Abstract
The present invention relates to a cryogenic fuel supply assembly (5) for an aircraft engine (1), comprising: - a cryogenic pipeline (7), in which the cryogenic fuel is liquid in a first operating mode and is vaporized in a second operating mode, - at least one heating installation (9) comprising an arm (25), from which extends a forearm (27) movable between a first position and a second position, the arm (25) being subjected to a heat input, in the first position, the forearm (27) being distant from the cryogenic pipeline (7), in the second position, the forearm (27) being in thermal conduction with the cryogenic pipeline (7) to create a thermal bridge between the cryogenic pipeline (7) and the arm (25).The invention also relates to an aircraft engine (1) equipped with such an assembly (5), an aircraft equipped with such an aircraft engine (1), and a method for maintaining such an assembly (5).
