Laboratory Injector for Spray Studies Related to Liquid Propellant Gun

Abstract

For the purpose of studying (on a laboratory scale) the injection processes typical of a Regenerative Liquid Propellant Gun (RLPG), an injector has been constructed and tested successfully. A computer code was written for prediction of the injector performance. The injector operates on the RLPG injector principle. It features internal gas chambers and accessories which enhance its operational controllability. The injector is capable of injecting circular as well as annular jets. With HAN-based liquid propellants, the injector is capable of injecting 3-mm-thick jets with velocities in the range of 100 to 300 m/s and mass flow rates of up to 10 kgs. This report describes the construction of the injector, its principle of operation, and its performance.
