Abstract:

The primary objective of this report is to describe an investigation conducted to develope a method for predicting the trajectory of a store separated from an aircraft flying at supersonic speeds. The aircraft model can include a circular or noncircular fuselage, engine inlets, wing, pylon, ejector rack, and circular and noncircular stores. The linear, potential flow methods used to model the aircraft components are described as are nonlinear corrections which are made to position shock waves more accurately. The methods used to calculate the nonuniform flow field, the store forces and moments, and the store trajectory are presented. Comparisons between theory and experiment for flow fields, store loading distributions, store forces and moments, and store trajectories are shown and discussed. Author
