Aerodynamically coupled direct flutter analysis of long-span bridges .
大跨度桥梁结构气动耦合直接颤振分析。
In terms of upgrades , we have three or four things to be tested here aerodynamically and mechanically and I expect them to work .
至于升级,机械跟空气动力方面我们有3、4个部件这这里测试,我希望他们能起作用。
This enables it to bend aerodynamically , with simultaneous weight displacement , and is responsible for the smartbird 's agility and maneuverability .
这使得它能够符合空气动力学进行弯曲,同时获得重量位移,并造就了smartbird的敏捷性和机动性。
A modern sports glider , with long , slender wings , is the most aerodynamically efficient aircraft , with a lift-to-drag ratio of around 50:1 .
现代运动用滑翔机的机翼长而细薄,拥有最佳的空气动力学效率,其升阻比达到50:1。
Motors rotate four tiny fins to change their angles . The bullet is heavy toward the tip , like a dart , so it 's aerodynamically stable and can fly straight .
马达旋转四个小型翼来改变他们的角度,子弹尖端很重有点像箭,所以它的空气动力很稳定,可以直线飞行。
Fox clothing makes all different kinds of cycling clothing , from the looser fitting jerseys and shorts to closer fitting clothing that is more aerodynamically designed .
