Definitions
- the present invention relates to the diagnosis of an aircraft engine computer, and in particular of the main control computer of this engine.
- the technical background includes in particular documents FRA1 -3 078 791 , US-A1 -6,442,498, EP-A1 -3 614 154 and US-A1 -4,567,756.
- An aircraft engine such as a turbomachine, is equipped with an engine control computer.
- This main engine computer also called the DE ⁇ U computer (acronym for the English Digital Engine Control Unit) must be tested during regular maintenance operations to ensure that it is fully functional and does not show any failure. It can be likened to the brain of the engine so its proper functioning is essential to the functioning and operability of the aircraft engine.
- diagnostics are carried out.
- the purpose of diagnostics is to test the computer in order to identify potential faults or failures.
- test bench the computer must be dismantled and removed from the engine then installed on the test bench to carry out the tests of several functions of the computer.
- a test bench is relatively heavy because it weighs several hundred kilograms and is also fragile. It is therefore not easily transportable and is generally kept in the workshop where the diagnosis is carried out.
- the test bench has several functions:
- the failures can come from the computer or from the elements connected to this computer, such as harnesses or equipment.
- the equipment is for example sensors or actuators.
- One solution to lighten a diagnostic device would be to limit its functions. For example, a device whose main function would be to detect certain computer failures could be less bulky and lighter than a test bench of the aforementioned type.
- the problem with such a diagnostic device would remain its electrical connection to the computer and to the elements to be tested. Indeed, to carry out the tests, it would be necessary to connect the device to the computer and to the elements which have numerous and different connectors. It would therefore be necessary to have several different means of connection and to connect and disconnect the connectors according to the tests to be carried out, which would be long and tedious.
- the device would be equipped with numerous connection ports and would therefore have to be oversized to have, for example, all these ports on one and the same face of the device.
- the connection means would connect the device to the computer and to the equipment and would be so numerous that they would risk becoming entangled and hampering the maintenance operation.
- the diagnosis is carried out by connecting a diagnostic tool in the cockpit of the aircraft, one engine of which is equipped with the computer to be tested.
- the advantage of this approach is that engine removal is not required.
- this approach has drawbacks in particular because it makes it possible to identify a failure, but not to identify the source of the failure. After identifying a failure, it is therefore necessary to investigate to find the origin of the failure (of the computer or of one of the elements connected to the computer) knowing that the failure could be linked to an operating problem. or communication between two elements. It is therefore necessary to carry out numerous tests to check the various possible failures, some tests requiring the removal and replacement of equipment by another equivalent.
- Removing equipment is a complex operation because dismantled and tested equipment must be rechecked before being reassembled on the aircraft. Disassembled and tested equipment may in fact be fully functional. The search for faults therefore leads to the dismantling and reassembly of numerous items of equipment, which results in an increased risk of diagnostic errors and in a long and costly maintenance operation.
- NFF National Framework for Inspection
- a final approach consists in carrying out manual measurements on engine components attached to the aircraft, but this approach does not allow automatic diagnosis to be carried out.
- the invention relates to a diagnostic device for an aircraft engine computer, this device comprising:
- this unit being autonomous and mobile and being configured to carry out:
- connection means configured to connect the unit to a computer of an aircraft engine, characterized in that the connection means comprise a single connection cable which comprises at one end a first connection to the unit and at an opposite end several second plugs for connection to the computer and/or to elements of the aircraft engine intended to be connected to the unit.
- an autonomous diagnostic unit a unit configured to carry out tests on its own and to identify faults according to the results of these tests, and therefore to establish a state of health of the computer and/or the elements to which (s) it is connected;
- this device is for example equipped with at least one electrical supply battery;
- a mobile unit a unit easily transportable by a user, that is to say whose weight and dimensions mean that the unit can be lifted and moved by the user, from a storage place to the foot of the aircraft for a maintenance operation
- the invention thus proposes a single cable for connecting the device and the unit to the computer, which simplifies and accelerates the maintenance operation of the computer. There is no longer any risk of using a bad means of connection or a means of connection equipped with bad plugs. Furthermore, the fact of having a single plug on one side of the cable makes it possible to ensure polarization and therefore to avoid inverted cable assembly during connections.
- the same cable could be connected to the unit when performing both types of tests (continuity/insulation and integrity check). Or a single first cable could be plugged into the unit when performing continuity/insulation testing and a second single cable could be plugged into the same unit when performing integrity verification tests.
- the cables would then advantageously be keyed mechanically and/or could integrate an internal electrical keying system which would be detected by the unit to carry out one or other of the tests.
- the device according to the invention may comprise one or more of the following characteristics, considered independently of each other or in combination with each other:
- the cable comprises a first section with a single branch and a second section with several parallel branches, the branch of the first section being equipped with the first plug at its end opposite the second section, and the branches of the second section being equipped with second plugs at their ends opposite the first section;
- the first section has a length L1 and the second section has a maximum length L2, L1>k.L2 with k at least equal to 1 and preferably at least equal to 2;
- At least some of the branches of the second section have different lengths
- the device further comprises a portable computer system, the unit and this computer system being configured to communicate by wireless link;
- the second plugs of the cable comprise plugs which are configured to be connected to ports of the computer, and other plugs which are configured to be connected to complementary plugs of harnesses or equipment of the aircraft engine;
- the unit is configured to measure electrical impedance values, to compare measured values with theoretical values prerecorded in the unit, and to emit a signal according to the results of the comparison;
- the unit comprises a signal generation module, a signal acquisition module, a data generation module, a data acquisition module, at least one data storage memory, a data processing module , a data communication module, etc. ;
- the unit is in the form of a suitcase with a closing lid and at least one carrying handle.
- the present invention also relates to a use of a device according to one of the preceding embodiments for the diagnosis of a computer of an engine which is attached to an aircraft.
- the engine is a propulsion unit equipped with a nacelle and the computer is located in the nacelle.
- the computer is a FADEC3 or a DE ⁇ U.
- the invention relates to a method for diagnosing an aircraft engine computer, by means of a diagnostic device comprising:
- this unit being autonomous and mobile and configured to carry out automatic tests of continuity and/or electrical insulation of electrical connectors, and to determine a state of health of these connectors according to the results of the tests, and
- connection means configured to connect the unit to a computer of an aircraft engine, characterized in that the method is carried out when the engine is attached to the aircraft and comprises the steps of:
- the method therefore makes it possible to check the state of health of the harnesses and of the equipment, such as the actuators and the sensors, connected to the computer. This verification is carried out by testing electrical continuity and electrical insulation of connectors.
- one strand of an electrical harness bundle is connected at its ends to connectors and must ensure electrical continuity between these connectors.
- An electrical continuity test between these connectors should make it possible to verify this continuity and therefore that the strand is not interrupted or broken.
- one strand of this bundle must be electrically isolated from another strand of this bundle.
- Connectors connected to the ends of these strands must therefore be electrically isolated from each other.
- An electrical insulation test between these connectors should make it possible to check this insulation and therefore the absence of a short circuit between the strands.
- the method according to the invention may comprise one or more of the following characteristics and/or steps, considered independently of each other or in combination with each other:
- the equipment includes actuators and/or sensors
- each of the tests consists of measuring an impedance value, comparing this measured value with a theoretical value pre-recorded in the unit, and emitting a signal according to the results of the comparison;
- connection means to a single port on the unit and to the harness and equipment plugs, these connection means comprising a ground connection connected to a metal casing of the motor;
- connection means comprise a single connection cable which comprises at one end a first plug for connection to the unit and at an opposite end several second plugs for connection to the harness and to the equipment.
- the invention relates to a method for diagnosing an aircraft engine computer, by means of a diagnostic device comprising:
- this unit being autonomous and mobile and configured to carry out automatic tests to verify the internal electrical integrity of a computer without simulating the flight conditions of the engine to which the computer is connected,
- connection means configured to connect the unit to a computer of an aircraft engine, characterized in that the method is carried out when the engine is attached to the aircraft and comprises the steps of:
- connection of the connection means to the unit on the one hand and to the computer on the other hand, and - analyze the internal electrical integrity of the computer by carrying out automatic tests including:
- the principle is not to read the self-test faults or to read the faults reported during operation but to specifically excite the computer in order to compare its operation with a model. If its functioning deviates from the model then it is declared non-functional.
- the unit will make it possible to carry out internal checks in the computer by proceeding to the excitation of the inputs and outputs of the computer by passing adjustment parameters into the internal memories of the computer, and internal measurement which will check the responses according to the excitations.
- the unit will then check that the returns comply with the expected or the expected.
- the invention therefore does not electrically simulate all of the sensors and actuators but intervenes directly in the computer to check the integrity of its operation as closely as possible to the computer.
- This allows the device to be compact and therefore to be mobile in order to be transported as close as possible to an engine and to be able to carry out a maintenance operation directly on the computer of an engine attached to the aircraft.

- connection means 28 to the single port of the unit 26 and to the plugs of the harness 22 and/or of the equipment (actuators 20 and sensors 22), as shown schematically in FIG. .
- the tests are performed automatically by automatically switching between the different electrical connectors of the harnesses/sensors/actuators whose continuity is to be tested. This switching is programmed and the measurements made are impedances which must conform to tables of theoretical values programmed according to what is tested.
- the unit tests all the connectors that normally come from the harnesses/sensors/actuators that plug into the ECU by connecting them to this unit instead.
- the measurements are then automated, they only take a few seconds per measurement without risk of false manipulation that could distort the measurement as when it is done manually with a multimeter and an aircraft mechanic.
- the invention therefore makes it possible to overcome false manipulation, increases the reliability of the measurement and also accelerates the process by automating the measurements once the harnesses/sensors/actuators are connected to the unit by the connection means.
- the measured continuity is actually an impedance which results in voltage, current and/or resistance measurements in the unit.
- connection means 28 are connected to the single port of the unit 26 and plugs of the harness 22 and / or equipment (actuators 20 and sensors 22 ), these connection means 28 comprising a ground connection 42 connected to a metal casing of the motor, such as the aforementioned casing 14.
- each insulation test is also carried out as it could be done manually and pin to pin on each of the equipment connectors and/or harnesses connected to the computer, but the invention proposes to do it directly and automatically.
- the unit then automatically switches between the different electrical connectors of the harnesses/sensors/actuators whose insulation must be tested. This switching is programmed in the unit and the measurements made are impedances which must return to conform to tables of theoretical values programmed according to what is being tested.
- the unit tests all the connectors which are normally coming from the sensors/actuators and which plug into the ECU by connecting them to this unit instead.
- the measurements are then automated, they only take a few seconds per measurement without risk of false manipulation that could distort the measurement as when it is done manually with a multimeter and an aircraft mechanic.

- the tests comprise two distinct verification phases, a first phase of verification of the electrical integrity of the computer via the input ports, and a second phase of verification of the electrical integrity of the computer via said at least one output port.
- the first phase comprises the transmission of the adjustment parameters to the computer 16 via the input ports 16a, and the measurement of signals generated directly in the internal memories of the computer and in software interfacing between the operating system and all the computer application software.
- the unit injects defined signals via the cable to simulate the physical quantities of the sensors/actuators to be tested and checks that the regulation functions expected according to the simulated inputs comply with those expected.
- the measurements made in the computer are made internally at the level of the internal feedback of the signals. These tests use the simulation of the external parts connected to the computer but the measurements are carried out internally by internal feedback of the measurements directly at the level of the memory registers and the software interfacing between the operating system and all the computer application software. A real state of correct internal operation (or malfunction) of the computer is thus obtained.
- false failure inhibition can be caused by the current/voltage/impedance sweep of the physical quantities expected by the computer. This restores the computer to the same state as before the test.
- the second phase comprises the transmission of adjustment parameters to the computer via said at least one output port, and the measurement of signals generated directly in the internal memories of the computer and in software interfacing between the operating system and all of the computer's application software.
- the output tests use the same principle as the input tests.
- the unit injects defined signals via the cable to simulate the physical quantities of the sensors/actuators to be tested and checks that the regulation functions expected according to the simulated outputs comply with those expected.
- the measurements made in the computer are made internally at the level of the internal feedback of the signals. These tests use the simulation of the external parts connected to the computer but the measurements are carried out internally by internal feedback of the measurements directly at the level of the memory registers and the software interfacing between the operating system and all the computer application software. A real state of correct internal operation (or malfunction) of the computer is thus obtained.
- false failure inhibition can be caused by the current/voltage/impedance sweep of the physical quantities expected by the computer. This restores the computer to the same state as before the test.
