使偏航

In the case of nacelles with active yaw systems, it shall be ensured that even straightforward manual maloperation cannot produce conditions which put the integrity of the wind turbine at risk as a result of stresses not included in the calculations.

在机舱配备主动偏航系统情况下，应确保即使是简单的人为不正确维护，也不会产生使风机的完整性承受未计算强度的危险。

To prevent possible danger to the wind turbine struc-ture, it may be advisable to suppress the automatic untwisting at extremely high wind speeds (e.g. V ≥ 0.8 * Vref) and to have the yaw system control the plant automatically until these wind speeds have dropped to an acceptable level.

为防止风机结构上可能的危险，建议在风速极高情况下（如：V≥0.8*Vref）抑制解缆操作，且应使偏航系统自动控制机组，直到风速降到一个可接受的级别。

Steering is done partly by precessing a 65-pound gyroscope to give yaw, and partly by the rider shifting his weight.

督导是做部分由precessing一个65磅的陀螺仪，使偏航，部分骑转移他的体重。

In order to reduce the expend of the development of TV guidance bomb, it refits the servo actuators of some missile for the servo actuators of the pitching loop and the yawing loop, and then, it tests the characteristic of the actuators and makes the actuators satisfy the basic requests; for the tumbling loop, the servo actuator adopts three-position relay control fashion to make the loop be stable by using the relay control circuit, the three-position and five-passage valve and the gas amplification device.

为了降低电视制导炸弹的成本，对于俯仰、偏航稳定回路，采用某型号导弹的舵机进行改装，并对改装后的舵机的特性进行测试，使舵回路达到一定要求；对于滚转稳定回路，采用三位置继电控制舵，通过继电放大器、三位五通阀和气动放大器来控制舵面的偏转，以此来实现滚转稳定。

The rudder serves the purpose of yawing the airplane to the right or left.

2方向舵的用途是使飞机能够左右偏航。

This paper presents a wind vane sensors without the use of cases, combining with gyroscopes and hill-climbing algorithm to control the yaw institutions, can accurately capture the wind direction signal, rapid-conditioning the cabin of the deflection angle, so that wind generators wind wheel normal direction of the wind direction and change is always consistent for maximum capture of wind energy control strategies.
