Method for ventilating equipment e.g. accessory gearbox, of engine of double body and double flow aircraft, involves maintaining forced air circulating in ventilation circuit until temperature of equipment lowers to predetermined value

摘要

The method involves removing downstream air in a blower to pass an air through an air ventilation system to a space (26) in a turbojet engine during an operation of the turbojet engine, where an equipment (28) of the engine is arranged to discharge the air that is controlled by an air flow regulation valve. A forced air circulating in a ventilation circuit is maintained by activating a ventilator (36) until a temperature of the equipment lowers to a predetermined value after stopping the turbojet engine. An independent claim is also included for a turbojet engine comprising a ventilation circuit.
