| 摘 要： | 通过数值求解三维NS(Navier-Stokes)方程组,对正常式布局战术导弹超声速绕流进行了数值模拟.来流马赫数等于2.0,来流高度20 km.计算中采用三种不同大小的舵面与弹体缝隙,分别为0.005,0.015和0.025倍弹径.得到了不同攻角、不同舵偏状态的舵面气动载荷,主要研究了舵面与弹体间缝隙大小对迎风面与背风面舵面法向力系数及舵面压心位置的影响.数值计算表明,舵面缝隙变化对舵面气动特性影响很小.

| Abstract: | The supersonic flow over the missile is simulated numerically by solving Navier-Stokes equations.The gap effect on aerodynamic characteristics for fins are investigated.The aerodynamic loads at different fins deflection are evaluated when the gap is 0.005,0.015 and 0.025 respectively.The free Mach number is 2.0.The numerical results show that the different gap results in a little complicated change of the aerodynamic characteristics. |
