| Abstract: | 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. |
