The goal of relaxed fidelity computational fluid dynamics (CFD) methods is to provide a store separation analysis capability that lies between the accuracy-productivity characteristics of influence function methods and time-accurate CFD methods. Two methods are presented in this paper, both of which provide significant accuracy improvements over influence function methods while providing rapid enough turn around times to support parameter and design studies. The first technique discussed is the Minimized ...
The analysis of store separation by computational fluid dynamics (CFD) techniques holds great promise for reducing aircraft-store certification testing. The primary concern with CFD application is the question of accuracy. This question of how much confidence should be placed on CFD generated loads data and trajectories is addressed using an uncertainty analysis technique. The process requires a formalized approach to evaluating the uncertainty associated with CFD produced loads data. This ...
