DEVICE TO DETECT GAS TURBINE SHAFT FAILURE AND GAS TURBINE Russian patent published in 2009 - IPC F01D21/04 

FIELD: engines and pumps.

SUBSTANCE: device serves to detect aircraft gas first medium-pressure turbine shaft. Low-pressure turbine is arranged downstream of gas flow behind the former medium-pressure turbine. Propose device comprises control element arranged between first turbine rotor and second turbine stator and transfer element moving inside second turbine stator to transfer motion of control element, caused by shaft failure, to switching element arranged radially outside gas turbine flow passage and on turbine housing.

EFFECT: higher reliability of detecting gas turbine shaft failure.
