 | The Supersonic Transport Noise Reduction Technology Program, sponsored by the Federal Aviation Administration, was conducted as a follow-on effort after cancellation of the SST Program to finalize selected noise technology areas and summarize results of the SST Program. Using initial effects of the SST Program, as summarized in Phase I of The Supersonic Transport Noise Reduction Technology Program, the Phase II contract was issued to the General Electric Company (and ... |

| Both compressor and turbine noise were studied in the turbomachinery noise reduction areas. A 3-stage low pressure compressor with variable-flap inlet guide vanes was tested at General Electric's outdoor test site. A hybrid inlet, which employs airflow accereration supression in combination with wall acoustic treatment, was investigated as the suppression device for all three noise monitoring point operating conditions. The effect of auxiliary inlets on noise leakage and suppression was ... |

 | A development program for a commercial supersonic aircraft and engines was sponsored by the Federal Aviation Administration during a five-year period from 1966 through 1971. The unique propulsion system, an afterburning turbojet, required acoustic suppression techniques to reduce its noise levels to those federally regulated for subsonic aircraft. An acoustic suppression research program was conducted by the General Electric Company to develop technology applicable to prototype and commercial supersonic engines. ... |
