Investigation of Supersonic Inlet Mathematical Model with Attack Angle

At different attack angles,Mach numbers and ramp angles,the numerical calculations of inner and external flow field are performed for an adjustable mixed compression inlet.The full flow field characteristics of a supersonic inlet are illustrated at design conditions;The influence of attack angle on flow field of the inlet is investigated;B-spline theory is used to model the inlet with attack angle.On basis of the modeling results,the effects of Mach number,attack angle and ramp angle on the inlet performance are analyzed.
