摘要：

A computational fluid dynamic technique is demonstrated for a time-accurate store separation event at transonic speeds. An overlapping grid approach is used coupled with an implicit Euler flow solver with a flux-difference split scheme based on Roe's approximate Riemann solver and a six-degree-of-freedom trajectory code. All major trends of the trajectory are captured and surface pressure distributions are predicted. Three sources of error are identified and discussed.
