Computer Prediction of Store Aerodynamic Loading during Separation.

Abstract

An advanced fighter design is modeled using the Nielsen store separation and trajectory program with the non-circular fuselage cross section option. The theory required to build the computer model is consolidated for better understanding, with the major points referenced to the appropriate report. The details of the process to generate the computer model are described. The computer model of the aircraft and ogive store is used to predict store forces and moments which are compared with wind tunnel results on the same configuration. The prediction accuracy, at Mach number 0.6, at a store position of three store diameters away from the aircraft, is within ten percent of experiment in the region of interest, which is the area under that portion of the fuselage occupied by the wing.
