查询词典 downwash

In June 1919, Henry Berliner built a machine with two co-axial propellers with vanes to vector the downwash for pitch control.

在1919年6月，亨利柏林建造的两个合作轴与叶片为载体，以螺距螺旋桨气流控制一台机器。

In this thesis,the rolling moment characteristics of canard missies are studied,and theinfluence of downwash of canard was analyzed.

本文讨论了鸭式布局弹箭的滚转气动特性，分析了鸭舵的下洗影响作用。

Also important are the rotation of the slipstream and the change of downwash at the tail.

此外，滑流的旋转和尾翼处下洗的变化也是重要的因素。

With no torque to counter, the "Hornet" dispensed with a tail rotor in favor of a simple airplane-style rudder canted to take advantage of rotor downwash.

由于没有转矩柜台，&大黄蜂&与旋翼下洗配一个优势尾桨赞成采取简单的飞机，到样式舵斜。

The digital model of hel icopter main motor downwash flow and missile dynamics was established. The variation of the missile attitude and traject ory under rotor downˉwash flow are analyzed through simulation, the variety curves of them are provided on both cond itions that with or without the control of autopilot.

通过建立直升机下洗流场数学模型和导弹动力学和运动学模型，对导弹在旋翼干扰流场下的姿态和弹道变化进行了仿真研究，给出了在导弹自动驾驶仪启控或不启控状态下旋翼下洗流干扰对导弹姿态和弹道影响变化曲线。

The result indicates that the rotor downwash flow has an obvious inf luence on the missile, but with the control of autopilot the effect can be minished evidently.

结论认为下洗流场对导弹初始弹道的影响是显著的，导弹自动驾驶仪的控制作用可有效减小这种影响。

This induced component of velocity is called downwash, and it reduces the amount of lift produced by the wing.

这种诱导速度构成了所谓的下洗气流，而且它使机翼产生的总升力减小。

Results show that in hover the fuselage normal force and pitching moment are relatively high due to the influence of rotor/wing downwash; and in low speed forward flight, the downwash have strong interaction on the normal force and pitching moment of fuselage due to the big dimension horizontal tail; the effects of downwash on the fuselage rolling and yawing moments are little and the influence on fuselage side force is considerable.

结果表明，悬停时受主机翼高速旋转产生的下洗尾流影响，机身产生了较大的法向力和低头力矩；前飞时下洗尾流对机身的法向力和俯仰力矩有比较严重的干扰，对滚转力矩和偏航力矩干扰较小，对侧向力有一定影响。

With the increase of the downwash flow velocity, the exhaust temperature has a peak value the exhausting duet temperature decreases with the increase of the downwash flow velocity.

结果表明，模型出口排气温度随着主喷管流量增加而线性增加，引射系数随着下洗气流速度增加而减小，出口排气温度随下洗气流增加时有一个峰值，增加下洗气流速度有助于降低外套壁温。
