THRUST-VECTOR CONTROL BY SECONDARY INJECTION

Abstract

The technique of thrust-vector control by injection of a fluid into the exhaust stream of a nozzle (secondary injection) was explored. This paper gives a survey of work performed at the Naval Ordnance Test Station during Fiscal Year 1959, previously reported in IDP 765. Both cold-gas (air) data with 3-dimensional and 2dimensional nozzles and data obtained with a liquid-propellant applied-research motor (LPARM) are presented. Fluids studied with the LPARM were N2O4, N2 (gas), H2O, and IRFNA. Physical parameters as well as fluid properties were considered in the tests. Injection of a secondary fluid increases the main thrust of the motor as well as producing a side thrust. Thrust-vector control by secondary injection is simpler and more reliable than mechanical controls and shows promise of becoming a replacement for them. (Author)
