Abstract: A system for protecting against a short circuit, including a main branch and a secondary branch having a fuse, the system including a pyrotechnic actuator having a gas generator and a piston movable between an initial position and a final position, the system being configured to occupy the following positions: a passive position; and an active position, wherein the secondary branch includes a movable slide which is rigidly connected to one end of the fuse and is capable of being translated by the piston when the system moves from its passive position to its active position, the system being configured so that the slide causes the fuse to break after the main branch has opened when the system moves from its passive position to its active position.

Abstract: The invention relates to a hybrid propulsion architecture (100) for an aircraft, comprising: —a first source (102) of a first energy type, —second sources (104) of a second energy type different from the first energy type, —electrical propulsion systems (106), —an electric power supply network (118) connecting the first and second sources (102, 104) to the electrical propulsion systems, such that each electrical propulsion system is powered by the first source and by one of the second sources, the architecture being characterised in that it further comprises: —means for segregating (120) the electrical propulsion systems, which means are arranged in the electric power supply network and configured to impose a direction of flow of the electric power from the first source to the electrical propulsion systems.
