Description
Summary:The purpose of testing was to perform Nondestructive Evaluation (NDE) of the HARPOON weapons system. In particular, the intent was to investigate the effect of modified shock isolation pads on the dynamic response of the missile/ canister were compared. The testing was conducted with the production style isolation pads and a modified pad designed to reduce cost and installation complexity. The proposed isolation pads were prototypes, so the testing was exploratory in nature rather than aimed at qualification. To accomplish this task, four HARPOON Grade-B canisters on a Launch Support Structure (LSS, were subjected to a modified portion of vibration testing. HARPOON dynamic simulators were placed inside two of the canisters, while the other two were trainers. MIL- STD-167 vibration levels were chosen since the HARPOON system was designed to this requirement. During the testing the acceleration response at a number of points on the structure was monitored. The location of these points was chosen to provide information on the influence of the pads, as well as the general response of the entire structure.
