中文摘要:
      为了提高军用飞机的空战和对面攻击能力,对歼轰机进行总体设计。采用CATIA软件,设计出隐身歼轰机的三维数字样机和武器挂载方案;基于物理光学法和等效电磁流法,采用自编的RCSAnsys软件,数值模拟歼轰机的数字样机在X、S和UHF波段下的RCS特性和强度分布特性;基于湍流模型的k-ε方程和控制理论的N-S方程,采用Fluent软件,数值模拟歼轰机的数字样机所在空气流场的压强和速度分布云图,得出整机的升阻特性。概念设计数值模拟结果表明:内置弹舱的歼轰机前向±30°的RCS均值[≤]-4.728 dBsm,超声速飞行时歼轰机的升阻比约等于5.633 7。
英文摘要:
      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 characteristics and intensity distribution characteristics of the fighter-bombers digital prototype in the X, S and UHF bands was studied. Based on k-ε equations of the turbulence model and N-S equations of the control theory, the distribution of pressure 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 characteristics of the fighter bomber was less than -4.728dBsm, and Supersonic lift-to-drag ratio was approximately equal to 5.6337.
