  1. 导弹上的长鼓包对气动特性的影响

    Effects of Long Protrusions on Missile Aerodynamic Characteristics

  2. 它是通过测定齿轮在热处理淬火及焊后实际变形规律,在齿长修正中,采用反变形方式,校正主要变形趋势,同时采用齿长鼓形修正,以提高啮合质量,满足齿轮工作要求。

    By measuring and investigating the deformation rule of gears in quenching and after welding and applying reverse deformation model for addendum correction , the major deformation trend is compensated .

  3. 经风洞试验了解并证实,长鼓包对纵向气动特性影响不大,对滚转力矩稍有影响,特别是当攻角较大时,对滚转力矩有一定影响。

    The wind tunnel tests show that long protrusions have little effect on longitudinal aerodynamic characteristics , but a considerable effect on the roll moment especially at a large angle of attack .
