Definitions
- the invention relates to an engine control system for a jet engine for propeller aircraft for controlling actuated by actuators injection, boost pressure, Com monrailtik- and propeller control valves comprising a plurality of sensors and a control device connected to these and the actuators.
- the invention is therefore based on the object to provide a simple design, redundant control for the non-redundant actuators of the control valves of aircraft diesel engines, which ensures safe operation of the engine even when errors occur.
- an engine control system for a propeller aircraft diesel engine for controlling the injection, boost pressure, common rail pressure and propeller control valves actuated by non-redundant actuators which comprises a plurality of sensors and a control device connected to these and the actuators, two are connected to the sensors ver - Bound and respectively connected to a first and to a second power supply - first and second - engine governor provided, which are connected to each other via a serial bus and - via the - with the first engine controller powered with voltage - relays are optionally connectable to the actuators, the two
- Engine governors each have a diagnostic function that calculates the health levels (A and B) determined by the detected failures that are interchangeable with the serial bus and that are compared.
- the power supply to the relay is interrupted, so that the second engine controller is automatically connected via the fallen relay to the actuators and thus a redundant Engine control system for a jet diesel engine is present.
- the essence of the invention lies in the automatically switchable connection of the two engine controllers communicating with each other via relays as a function of the calculated health level.
- Engine governor fails or the first engine controller is defective, the second engine controller is automatically activated. An error at the output of one engine governor will not affect the other engine governor as they are never directly connected. In addition, a failure results in most failure modes a relay does not cause a complete engine failure. For example, the relay in question turns off at one turn and the output concerned is driven by the other engine controller. If a relay contact is high-impedance, it will probably be a contact of the normally active first engine controller. Then the control can still be done via the second engine controller.
- the aircraft diesel engine important, redundant sensors and less important, not redundant sensors are assigned.
- the relays are connected via a manually operable switch, wherein the switching to the second engine controller by the pilot by manual interruption of the power supply is feasible. That is, the pilot can also force a switch to the second engine governor because of the non-100% fault detection by the engine control system.
- a warning lamp for signaling a non-maximum health level is connected to both engine controller.
- the intended for communication between the two engine controllers serial bus is preferably a CAN bus.
- the diagnostic function of the first and second engine controllers includes detecting errors and calculating the health level based on the transmitted errors, the errors being weighted differently according to their importance to engine operation.
- the health-level errors typically include short circuits, faulty sensors, over-voltage, over-speed, over-high or low-level Rail or boost pressure, missing serial communication or the like ..
- the engine control system comprises two full-digital - first and second engine controllers 1 (FADEC A) and 2 (FADEC B) which are known from aviation under the name FADEC (Füll Authority Digital Engine Control) and are therefore not described here in more detail.
- plate 3 are connected to each other and with a aircraft diesel engine 4 and which are each connected to a power supply 21, 22.
- the aircraft diesel engine has four injection valves 5 to 8 and a wastegate 9, a rail pressure control valve 10 and a Propellerregelven- valve 11, which are each assigned to operate non-redundant actuators 5 'to 11'.
- the aircraft diesel engine 4 furthermore has a plurality of sensors 12, which are important for engine operation and therefore redundant, (for example rotational speed, power specification and the like) and also less important and therefore not redundant sensors 13.
- the terminals 12 'and 13' of the redundant and non-redundant sensors 12, 13 are connected to respective terminals 12 '', 13 '' of the two engine controllers 1 and 2 (FADEC A and FADEC B).
- the actuators 5 'to 11' provided for valve adjustment are each connected via a control line to a relay 14 to 20 on the connecting plate 3.
- the relay '14 to 20 are connected via a manually operable switch 23 to the engine controller 1.
- each control valve connections 5 '' to 8 '' for controlling the actuators 5 'to 8' the injection valves 5 to 8 via the relay 14 to 17 and control valve connections 9 '' to H '' for controlling the actuators 9 'to 11' of the wastegate 9, the rail pressure control valve 10 and the propeller control valve 11 via the relay 18, 19 and 20 are provided.
- each engine controller 1 or 2 each have two terminals 21 'and 22' to the power supply 21 and 22 and one terminal 24 ', 25' to a warning lamp 24 and 25, respectively.
- a relay connection 23 'for the connection via the switch 23 with the relay 14 to 20 is still provided on the engine controller 1.
- a serial bus 26 here a CAN bus, and corresponding bus connections to the respective engine controllers 1 and 2.
- FADEC A and FADEC B are present, which can communicate with each other via the serial bus 26 and of which one is active and the relays 14-20 on the connecting plate 3 with the actuators 5 'to 11' for arranged on the aircraft diesel engine 4 valves (5 to 11) is connected to control these.
- the two engine controls 1 and 2 have internal diagnostic functions that include, for example, short circuit detection at the outputs (ports), overvoltage detection, faulty sensors, overspeed, over or under boost or rail pressure, missing serial communication, and other faults.
- the diagnostic functions calculate one each so-called health level A or B, in which the possible errors are weighted differently. This means that, for example, the failure of a less important sensor leads to a smaller drop in the respective health level than the failure of an important sensor or the occurrence of a short circuit.
- the two engine controllers 1 and 2 communicate with each other via the serial bus 26.
- Engine Governor 1 also includes a comparator that compares the two calculated health levels A and B with each other.
- Health level B of the engine controller 2 has a value higher than the health level A, the relays 14 to 20 are turned off, so that - as shown in the drawing - the engine controller 2 (FADEC B) has control over the Actuators 5 'to 11' has.
- the warning lamp 24 or 25 connected to each engine controller 1 and 2
- failure to reach the maximum health level A or B is signaled.
- the pilot has the switch 23 also has the ability to interrupt the connection of the relay 14 to 20 with the engine controller 1 and thus manually switch the relay 14 to 20 to the engine controller 2.
- the relays 14 to 20 fall off and the engine controller 2 is automatically activated. Even with a defect of the engine controller 1, the engine controller 2 is automatically active due to the relay is not turned on. LIST OF REFERENCE NUMBERS
