Use of the Flow Angularity Technique for Predicting Store Separation Trajectories.

Abstract

A method is being developed for solving the store separation trajectory problem by flow angularity techniques. This approach uses experimentally measured interference flow field data coupled with store free stream aerodynamic coefficients. Presently, the flow field about the inboard triple ejector rack loaded with M-117 bombs at Mach 0.85 on the F-4 aircraft is being used to predict the trajectory of other stores launched from the inboard triple ejector rack at subsonic and transonic Mach numbers. Sample comparisons of trajectories produced by the captive trajectory system are presented. This technique allows calculation of the trajectory until the store impacts on the ground. Sample miss distances caused by the interference flow field calculated using the flow angularity technique are presented for the M-117 bomb. (Author)
