Abstract:

Experience has shown that the aircraft gust sensitivity index A, defined as the root mean square RMS acceleration response per unit of RMS gust velocity does not provide a consistent measure of aircraft ride quality. Ride quality is also influenced by variation in the frequency spectrum of the vibration environment and time of exposure. A ride quality evaluation technique is presented which includes consideration of frequency effects on human discomfort, exposure time, and variation of the vibration environment during a mission. This technique can be used to evaluate ride quality of existing aircraft as well as to provide ride quality criteria for new aircraft designs. It can be applied to military as well as commercial aircraft. Author
