EGLIN Store Separation
Introduction
This problem is a CFD simulation of a wind tunnel experiment conducted at Eglin AFB, USAF to analyze the effects of aircraft interfering with each other during the separation of external attachments. Validate the flow analysis around the moving object by comparing the trajectory and attitude angle of the external mount and the pressure coefficient.
