noise prediction simulation environment is presented that combines the simulation of aircraft trajectory, attitude, speed and thrust with a simulation of the corresponding jet-exhaust characteristics and the resulting noise characteristics. The method is demonstrated for a fighter aircraft, but it can also be applied to civil aircraft.
