FIELD: aviation.
SUBSTANCE: invention relates to power units of an aerial vehicle. The power unit of an aerial vehicle includes a nacelle (2) with a turbojet engine (8) supported by a pylon (3), and a ventilation apparatus (13). The nacelle (2) comprises an outer fairing (9), an inner fixed structure (4) defining, together with the outer fairing (9), an annular space (6) wherein a cold air flow (7) can circulate, and a sealing gasket (10) located between the inner fixed structure (4) and the pylon (3). The sealing gasket (10) is intended for separating the cold area (11) of the pylon from the hot area (12) of the engine. The ventilation apparatus (13) is configured to deflect part (14) of cold air from the cold air flow (7) to the sealing gasket (10) for ventilation thereof.
EFFECT: increase in the productivity of the gasket at high temperatures for a longer time is achieved.
