Critical Review of Methods to Predict the Buffet Capability of Aircraft,

摘要

Studies on the buffet characteristics of aircraft in the transonic speed range raise considerable analytical difficulties, which have been of great concern to designers. Due to the complexity of the flow field beyond the buffet boundary, theoretical solutions to the buffet problem are impossible at the present time. Therefore researchers are attempting to develop new wind-tunnel test techniques and establish correlation factors to flight test results. The report gives a state-of-the-art of methods used in Europe to predict buffet boundaries and response. A comprehensive survey of practical techniques and analyses is made and a critical review of their respective capabilities and limits of validity is presented.
