Title: Review of Aircraft Noise, Rotor Noise, Jet Noise, and Sonic Boom
Abstract: This paper discusses the papers presented in the two sessions on aircraft noise at Purdue. The first session on Aircraft and Rotor Noise included invited papers on airport noise (MCK. ELDRED) and rotor noise (REETHOF) and several contributed papers on the prediction of rotor noise both from propellors and from compressors. Two papers also discussed the problem of propagation and absorption of compressor noise in ducts. The second session on Jet Noise and Sonic Boom included an invited paper on response to jet noise (Clarkson) and several contributed papers on supersonic jet noise and on rocket noise. Three papers also discussed the prediction of sonic boom overpressures.
