自动倾斜器

本文介绍了一种对全尺寸旋翼在旋转状态下通过自动倾斜器激振，对应变响应的分析找出其固有频率的试验方法。

This paper presents a test method to find out natural frequencies of the rotating full scale rotor system by exciting the swashplate and analyzing the response of the blade .

电控旋翼直升机以襟翼操纵代替自动倾斜器操纵，与传统直升机相比，具有结构简单，重量轻，安全性好，便于维护等优点。

Compared with the conventional helicopter , helicopter with electrically controlled rotor ( ECR helicopter ) replaces swashplate with trailing-edge flap for primary rotor controls , the advancements of the former have simple structure , light weight , improved safety , convenient for maintenance and so on .

文中提出基于BP神经网络方法对直升机自动倾斜器竖向振动进行识别及评估。

The present paper develops a method for identifying the vertical vibration of Auto bank unit of helicopter using artificial neural networks .

具有线性扭转桨叶的变距角，其中含有自动倾斜器和挥午调节的作用；

The feathering angle of the rotor blades with linear torsion , including the action of the swash plate and flapping adjustment ;

如已知自动倾斜器的倾斜角，则上述后两组动力学方程可用来确定拾个旋翼的挥午系数和偏摆系数。

If the inclined angles of the swash plate are known , the above equations of the last two groups may be used to determine the ten coefficients of the flapping-lag motion of the rotor blades .

试验结果表明，电控旋翼的襟翼总距和周期变距操纵效果与常规旋翼类似，电控旋翼完全可以取代传统的自动倾斜器操纵系统实现旋翼操纵。

The test results showed that the control effect of the ECR flap collective and cyclic was just like the traditional rotor . While in forward flight tests , obvious cyclic effect due to flap collective deflection could be observed .
