Prediction of Supersonic Store Separation Characteristics Volume I. Theoretical Methods and Comparisons with Experiment
Abstract
The primary objective of this report is to describe an investigation to develop a method for predicting the separation characteristics of a store released from a supersonic parent aircraft. The present computer program is designed to handle configurations consisting of a wing without dihedral or incidence which is attached to an axisymmetric fuselage. A pylon can be attached to the wing or under the fuselage. In this work, supersonic flow models are described to represent the configuration and special attention is given to the flow field calculation method. It is shown that the basic method utilizing linear, potential flow theory must be corrected for nonlinear effects caused by the shock from the wing leading edge. Experimental results are presented from a wind-tunnel test program designed to provide data to aid in developing and testing the theory. Comparisons between theory and experiment for flow fields, store loading distributions and store forces and moments indicate fair to very good agreement. Recommendations are given for improving the present method.
