Abstract

Variable guide vanes(VGVs) that consist of link mechanisms and an actuator system are required for an aircraft gas turbine engine to adjust the incidence angle of stator vanes. In this study, we developed a VGV actuator system for three-stage VGVs with two hydraulic actuators. The requirements for the actuator system were derived by analyzing the link mechanisms and air loads, and a hydraulic power-pack was developed based on these requirements. Through a load test using the actuator test-rig and the application of synchronizing control logic with proper control gains, the actuator system could be developed and verified.

가스터빈 압축기의 가변정익은 다수의 정익을 동시에 회전시킬 수 있도록 하는 가변정익 링크메커니즘과 이를 동작시키는 구동시스템으로 구성된다. 본 연구에서는 총 3단으로 구성된 가변정익을 2개의 유압구동기로 작동시킬 수 있는 가변정익 구동시스템을 개발하였다. 가변정익의 공력하중과 링크메커니즘 기구분석을 통해 구동기의 요구 성능을 도출하고, 파워팩을 포함한 유압구동시스템을 개발하였다. 부하 시험장치를 이용하여 개발한 구동기의 성능을 평가하였으며, 최적의 제어 이득과 동기제어로직을 적용하여 항공용 가스터빈 시험을 위한 가변정익 구동시스템을 개발 완료하였다.
