桨叶

Each blade subassembly has a pair of interconnected propeller blades extending in opposite directions radially of the shaft.

每个刀片组件有一个对相互关联的螺旋桨桨叶延长在相反的方向径向的轴。

STRUCTURE: Titanium and composites used extensively, with particular emphasis on corrosion resistance; fully articulated three-blade coaxial contrarotatmg rotors have all-composites blades with carbon fibre and glass fibre main spars, pockets (13 per blade) of Kevlar-type material, and filler similar to Nomex; blades have non-symmetrical aerofoil section; each has ground-adjustable tab; each lower blade carries adjustable vibration damper, comprising two dependent weights, on root section, with further vibration dampers in fuselage; tip light on each upper blade; blades fold manually outboard of all control mechanisms, to folded width within track of main landing gear; rotor hub is 50% titaniuin/50% steel; rotor brake standard; all-metal fuselage; composites tailcone; fixed incidence tailplane, elevators, fins and rudders have aluminium alloy structure, composites skins; fins toe inward approximately 25°; fixed leading-edge slat on each fin prevents airflow over fin stalling in crosswinds or at high yaw angles.

结构：钛和复合材料广泛使用，耐腐蚀性能与特别强调，充分阐明三叶片转子同轴contrarotatmg有碳纤维和玻璃纤维的主要棒材全复合材料桨叶，口袋（每刀片13）凯夫拉型材料，类似的Nomex纤维填料；叶片非对称机翼部分，每有地面可调选项卡，每降低叶片振动阻尼器进行调节，包括两部分依赖重根，在机身进一步减振装置；小费每个刀片上轻；刀片倍手动舷外所有控制机制，折叠宽度内的主起落架的轨道；转子中心为50％titaniuin/50％钢；转子制动标准；全金属机身，复合材料tailcone，固定发生机尾，电梯，蛙鞋和方向舵的铝合金结构，复合材料的皮肤；鳍鳍在每个脚趾向内约25 °；固定领先的板式翅片防止了侧风或气流停滞在高偏航角度。

Said torsion spring is increasingly stressed torsionally as the wind acting on said propeller blades increases in velocity and, as the torsional stress on said spring reaches a certain magnitude, said spring moves at least partially away from said first abutment member and, with increasing torsional stress on said spring, through the intervening angle between said abutment members and into engagement with said second abutment member.

说扭簧是越来越强调扭矩为风署理就表示，螺旋桨桨叶的增加速度，由于扭应力就表示，春季达到一定的规模，说春天的举动，至少部分远离说，第一台的成员，随扭应力对说，春天，通过干预之间的角度说，坝肩成员和到接触说，第二台的成员。

Although the miniature of this woodiness paddle is wind- driven dynamo before long bad, but, the historical sense that it produces is particularly great however.

尽管这台木质桨叶的微型风力发电机不久就坏了，但是，。。。。。。

As such most of the leading brands nowadays provide for the arrangements of ornamental "fitters" tucked beneath the blades to support lamps and their decorative shades.

因此大部分的领导品牌，提供现今的安排观赏&识时务&的真相下方桨叶支持灯具和装饰阴凉处。

Unfortunately, though, because of the aerodynamics and gyroscopic effects of the blades, all these controls are related.

不幸的是，由于桨叶的空气动力学效应和回转效应，所有这些控制都是相关联的。

A theory of aeroelastic stability of hingeless rotor blade in hover by using the Galerkin weighted residual finite element method is developed in this paper.

采用伽辽金加权余数有限元素法发展了一种悬停状态下无铰旋翼桨叶气弹稳定性的分析方法。

In the method ,the blades are treated as rigid ones with offset and spring restrained hinges and with structural coupling between flap and lead lag motion for the purpose of being applicable to hingeless or starflex rotors .

采用带外伸量及弹性约束的当量铰桨叶模型，考虑了旋翼挥／摆结构耦合及动力入流非定常气动力，建立了悬停状态旋翼／机体耦合动稳定性分析方法，适用于星形柔性及无铰式等旋翼系统。

We also used a hyperboloidal panel to eliminate the g...

Newton-Raphson迭代过程被用来在桨叶随边满足压力Kutta条件。

Then comes the more powerful CH-47B with the Lycoming T55-L7C engine, which was introduced by Boeing after a production run of over 350 CH-47A's. On the B model there are nonsymmetrical rotor blades to increase the stability.

因此波音公司在推生产了350架CH-47A后，推出了更加强劲的配备莱克明T55-L7C发动机的CH-47B型。B型为提高稳定性，还配备了非对称性的旋翼桨叶。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
