Description
Technical Field
[0001] The present invention relates to the technical field of monitoring the lubricating oil consumption rate of aircraft engines, and particularly to a method, device, equipment and medium for detecting the lubricating oil consumption rate of aircraft engines. Background Art
[0002] The lubricating oil consumption rate of an engine is an important indicator characterizing the health status of an aircraft engine. Each airline or operator of an aircraft has to establish a process to obtain, record this data and conduct continuous tracking and monitoring. In the civil aviation industry, for a long time, the processes of collecting, calculating, transmitting and entering into the database the data of the lubricating oil consumption amount and consumption rate of an engine are all carried out manually. The process is complex, with many links, the data is prone to errors and loss, and at the same time, it also increases the workload and pressure of maintenance personnel. With the continuous development of aircraft on-board equipment and communication technology, there is an increasingly strong call to automatically complete the calculation and transmission of the lubricating oil consumption rate data of an engine through on-board equipment.
[0003] In the prior art, during the process of automatically completing the calculation of the lubricating oil consumption rate data of an engine through on-board equipment, the lubricating oil amount before the aircraft takes off is directly compared with the lubricating oil amount after the aircraft lands. Since the engine is still in the operating state at this time, the influence of inconsistent engine operating conditions on the lubricating oil amount is not considered. This method makes the lubricating oil consumption rate data automatically calculated by the on-board equipment inaccurate.
[0004] Therefore, during the process of using on-board equipment to automatically complete the detection of the lubricating oil consumption rate data of an engine, how to improve the detection accuracy has become an urgent problem to be solved. Summary of the Invention

The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
[0024] To illustrate the technical solution of the present invention, it will be described below through specific embodiments.
[0025] See Figure 1 , which is a schematic flow chart of a method for detecting the lubricating oil consumption rate of an aircraft engine provided in the first embodiment of the present invention. As Figure 1 shown, the method for detecting the lubricating oil consumption rate of the aircraft engine may include the following steps.
[0026] S101: After the engine is started on the ground of the aircraft, determine whether the aircraft takes off according to the flight state of the aircraft in the current flight.
[0027] In step S101, when the aircraft starts the current flight, start the corresponding engine and determine whether the aircraft takes off according to the flight state of the aircraft in the current flight. Among them, the flight state of the aircraft includes a taxiing state and an air state. The taxiing state is the state where the aircraft starts to taxi on the ground, and the air state is the state where the aircraft is flying in the air. Determining whether the aircraft takes off means determining whether the aircraft enters the air.
[0028] Before taking off, the aircraft taxis on the airport runway, taxiway and apron. After the aircraft is pushed out of the parking position, it will move to the starting point of the designated runway through the taxiway of the airport under the guidance of the ground command or the airport tower.
[0029] In this embodiment, after the engine is started on the ground of the aircraft, determine whether the aircraft takes off according to the flight state of the aircraft in the current flight, that is, determine whether the aircraft enters the air. Obtain the flight state of the aircraft in the current flight. If the flight state in the current flight of the aircraft includes the corresponding air state, it is determined that the aircraft takes off, so as to calculate the corresponding lubricating oil consumption rate during the flight when the aircraft takes off. If the flight state in the current flight of the aircraft does not include the corresponding air state, it is determined that the aircraft does not take off.
[0030] Optionally, determining whether the aircraft takes off according to the flight state of the aircraft in the current flight includes: If the flight state changes from the taxiing state to the air state, or the flight state changes from the air state to the taxiing state, it is determined that the aircraft takes off; If the flight state does not change from the taxiing state to the air state, it is determined that the aircraft does not take off.
[0031] In this embodiment, it is determined whether the aircraft has taken off by judging whether the flight state has been converted. If the flight state changes from the taxiing state to the airborne state, or from the airborne state to the taxiing state, it is determined that the aircraft has taken off. Among them, when changing from the taxiing state to the airborne state, it means that the aircraft enters the air from the ground; when changing from the airborne state to the taxiing state, it means that the aircraft enters the ground from the air. When the aircraft enters the air from the ground or enters the ground from the air, it can be determined that the aircraft has completed the current flight.
[0032] If the flight state does not change from the taxiing state to the airborne state, it is determined that the aircraft has not taken off. That is, the aircraft has not entered the air from the ground, and the aircraft has not completed the current flight. This is to prevent calculating the corresponding lubricating oil consumption rate when the aircraft has not completed the current flight.
[0033] S102: If the aircraft has taken off, determine the current start time and current end time of the current flight according to the preset rules.
[0034] In step S102, if the aircraft has taken off, determine the current start time and current end time of the current flight according to the preset rules. Among them, the preset rules are the rules for determining the current start time and current end time of the current flight set in advance. The current start time is the start time of taxiing for the current flight, and the current end time is the time when the engine shuts down after the current flight is completed.
[0035] In this embodiment, if the aircraft has taken off, determine the current start time and current end time of the current flight according to the preset rules. When determining the current start time, the time corresponding to when the aircraft enters the taxiing state can be used as the current start time. When determining the current end time, the time when the engine changes from the running state to the shutdown state after the flight state changes from the airborne state to the taxiing state can be determined as the current end time.
[0036] It should be noted that when determining the current start time and current end time of the current flight, the corresponding current start time and current end time are recorded through the on-board ACMS (Aircraft Condition Monitoring System) system. The on-board ACMS system can receive data sent from other on-board computers or sensors, which is convenient for determining the corresponding flight time according to the current start time and current end time when calculating the lubricating oil consumption rate.
[0037] In this embodiment, if the aircraft has taken off, determine the current start time and current end time of the current flight. The purpose is to determine the time when the lubricating oil starts to be consumed and the time when the consumption ends when calculating the lubricating oil rate.
[0038] Optionally, according to a preset rule, determine the current start time and the current end time of the current flight, including: Determine the time when the aircraft enters the taxiing state as the current start time of the current flight; After the flight state changes from the airborne state to the taxiing state, determine the time when the engine state changes from the running state to the shutdown state as the current end time of the current flight.
[0039] In this embodiment, the corresponding time is determined based on the flight state of the aircraft and the engine state of the engine, so that the current start time and the current end time are associated with the flight state of the aircraft and the engine state, ensuring the accuracy of the determination of the remaining amount of lubricating oil after flight, improving the accuracy of determining the start time when the lubricating oil starts to be consumed and the stop time when the lubricating oil stops being consumed, and thus improving the accuracy of detecting the lubricating oil consumption rate.
[0040] In this embodiment, the flight state includes the taxiing state and the airborne state, and the engine state includes the running state and the shutdown state. After the aircraft completes the engine start on the ground, determine the time when the aircraft enters the taxiing state as the current start time, that is, use the time when the aircraft starts to taxi as the start time of the engine operation, ensuring the accuracy of the start time for detecting the lubricating oil consumption in the current flight, and avoiding calculating the lubricating oil consumption when the engine is started but not taking off into the lubricating oil consumption of the current flight. For example, in cases such as ground testing of the engine and the aircraft taxiing out and then taxiing back, the aircraft has not started the current flight, and it is not necessary to calculate the corresponding lubricating oil consumption into the lubricating oil consumption of the current flight, improving the accuracy of determining the start time for detecting the lubricating oil consumption.
[0041] After the aircraft changes from the taxiing state to the airborne state and then from the airborne state back to the taxiing state, determine the time when the engine changes from the running state to the shutdown state as the current end time. Among them, determining that the aircraft changes from the taxiing state to the airborne state and then from the airborne state back to the taxiing state is to determine the takeoff of the aircraft and prevent the current end time from being determined when the engine is started but not taking off. After the aircraft changes from the taxiing state to the airborne state and then from the airborne state back to the taxiing state, determine the time when the engine changes from the running state to the shutdown state as the current end time, that is, the end time of the lubricating oil consumption.
[0042] In this embodiment, determine the time when the aircraft enters the taxiing state as the current start time of the engine operation in the current flight, and determine the time when the engine changes from the running state to the shutdown state as the current end time of the engine operation, that is, use the time when the engine starts to work and the time when it ends working in the current flight as the current start time and the current end time, so as to facilitate the correspondence between the time period between the current start time and the current end time and the lubricating oil consumption time period, and improve the accuracy of determining the time period for detecting the lubricating oil consumption.
[0043] S103: Determine the lubricating oil quantity when the engine has just shut down as the target remaining quantity of lubricating oil after the current flight.
[0044] In step S103, determine the lubricating oil quantity when the engine has just shut down as the target remaining quantity of lubricating oil after the current flight, where the target remaining quantity of lubricating oil after the current flight is the remaining quantity of lubricating oil in the engine lubricating oil tank after the current flight.
[0045] In this embodiment, after the aircraft stops taxiing, the lubricating oil quantity when the engine has just shut down can be determined as the target remaining quantity of lubricating oil after the current flight, so as to determine the consumption of lubricating oil during the current flight of the aircraft according to the target remaining quantity.
[0046] It should be noted that when obtaining the target remaining quantity, it can be obtained according to the corresponding on-board ACMS system. The on-board ACMS system can receive data sent from other on-board computers or sensors. When calculating the lubricating oil consumption rate, obtain the lubricating oil quantity when the engine has just shut down, so as to determine the lubricating oil quantity when the engine has just shut down as the target remaining quantity of lubricating oil after the current flight.
[0047] In this embodiment, determining the lubricating oil quantity when the engine has just shut down as the target remaining quantity of lubricating oil after the current flight can prevent the lubricating oil that continues to be consumed when the engine is still running after the aircraft lands from not being included in the lubricating oil consumption during the current flight, resulting in inaccurate lubricating oil consumption.
[0048] S104: Obtain the initial quantity of lubricating oil for the current flight. According to the current start time, current end time, target remaining quantity of lubricating oil, and initial quantity of lubricating oil, calculate the lubricating oil consumption rate of the engine for the current flight.
[0049] In step S104, obtain the initial quantity of lubricating oil for the current flight. According to the current start time, current end time, target remaining quantity, and initial quantity of lubricating oil, calculate the lubricating oil consumption rate of the engine for the current flight. Among them, according to the current start time and current end time, calculate the working duration of the engine during the flight of the aircraft. According to the target remaining quantity and the initial quantity of lubricating oil, calculate the consumption of lubricating oil for the current flight. According to the consumption of lubricating oil for the current flight and the working duration of the engine, calculate the lubricating oil consumption rate of the engine for the current flight.
[0050] In this embodiment, the initial amount of lubricating oil for the current aircraft flight is obtained. According to the current start time and the current end time, the working duration of the engine during the aircraft flight is calculated, that is, according to the difference between the current start time and the current end time, the working duration of the engine during the aircraft flight is determined. According to the target remaining amount and the initial amount of lubricating oil, the consumption of lubricating oil for the current flight is calculated, that is, according to the difference between the target remaining amount and the initial amount of lubricating oil, the consumption of lubricating oil for the current flight is determined. According to the ratio of the consumption amount to the duration, the lubricating oil consumption rate of the engine for the current flight is calculated.
[0051] It should be noted that when calculating the working duration of the engine during the aircraft flight according to the current start time and the current end time, since there may be time differences in different regions, the current start time and the current end time are subjected to time unification processing, that is, the current start time and the current end time are converted to the timekeeping in the same region (generally Coordinated Universal Time - UTC).
[0052] It should be noted that when calculating the lubricating oil consumption rate of the engine for the current flight according to the current start time, the current end time, the target remaining amount of lubricating oil and the initial amount of lubricating oil, it can be calculated according to the corresponding on-board ACMS system. The on-board ACMS system can receive data sent by other on-board computers or sensors, and calculate the lubricating oil consumption rate of the engine for the current flight according to the obtained current start time, current end time, target remaining amount of lubricating oil and initial amount of lubricating oil.
[0053] In this embodiment, by calculating the lubricating oil consumption rate of the engine for the current flight according to the current start time, the current end time, the target remaining amount of lubricating oil and the initial amount of lubricating oil, the problem of incomparable lubricating oil amounts caused by inconsistent engine operating conditions is excluded, the accuracy of obtaining the lubricating oil consumption is improved, and thus the accuracy of calculating the lubricating oil consumption rate is improved.
[0054] Before obtaining the initial amount of lubricating oil for the current flight, it further includes: Before the aircraft takes off, the target remaining amount of lubricating oil after the previous flight is used as the initial amount of lubricating oil before the current flight, and the engine status is continuously monitored. If the engine enters the operating state and then returns to the shutdown state again, the lubricating oil amount at the moment when the engine is just shut down each time is updated as the initial amount of lubricating oil before the flight.
[0055] In this embodiment, before obtaining the initial amount of lubricating oil for the current flight, first obtain the initial amount of lubricating oil before the current flight, so as to determine the initial amount of lubricating oil for the current flight based on the initial amount of lubricating oil before the current flight. Continuously monitor the engine status. If the engine enters the operating state and then returns to the shutdown state again, update the lubricating oil amount at the moment when the engine just shuts down each time to the initial amount of lubricating oil before the flight. That is, before the aircraft takes off, if the engine starts, update the initial amount of lubricating oil before the current flight, so that when determining the initial amount of lubricating oil for the current flight based on the initial amount of lubricating oil before the current flight, an accurate initial amount of lubricating oil before the flight can be obtained, and thus an accurate initial amount of lubricating oil for the current flight can be obtained.
[0056] It should be noted that after obtaining the initial amount of lubricating oil before the current flight, it is recorded in the on-board ACMS system. The on-board ACMS system can receive data sent by other on-board computers or sensors. The on-board ACMS system receives the initial amount of lubricating oil before the current flight and updates the initial amount of lubricating oil before the flight according to the engine status.
[0057] Optionally, before obtaining the initial amount of lubricating oil for the current flight, it further includes: Before the aircraft takes off, continuously monitor the change in the lubricating oil amount when the engine is in the shutdown state. If the lubricating oil amount rises by more than a certain degree when the engine is in the shutdown state, continuously record the maximum value of the lubricating oil amount during the engine shutdown period, and update the maximum value of the lubricating oil amount to the initial amount of lubricating oil before the flight.
[0058] In this embodiment, before the aircraft takes off, continuously monitor the change in the lubricating oil amount when the engine is in the shutdown state. If the lubricating oil amount rises by more than a certain degree when the engine is in the shutdown state, it is considered that the engine has replenished lubricating oil. Then continuously record the maximum value of the lubricating oil amount during the engine shutdown period, and update the maximum value of the lubricating oil amount to the initial amount of lubricating oil before the flight. Among them, the lubricating oil amount rising by more than a certain degree means that the increase amount exceeds the preset threshold based on the initial amount of lubricating oil. That is, during the engine shutdown period, when the lubricating oil amount rises by more than the preset threshold, continuously record the maximum value of the lubricating oil amount during the engine shutdown period. That is, when the lubricating oil amount stops rising, update the maximum value of the lubricating oil amount to the initial amount of lubricating oil before the flight.
[0059] In this embodiment, during the engine shutdown period, when the lubricating oil amount before the flight rises, continuously record the maximum value of the lubricating oil amount during the engine shutdown period, so as to update the maximum value of the lubricating oil amount to the initial amount of lubricating oil before the flight and ensure the accuracy of the initial amount of lubricating oil before the flight.
[0060] Optionally, obtaining the initial amount of lubricating oil for the current flight includes: Determine the initial amount of lubricating oil for the current flight as the last updated initial amount of lubricating oil before the flight, which is used to calculate the lubricating oil consumption rate of the engine after the current flight ends.
[0061] In this embodiment, before the current flight, if the lubricating oil quantity is continuously updated, such as when the engine enters the operating state multiple times and then returns to the shutdown state again, or lubricating oil is replenished to the engine, record the initial quantity of lubricating oil after each update, and determine the initial quantity of lubricating oil before the current flight at the last update as the initial quantity of lubricating oil for the current flight, which is used to calculate the lubricating oil consumption rate of the engine after the current flight ends.
[0062] In this embodiment, determine the initial quantity of lubricating oil before the current flight at the last update as the initial quantity of lubricating oil for the current flight. If the initial quantity of lubricating oil before the current flight at the last update is the quantity of lubricating oil after the engine enters the operating state and then returns to the shutdown state again, it can prevent the lubricating oil consumption before the aircraft flight from being included in the lubricating oil consumption during the current flight. If the initial quantity of lubricating oil before the current flight at the last update is the maximum value of the quantity of lubricating oil when the quantity of lubricating oil in the shutdown state of the engine rises beyond a certain level, it can prevent the situation where the calculated lubricating oil consumption during the current flight is less than the actual lubricating oil consumption during the current flight.
[0063] In this application, according to the flight state and engine state of the current aircraft flight, determine the current start time and current end time of the current flight. Uniformly determine the target remaining quantity of lubricating oil after the current flight when the engine has just shut down, and clarify the time reference and engine state for determining the remaining quantity of lubricating oil, so as to facilitate comparing the target remaining quantity of lubricating oil with the initial quantity before the current flight to determine the lubricating oil consumption, eliminating the problem of incomparable lubricating oil quantities caused by inconsistent engine operating conditions, improving the accuracy of obtaining the lubricating oil consumption, and thus improving the accuracy of calculating the lubricating oil consumption rate.
