Following a brief comparison of pulse-duration-modulation and proportional systems, a detailed program of analysis and experimentation is described in which thrustors throttled by high velocity transverse jets are evaluated. For a gas jet injected normal to the flow at the throat of a sonic nozzle, an analytical model was developed that gives excellent agreement with experimental observations. Experimental studies were conducted for a variety of jet and mainstream conditions and utilizing quantitative and qualitative techniques to describe the jetmainstream interaction. Within the range of the test results, insufficient mainstream throttling is attainable to warrant the use of the method as a proportional control device for missile steering thrustors.
