<p>To provide an aircraft pilot with an early and accurate warning of a nonrecoverable rotating stall in a gas turbine engine, a warning system detects engine speed and the gas stream temperature downstream of the combustor, calculates the ratio of speed to temperature, and signals the pilot when the ratio decreases to a predetermined fixed value which, for the engine being monitored, is indicative of a nonrecoverable stall. <IMAGE></p> |
