THE DESIGN METHOD RESEARCH FOR THE POSITION OF HIGH PRESSURE CAPTURING WING

The high pressure capturing wing configuration is a novel conceptual form which improves lift and lift-todrag ratios by the coupling relationship between the body and HCW. Based on the deign principle, the HCW position is determined by body compression shock and its own compression shock, while it is hard to obtain directly using theory. In order to solve this problem, this paper developed a kind of e ective method to design the position of capturing wing. The method is based on the analysis of parameters which determine the position of capturing wing, combined with the uniform experimental design method, the computational fluid dynamics analysis and surrogate model building to obtain the relationship between the position of capturing wing and the design parameters. The results from the validation case of cone body combination with capturing wing showed that this method can determine the optimal position of capturing wing in a large design space. In addition, cone compression angle, free field Mach number and blunted radius of capturing wing are the key parameters a ecting the position of capturing wing for the cone combination capturing wing. The results from the analysis of surrogate model showed that the position of capturing wing is in monotonic proportional relationship among the above three parameters.
