Nonlinear Six Degree-of-Freedom Ballistic Aerial Target Simulation Model. Volume 1. Theoretical Development

摘要

Six degree-of-freedom, rigid body equations of motion are described suitable for modeling the dynamic characteristics of multistaged, free-flight, ballistic rockets such as the DRES developed aerial targets CRV7/BATS and ROBOT-9. These equations of motion form the core of a FORTRAN simulation software package called BALSIM. This package allows for modeling of vehicle thrust and structural symmetries, time-varying mass and inertia characteristics, variable wind conditions, nonstandard atmospheric conditions, stage failures, and different rocket motor types. The BALSIM package has been written in IBM FORTRAN IV and has been tested on the IBM 3033 computer with the H-extended compiler. It is currently being adapted for use with the VAX11/780 and Honeywell DPS-8/70C computers. (Author)
