Control system for a jacket blower - a gas turbine engine

摘要

If the fan 12 of a ducted fan gas turbine engine 10 is damaged, the power output of the engine 10 may not be sufficient for a given throttle setting. The present invention provides a control system 24 which detects fan damage and ensures that there is sufficient fuel flow to the engine 10 to ensure that the overall engine power output is consistent with that commanded by the throttle setting.
