Abstract
Description
Claims (1)
- 피치변경 동작방식으로 날개(20)를 구동시키기 위한 상호관련되고 하나의 날개(20)에 연결된 다수의 유압액튜에이터(15)를 구비한 다수의 날개(20)의 피치를 조절하기 위한 피치작동시스템에 있어서, 입력신호에 반응하여 유압액튜에이터(15)에 유체를 공급하는 다수의 피이드백 제어부재(40)와 제1의 유압공급원에 연결된 입력부재(35) 사이에서 유체가 통하게 함으로써 유압액튜에이터(15)가 작동되게 하고, 입력부재(35)와 피이드백 제어부재(40)를 통해서 유입된 유압에 의해 유압액튜에이터(15)가 작동하여 피이드백 제어부재(40)의 위치를 입력부재(35)와 통하지 않게 함으로써 제어밸브(30)를 작용하지 않게 하며, 소정의 날개피치의 설정치를 유지하도록 유압액튜에이터(15)의 동작을 억제시키는 제어밸브(30)를 구비하게 된 것을 특징으로 하는 날개피치 작동시스템.
