发明名称 NACELLE FOR AN AIRCRAFT TURBOJET ENGINE COMPRISING A SECONDARY NOZZLE SECTION WITH ROTARY DOORS
摘要 The present disclosure relates to a turbojet engine nacelle having an external cowling with an internal wall defining, with an internal fixed structure, an annular flow channel for a secondary airflow and an exhaust nozzle for said secondary airflow. The nozzle includes at least one opening, at least one continuous downstream end portion, downstream of said opening, and at least one door moving between a closed position and an open position allowing the passage of a part of said airflow through said opening. The nacelle is notable in that it includes a shaped device for activation of the door, during their activation from a closed position to an open position of the door, to drive the door in a combined movement that is translational in the direction running upstream from the nacelle and rotary towards the exterior of the nacelle.

主权项 1. A nacelle for an aircraft turbojet engine comprising: an inner fixed structure defining at least partially a fairing of the turbojet engine; an outer cowling comprising an upstream section and a downstream section, said downstream section comprising an outer wall and an inner wall defining, with the inner fixed structure, an annular flow channel of a secondary air flow, said downstream section comprising an ejection nozzle of said secondary air flow, said nozzle comprising: at least one opening in the downstream section of the outer cowling;at least one continuous downstream end portion, downstream of said at least one opening;at least one door alternately movable, upon activation of an actuating device, between a closed position sealing said opening and providing aerodynamic continuity of the nacelle, and an open position allowing passage of at least one portion of the secondary air flow through said at least one opening, from the annular flow channel towards an outside of the nacelle, wherein the actuating device is shaped, upon activation of said device from a closed position to an open position of the at least one door, in order to drive said at least one door into a combined movement in translation upstream of the nacelle and in rotation outwardly of the nacelle, and in that the actuating device comprises: at least one actuator comprising an upstream body secured to a fixed portion of the nacelle, and a rod having one end directly connected to an upstream wall of said at least one door; andat least one connecting rod having an end connected to the outer cowling of the nacelle and another end of which is connected to the at least one door of the nozzle.
