Flight of Flexible Aircraft in Turbulence. State-of-the-Art in the Description and Modelling of Atmospheric Turbulence. Addendum

摘要

Large-scale use of flight recorders by commercial airlines, coupled with the enhanced quality of results offered by modern computer-based reduction processes makes it possible to broaden knowledge of the phenomenon of atmospheric turbulence. At the same time, new methods for predicting the response of flexible aircraft to turbulence are being proposed, and novel gust alleviation systems are being designed and tested. The Structures and Materials Panel held two Workshops on this topic. This volume records the presentations made at the second workshop to discuss methods of analysis and regulations. Papers include: Current and proposed gust criteria and analysis methods - An FAA overview; Flight test equipment for the on-board measurement of wind and turbulence; Matching P.S.D. - design loads; Summary of methods for establishing airframe design loads from continuous gust design criteria; Comparison of the influence of different gust models on structural design; Measured and predicted responses of the NORD 260 aircraft to low altitude atmospheric turbulence; Review of measured gust responses in the light of modern analysis methods. Keywords: Flight characteristics; Data reduction airborne accelerometers. (EDC)
