THE UANALOGUE COMPUTERS IN SOLVING PROBLEMS OF FLIGHT MECHANICS

Abstract

The equations of motion are established for an aircraft which has a rigid structure, taking into account additional relationships introduced into the standard equations as a result of operational conditions. The bases for calculating the general equations of motion for an aircraft with a non-rigid structure are discussed. The characteristics of the motion defined by these equations are easily studied by means of analog calculations. The principles of analog calculation and the application of such calculations to the solution of certain problems relating to the mechanics of an aircraft are presented. A number of questions concerned with the following are discussed in turn: the motion of aircraft with a rigid structure; the behavior of aircraft with a non- rigid structure; the response of air craft fitted with an automatic pilot; the calculation of landing trajectories. The automatic holding of an approach trajectory is illustrated. It is shown how analog calculations make it possible to study in detail the action of numerous parameters, and to choose, from among possible solutions, those which are worth adopting.
