| In decades，with the development of the economy and the military strength of our country,to research the advanced fighter aircraft in world has became an important strategy for ournational defense. Russian fifth fighter aircraft is an advanced fighter aircraft in the world, itsbiggest innovation is the design of the movable strake. This paper presented the3-D model ofT-50, and reconstruct it, then calculate and analyze the aerodynamic performance of the model.Reconstruction and aerodynamic analysis of abroad advanced fight aircraft will provide greatconference and guidance to the design of advanced fight aircraft in our own country. First,introduce the development of the overall shape of the aircraft, focus on introducing overallaerodynamic configuration of T-50. Second, extract the key points and lines from the three viewof T-50, but also refer to the photos of T-50at key points, making the model reconstruction closeto the real and complete reconstruction of T-50. Then use gambit to do unconstructed mesh andfluent software to calculate aerodynamic for T-50, the lift, drag, lift-drag ratio characteristics areanalyzed at subsonic, transonic and supersonic. Meantime, calculate changes of aerodynamiccharacteristics caused by flexion of movable strake, after calculate, by comparing stream linechart, vortex chart and pressure cloud in different deflection angel of movable strake, with theinfluence to aerodynamics done by movable strake analyzed and the related mechanismdiscussed... |
