Thrust reverser for a dual-flow turbine engine nacelle

摘要

The invention relates to a thrust reverser (1) for the nacelle of a dual-flow turbine engine, in which the bypass means (4) and the actuation jacks (22) of the sliding cowling (2) and of the reverse flaps (20) are arranged in two substantially parallel planes arranged above one another in the radial direction of the nacelle. The invention also relates to a nacelle for a dual-flow turbine engine that comprises such a thrust reverser.

主权项

1. A thrust reverser for a nacelle of a turbofan jet engine comprising:
an upstream structure, fixed diverting means attached to the fixed upstream structure, the diverting means being capable of diverting at least part of a cold air stream of a turbojet engine outside the nacelle, a sliding cowl sliding in translation in a direction substantially parallel to a longitudinal axis of the nacelle, a plurality of blocker doors including at least one driven blocker door and at least one driving blocker door pivot mounted at an upstream end on the sliding cowl, and the at least one driving blocker door being driven via at least one driving link, the sliding cowl being mobile via at least one actuating cylinder, and the at least one driving blocker door also being connected to the at least one actuating cylinder via the at least one driving link so that a movement in translation of the at least one actuating cylinder of the sliding cowl and of the at least one actuating cylinder of the at least one driving blocker door enable the sliding cowl to move alternatively from a closed position, in which the at least one driving blocker door is in stowed position and the sliding cowl ensures aerodynamic continuity of the nacelle by covering the diverting means, to an open position in which the sliding cowl opens a passageway in the nacelle by uncovering the diverting means and the at least one driving blocker door is in pivoted position blocking part of an annular bypass duct of the nacelle, wherein the diverting means and the at least one actuating cylinder are arranged in two substantially parallel planes one above the other in a radial direction of the nacelle, and the at least one driven blocker door is driven by one or both adjacent the at least one driving blocker door controlled by the at least one actuating cylinder; and wherein the driving of the at least one driven blocker door is obtained via a transmission link mounted on a side of the at least one driven blocker door and cooperating with an arm fixed onto the at least one driving blocking door.
