Accuracy and Dispersion of Unguided, Air-Launched Rockets

Abstract

Simplified non-dimensional equations of motion are derived. From these, 288 rocket trajectories are calculated, based upon a variety of choices for aerodynamic, inertial, and propulsive properties. The analysis includes off-axis thrust and response resulting from initial conditions of yaw angle and yaw rate. The most important results are presented in tables and graphs. Application of the results to calculation of dispersion is illustrated in an interpretation of the results. A conclusion reached is that high static stability is not necessary for useful accuracy.
