An aircraft with a fuselage that accommodates a floor panel and a fuel storage system, wherein the fuel storage system comprises a tank system with at least one main tank 5a that is arranged underneath the floor panel; a cross ventilation system with a plurality of ventilation lines for venting the tank system, wherein the plurality of ventilation lines comprises at least one crossing ventilation line 11a that is routed from a first lateral side of the tank system to an opposite second lateral side of the tank system; and wherein the at least one crossing ventilation line is routed underneath or in the floor panel from the first lateral side of the tank system to the second lateral side of the tank system.

The invention relates to a device for the rapid reactivation of a helicopter turbine engine (6), characterised in that it comprises a pneumatic turbine (7) mechanically connected to said turbine engine (6) so as to be able to rotate it and ensure reactivation thereof; a pneumatic storage (9) connected to said pneumatic turbine (7) by means of a pneumatic circuit (10) for supplying pressurised gas to said pneumatic turbine (7); a controlled fast-opening pneumatic valve (11) arranged on the pneumatic circuit (10) between said storage (9) and said pneumatic turbine (7) and suitable for being on demand placed at least in an open position in which the gas can supply said pneumatic turbine (7), or in a closed position in which said pneumatic turbine (7) is no longer supplied with pressurised gas.

A vent valve includes a vent body including an outlet and at least one inlet, a main chamber, a main closable device movable from an open position to allow fluidic communication between the main chamber and the outlet, to a closed position to block fluidic communication between the main chamber and the outlet, and a first tubing having a first end and a second end, the first end connected to a first inlet, the second end spaced from the vent body, the first tubing further including a first closable device adjacent the second end. The first closable device allows fluidic communication between an exterior of the first tubing and an interior of the first tubing in a first orientation of the vent valve, and blocks fluidic communication between the exterior of the first tubing and the interior of the first tubing in a second orientation of the vent valve.

A power supply system includes: a first power supply circuit for supplying, to a first load device, direct current electric power output from a first power generation device; and a second power supply circuit for supplying, to a second load device, direct current electric power output from a second power generation device. In a case where the electric power output from the second power generation device is supplied to the first load device, a control device connects the first power supply circuit and the second power supply circuit to each other after suppressing the power consumption of the first load device and increasing the power consumption of the second load device.

In the case that an electrical power output from an external charging device is required to be supplied to a first electrical power storage device and a second electrical power storage device, and a difference between a voltage of the first electrical power supply circuit and a voltage of the second electrical power supply circuit is greater than or equal to a predetermined first voltage threshold value, then an electrical power supply system connects the first electrical power supply circuit and the second electrical power supply circuit after executing a precharging control in which the first electrical power storage device is charged by the electrical power output from the first electrical power generating device, and the second electrical power storage device is charged by the electrical power output from the second electrical power generating device.
