ABSTRACT:
A fuel control unit forms part of a control system of a gas turbine aeroengine. The control unit is in communication with a main fuel line leading to the aeroengine and comprises a fuel accumulator, i.e. volume varied by free piston, which is controllable by the control system to take fuel from the fuel line to reduce temporarily but substantially the mass flow of fuel to the aeroengine. This is helpful in combating surge conditions in the aeroengine caused by temporary overfueling of the aeroengine by the fuel control system.
