Dynamic strain and temperature measurement of aero-engine turbine blade
Abstract
The paper deals with experiments in which free-filament type strain gauges were used to measure the dynamic strains in turbine blades. Using these high-temperature gauges, it proved possible to measure strains in disks and blades at temperatures of 750 C and accelerations of 39,000 g.
