Super contingency aircraft engine control.

摘要

A fuel control (23) for an aircraft engine (10) employs super contingency logic (76) in response to low rotor speed of a helicopter (130) engine failure (131) or entry into an avoid region of a flight regime following engine failure (133) to after (161, 166-189) limits on the gas generator (30) of a free turbine gas engine (10), whereby following engine failure or in periods of extreme power need. risk of stressing an engine to its failure point is undertaken in favor of acquiring enough power to avoid a certain crash.
