翼的

Based on a hydrofolic small waterline area ship scheme with fixed hydrofoils, this paper researched the resistance, static stability, dynamic stability of HYSWAS by theoretical methods.

提出了一型采用非自控组合水翼系统的单体小水线面水翼复合型高速船方案，并对其进行了阻力、横稳性以及运动稳定性的理论分析。

However, at least one type of pterosaur ''did'' have at least the ''Pteranodon''-like crest and teeth--the ''

然而，有一种翼龙类的确有无齿翼龙的冠饰，而且有牙齿；'' Ludodactylus''，名字意思为&玩具翼手龙&，因为它外表类似儿童的翼手龙玩具外貌。

Of all the creatures that ever lived, pterosaurs probably most closely resemble the dragons of European legend.

翼龙 史上所有动物中，翼龙可能是最接近欧洲传说中&龙&的形象的动物了。

In addition to wind tunnel testing, transition (between vertical and wing-borne flight) testing was conducted with a novel truck-mounted fixed-wing rotorcraft model (Fig. 7) that was driven up and down Muroc Dry Lake and the Bonneville Salt Flats.

此外 ，风洞试验，过渡（垂直和机翼之间传染飞行）测试是一种新型车载固定翼旋翼机模型（图7 ）这是驱动的向上和向下Muroc干湖（现在的爱德华兹空军基地）和巴纳维亚盐带平地。

Through a series of computations, potential velocity distributions of foil surfaces are solved.

前者用于计算由平面上的圆直接生成的翼型，后者用于计算一般翼型。

Each of the wings buttress the others via a six-sided central core, or hexagonal hub.

每一个翼通过中心的六边形筒支撑着其他的翼。

Tiltrotor aircraft has a tilting proprotor at the tip of wing.

倾转旋翼机的机翼端部装有一个可倾转的旋翼。

Phenomenon. There is an article of Chuck in an old rotorcraft magazine where he computes the time to a Bensen gyro to do a 180 roll over when you have a down vertical gust and no horizontal stabilizer.

一篇文章中提到过某架没有水平尾翼的本森旋翼机在做180度翻滚试验，目标是计算当整个旋翼机倒置向下的时候所需时间。

The W-shaped tailless aircraft has not stabilizer and vertical tail,and it is based on the design of forward-swept wing and the integrated design of blended wing-fuselage.

W型无尾飞机基于前掠翼及翼身融合的一体化设计，取消了平尾和垂尾，可大幅降低雷达反射截面积，减轻结构重量；同时具有亚声速气动效率高、横航向操纵面效率高的优势。

It is a good practice to check the bolts and nuts on the main rotor head and tail rotor after every flight.

每次飞完检查主旋翼头和尾旋翼头的螺丝螺母是一个很好的习惯。

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。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
