Actuation system for a propulsive unit of an airplane

摘要

The invention relates to an actuation system (100) for a propulsive unit including a nacelle, a turbojet engine, and an air circulation channel defined between the nacelle and the turbojet engine, the actuation system (100) including: a body and a connection device for attaching the body to the nacelle, the connection device enabling the body to move relative to the nacelle along two axes of rotation; a first member for moving a flap for controlling the airflow in the channel, the first member extending from the body and having a first point for attaching the first member to the flap; a second member for moving a thrust-reversing flap, the second member extending from the body and having a second point for attaching the second member to the flap, the body being arranged between the first and second attachment points; and a transmission device (40) having an input (42), a first output (44) connected to the first member (50), and a second output (43) connected to the second member (70), the transmission device (40) being capable of selectively transmitting input movement towards the first output, in order to move the flow-controlling flap, or towards the second output, in order to move the thrust-reversing flap.
