Definitions
- the invention relates to the field of the maintenance of a system of actuators of a turbine engine on an aircraft, and more particularly to a system and a method for diagnosing a failure of such a system, in particular of a reversing system of thrust.
- the actuator system can also be a landing gear actuation system, a cargo door actuation system, a flap or control surface actuation system, etc.
- TSM diagnosis of abnormalities
- the TSM is therefore too complex and requires the removal of components to detect failures and this induces a lot of unjustified removals to detect, confirm or invalidate failures.
- the invention aims to provide a solution for diagnosing faults on a system of electromechanical or hydromechanical actuators of a turbomachine of an aircraft that is less time-consuming than the TSM and more targeted.
- An object of the invention proposes an electronic device for diagnosing the state of an actuator system of a turbomachine of an aircraft, the device being configured to be coupled to an electrical connection harness of a turbomachine connecting a computer of a turbomachine to a system of actuators of said turbomachine, the device comprising a power supply unit for supplying said device, a connection block configured to allow the connection of said device to the electrical connection harness of the turbomachine to be diagnosed , a communication block configured to deliver information to a user and receive instructions from the user, and a control block comprising a module for transmitting test signals and modules for measuring the signals received by the device in response to the test signals during an operating cycle of the turbomachine actuator system.
- the power supply module can comprise a battery configured to power the electronic device autonomously.
- the selection 220 of the test operation is conditioned by the failure messages previously recorded by the aircraft computer during the flight and received in the previous step, and from the messages coming from the maintenance center and collected by the operator as well than the criteria which cannot be recorded electrically by the electromechanical actuator system but which can be measured manually by the operator when the aircraft is on the ground, for example, a cowling misalignment with respect to another in the case of a thrust reverser.
