ANALYTICAL EXPERIMENT DEVICE FOR WING AMBIENT FLOW

摘要

PURPOSE: To visualize the flow field around a sample wing and simultaneously measure wall pressure, etc., in an analytical experimental device for wing ambient flow. ;CONSTITUTION: This device is provided with wings 5 planted in line in a cantilever form in a metal flat mirror 21 forming one inner wall surface of an air tunnel duct 2, a transmitting member 4 opposed to the flat mirror 21, a deflecting member 8 for changing the emitted light L₁ emitted from a light source 6 arranged on the outside into a parallel light L₂ and deflecting it in the direction toward the transmitting member 4, a slit member 10 arranged at the focus position F of the reflected light L₃ reflected by an translucent mirror 9 arranged between the deflecting member 8 and the light source 6, and an image receiving means 11 for imaging the reflected light L₃ passing the slit member 10. The pressure fluctuation of the wing ambient flow is visualized by utilizing the change of diffraction ratio of a supersonic air flow A in the air tunnel duct 2.;COPYRIGHT: (C)1994,JPO
