Abstract: An architecture for feeding fuel to a power plant (1) of a rotorcraft, which power plant comprises a plurality of engines (2, 3) individually fed with fuel by respective assemblies (4, 5). Each assembly (4, 5) comprises a fuel feed circuit (9, 10) for feeding a safe tank (6, 7) from a fuel tank (8) that is common to the assemblies (4, 5). Together the feed circuits (9, 10) form a circuit for forced both-way transfer of fuel from either one of the assemblies to the other via the common tank (8) and an intercommunication (21) interposed between the safe tanks (6, 7), which safe tanks are fitted with respective spillage devices (17, 18, 19, 20) for transferring excess fuel to the common tank (8).
