Grid based approach to store separation

Abstract

Abstract : Since early in the development of aerodynamic computational tools, when complex aircraft configurations could for the first time be accurately represented, the Holy Grail of the CFD community became predicting the trajectory of a store from an aircraft. However, the participants could never agree on either what would constitute a successful prediction, or what computational approach should be used. Many claimed that store separation was an unsteady phenomenon, and that the solutions would have to be done in a time dependent manner (this despite the multitude of evidence to the Contrary, where quasi-steady wind tunnel simulations in almost all cases have shown excellent agreement with the flight test results).
