Abstract : This report describes a computer program which gives gyroscopic and dynamic stability factors as a function of range by combining two existing programs, Spinner and TRAJE. The program generates air-to-air, air-to-ground, and ground-to-ground trajectories. Inputs to the program are the aerodynamic coefficients obtained from Spinner computer program, projectile weight and cross sectional area, projectile muzzle velocity, vehicle velocity, and initial angle of fire. Specific information provided includes time, velocity, spin, gyroscopic and dynamic stability factors, and altitude versus range for air-to-ground, air-to-air, and ground-to-ground trajectories. The air-to-ground and air-to-air trajectories include fixed wing and helicopter launchings.
