DOUBLE-FLOW TURBOREACTOR CONTAINING A SERIES OF ROTATING BLADES TO CLOSE THE SECONDARY FLOW VEIN

摘要

The invention relates to a double-flow turbojet (100) with a nacelle (102) comprising a slide (218) movable in translation between an advanced position and a retracted position to open a window between a vein and the outside, a plurality of blades (250), each being movable in rotation on the slider (218) between a retracted position and a deployed position, and a maneuvering system (400) moving each blade (250) and comprising for each blade (250), a shaft (402) movable in rotation on the slide (218) and on which the blade (250) is fixed, and a toothed sector (406) fixed on the shaft (402), and a toothed arc (408) movable in rotation on the slide (218) about a longitudinal axis (X), where the teeth of the toothed arc (408) mesh with the teeth of each toothed sector ( 406), a carriage (510) movable in translation on the slide (218) in a plane pe rpendicular to the longitudinal axis between a first position and a second position, a connecting rod (512) mounted articulated between the carriage (510) and the toothed arc (408), a rib (502) integral with the fixed structure (206) , and a guide U (516) integral with the carriage (510) and which overlaps the rib (502). The use of rotating blades on the slide and the simplified maneuvering system makes the assembly lighter than the use of state-of-the-art reversal doors. Fig. 5
