Abstract : During the current reporting period, work was done in the following areas; test equipment calibration, fabrication of tooling and test equipment, preliminary engineering drawing release, fabrication and testing of typical construction specimens, fabrication of the prototype Case HXL-1-477, and hydrostatic and drop testing of the prototype Case. Tests were conducted on small specimens of typical construction using 1.2 lb/cu ft density core to simulate energy absorption cylinder and end caps. The test results showed agreement with the theoretical deceleration calculations. Hydrostatic and drop tests were conducted on the prototype Case HXL-1-477. The hydrostatic test resulted in leakage in the energy absorption core. The drop tests resulted in high peak levels caused primarily by rigidity of the edge potting and the skins.
