The Response of an Airplane to Random Atmospheric Disturbances

Abstract

The local velocity fluctuations acting on an airplane flying through atmospheric turbulence are functions of time defined only in a statistical sense and, hence, constitute a stochastic or random process. Consequently, the responses of the airplane, whether they are motions (linear or angular displacement, velocities, or accelerations), forces (lift, pitching moment, bending moment, and so on), stresses, or any other phenomena determined by the turbulence, can also be known as functions of time in only a statistical sense. This paper is concerned with the statistical characteristics of those responses which have a bearing on the loads and stresses experienced by the airplane; although other problems such as those relating to passenger comfort or to the stability of the airplane as a gun platform can be treated in the same manner, they will not be considered here.
