A high response air angle probe to measure a flow direction in an air flow near or above Mach one. The probe is rotatably secured within an assembly with marking to indicate when a desired position of the probe within the air flow has been found. The probe includes a row of three high response pressure transducers on a leading edge region to detect when the probe is at a certain position within the air flow.

High response air angle probe

An inlet case for a small gas turbine engine, where the inlet case is formed as a hybrid piece with a metallic inner shroud cylinder and plastic guide vanes and plastic outer shroud molded around the metallic inner shroud cylinder. The metallic inner shroud cylinder carries an electric generator and provides for a good convective heat transfer surface to carry heat away from the electric generator and into the inlet air flow entering the engine. The plastic guide vanes and outer shroud allow for a light weight inlet case assembly that is also much easier to form the airfoil shapes than a machined metallic inlet case. The plastic guide vanes and outer shroud are injection molded around the metallic inner shroud cylinder to produce a rigid single inlet case. The metallic cylinder includes axial extending slots that receive the lower ends of the guide vanes during the injection molding process.
