Abstract:

The development of a digital computer program to extract aerodynamic coefficients from dynamic data from six-degree-of-freedom systems is presented. The derivation of a system mathematical model is discussed in detail. Results, and associated problems, of extracting coefficients from one, two, three and six-degree-of-freedom systems data are also presented.
