Movable bonnet actuating and controlling system for jet engine nacelle of aircraft, has electronic control unit for controlling locking unit and actuator along predetermined actuating sequence, and actuator for driving bonnet of nacelle

摘要

The system has an electromechanical actuator (2) for driving a movable bonnet (1) of a nacelle of a jet engine, and a centralized electronic control unit (15) for controlling an electrically controlled locking unit (4) and the actuator along a predetermined actuating sequence. The locking unit locks the bonnet in a closed position. A detection unit i.e. sensor (9), detects a locked or unlocked state of the locking unit, where the detection unit returns information to the control unit for processing and/or displaying the information. The control unit is integrated to the actuator. An independent claim is also included for a jet engine nacelle comprising an air inlet structure to canalize airflow to a fan of a jet engine.
