Abstract
A system includes an actuation pump sub-system (APS). A fuel oil cooler (FOC) is included in a first branch of a supply line. The FOC is in fluid communication to receive flow from a second outlet of the APS. The APS includes a bypass valve (BPV) in a second branch of the supply line, in parallel with the FOC and in fluid communication to allow flow from the third outlet into the supply line bypassing the FOC. A combined main and augmentor pump sub-system (CMAPS) has a main inlet connected in fluid communication with the supply line downstream of the BPV and FOC, a gas generator (GG) outlet for supplying fuel to a downstream gas generator, and an augmentor outlet for supplying fuel to a downstream augmentor.
