The invention relates to a module () for recovery of energy of an aircraft cabin () comprising at least one air outlet () from the cabin and at least one fresh air inlet () into the cabin, the said module comprising: a turbine engine () comprising a compressor () and a turbine () mechanically coupled to one another; a cabin-air recovery duct () designed to be able to link the air outlet () from the cabin and the said turbine (); a cabin-air injection duct () designed to be able to link the compressor () and fresh air inlet () into the cabin; an emergency duct () designed to be able to link a high-pressure air source and the said turbine (); a control unit () configured to be able, according to predetermined operational conditions, to activate either a routine mode, in which the said turbine () is exclusively supplied by the air evacuated from the cabin (), or an emergency mode, in which the said turbine () is exclusively supplied by the air provided by the high-pressure air source.

Autonomous aircraft cabin energy recovery module and corresponding method

The invention relates to a system for environmental control of an aircraft cabin (), comprising a device for bleeding compressed air from at least one aircraft engine; an air cycle turbine engine () comprising at least one supercharger () connected to said device for bleeding compressed air by an air bleed duct () and a turbine () connected to the cabin () by a cabin inlet duct () in order to be able to supply said cabin with air at a controlled pressure and temperature, characterised in that it further comprises: stationary blading () which has a variable injection cross section and is mounted on said turbine () of said air cycle turbine engine () so as to be able to modify, on command, the flow rate and/or the pressure of air supplying an air inlet of said turbine (); and a second supercharger () which is mounted on said air cycle turbine engine () and is connected to a device for bleeding outside air and to said bleed duct.

Ventilation system for a fuel tank comprising a pump, an active liquid/vapor separator (LVS) that can be drained using the pump, in which a roll-over valve (ROV) that is normally open brings, by default, the internal volume of the LVS into communication with the pump and only blocks this communication when the level of fuel in the valve reaches a certain height or when the tank is tilted beyond a certain angle, or even overturned.
