Stall warning detector for gas turbine engine

摘要

A stall detector for a gas turbine engine is disclosed where detection is obtained by continuously monitoring turbine temperature and either compressor speed or bleed valve position and provide a stall signal solely when turbine temperature exceeds a predetermined value and the compressor speed decreases at a predetermined rate or when turbine temperature exceeds a predetermined value at the time that the compressor bleeds are in the opened position.
