SIMULATION AND EXPERIMENT OF HYPERSONIC WAVERIDER FOREBODY INTEGRATED WITH INLET
A new method to quickly generate hypersonic waverider forebody configurations has been developed. The new method is an extension of the analysis method and power law method and is called osculating analysis method. In this method the constraint of creating only one attached shock wave in waverider forebody design by analysis or power law method is removed. More than one attached forebody shock waves can be created in this method.For the purpose to integrate with ramjet or scramjet, a hypersonic forebody integrated with inlet was designed. The design objective is that the hypersonic forebody has three attached shock waves in the design flight condition.To better understand the forebody performance, three dimensional flow field calculation of the design waverider forebody (designed by osculating analysis method) integrated with hypersonic inlet and two comparative reference waverider forebodies(designed by analysis method and power law method, respectively) integrated with hypersonic inlet in the design and off design conditions were conducted. The computational results show that the performance of design waverider with three attached shock wave is great better than that of two comparative reference waveriders.Test of the design waverider forebody integrated with hypersonic inlet was performed at a 500-mm-diameter hypersonic tunnel. Experimental results were obtained for a range of conditions, including the on-design Mach number and off-design Mach number conditions. Experimental results were greatly agreed with those of CFD predictions. Vapor screen results for the model indicate three attached (or very nearly attached, within the limits of observation) shock waves along the entire leading edge. CFD predictions generally agree with the measured pressure distribution.
