Abstract:

A 5.0-inch, storable, liquid-propellant propulsion system utilizing the hypergolic propellant combination of IRFNA and UDMH was designed and tested. Nine motor assemblies were static-fired, and 6 motors were flight-tested in a configuration capable of being used as a guided target rocket. This design provides positive expulsion of the propellants under all flight conditions. Nominal thrust with a Centro-mix injector is 200 lb for 33 sec with a variable-thrust injector designed to be used with the system, thrust is variable from 50 to 300 lb. The 5.0-inch liquid target motor features welded aluminum alloy propellant tanks that are opened simultaneously by a bipropellant explosively actuated valve a 3500-psi N bottle as the source of pressurizing gas a stainless steel combustion chamber with a graphite liner and a simple injector.
