Abstract:

The response of an aircraft as a function of time on encountering an isolated ramp gust is derived from its response to a unit step gust. Two FORTRAN programs are described which treat separately straight ramp and smooth ramp one-minus-cosine gust profiles. The critical gust length causing maximum dynamic response is determined and responses to simple gust patterns pairs are investigated. Author
