FLAP ANGLE MEASUREMENT SYSTEM AND METHOD
Abstract:
The invention relates to a system for monitoring movements of the rotor blades attached by flapping hinges (7) to a central head (4) or hub of a helicopter. The invention is achieved by that at least one sensor (9) is arranged to continuously measure the vertical angular movement (α) of a rotor blade and/or the flapping hinge (7).The invention also includes a method for monitoring the same movements.
Abstract(Chinese):

本发明涉及一种用于监视通过将铰链（7）附接到直升机的中心头部（4）或毂的附接的转子叶片的运动的系统。 本发明通过以下方式实现：至少一个传感器（9）布置成连续地测量转子叶片和/或摇动铰链（7）的垂直角运动（α）。本发明还包括一种用于监测相同运动 。
