Abstract : The patent relates to a method whereby a novel injector is provided for a variable thrust rocket engines using the annular-stream variable-area concept to give fast response and shut-off capability. This is accomplished by a simple arrangement of an annular metering sleeve which surrounds the central pintle such that a fuel and an oxidizer are separately and simultaneously metered to the combustion area. The metering sleeve, and contoured baffles forward of the opening, aid in providing a good mixture ratio control and performance.
