Development of a three-dimensional, computational fluid dynamics code was studied to provide reliable, economic computations of store separation from an aircraft where the stores have plumes. The purpose of this code is to study plume ingestion and mutual aerodynamic interference between the store and the aircraft. The effort in this project is consistent with and meant to complement the on-going shuttle work at NASA Ames.Phase I provided a study of the three-dimensional static CHIMERA code to determine how best to modify it for store separation and how best to include a plume. A generic wing was chosen with a generic missile without fins. An algebraic grid generator was written for fighter wings. The codes were modified for the wing and wing-store solutions. Several wing-alone runs were made to test the accuracy of the flow solver. Issues pertinent to store separation were identified and solution theory was formulated.Potential Commercial Application:The general method may apply to the calculation of ground effects on automobile performance and transient aerodynamic effects of two or more closely moving bodies, e.g., the effects of wing tip vortices from large aircraft on other aircraft.STATUS: Project Proceded to Phase II
