Using of autodyne transceiver modules on Gunn diodes for determination of turbomachine blades deformations

The levels of mechanical deformations of dynamically loaded blades in modern turbomachines in great extent define durability and reliability of gas-turbine engines. The report materials present the radar method and device for control of dynamic blades characteristics of gas-turbine engines (GTE). Primary converters with autodyne transceiver modules based on Gunn diodes are used in the discrete-phase method (DPM) equipment. The block diagram of the measuring setup and results of experimental studies are given.
