Rotor tip stall prevention device of gas turbine

摘要

Disclosed is a rotor tip stall preventing device of a gas turbine. The rotor tip stall prevention device of the disclosed gas turbine is installed in the casing of the compressor and is connected to a pressure supply means for applying pressure to drive gas having a low molecular weight of high temperature and a driven gas having a high molecular weight of low temperature, and the driving gas and driven gas. Shock wave tube comprising a die frame for separating the; Quick response opening valve installed in the rotor blade side direction of the shock wave tube; And a sensor unit spaced apart from the quick response opening valve at a predetermined interval to be installed in close proximity to the rotor blade, and detecting the stall of the rotor blade to operate the quick reaction opening valve. Characterized in that it has been provided has the advantage of preventing the rotor tip of the gas turbine stall.
