TECHNOLOGY TRANSFER OPPORTUNITY: Aircraft Active Pylon Noise Control System: LAR-17833-1&2

NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed new type of aircraft pylon design for noise control. A pylon connects the engine to the airframe of an aircraft. This design uses air passing through the pylon to actively disrupt the jet engine exhaust stream after it exits the engine, disrupting and redistributing the axial and azimuthal distributed sources of jet noise from the aircraft. For use on aircraft, the air intake would be on the pylon at an aerodynamically advantageous location. The delivery system would consist of pipes, a pump or pressure regulator and a plenum chamber. The air is piped through the internal pylon structure in pipes by a pump and to the plenum chamber. The injection site for the most common embodiments would be the shelf of the pylon (adjacent to the core nozzle flow) and the trailing edge of the pylon. The objective of the injection is to alter the trajectory of the core nozzle flow thereby impacting how the core and fan streams mix and the overall trajectory of the core and fan streams together. The injection site on the trailing edge has the objective of minimizing the wake of the pylon by injecting higher pressure and velocity air through the active aircraft pylon trailing edge injector. At cruise conditions, injection from the pylon trailing edge can also reduce the drag contribution of the pylon to the total aircraft drag. NASA is seeking to license this technology commercially in the United States. US Patent 9,022,311.
