摘要
通过对后体上翘的运输类飞机机身(机身+起落架舱)的CFD数值模拟,研究了起落架舱对机身最小阻力攻角的影响。结果表明:对于后体上翘较大的运输类飞机,相对于净机身,加上起落架舱后,机身阻力增加,但最小阻力攻角明显减小。
A computational investigation of the impact of landing gear cabin on drag has been conducted.Numerical simulations on fuselage of transport airplane with/without landing gear cabin were taken by solving RANS equations with SA turbulence model.The primary emphasis in this paper is on fuselage with afterbody of 17°upswept angle.The comparison shows that drag increases,but the attack angle of minimal drag is obviously decreased on fuselage with landing gear cabin.
