查询词典 backswept wing

In addition, it's computed that how the aerodynamic force of flexible flapping-wing changes with flap parameters, such as flap angle, flap frequency, and so on. The computed results explained why bird wing have different flap motions in different phases of flight, and provide theory for future design work of flapping-wing MAV.

此外，本文还模拟计算了时柔性扑翼气动力随扑动角、扑动倾角等参数变化的情况，从而从气动的角度解释了飞鸟在不同飞行阶段的扑翼规律，并为柔性扑翼飞行器的设计提供了理论依据。

Make sure the shape of the wing, especially if it is going downwards, is not conflicting with the gears ( if the wing's minimum Z coordinate is lower than the gear's, that means that when landed on the ground, the wing tip will be under the ground !).

要注意翼的外形，尤其如果它是朝下的，那不能与着起落架矛盾(如果翼的最小Z坐标低于起落架，那意味着当船着陆时，翼尖会戳进地面中！)。

Because the broadsword looks like the crane wing, so it is called Two Crane Wing Broadswords. Two Crane Wing Broadswords are the practical short weapon that you can easily carry, agilely use.
