An Analytical Theory of Landing-Shock Effects on an Airplane Considered as an Elastic Body

Abstract

An analytical method of determining the accelerations at any point P (x, y, z) of an airplane during landing is given. The method is applicable to any type airplane with either tricycle or conventional landing gear. The shock-strut forces are determined by a method previously published. A criterion for the mechanism of a broken spar is sought. Calculations are carried out for no particular airplane, but representative values of parameters for four-engined transports are employed.
