Gas turbine vane body with instrumentation

An instrumented vane body is provided that includes a suction side and pressure side outer walls, an interior cavity, at least one supply conduit, a plurality of sensors, and a plurality of sensor ports. The suction and pressure side outer walls extend chordwise between leading and trailing edges and between inner and outer radial ends. The supply conduit is in fluid communication with the interior cavity, and is in communication with the interior cavity through at least one of the inner or outer radial ends. The sensor ports are disposed in the leading edge and each is configured to receive a sensor, and are spaced apart from one another. Each sensor port is in fluid communication with at least one vent aperture, and each is configured to permit core gas to enter that sensor part and exit the vane body through the at least one vent aperture.
