Abstract:

The numerical integration technique to utilized in the reduction and analysis of data gathered in the USAF Aeroballistic Research Facility located at Eglin Air Force Base is described. The method of Chapman and Kirk has been developed into a system of digital computer programs which may be easily and routinely used in the analysis of data derived from spark range firing. The equations of motion for a missileprojectile in free-flight are derived in this report utilizing the six degrees of freedom. The parametric equations, philosophy, and methods of implementation are also derived and discussed. Brief descriptions of the computer program involved are also given.
