ADVANCED THRUST CHAMBER ASSEMBLY PROGRAM.

Abstract

An exploratory development program was conducted to demonstrate the performance capability of a thrust chamber assembly using the advanced propellant system Compound A/MHF-5. Among the basic requirements was dual thrust level operation, boost and sustain, with the ability to select either thrust mode at random. Although not oriented toward any specific application, the program provided basic performance and design information which may be applied to future packaged liquid programs. The thrust chamber assembly (TCA) as defined for this program includes the annular thrust chamber, the injector, the thrust control slide, and the shear slide. A three-phase approach was taken to achieve the program objectives: an analytical phase to establish configuration and select propellants; a development phase to evaluate the selected designs and obtain performance data; and a hardware demonstration phase. During the program, several problems were encountered. A combustion instability problem was solved by compartmenting the annular thrust chamber. Encouraging results were obtained by using pyrolytic graphite overcome an annular chamber centerbody nozzle throat insert durability problem.
