On the CFD support for the Hyper-X aerodynamic database

Three dimensional inviscid CFD results in support of the Hyper-X vehicle aerodynamic database are presented. Specifically, the effects of Mach number, sideslip and angle-of-attack disturbances on the Hyper-X vehicle stability and control have been studied extensively. Results show the vehicle to be stable under a sideslip disturbance for the two geometric configurations studied (inlet open and closed). However, an angle-of-attack control mechanism is needed to stabilize the vehicle. In addition, the CFD results are used to assess the feasibility of Flush-AirData-Sensors to measure the angle-of-attack and sideslip angle. Based on these results, it is found that the proposed locations of the sensors are not optimal ones. Alternative locations are suggested.
