When a new electric fuel pump as described above is incorporated into an engine, it is necessary to carry out an application test in combination with an existing engine at the prototype stage. However, it is not possible to newly develop an engine electronic control device that performs extremely complicated control and a fuel control device that is also responsible for control other than fuel flow rate control for the engine application test of the electric fuel pump at the trial stage. It is hoped that it will be avoided.

It has an electric pump control unit that controls fuel supply to the engine combustor by the electric fuel pump based on the information related to the command value of the fuel supply acquired by the acquisition unit.

According to the above electric pump test system, the command information acquisition unit acquires information related to the command value of fuel supply to the engine combustor output from the engine electronic control device of the engine to the fuel control device. The electric pump control unit controls the fuel supply of the electric fuel pump based on the information. In this way, by acquiring the information output from the engine electronic control device to the fuel control device and controlling the electric fuel pump, it is possible to control the electric fuel without modifying the engine electronic control device. Fuel can be supplied to the engine combustor by the pump, and the engine application test of the electric fuel pump can be performed.

Here, the command information acquisition unit uses an external device to monitor the command value of fuel supply to the engine combustor output from the engine electronic control device to the fuel control device. The monitoring signal output from the control device can be acquired as information related to the command value of fuel supply to the engine combustor.

As described above, the monitoring signal regarding the command value of the fuel supply to the engine combustor output from the engine electronic control device to the fuel control device is the command value of the fuel supply to the engine combustor in the command information acquisition unit. By adopting the configuration to acquire the information related to However, it is possible to carry out an engine application test of an electric fuel pump.

According to the present invention, there is provided an electric pump test system capable of performing an engine application test of an electric fuel pump while suppressing modification on the engine side.

It is a figure explaining the schematic structure of the electric pump test system which concerns on one Embodiment of this invention. It is a figure which shows typically the structure of the main part of the electric pump test system.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a diagram illustrating a schematic configuration of an electric pump test system 1 according to an embodiment of the present invention. Further, FIG. 2 is a diagram schematically showing a configuration of a main part of the electric pump test system 1.

The electric pump test system 1 shown in FIGS. 1 and 2 is a device that performs an engine application test of an electric fuel pump for supplying fuel from a fuel tank to an engine combustor. In the engine application test, when fuel is supplied to the engine combustor using the electric fuel pump, the engine can be operated properly, or the electric fuel pump is used to properly supply the fuel to the engine combustor. It is a test conducted to confirm whether it can be done. Therefore, an actually operable engine is used for the engine application test of the electric fuel pump. Therefore, as shown in FIG. 1, the electric pump test system 1 is a system used in combination with the engine 2 used in the application test.

As shown in FIG. 1, the engine 2 includes a FADEC 21, a fuel control device 22, and an engine combustor 23. The overall control of fuel in the engine 2, such as fuel supply to the engine combustor 23, is performed by the engine electronic control unit (ECU) that controls the entire engine 2, and command signals to each device, etc. To send. In the case of an aircraft engine, the FADEC21 (Full Authority Digital Engine Control) shown in FIG. 1 is used as the engine electronic control unit. Further, the fuel flow rate is controlled by the fuel management unit 22 (FMU) based on the command from the engine electronic control device (FADEC21 in FIG. 1). Further, as shown in FIG. 1, a pump 24 may be provided to supply fuel to the fuel control device 22.

First, the supply of fuel to the engine combustor 23 during normal operation of the engine 2, that is, when the application test of the electric fuel pump is not performed will be described. During normal operation, in the engine 2, the fuel control device 22 controls the flow rate of supplying the fuel stored in the external fuel tank 30 to each mechanism in the engine 2 based on the command from the FADEC 21. ing. The fuel control device 22 generally controls the flow rate by changing the position of the measuring valve by keeping the differential pressure before and after the measuring valve constant by using an internal valve mechanism. The position of the measuring valve is controlled by the hydraulic servo mechanism. Therefore, the FADEC 21 controls the position of the metering valve of the fuel control device 22 by passing a drive current for controlling the metering valve to a hydraulic servo mechanism (not shown) included in the fuel control device 22. Therefore, this drive current corresponds to a signal indicating the speed of the measuring valve. Of the fuel supplied to the fuel control device 22, the fuel having a flow rate corresponding to the position of the measuring valve of the fuel control device 22 is supplied to the engine combustor 23 via the flow path L1 and burned. The fuel is supplied to the fuel control device 22 via the flow path L2 from the fuel tank 30 to the pump 31 (see FIG. 1) and the pump 24, and the flow path L3 from the pump 24 to the fuel control device 22. Further, the surplus portion of the fuel supplied to the fuel control device 22 is returned to the pump 24 via the flow path L4.

The fuel control device 22 supplies fuel to a mechanism other than the engine combustor 23, such as a hydraulic servo mechanism that controls the position of the measuring valve. The fuel control device 22 is responsible for controlling the fuel supply in the engine 2.

On the other hand, the electric fuel pump 40 to be tested will perform an engine application test while supplying fuel to the engine combustor 23 instead of the fuel control device 22. Also in the engine application test, the amount of fuel supplied to the engine combustor 23 needs to be controlled based on the command from FADEC 21. However, since the FADEC 21 is a device designed to operate appropriately with the fuel control device 22, it is appropriate to issue a command related to fuel supply to the electric fuel pump 40. Remodeling and development of new programs are required. Since the FADEC 21 is a device that performs overall control related to the engine 2, the internal configuration and the like are complicated. Therefore, it is considered that a huge development cost and a development period are required to develop the electric fuel pump 40 so that it can be applied. Be done. Further, when modifying the FADEC 21, it may be necessary to grasp the control logic, control parameters, etc. in the FADEC21, but the control logic, etc. in the FADEC21 cannot be easily grasped from the outside. In some cases, the cost may increase further. As described above, it is not preferable from the viewpoint of cost and the like to newly modify and develop the FADEC 21 for the engine application test of the electric fuel pump 40. Therefore, it is desirable to minimize modifications to the electric fuel pump 40 for performing an engine application test.

Similar to FADEC 21, it is desired that the fuel control device 22 be minimized in modification for conducting an engine application test of the electric fuel pump 40. When performing an engine application test of the electric fuel pump 40, the fuel control device 22 needs to supply fuel to the engine combustor 23 because the electric fuel pump 40 measures the fuel and supplies it to the engine combustor 23. Will disappear. However, the fuel control device 22 is also a device that supplies fuel (for example, servo fuel to a hydraulic servo mechanism or the like) used in each part of the engine other than the engine combustor 23. Fuel supply to other than the engine combustor 23 cannot be performed by the electric fuel pump 40 to be tested. Therefore, it is difficult to simply replace the fuel control device 22 with the electric fuel pump 40 to perform an engine application test.

In this way, when conducting an engine application test of the electric fuel pump 40, modifications on the engine 2 side are kept to a minimum, and essential changes such as changes in control logic or control parameters are kept to a minimum. It is desirable to keep it.

On the other hand, in the electric pump test system 1 according to the present embodiment, the electric fuel pump 40 is directed to the engine combustor 23 based on the command from the FADEC 21 while minimizing the modification of the FADEC 21 and the fuel control device 22. It makes it possible to supply fuel and facilitate engine application tests.

The configuration and function of the electric pump test system 1 will be described. As shown in FIG. 1, the electric pump test system 1 includes an electric pump test device 11, a flow rate control panel 12, and a motor controller 13. The flow rate control panel 12 corresponds to the command information acquisition unit 15 in FIG. Further, the motor controller 13 corresponds to the electric pump control unit 16 in FIG.

Further, the electric pump test system 1 includes a plurality of flow paths L11 to L14 and a cooler 51 as a configuration related to a fuel flow path connecting the fuel control device 22, the electric fuel pump 40, and the engine combustor 23. , A pressure valve 52, a back pressure adjusting valve 53, switching shutoff valves 54 and 55, a differential pressure sensor 56, a pressure gauge 57, and an electric valve controller 58. In FIG. 2, only the flow paths L11 to L13 are shown. Details of the flow paths L11 to L14 will be described later.

First, a schematic configuration of the electric pump test system 1 will be described with reference to FIG. First, the electric pump test device 11 is a device that acquires various information related to the engine application test of the electric fuel pump 40, collects and analyzes the test results, and the like. In the engine application test, it has a function of acquiring signals and the like output from the FADEC 21 of the engine 2 and also acquiring signals and the like output from various devices of the engine 2. The electric pump test device 11 includes, for example, a CPU (Central Processing Unit), RAM (Random Access Memory) and ROM (Read Only Memory) which are main storage devices, a communication module for communicating with other devices, and a hard disk. It is configured as a computer equipped with hardware such as an auxiliary storage device such as. Then, by operating these components, the function as the electric pump test device 11 is exhibited.

The command information acquisition unit 15 (flow control panel 12) has a function of acquiring information related to a fuel supply command value output from the FADEC 21 to the fuel control device 22.

Examples of the information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22 include a signal (measurement valve speed command) instructing the speed of the measuring valve with respect to the fuel control device 22. Further, the measuring valve position F / B (feedback) signal transmitted from the fuel control device 22 to the FADEC 21 also becomes information related to the command value of the fuel supply. This measuring valve position F / B signal corresponds to a signal indicating that control corresponding to the measuring valve speed command from FADEC 21 has been performed, and is a resolver signal for reading the measuring valve position. Further, at the time of the engine application test, the metering valve speed command from the FADEC 21 to the fuel control device 22 and / or the monitoring signal for monitoring the metering valve position F / B signal from the fuel control device 22 to the FADEC 21 is provided. It is sent to the electric pump test device 11. This signal also becomes information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22.

In the present embodiment, the command information acquisition unit 15 acquires the metering valve position F / B signal sent from the fuel control device 22 to the FADEC 21 and the monitoring signal sent from the FADEC 21 to the electric pump test device 11. .. Among the information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22, the information included in the monitoring signal sent from the FADEC 21 to the electric pump test device 11 is measured by the FADEC 21 with respect to the fuel control device 22. Since the information is related to the content specified by the valve speed command, it is appropriate as the information to be acquired by the command information acquisition unit 15. However, this signal is only a monitoring signal, and real-time performance is not guaranteed. Therefore, in some cases, missing data may occur. That is, there is a possibility that the command information acquisition unit 15 cannot acquire the information corresponding to the metering valve speed command transmitted from the FADEC 21 to the fuel control device 22 in real time. Therefore, the command information acquisition unit 15 also acquires the metering valve position F / B signal from the fuel control device 22 to the FADEC 21 and uses it as a backup. As a specific operation, for example, the command information acquisition unit 15 periodically acquires the monitoring signal from the FADEC 21 and the metering valve position F / B signal from the fuel control device 22, and monitors from the FADEC 21. If the signal cannot be acquired, the fuel supply command content may be determined by referring to the separately acquired metering valve position F / B signal from the fuel control device 22. Since the metering valve position F / B signal from the fuel control device 22 is an F / B signal corresponding to the metering valve speed command from the FADEC 21 to the fuel control device 22, a slight amount (for example, the drive time of the hydraulic servo mechanism) It is preferable to use it as a backup because the signal has a time lag (derived from). However, the method is not limited to the above operation example, and the method in which the command information acquisition unit 15 acquires information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22 and the operation method thereof are appropriately changed. ..

When the command information acquisition unit 15 acquires information related to the command value of fuel supply from the FADEC 21 to the fuel control device 22, the command information acquisition unit 15 issues a command (pump speed command) related to the pump speed of the electric fuel pump 40 based on the information. It is transmitted to the control unit 16. The pump speed command is information that specifies the driving speed (rotational speed) of the electric fuel pump corresponding to the amount of fuel transported. As a pump speed command for designating the drive speed of the pump, the signal from the FADEC 21 acquired by the command information acquisition unit 15 may be used (diverted) as it is, or may be compatible with the electric fuel pump 40 as needed. It may be configured to be rewritten into a signal.

The command information acquisition unit 15 includes, for example, a CPU (Central Processing Unit), RAM (Random Access Memory) and ROM (Read Only Memory) which are main storage devices, a communication module for communicating with other devices, and a hard disk. It is configured as a computer equipped with hardware such as an auxiliary storage device such as. Then, by operating these components, the function as the command information acquisition unit 15 is exhibited.

The electric pump control unit 16 has a function of controlling the electric fuel pump 40 based on a pump speed command from the command information acquisition unit 15. Specifically, the electric pump control unit 16 has a function of supplying a motor drive current for driving the electric fuel pump 40 based on a pump speed command to the electric fuel pump 40.

Under the control of the electric pump control unit 16, the electric fuel pump 40 operates by receiving the motor drive current, and the fuel supplied from the fuel tank 30 through the flow path L12 is supplied to the engine combustor 23 (via the flow path L13). (See Fig. 1). With such a configuration, the electric fuel pump 40 controls the flow rate of fuel based on the information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22, and delivers an appropriate amount of fuel to the engine combustor 23. Can be supplied.

As described above, the fuel control device 22 originally supplies fuel to the engine combustor 23 based on the metering valve speed command from the FADEC 21. In the electric pump test system 1 according to the present embodiment, the fuel control device 22 is based on the metering valve speed command from the FADEC 21 and other commands without modification or the like that partially restricts the operation of the fuel control device 22. Maintain the state of performing the conventional operation. Therefore, fuel is supplied from the fuel tank 30 to the fuel control device 22 via the flow path L2, and the fuel control device 22 discharges the fuel measured based on the metering valve speed command from the flow path L1. However, in the electric pump test system 1, the flow path L1 is not connected to the engine combustor 23, but is connected to the flow path L2 via the flow path L11 and the flow path L12 connected to the flow path L1. That is, a circulation flow path is formed by combining a part of each of the flow paths L2, L1, L11, and L12. Further, a part of the fuel branched from the above circulation flow path is supplied to the electric fuel pump 40. On the circulation flow path between the fuel tank 30 and the electric fuel pump 40, the moving direction of the fuel may change depending on the operating conditions of the fuel control device 22 and the electric fuel pump 40.

With reference to FIG. 1, a fuel flow path including the above-mentioned circulation flow path around the fuel control device 22 and the electric fuel pump 40 and each device provided around the fuel flow path will be described.

In FIG. 1, a flow rate control panel 12 is provided in place of the command information acquisition unit 15. The flow rate control panel 12 is configured to include a computer and a control board, and may have not only a function as a command information acquisition unit 15 but also a function of performing monitoring and the like related to the flow rate control. Further, in FIG. 1, a motor controller 13 is provided in place of the electric pump control unit 16. The motor controller 13 is a controller that controls the inverter and speed control, and has a function of controlling the electric fuel pump 40. Further, the F / B signal (F / B signal related to the rotation angle position of the motor) from the electric fuel pump 40 is acquired.

As described above, the fuel weighed by using the measuring valve in the fuel control device 22 is discharged from the flow path L1 toward the engine combustor 23. However, the flow path L1 is cut off in the middle, and the flow path L11 is attached. The flow path L11 is connected to the flow path L12 that connects the electric fuel pump 40 and the flow path L2 that is attached to the flow path L2 that connects the fuel tank 30 and the pump 24 of the engine 2. A back pressure adjusting valve 53 for adjusting the pressure of the fuel in the engine and a cooler 51 for cooling the fuel heated in the engine are provided on the flow path L11. The back pressure adjusting valve 53 is controlled by the electric valve controller 58 based on the internal pressure of the engine combustor 23 measured by the pressure gauge 57. When controlling the back pressure adjusting valve 53 by the electric valve controller 58, the flow is taken into consideration in consideration of the differential pressure in the fuel injection valve (not shown) in addition to the measured value in the pressure gauge 57 described above. The fuel pressure on road L1 is calculated, but is not limited to this method.

By pressurizing the fuel supplied from the fuel control device 22 to the flow path L1 by the back pressure adjusting valve 53, the pressure can be brought into the same state as in the normal operation of the engine 2. As a result, the pressure of the servo fuel supplied from the fuel control device 22 can be set to the same state as in the normal operation of the engine 2. Therefore, it is not necessary to modify the servo mechanism or the like when carrying out the engine application test.

Further, a pressurizing valve 52 and a switching shutoff valve 54 are provided between the electric fuel pump 40 and the engine combustor 23. The pressurizing valve 52 has a function of pressurizing the fuel from the electric fuel pump 40. A differential pressure sensor 56 is attached to the pressurizing valve 52, and an F / B signal related to the differential pressure of the fuel before and after pressurization measured by the differential pressure sensor 56 is sent to the flow control panel 12.

On the upstream side (fuel control device 22 side) of the back pressure adjusting valve 53 on the flow path L11, the flow path L14 connecting the flow path L11 and the flow path L13 (the engine combustor 23 side of the pressure valve 52) is connected. Is provided. The flow path L14 is a flow path for supplying fuel from the fuel control device 22 to the engine combustor 23 when the electric fuel pump 40 is not used. Switching between using the flow path L14 (whether to supply fuel from the fuel control device 22) or using the flow path L13 (whether to supply fuel from the electric fuel pump 40) is performed by the switching shutoff valve 54. , 55 is opened and closed.

As described above, in the electric pump test system 1 according to the present embodiment, the fuel supplied from the fuel control device 22 is discharged to the outside of the engine 2 via the flow path L1 and the flow path L11, and then the cooler. It is cooled at 51. Then, the cooled fuel is supplied to the electric fuel pump 40, or is returned to the fuel control device 22 via the flow path L12, the flow path L2, the pump 24, and the flow path L3. The fuel control device 22 measures the fuel based on the measuring valve speed command from the FADEC 21 and discharges the fuel to the passage L1 in the subsequent stage. Therefore, the FADEC 21 is operating in the same state as during normal engine operation.

On the other hand, the electric fuel pump 40 is measured by the control by the motor controller 13 based on the information related to the command value of the fuel supply from the FADEC 21 to the fuel control device 22 acquired by the flow rate control panel 12. The weighed fuel is pressurized by the pressurizing valve 52 provided in the flow path L13 and then supplied to the engine combustor 23. Therefore, during the engine application test of the electric fuel pump 40, the fuel is also weighed in the fuel control device 22, but the fuel weighed by the operation of the electric fuel pump 40 is supplied to the engine combustor 23. Will be.

As described above, according to the electric pump test system 1 according to the present embodiment, the FADEC 21 as the engine electronic control device of the engine 2 is output to the engine combustor 23 as the fuel control device 22 as the fuel control device. The command information acquisition unit 15 acquires information related to the fuel supply command value of the above, and the electric pump control unit 16 controls the fuel supply of the electric fuel pump 40 based on the information. In this way, by acquiring the information output from the FADEC 21 to the fuel control device 22 and controlling the electric fuel pump 40, the engine by the electric fuel pump 40 can be used without modifying the FADEC 21. Fuel can be supplied to the combustor 23, and an engine application test of the electric fuel pump 40 can be performed.

Further, according to the above configuration, the information output from the FADEC 21 to the fuel control device 22 during normal operation is acquired and used on the electric pump test system 1 side. Therefore, it is not necessary for the electric pump test system 1 to grasp the control logic, control parameters, and the like in the FADEC 21. Therefore, it is possible to reduce the modification of the engine 2 side when the engine application test of the electric fuel pump 40 is performed.

Further, in the electric pump test system 1, the command value of fuel supply to the engine combustor 23 output from the FADEC 21 to the fuel control device 22 is output to the electric pump test device 11 which is an external device. The monitoring signal is acquired by the command information acquisition unit 15 as information related to the command value of fuel supply to the engine combustor. With such a configuration, it is possible to control the electric fuel pump 40 by using the monitoring signal conventionally output from the FADEC 21, so that the electric fuel pump 40 can be further suppressed while the modification of the engine 2 side is further suppressed. It becomes possible to perform an engine application test of the fuel pump 40.

Further, in the electric pump test system 1, the feedback signal from the fuel control device 22 with respect to the command value of the fuel supply to the engine combustor 23 is commanded as backup information of the information related to the command value of the fuel supply to the engine combustor 23. It is acquired by the information acquisition unit 15. With such a configuration, even when the above-mentioned monitoring signal is not properly acquired by the command information acquisition unit 15, the electric fuel pump 40 can be controlled by using this feedback signal. Therefore, the engine application test of the electric fuel pump 40 can be performed more appropriately.

Further, when the electric pump test system 1 that suppresses the modification of the engine 2 side is configured, the fuel control device 22 is configured to discharge fuel based on the command value of the fuel supply from the FADEC 21 to the engine combustor 23. It is preferable to leave. However, in the engine application test, the fuel discharged from FADEC 21 is not supplied to the engine combustor 23, so it is necessary to take measures such as discharging it to the outside and discarding it. On the other hand, as described above, when the fuel control device 22 has a circulation flow path for returning the fuel supplied from the fuel control device 22 to the fuel control device 22, the fuel control device 22 starts from the fuel control device 22 based on the command value from the FADEC 21. Since the supplied fuel can be returned without being discarded, the fuel supplied from the fuel control device 22 can be effectively used when the system design suppresses the modification of the engine 2 side.

Further, in the electric pump test system 1, since the cooler 51 for cooling the fuel from the fuel control device 22 is provided in the flow path L11, when the fuel flowing in the engine 2 is discharged to the external flow path. Can be cooled properly.

The electric pump test system 1 according to the embodiment of the present invention has been described above, but the above-described embodiment shows an example of the present invention. The electric pump test system 1 according to the present invention is not limited to the above embodiment, and may be modified or applied to other things without changing the gist described in each claim.

For example, the command information acquisition unit 15 and the electric pump control unit 16 of the electric pump test system 1 may be realized by a combination of the flow rate control panel 12 and the motor controller 13 as described in the above embodiment. It may be realized in combination with the device of.

Further, the fuel flow path is not limited to the flow path described in the electric pump test system 1 described above, and can be appropriately changed. For example, the fuel circulation flow path supplied from the fuel control device 22 and the fuel flow path supplied to the electric fuel pump 40 may be independent of each other.

Further, in the above embodiment, the case where the engine application test of the electric fuel pump in the engine for an aircraft is performed has been described, but the electric pump test system 1 according to the present embodiment is also applied to an engine different from that for an aircraft. Can be done.
