Variable vane angular position sensor

摘要

A variable vane control system for use with a gas turbine engine (10) includes an actuator (44), a mechanical linkage assembly (46), and a vane position sensor (52,54). The gas turbine engine has a plurality of variable vanes (48,50) each having an airfoil disposed in a gas flow path of the gas turbine engine. The plurality of variable vanes includes a first variable vane. The mechanical linkage assembly operably connects the actuator (44) to at least the first variable vane. The vane position sensor (52,54) is connected to one of the first variable vane or a portion of the mechanical linkage assembly proximate the first variable vane for sensing angular position of the first variable vane.
