[0023] The technical scheme in the embodiment of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.
[0025] The flight profile takes the takeoff base as the origin and consists of several flight phases, such as takeoff, climb, cruise, descent, approach and landing. The takeoff profile can represent the stage when the aircraft takes off. Takeoff usually consists of four stages. Different stages have different requirements for climb gradients. The crew needs to change the thrust and pitch control methods according to the stage the aircraft is in, and perform climb or acceleration operations. This involves the operation of flight guidance mode, automatic throttle mode, and speed target selection, etc. This makes the crew busier during the takeoff process, and incorrect operations may occur, increasing the safety risks of the aircraft.
[0026] In addition, if a single engine failure or other equivalent faults are added during takeoff, it is easy to cause human error. How to reduce the crew load through automation and put the crew in a monitoring role will help reduce the crew burden and reduce the risk of human error, thereby further reducing the safety risks of the aircraft.
[0027] However, modern aircraft provide takeoff pitch and thrust control by providing flight guidance and autothrottle, and provide speed targets through the flight control panel or flight management system, requiring the crew to switch modes and change speed targets according to information such as PFD prompts. During the ground phase, the crew activates the flight guidance mode and TOGA thrust mode, and after passing the thrust reduction altitude, changes the thrust mode to reduce thrust, and after reaching the acceleration altitude, switches the flight guidance pitch mode to accelerate until the takeoff process is completed.
[0028] For example, when a certain series of aircraft is not in flight guidance management mode, the crew needs to manually switch to climb mode; a certain series of aircraft has a passive throttle station, which requires the crew to control the throttle according to the prompt, and it is impossible to avoid the problem of early thrust retraction caused by the crew's premature exit from takeoff mode. The existence of these problems will also increase the crew's operating burden and cause certain safety hazards during the takeoff phase of the aircraft.
[0029] Based on the above problems, the embodiments of the present application provide a takeoff profile guidance method, system, electronic device and storage medium, which can automatically control the thrust of the aircraft in the takeoff profile, reduce the load of the crew during the takeoff phase, and thus reduce the probability of erroneous operation of the crew due to the busy takeoff phase, thereby reducing the safety risks of the aircraft.
[0030] Furthermore, the present application can also perform automatic guidance in the event of a single engine failure, thereby reducing the load on the unit.
[0031] Figure 1 The take-off profile guidance method provided by an embodiment of the present invention includes:
[0032] S101, obtaining the flight status of the aircraft to determine whether the aircraft is in the take-off phase;
[0033] S102, if the aircraft is in the take-off phase, activating the pitch guidance and maximum thrust mode of the aircraft;
[0034] S103, obtaining the engine status of the aircraft and the real-time altitude of the aircraft;
[0035] S104, if the engine status is dual engine, execute the first guidance;
[0036] S105, if the engine is single engine, execute the second guidance;
[0037] S106: After the real-time altitude of the aircraft is greater than or equal to 1500 feet and the speed reaches the preset final takeoff speed, the thrust of the aircraft engine is reduced to complete the takeoff.
[0038] In this embodiment, the pitch guidance and maximum thrust mode recorded in step S102 are both pre-set, and the pitch guidance is the guidance of the pitch angle of the aircraft at different stages, and the aircraft adjusts the pitch angle at takeoff according to the pitch guidance.
[0039] In step S103, the engine status of the aircraft is divided into dual-engine and single-engine failures. This embodiment can perform different guidance according to the different engine statuses, thereby reducing the operating load of the crew under different engine statuses.
[0040] See also Figure 2 In some embodiments, the execution steps of the first guidance in step S104 include:
[0041] S1041, determining whether the real-time altitude is greater than or equal to a preset twin-engine thrust reduction altitude;
[0042] S1042. If the real-time altitude is greater than or equal to the twin-engine thrust reduction altitude, convert the flight mode of the aircraft to the maximum climb force mode; otherwise, keep the aircraft in the maximum thrust mode until the real-time altitude is greater than or equal to the twin-engine thrust reduction altitude;
[0043] S1043, after the aircraft is in the maximum climb force mode, determining whether the real-time altitude is greater than or equal to a preset twin-engine acceleration altitude;
[0044] S1044: If yes, convert the pitch guidance to the aircraft's autopilot climb control mode to accelerate the aircraft.
[0045] In step S1042, if the real-time altitude of the aircraft is less than the twin-engine thrust reduction altitude, it means that the altitude of the aircraft has not yet reached the altitude for executing the next command, so it is necessary to continue to maintain the maximum thrust mode until the real-time altitude of the aircraft is greater than or equal to the twin-engine thrust reduction altitude.
[0046] In step S1043, if the real-time altitude of the aircraft is less than the twin-engine acceleration altitude, it means that the altitude of the aircraft cannot reach the altitude for executing the next command, so it is necessary to continue to maintain the pitch guidance and maximum climb thrust mode unchanged until the real-time altitude of the aircraft is greater than or equal to the twin-engine acceleration altitude.
[0047] See also Figure 3 In some embodiments, the execution steps of the second guidance in step S105 include:
[0048] S1051, determining whether the real-time altitude is greater than or equal to a preset single-engine thrust reduction altitude;
[0049] S1052: If the real-time altitude is greater than or equal to the single-engine thrust reduction altitude, determining whether the real-time altitude is less than a preset single-engine acceleration altitude;
[0050] S1053, if the real-time altitude is less than the preset single-engine acceleration altitude, converting the thrust of the aircraft to the maximum single-engine thrust;
[0051] S1054: If the real-time altitude is greater than or equal to the preset single-engine acceleration altitude, converting the pitch guidance to the aircraft's autopilot climb control mode, and converting the aircraft's thrust to the maximum single-engine thrust;
[0052] S1055: If the real-time altitude is less than the single-engine thrust reduction altitude, maintaining the maximum thrust mode, and determining whether the real-time altitude is greater than or equal to the single-engine acceleration altitude;
[0053] S1056. If the real-time altitude is greater than or equal to the single-engine acceleration altitude, convert the thrust of the aircraft to the maximum single-engine thrust; otherwise, maintain the maximum thrust mode until the real-time altitude is greater than or equal to the single-engine acceleration altitude, and convert the thrust of the aircraft to the maximum single-engine thrust.
[0054] In this embodiment, if the aircraft's engine status is single-engine during takeoff, it is determined that the aircraft has a single-engine failure. The aircraft can still perform the flight mission normally under a single-engine failure, but requires different guidance from a twin-engine. In step S1051, it is still necessary to determine whether the aircraft's real-time altitude is greater than or equal to the single-engine thrust reduction altitude.
[0055] If the real-time altitude of the aircraft is less than the single-engine thrust reduction altitude, it means that the real-time altitude of the aircraft is not enough, and the aircraft still needs to continue to maintain the maximum thrust mode until the real-time altitude of the aircraft is greater than or equal to the single-engine acceleration altitude. In this case, it is further determined that the real-time altitude of the aircraft is greater than or equal to the single-engine acceleration altitude, and the thrust mode is directly converted to the maximum single-engine thrust, and the autopilot climb control mode is activated until step S106 is reached; if the real-time altitude of the aircraft is greater than or equal to the thrust reduction altitude, it is still necessary to determine whether the real-time altitude is less than the single-engine acceleration altitude. If the real-time altitude of the aircraft is greater than or equal to the single-engine acceleration altitude, the thrust mode is directly converted to the maximum single-engine thrust, and the autopilot climb control mode is activated until step S106 is reached;
[0056] If the real-time altitude of the aircraft is greater than or equal to the single-engine reduced thrust altitude, it is necessary to determine whether the real-time altitude of the aircraft is less than the single-engine accelerated altitude. If so, the thrust mode is directly converted to the maximum single-engine thrust until step S106 is reached. Otherwise, the thrust mode is directly converted to the maximum single-engine thrust, and the autopilot climb control mode is activated until step S106 is reached.
[0057] Therefore, the takeoff profile guidance method provided in this embodiment can automatically control the thrust of the aircraft in the takeoff profile, reduce the load on the crew during the takeoff phase, and thus reduce the probability of erroneous operation due to the busy takeoff phase of the crew, thereby reducing the potential safety hazards of the aircraft. In addition, this embodiment can also perform automatic guidance in the event of a single engine failure, thereby reducing the load on the crew.
[0058] In some embodiments, the takeoff profile guidance method also includes: when the engine status is twin-engine or single-engine, when the pitch guidance is converted to the aircraft's autopilot climb control mode, the aircraft's flap handle status is also obtained, and the aircraft's speed target is automatically adjusted according to the flap handle status.
[0059] In this embodiment, the flap angle of the aircraft can be adjusted through the aircraft flap handle, so that the aircraft can take off in a more suitable posture.
[0060] In this embodiment, the twin-engine thrust of the aircraft is greater than the single-engine thrust. Therefore, when reaching the thrust reduction altitude during takeoff, the single-engine and twin-engine are distinguished, so that takeoff can be better performed according to the different states of the aircraft engines.
[0061] In some embodiments, if the aircraft has an automatic throttle system, then during the step of activating the pitch guidance and maximum thrust mode of the aircraft, the guidance method further includes: starting the automatic throttle system.
[0062] In this embodiment, some aircraft have an automatic throttle system, and the above-mentioned embodiments of the present application can be used to perform automatic throttle control in various stages of flight to further reduce the load on the crew.
[0063] In some embodiments, during the step of activating the pitch guidance and maximum thrust mode of the aircraft, the guidance method further comprises: locking the maximum thrust mode.
[0064] In this embodiment, the aircraft needs a maximum thrust mode in some stages of takeoff, such as the initial stage of takeoff, and this embodiment locks the maximum thrust mode to prevent the crew from making erroneous operations on the aircraft thrust, thereby reducing safety risks of the aircraft.
[0065] In step S101 of some embodiments, the step of obtaining the flight status of the aircraft to determine whether the aircraft is in the take-off phase includes:
[0066] The aircraft's air-ground status, push rod and thrust are checked to determine whether the aircraft's push rod is in the take-off position, whether the aircraft's thrust is the take-off thrust, and whether the aircraft's take-off / go-around button is activated. If the aircraft's push rod is in the take-off position, the aircraft's thrust is the take-off thrust, or the take-off / go-around button is activated, the aircraft is in the take-off stage.
[0067] In this embodiment, it is possible to determine whether the aircraft is in the take-off phase. Only when the aircraft is in the take-off phase can the take-off profile guidance be performed.
[0068] In some embodiments, the guidance method also includes: displaying real-time changes of the aircraft on a predetermined terminal, the real-time changes including the real-time altitude of the aircraft, engine status, engine thrust, the maximum climb force mode, the pitch guidance, the maximum thrust mode, and the autopilot climb control mode.
[0069] In this embodiment, by displaying the above information on the predetermined terminal, the crew can understand the status of the aircraft more clearly. In addition, since there are emergencies in the flight of the aircraft, there will naturally be some emergencies during the take-off phase. When the take-off profile guidance method recorded in the above embodiment of the present application is not sufficient to deal with these emergencies, the crew can judge the status of the aircraft based on the displayed information and perform manual intervention to further improve the safety of the flight mission.
[0070] Therefore, the takeoff profile guidance method provided in the embodiment of the present application can be based on the thrust reduction altitude, acceleration altitude and configuration information. In this embodiment, the configuration information is the flap information of the aircraft. The takeoff profile guidance method provided in the present application can greatly reduce the crew load during the takeoff phase by locking and releasing the thrust mode, automatically switching the pitch mode and the speed target, and coordinating the changes in information displayed on the predetermined terminal.

[0074] The real-time altitude acquisition module 3 is used to acquire the engine status of the aircraft and the real-time altitude of the aircraft;
[0075] The takeoff process guidance module 4 is used to determine whether the real-time altitude is greater than or equal to the preset dual-engine thrust reduction altitude if the engine status is dual-engine; if the real-time altitude is greater than or equal to the dual-engine thrust reduction altitude, the flight mode of the aircraft is converted to the maximum climb force mode, otherwise the aircraft is kept in the maximum thrust mode until the real-time altitude is greater than or equal to the dual-engine thrust reduction altitude; after the aircraft is in the maximum climb force mode, determine whether the real-time altitude is greater than or equal to the preset dual-engine acceleration altitude; if so, convert the pitch guidance to the aircraft's autopilot climb control mode to accelerate the aircraft; the takeoff process guidance module 4 is also used to determine whether the real-time altitude is greater than or equal to the preset single-engine thrust reduction altitude if the engine status is single-engine; if the real-time altitude is greater than or equal to the single-engine thrust reduction altitude If the real-time altitude reaches the single-engine thrust reduction altitude, it is determined whether the real-time altitude is less than the preset single-engine acceleration altitude; if the real-time altitude is less than the preset single-engine acceleration altitude, the thrust of the aircraft is converted to the maximum single-engine thrust; if the real-time altitude is greater than or equal to the preset single-engine acceleration altitude, the pitch guidance is converted to the aircraft's autopilot climb control mode, and the thrust of the aircraft is converted to the maximum single-engine thrust; if the real-time altitude is less than the single-engine thrust reduction altitude, the maximum thrust mode is maintained, and it is determined whether the real-time altitude is greater than or equal to the single-engine acceleration altitude; if the real-time altitude is greater than or equal to the single-engine acceleration altitude, the thrust of the aircraft is converted to the maximum single-engine thrust; otherwise, the maximum thrust mode is maintained until the real-time altitude is greater than or equal to the single-engine acceleration altitude, and the thrust of the aircraft is converted to the maximum single-engine thrust;
