In-Flight Measurements of Captive Loads on a Store as Compared with Wind Tunnel and Mathematical Simulations.
Abstract
A series of flight tests were made to acquire captive loads data on a store to compare with corresponding data from several wind tunnel tests with conditions matched as closely as possible as well as with the best mathematical models available. The store consisted of a Mk 83 bomb shape mounted on a triple-ejector rack (TER) on an F-4 aircraft which was instrumented complete with a standard research boom mounted on the nose. The flight conditions spanned Mach 0.6 to 0.9 in both maneuvering and steady flight. The data show good correlation between flight test and wind tunnel for moderate subsonic Mach numbers when good geometric similarity is maintained, but there is a pronounced divergence in this agreement as the Mach number is increased. Correlation between mathematical models of this problem and the flight test show the same magnitude in loads and moments, but the trends do not always agree. This is most pronounced in the pitch plane.
