Gas turbine control system especially for aircraft - has manual emergency control in event of automatic control failure

The control system regulates the fuel delivery volume to the combustion chamber and the jet cross section variation in order to hold the combustion gas temperature at a safe value before entering the turbine. The control system has a section which responds to the manual emergency control unit to ope...

Beschreibung
Zusammenfassung:	The control system regulates the fuel delivery volume to the combustion chamber and the jet cross section variation in order to hold the combustion gas temperature at a safe value before entering the turbine. The control system has a section which responds to the manual emergency control unit to open the jet cross section to its maximum value in order to keep the combustion gas temperature at the turbine entrance at a safe value. The manual emergency control is provided with a valve to feed a working pressure to a coupling to connect the hand control, which is normally unconnected, to the fuel supply regulator. A pressure sensitive servo is also connected to the valve to actuate the jet flaps.
