Latest Patents

Choi’s listed patents address blade measurement and sensor installation in gas turbines.

“Blade tip clearance sensor and gas turbine including same” describes a sensor assembly designed to measure the clearance between a turbine blade and its surrounding structure. The assembly uses a bushing, washer, flange, sensor probe, spacer, and locking screw to secure the probe to a ring segment mounted on the turbine casing.

“BTT probe fixing apparatus and gas turbine including same” concerns a system for holding a blade tip timing (BTT) probe, which measures blade vibration. A cooling sleeve accommodates the probe, while a probe holder allows the sleeve to slide as the casing expands with heat. The arrangement is designed to keep the probe positioned relative to the vane carrier during thermal expansion.
