Effects of Base Bleed and Supersonic Nozzle Injection on Base Pressure
Abstract
Base pressure tests were conducted on an ogive-cylinder configuration at Mach numbers 2.5, 3.0 and 3.5. Measurements were obtained while bleeding air into the base region through a variety of base-bleed configurations. For two of the configurations, air was injected into the base through a supersonic sustainer type nozzle simultaneously with base bleed injection. The mass flow rates through the sustainer nozzle and base bleed openings were varied at each Mach number. The results show a net decrease in base drag due to base bleed and a net increase due to supersonic injection whether or not the bleed air and the supersonic air are introduced simultaneously.
