Aeroballistic Range Data Analysis for Nonsymmetric Configurations

Abstract

A model (equations of motion) has been developed which is capable of computing the six-degree-of-freedom trajectory of a nonsymmetric missile. The forces and moments considered to be acting on the missile are described in a body-fixed coordinate system. The model has been incorporated in a data correlation technique using differential corrections and least-squares theory. A system of five computer programs was developed for complete analysis of ballistic spark range data on a nonsymmetric missile. These are to be used for analysis of data gathered in the USAF Aeroballistic Research Facility, Eglin AFB. The model and data correlation technique were used to analyze ballistic spark range data on two elliptic cones. Individual and simultaneous reductions resulted in probable errors of fit approximately equal to the accuracy of the data. The results of these reductions are presented.
