Results of a Wind Tunnel and Flight Test Program to Develop a Maximum Volume Bomb (MVB) Configuration for Multiple Carriage and Separation from Tactical Aircraft at Mach Numbers from 0.50 to 1.10
Abstract
Wind tunnel tests, supported by flight test data, were conducted in order to determine separation characteristics of a 16-in. -diam maximum volume bomb (MVB) from the inboard-pylon triple ejection rack (TER) on the F-4C aircraft. The wind tunnel tests were conducted to obtain static and dynamic stability data on the store in the free stream, and captive trajectory data on the store when released from the F-4C and A-7D aircraft. The fins of the MVB were canted from 0 to -12 deg, with and without fin tabs, to assess their effectiveness in reducing the severe nose-down pitch motion encountered during separation at high subsonic Mach numbers. The tests were conducted at Mach numbers from 0.50 to 1.10 at simulated pressure altitudes of 5,000 and 20,000 ft. The wind tunnel tests indicated, at all Mach numbers, that the nose-down pitch motion of the store was significantly reduced by canting the fins. However, the flight tests at Mach number 0.90 indicated that the severe nose- down pitch motion continued even with the canted fins.
