Summary
The pyrotechnic output of TiH/sub x//KClO/sub 4/ loaded actuators has been determined from analysis of piston velocity data obtained from VISAR measurements. The effects of fuel stoichiometry, fuel/oxidizer ratio, and particle size are assessed. Computer-assisted curve fitting techniques have been employed to generate pressure-volume curves for the expanding gas and to perform Gurney analyses. The former imply that pyrotechnics containing TiH/sub 0/./sub 2/ or TiH/sub 0/./sub 65/ are fast burning and are largely consumed prior to piston motion, in contrast to those containing TiH/sub 1/./sub 9/. The latter yield values of the characteristic Gurney velocities and energy conversion efficiencies. Low efficiency values (5 to 10%) are obtained which are consistent with chemical and gasdynamic aspects of the combustion process.
