Computational Time-Accurate Body Movement: Methodology, Validation, and Application

Abstract

A computational fluid dynamics (CFD) procedure for computing time-accurate body motion has been developed. The procedure can be used for bodies usmg a predefined motion, or for body motion resulting from loads. The chimera moving overset-mesh methodology is used in either case. The procedure is validated by comparing predictions of a pitching airfoil and a generic store trajectory to measured data. The procedure is then applied to a multiple body launch from a simulated Triple Ejection Rack (TER) and used to estimate the effect of mutual interference on a trajectory.
