Earth Penetrator Design Study Program Subscale Ballistic Penetration Tests.

摘要

A series of 24 penetration tests were performed at various combinations of angle of attack and obliquity using three different models. Ogive, single stepped tier and conical tipped scale models were used to penetrate through concrete into a sand media. All tests were performed at 1000 ft/s. Copper balls were used to measure the peak deceleration for each test. Grids were used to monitor the penetrator trajectory and change of velocity through the sand media. Test results including velocity, angel of attack, obliquity, crater size, copper ball deformation, trajectory and change of velocity in sand media are reported. Variations in performance as a function of tip configurations are discussed. The results provide an extensive and significant addition to the understanding of the interaction between earth penetrators and representative target media. (Author)
