Abstract: A turbofan having a nacelle comprising a slider being mobile in translation between an advanced position and a retracted position to open a window between a duct and the exterior, a plurality of blades, each one being mobile in rotation on the slider between a stowed position and a deployed position, and a maneuvering system that moves each blade. The maneuvering system comprises, for each blade, a shaft being mobile in rotation on the slider and on which the blade is fixed, a toothed sector being fixed to the shaft, a toothed arc being mobile in rotation on the slider, and having a bearing face, a threaded rod mounted fixed on the fixed structure, a cam having a tapped hole screwed onto the threaded rod and mounted fixed in translation with respect to the slider, and a return arrangement that presses the bearing face against the cam outer surface.
