Abstract : The Conference Proceedings contain 26 papers presented at the Propulsion and Energetics Panel 78B Specialists' Meeting on Combat Aircraft Noise which was held 23rd-25th October 1991 in Bonn, Germany. Noise emission from combat aircraft at low altitude, high-speed training missions over populated areas has led to massive complaints. The purpose of the Meeting was to offer a forum for specialists to discuss the latest state of the technology concerned and-if possible-to find solutions for overcoming the problems. The Specialists' Meeting was composed of the following sessions: User's Demand, Experience of Noise Effects (11); Mechanisms of Noise Generation (5); Noise Measurements, Predictions Methods (6); Noise Reduction (4). Questions and answers of the discussions follow each paper in the Proceedings. As a result, there were numerous possibilities in discussion for moderate noise reductions, while for significant noise reductions the prospects arc unclear.
