Procedure for Determining Aerodynamic Drag and G Profile of a Missile Using Unsmoothed Position Data
Abstract
A procedure is described for determining the areodynamic drag and G profile of a missile using unsmoothed observed position data. The procedure uses numerical integration in computing trajectory data that simulates the observed data. An iterative process is used to obtain a reasonable match between the computed and observed trajectory data. The aerodynamic drag used in computing the trajectory that matches the observed data is a good estimate of the drag of the missile. The G profile is included in the computation. An example is given where the procedure was applied to a B61 Mod 0 bomb deployed in the retarded laydown mode. The results obtained with this procedure are compared to the results obtained using two different smoothing techniques.
