Research abstract
A HIGHLY EFFICIENT CONCEPT IS PROPOSED WHICH WILL SUBSTANTIALLY REDUCE ACOUSTIC SIGNATURES OF HELICOPTERS AND TILT ROTOR AIRCRAFT. THE CONCEPT CAN BE INCORPORATED INTO FUTURE HELICOPTER DESIGNS WITHOUT ANY OBVIOUS, WEIGHT OR PERFORMANCE PENALTIES. THE CONCEPT WILL PRODUCE REDUCTION OF SOUND RADIATION IN ALL DIRECTIONS OVER ALL FLIGHT SPEEDS WITH MINIMAL PROCESSING.
