The report presents an analysis procedure for predicting antiskid operational characteristics and the inter-related effects upon the aircraft and its performance. The analytical procedure is the development of mathematical equations for a comprehensive description of antiskid system components, the significantly influencing aircraft systems and the characteristics of the surface upon which the aircraft is operating. The mathematical description includes such considerations as landing gear dynamics, tire elasticity, brake torque response characteristics, antiskid electronic circuitry, brake hydraulic control system dynamics, runway surface profile and tire-to-runway friction characteristics. Both on-off and modulated antiskid systems are analyzed. Procedures for quantitative evaluation of the influencing parameters and examples of their usage are also presented. The implementation of the analytical prediction procedure by simultaneous solution of all the mathematical equations on an electronic computer is described.
