Abstract: In combination a blade clearance sensor and a radial flow separation wall of a gas turbine engine is provided. The blade clearance sensor is embedded in the radial flow separation wall. The radial flow separation wall comprising: a splitter hoop located radially outward from blades in a first flow path of the gas turbine engine, the splitter hoop being about concentric to a blade path of the blades; and one or more guide vane bases attached to a guide vane located radially outward from the splitter hoop in a second flow path, each of the one or more guide vane bases being securely attached to a radially outward surface of the splitter hoop, wherein the blade clearance sensor is configured to detect a blade clearance between the blades and the splitter hoop.

Abstract: A disclosed probe assembly includes a sensor member and an outer holder including a main bore for the sensor member, the outer holder including a first coefficient of thermal expansion. The sensor member is held within a sensor bore of an inner holder. The inner holder is held within the main bore of the outer holder by an interference fit. The inner holder includes a second coefficient of thermal expansion greater than the first coefficient of thermal expansion. Expansion of the inner holder is constrained by the outer holder to maintain the sensor member within the probe bore of the inner holder at elevated temperatures.

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°.
