Latest Patents

One of his latest patents is titled "Rotor arrangement for over tip leakage measurement using a multi-hole pressure probe." This invention features a rotor stage with an annular array of rotor blades, each equipped with a tip. The design includes a casing that surrounds the rotor stage, defining a clearance between the tips and the casing. Additionally, it incorporates an over tip leakage measurement system that utilizes a multi-hole total pressure probe, strategically mounted to a stationary component downstream of the rotor stage. The probe is aligned with the expected flow direction from the rotor stage, allowing for precise measurements.

Another notable patent is the "Clearance and wear determination apparatus." This apparatus is designed to determine the clearance between a moving member and a casing surface, particularly in gas turbine engines. It consists of a main waveguide and a reference element positioned between the proximal and distal ends of the waveguide. The transmitter/receiver transmits an electromagnetic signal through the waveguide and receives portions of the signal reflected from the reference element, casing surface, and the moving member. This allows for simultaneous determination of the relative positioning of these components.
