An experimental investigation of compression fields in a supersonic flow through an annular duct is described. Compression fields were generated in an axisymmetric annular duct by overexpanding compressed air, relative to an ambient exhaust condition, to Mach 1.66, 2.35 and 2.89 with Reynolds numbers, Re, less than 26000. One purpose of the investigation was to acquire and evaluate data on hypersonic inlet performance for a Dual Combustion Ramjet (DCR) engine. The DCR precombustion shock train must be physically isolated from the external compression field of the air inlet in order to prevent undesirable combustor/inlet interactions. A second objective was to evaluate the structure of shock waves in a supersonic flow through an annular duct and compare it to the analogous flow through a cylindrical duct. As the supersonic air flow leaves the annular duct, it enters a cylindrical duct and is entrained by an inner coaxial jet. The effect of varying various DCR related test variables on the position of the compression field is evaluated. This quantification may be useful in the analysis of internally ducted supersonic flowfields subjected to adverse pressure gradients.
