Abstract: A propulsion assembly with an outer compartment, an inner compartment, a supply pipe and a transfer pipe between the two compartments, a suction system between the two pipes, a regulating element that regulates the flow rate of air in the suction system and a fire-fighting system having a reservoir of extinguishing fluid, a discharge pipe connected to the reservoir, and a control system between the reservoir and the discharge pipe. The discharge pipe is configured and arranged to supply the transfer pipe when the control system is in the open position. The outside air is then driven by the suction system and passes through the two compartments in a forced manner and the extinguishing fluid reaches the transfer pipe to flow into the inner compartment.

Abstract: A propulsion assembly with a primary duct and a secondary duct, an outer fairing delimiting an outer compartment with an inlet opening, an inner fairing delimiting an inner compartment with an air exhaust aperture, a suction system having an inlet, an outlet and mobile elements that draw the air in via the inlet and deliver the air via the outlet, a drive that drives the mobile elements, a transfer pipe connected to the outlet, a distribution pipe disposed in the inner compartment, connected to the transfer pipe and having nozzles, a supply pipe that opens into the outer compartment and is connected to the inlet, and a regulator that regulates the flow rate of air in the suction system. The outside air is then driven by the suction system and passes through the two compartments in a forced manner.

Abstract: A system for protecting a thermocouple placed in an environment comprising at least one radiative element, comprising a plate positioned between the thermocouple and the radiative element. The plate has an overall surface condition of an internal face facing towards the thermocouple such that the internal face absorbs radiation coming from the radiative element more than the internal face reflects the radiation.

Abstract: A thermal protection device for equipment positioned in an engine compartment of an aircraft turbomachine is disclosed. The device comprises at least one heat shield arranged at least partially between the equipment and a thermally radiative wall of the engine compartment exposed to a heating source. The heat shield comprises an air-channeling elements connected to a cooling air source and configured to direct cooling air toward the equipment.

Abstract: A thermal protection device for equipment (14) positioned in an engine compartment (9) of an aircraft turbomachine comprises at least one heat shield (16) arranged at least partially between said equipment and a thermally radiative wall (12) of said engine compartment exposed to a heating source. Said shield (16; 26; 36) comprises air-channeling means (16a, 19) connected to a cooling air source (11) and configured to direct said cooling air toward said equipment (14).

Abstract: The overpressure door, of axial type, includes a hatch configured to pivot about an axis between a closed position and an open position and an aerodynamic appendage securely attached to the hatch. The aerodynamic appendage makes it possible to produce a deflection of the external flow in the open position of the hatch of the door.

Abstract: A ventilation device for a compartment, preferably a compartment of an aircraft engine, the device including an air intake adapted to capture a flow of air outside the compartment, an air diffuser adapted to guide the air flow into the compartment, and an air distributor adapted to distribute the air flow within the compartment, the air distributor in this device being separated from the air diffuser, and being placed inside the compartment at a distance from the air diffuser
