A Study of the Unsteady Flow over Concave Conic Models at Mach 15 and 20
Abstract
Pressure measurements and high speed cone schlieren photography have been used to study the unsteady flow behaviour of the Mach 15 and 20 flow over families of concave conic model shapes. The test flow parameters achieved closely simulate aerodynamic reentry conditions. The unsteady flow behaviour was found to resemble that found on certain configurations of spike cones. The shape of the concave surface and the Reynolds number were found to be important parameters controlling the type of unstability. Further test programmes are considered necessary to understand the flow processes and to define the boundaries of the instabilities.
