  • Proximity vane angle measurement
    Patent number: 11021991
    Abstract: A measurement system for determining an angular position of a component of a gas turbine engine includes one or more proximity sensors positioned at a fixed structure of the gas turbine engine and one or more sensor targets positioned at a rotatable component of the gas turbine engine. Each sensor target of the one or more sensor targets includes a target surface having a variable distance between the target surface and the proximity sensor with rotation of the rotatable component about a component axis of rotation. A measurement of distance between the proximity sensor and the target surface as measured by the proximity sensor is indicative of an angular position of the rotatable component relative to the component axis of rotation.

  • Systems and methods for variable alignment aerodynamic probes
    Patent number: 10704413
    Abstract: A variable alignment aerodynamic probe may comprise a probe body having a leading edge and extending radially into a vane case, a sensor element proximate the leading edge, and a bearing coupled to the probe body and the vane case. The probe body may be configured to rotate in response to a turned flow within the vane case. The rotation of the probe body may be configured to maintain an angle of attack of the leading edge with respect to the turned flow between 0° and 15°.
