Fuel supply system comprising a centrifugal main fuel pump.

摘要

A high speed centrifugal fuel pump (34) delivers fuel to the main metering valve (12) of a fuel control (10) of a gas turbine engine (13) for feeding the engine's burners, and a boost pump (30) and positive displacement pump (32) pressurize fuel for the servo medium for actuating the various valves actuators (14) and engine geometry actuators (18). The boost pump (30) also assures that the vapor/liquid flow relationship satisfies the engine's requirements.
