| 摘 要： | 以远程能量传输飞行器为研究背景,基于FLUENT软件求解三维非定常欧拉方程,对飞行器外形的复杂绕流场进行了数值模拟,对飞行器机身及全机在腹部能量入射舱打开和关闭状态下的气动特性进行了计算和分析.结果表明:飞行器腹部能量入射舱开口对单独机身所带来的气动性能损失很大;对全机的升力影响很小,而对全机的阻力和升阻比影响较大.

| Abstract: | At the background of Long-distance energy transmission aircraft,the complex flow around an aircraft was numerically simulated with the three-dimensional unsteady Euler's equation.The aerodynamic attributes performance with two kinds of the aircraft were calculated,analyzed and compared with,one belly energy incidence door was opened,and the other was closed.The results show that belly energy incidence hatch causes great aerodynamic loss for separate fuselage;it causes less effect on the lift and more on the... |
