Abstract : A description is given of a computer program, AERO 1, which computes a two degree of freedom, point mass trajectory. A sketch is given of the form of the analytics with a thorough description of the input. The program solves the one-dimensional equation of spin independently of the point mass trajectory, except that the dynamic pressure computed by the point mass solution for any instant of time is a parameter of the spin problem. This spin is used to compute the classical ballistic stability criteria, if desired. A description and proof of a technique for exactly simulating the effects of constant crosswind and/or range wind is appended. (Author)
