一、引言 文献[1]曾用跨音速定常势流的混合差分法成功地计算了皮托管式轴对称进气道内外跨音速流场,本文进一步用上述方法计算了中心锥式进气道的跨音速流场。中心锥式进气道的通道形状大多为收缩-扩张型,内通道壁面扰动较强。同时,由于中心体的存在,使传递进气道出口反压扰动的横向松弛线被隔断,因此,在皮托管式进气道计算中行之 I. INTRODUCTION The literature [1] used the mixed differential method of transonic steady flow to successfully calculate the transonic flow field inside and outside Pitot tube axial symmetric inlet. In this paper, Transonic flow field. Center cone inlet channel shape most of the contraction - dilatation, the inner channel wall disturbance. At the same time, due to the presence of the center body, the transverse slack line, which transmits the disturbance disturbance of the inlet port, is cut off. Therefore, in calculation of the Pitot tube intake port
