Loading conditions of tailed aircraft in longitudinal manoeuvres

Abstract

An analysis of aircraft response and loading conditions in symmetrical manoeuvres is presented with a particular recognition of the designer's needs. The analysis is based on the theory of aircraft response to elevator induced longitudinal manoeuvres. Basic response functions have been derived for the chosen, exponential type of elevator motion, and from these, general expressions have been obtained for various derived response quantities, such as tailplane loads, elevator hinge moments, normal accelerations at the tail, etc. A computational method which reduces the calculations to a routine is given in Appendix B. The method allows the evaluation of.the complete time histories of response quantities or, alternatively their significant maxima. The simplifying assumptions underlying the analysis are critically reviewed and possible limitations of the method are discussed.
