Abstract:

Schlieren photographs were taken of the flow over cone-cylinder-flare bodies to study the extent of boundary-layer separation due to the presence of rocket jet plumes. Tests were made of three cone-cylinder-flare configurations in the Langley 11-inch hypersonic tunnel at a Mach number of 9.65 and in the Langley Unitary Plan wind tunnel at a Mach number of 4.65 with two additional configurations. The stream Reynolds number varied from approximately 317,000 to 582,000 based on model length. The conical flares had half-angles of 7 or 13 degrees and contained one of two test nozzles with a design Mach number of 3.72 or 4.53.
