Analysis of Harpoon Missile Structural Response to Aircraft Launches,Landings,Captive Flight and Gunfire.

摘要

During its service life the HARPOON missile will be exposed to various types of shock and vibration loads which pose a reliability hazard to the missile and its equipment. This report discusses the response of the HARPOON missile to shock loads during catapult launches and arrested landings of the missile-carrying aircraft, long-term vibration during captive flight, and short-term vibration induced by aircraft gunfire. To evaluate the missile's response to these shock and vibration loads, a number of catapult launch and arrested landing tests were performed using an A-7E aircraft carrying an instrumented HARPOON missile; extensive captive flight vibration and surface pressure measurements were made for various flight conditions and carrying positions of the instrumented missile on A-7C, S-3A, and P-3C aircraft; and vibration caused by gunfire during the A-7C tests was measured. Although the primary purpose of this measurement program was to obtain HARPOON missile structural response data for comparison to the HARPOON environmental design criteria, also of interest was a comparison of the measured response levels to the test criteria of applicable specifications, as well as other available data for similar missiles.
