Mathematical Models for Missiles

Abstract

This paper describes the use of a large analogue computer, supplemented by digital computations, to study the effects of high-incidence aerodynamic non-linearities and cross-couplings on the performance of a hypothetical cruciform missile. Aerodynamics data, obtained from wind-tunnel tests of a suitable model, were simulated in detail, and linear aerodynamic characteristics were subsequently substituted and simulated for purposes of, comparison. The effects of the aerodynamics on response and on homing performance against targets turning at a constant rate are displayed as graphs, and the importance of accurately simulating the aerodynamics is demonstrated. Techniques which proved useful in simulation are described, and the accuracy and limitations of the analogue method are indicated by comparisons of the simulator results with others obtained digitally.
