Solid gas generators for chemical lasers
Abstract
Solid gas generator formulations which produce H2, D2, and a mixture of F2 and NF3 have been developed for HF/DF chemical lasers. NF4BF4 has been chosen as the oxidizer candidate for the F2/NF3 solid gas generator. A continuous reactor for the photolytic production of NF4BF4 was designed and assembled. A production rate of 5g in one hour of pure NF4BF4 has been achieved. The F2/NF3 solid gas generator formulation NF4BF4/KF/Sn was selected for further evaluation. Burning rates of the order of .08 cm/sec and yields of approximately 34 wt% available fluorine have been realized. Pressed pellets exhibited excellent mechanical and safety characteristics. A mixture of LiAlD4 and ND4Cl has been selected, characterized and test fired at the 1500g level at a burning rate of 0.064 cm/sec. A point design concept for a F2/NF3 fuel system has been developed incorporating existing laser and gas generator technology.
