Abstract
A movable vane control system is disclosed for use with a gas turbine engine having a turbine axis of rotation. The system includes a plurality of rotatable turbine vanes in a gas flow path within a turbine case of the gas turbine engine. A first vane position sensor having a first distance sensor is configured to sense the distance between the first distance sensor and a surface portion of a first of said plurality of vanes or a first movable target connected to the first vane. Additionally, the first distance sensor, the first vane surface portion, the first movable target, or a combination thereof is configured to provide a variable distance between the first distance sensor and the first vane surface portion or first movable target that varies as a function of a position of the first vane.
