FIELD: engines and pumps.
SUBSTANCE: invention relates to aircraft engineering, particularly, to turbojet nacelles. Claimed nacelle comprises rear section and moving element. Rear section encircles the engine compartment downstream part to confine, along with the nozzle, the engine compartment vent discharge opening cross-section. Said moving element is connected with at least one appropriate control member to displace between diverted position and working position. At diverted position, cross-section of said vent discharge opening is at maximum while moving element at working position decreases, at least partially, said cross-section. Aforesaid control member drives said moving element between diverted position and working position.
EFFECT: vent discharge opening can adapt to most probable in-flight conditions and pressure variations.
