超声速隐身歼轰机概念设计数值模拟
Numerical Simulation of Supersonic Stealth Fighter-Bombers Conceptual Design
摘要
Abstract
In order to improve the air combat and attack capability of military aircraft, the overall design of fighter-bomber was focussed on. Using CATIA, a 3D digital prototype and weapon solution of the stealth fighter-bombers was designed. Based on the physical optics method and the equivalent electromagnetic flow method, using RCSAnsys, the RCS character-istics and intensity distribution characteristics of the fighter-bombers digital prototype in the X, S and UHF bands was studied. Based on k-εequations of the turbulence model and N-S equations of the control theory, the distribution of pres-sure and velocity around the fighter-bombers digital prototype in air flow field with fluent software was studied, and the lift drag characteristics of the aircraft was obtained. The simulation results showed that the range of the ± 30 °RCS characteris-tics of the fighter bomber was less than-4.728dBsm, and Supersonic lift-to-drag ratio was approximately equal to 5.6337.关键词
