Abstract
The sound suppressor hereof significantly reduces the operational noise of jet engines, particularly on takeoff and approach of jet aircraft. The system hereof is simple, effective, and relatively low in cost. It adds relatively little weight to the engine assembly, and absorbs negligible power. The suppressor comprises convolutions of sheet metal that surround the exhaust nozzle, and direct cool air to the outer periphery of the engine exhaust gases. The result is a reduction of jet engine noise sufficient to meet the Federal Air Regulations Standards as currently established by the FAA. The suppressor is particularly advantageous for business-type executive jet aircraft.
