Calculation of the Response of Adaption Kits in Accidental Side Impacts

This report describes the current study of the response of adaption kits in accidental side impacts. The primary goal of the project is the further development of finite element models for a generic missile structure so that adaption kit response, particularly component accelerations, can be predicted for side impacts of the missile. An additional goal is experimental determination of the impact response of a missile structure that contains a hard link safe-arm device. The work planned consists of four tasks. In Task 1, finite element models are being developed for substructures and checking the models' predictions against experimental data. In Task 2, the models are being used to calculate the response of complete structures, again by comparing the predictions with experimental results insofar as feasible. In Task 3, the analytical capabilities developed in Tasks 1 and 2 are being transferred by implementing the SUPER code at ARRADCOM. In Task 4, impact experiments are being performed on scale models of a specific prototype missile structure to help plan some fullscale tests.
