Title: Iurii Kondrashev: Gas Turbine Sensor and Probe-Fixing Innovations.
Introduction
Iurii Kondrashev is an inventor associated with Gimhae, South Korea, and Doosan Enerbility Co., Ltd. His patent work focuses on components for gas turbines, including systems for sensing blade-tip clearance and securing blade vibration probes. He is credited with 2 patents in the information provided.
Latest Patents
Kondrashev’s listed patents address sensor installation and probe stability in gas turbine environments.
- Blade tip clearance sensor and gas turbine including same. This invention describes a sensor assembly mounted to a ring segment on a turbine casing. A bushing, washer, flange, spacer, and locking screw hold the sensor probe in position, while the probe measures clearance near a turbine blade. The design provides a structured mounting arrangement for the sensor and its cable.
- BTT probe fixing apparatus and gas turbine including same. This invention uses a cooling sleeve and probe holder to secure a blade tip timing (BTT) probe that measures blade vibration. The sleeve is fastened to a vane carrier, while the holder accommodates the sleeve and can move with casing thermal expansion. This arrangement is designed to keep the probe in a stable position relative to the vane carrier.
Career Highlights
Kondrashev’s listed inventions concern practical challenges in turbine monitoring, including sensor mounting, probe positioning, and operation amid thermal expansion. Both patents describe apparatuses intended for use in gas turbines.
