翼的

The team also noted a hinged flap near the base of the wing, called an Alula, which is deployed at right angles to the wing, which may be being used as a air flow-control device.

这个小组还注意到，翼根附近铰接的副翼，被称为小翼的，对翼成直角配置，它可能被用来作为空气流量控制装置。

The influence of the instantaneous angle of attack and ST on the performance of propulsion is investigated.

以鱼类尾鳍摆动式推进模式为背景，对二维刚性和柔性水翼摆动运动的非定常水动力性能开展了数值计算，将刚性水翼的计算结果与实验值进行了对比，吻合较好。

The ratios of thickness and camber of wing profile have significant influence on the aerodynamics of WIGs.

翼剖面的厚度和拱度对地效翼的气动力特性也有重要影响。

A variant of the swept-back wing is the delta wing.

后掠翼的变型是三角翼。

However, most airframe design involving canards do not have a tailplane and have thing to compensate for the effect of the flaps.

然面，多数采用鸭翼设计的飞机没有尾翼，没什么能抵消掉鸭翼的动作。

The static aerodynamic characteristics of the projectile are computed using the software of CFD, the results of the numerical simulation are agreement with the engineering calculation, this verifies that the results of the static aerodynamic characteristics of WAF from engineering calculation are satisfactory.

应用CFD软件对弹静态气动特性进行数值计算，数值计算结果与工程估算结果吻合较好，说明卷弧翼的静态气动特性可以通过平板翼进行估算。

The surface piercing hydrofoils can improve the static stability of HYSWAS with fixed hydrofoils when foil borne

对于采用非自控水翼的HYSWAS，割划式水翼可以明显地改善其稳性

This method is based on the blade second-order lifting-line model, the full-span free wake model, panel model for the fuselage and rotor trim model. By iterating induced velocities on the fuselage surface caused by rotor/wake and those on the rotor plane/wake caused by fuselage, a comprehensive analytical model is established.

该方法建立在桨叶的二阶升力线模型、旋翼的全展自由尾迹模型、机身的源面元模型、旋翼的配平模型的基础上，通过迭代旋翼/尾迹在机身上的诱导速度和机身在桨盘平面、尾迹定位点的诱导速度，形成一个全耦合的综合分析模型。

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！)。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
