EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF SUPPORT INTERFERENCE ON THE PRESSURE DISTRIBUTION OF A BODY OF REVOLUTION AT A MACH NUMBER OF 3.12 AND REYNOLDS NUMBERS FROM 2xl06 TO 14xl06

摘要

An experimental investigation was performed to determine the effect on base and forebody pressures of using a sting modified with varying length splitter plates and fins instead of a conventional sting to support a cone-cylinder body of revolution. The investigation was conducted at a Mach number of 3.12 for a Reynolds number range of 2x106 to 14x106 and for an angle of attack range of 0° to 9°.nThe influence of the varying length splitter plates and fin modifi¬cations was confined to local disturbances on the forebody and base. With the splitter plate there was a negligible effect on body pressures and with the fin, a small effect on body pressures.
