Abstract:

Six tests were conducted at ambient conditions to evaluate the cutting performance of the NASA Gemini 52-72704 Flexible Linear Shaped Charge FLSC Cutter Assembly with dual titanium straps. One test was performed to demonstrate the effective severance of a dual titanium strap assembly with a thickness 123 percent of the nominal strap thickness 0.071 inch. Five tests were performed to evaluate depth of FLSC cutting as a function of gap distance between the FLSC and the strap. The cutter assembly was successfully initiated, and the strap assembly was completely severed during each test. FLSC cutting could not be distinguished from shearing of the strap due to hot gases and molten lead from the FLSC sheath washing across the severed surfaces of the strap assembly. The FLSC severance of straps demonstrated a Gemini B performance margin of 2.70 minimum in terms of installation gap. Author
