Comparison of Wind Tunnel and Flight Test Measurements of Static Aerodynamic Loading of a Captive Store

摘要

A coordinated series of experiments was conducted in three wind tunnels and in flight to measure the static aerodynamic loading of a MK 83 store attached to the bottom center station of a triple ejector rack mounted on the left inboard pylon of an F-4 aircraft. Fundamental agreement between wind tunnel and inflight loads data was demonstrated over a range of angle of attack from -2 to 6 deg and a Mach number range from 0.6 to 0.9. Differences that were noted were thought to be attributable either to improper store-to-aircraft alignment or to poor definition of inertial loads during maneuvering flight. (Author)
