摘　　要：本文应用有限元法求解跨声速流中带有斜支架的任意型面空速管(L型空速管)的压强分布,控制方程为全速位方程,来流可具有迎角。本文方法为设计气动补偿空速管提供一种有效手段,能大量节省方案筛选的风洞实验工作量。对典型型号的计算结果与风洞实验数据的比较表明本文方法是有效的。In this paper, the finite element method is employed for the solution on the pressure distribution of the Pitot tube of arbitrary profile with the oblique support (L-type Pitot tube) in the transonic flow regime.The governing equation is full potential equation. The free stream flow may be of angle of attack. The present method provides an effective means for designing aerodynamic compensative Pitot tube .That can considerably saVe the works of the wind tunnel test to screen the projects .Comparisons between the computations and experiments for the typical products have demonstrated that the present method is successful.
