Abstract
A fuel system includes a main fuel pump sub-system (MFP) with an inlet for receiving a supply of fuel from an inlet line. The MFP has a main outlet line configured to supply fuel to a main fuel throttle valve assembly (MFTV), and a cross-over outlet line. An augmentor fuel pump sub-system (ABFP) has an inlet connected in fluid communication with the cross-over outlet line, and an outlet connected in fluid communication with a main augmentor supply line. A actuation fuel pump sub-system (AFP) has an inlet connected in fluid communication with a branch of the main outlet line, an outlet line with a first outlet line branch configured to connect to supply fuel to the MFTV, and a second outlet line branch configured to connect to supply fuel to an actuation system.
