An Influence Function Method for Predicting Store Aerodynamic Characteristics during Weapon Separation,
Abstract
A method has been developed for predicting the forces and moments on a store during weapon separation based on previous wind tunnel data for another store in the same flow field. This new technique uses conventional grid survey store force and moment data and parameter identification analysis to 'identify' the local angle-of-attack distribution in proximity to the parent aircraft. Predicted force and moment characteristics for other stores based on this derived angle-of-attack show excellent correlation with supersonic data. The evidence to date indicates that the method will be applicable to virtually all stores at subsonic-supersonic Mach numbers. (Author)
