Abstract

The basic inward turning cone was designed by methods of characteristics which were represented by straight initial shock wave and inner compression section shock wave cancelation

controllable flow parameters and uniformity exit inner compression section. The integrated osculating inward turning cone waverider inlet(OICWI) design methods were developed based on the osculating inward turning cone (OIC) waverider design methods. Based on the designed basic inward turning cone flow field and OICWI design methods

an OICWI was designed. The OICW's performances were analyzed by numerical ways. The results show that:(1)The integrated waverider inlet design methods agree well with aerodynamic principles. (2)The waverider-inlet's shape can be easily controlled by adjusting inlet capture curve

front capture curve and basic flow field structure. (3)Numerical simulation results agree well with the design results and the flow field structures are consistent with each other

showing that the integrated design methods are correct. (4)The viscous results on design and off-design conditions show that OICWI has high pressure recovery and flow capture characteristics

and the flow field parameters are uniform in the inlet exit plane.
