[0020] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The main solution of this application embodiment is: inputting flight signals into a preset flight simulation model to obtain the theoretical flight maneuver corresponding to the simulator to be flown; determining the theoretical vector data at each simulation moment based on the theoretical flight maneuver, and adjusting the theoretical flight maneuver based on the theoretical vector data and the historical vector data at each historical moment to obtain the target flight maneuver; and performing flight simulation on the simulator to be flown based on the target flight maneuver.

[0023] A flight simulator is a simulation device that can reproduce an aircraft and its aerial environment and allow for operation. It typically consists of five main parts: a simulated cockpit, a motion system, a visual system, a computer system, and an instructor's control console. It is mainly used to meet the equipment development and training needs of pilots in aviation, aerospace, and air force academies. However, when pilots input complex flight commands, the flight simulator cannot accurately perform the corresponding flight actions.

[0024] This application obtains the theoretical flight maneuvers corresponding to the simulator under test by inputting flight signals into a preset flight simulation model. Then, based on the theoretical flight maneuvers, it determines the theoretical vector data at each simulation moment. Finally, it adjusts the theoretical flight maneuvers based on the theoretical vector data and historical vector data at each historical moment to obtain the target flight maneuver. Based on the target flight maneuver, it then performs accurate and effective flight simulation on the simulator under test. In essence, this application first obtains the theoretical flight maneuvers corresponding to the simulator under test through a preset flight simulation model, then adjusts the theoretical flight maneuvers based on both theoretical and historical vector data, and finally performs accurate and effective flight simulation on the simulator under test based on the adjusted target flight maneuver.

[0025] It should be noted that the executing entity of this application can be a computing service device with data processing, network communication and program execution functions, such as the computer system in a flight simulator.

[0026] Based on this, the embodiments of this application provide a flight simulation method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the flight simulation method of this application.

[0027] In this embodiment, the flight simulation method includes the following steps: Step S10: Input the flight signal into the preset flight simulation model to obtain the theoretical flight action corresponding to the simulator to be flown.

[0028] Understandably, a flight simulator refers to a device that needs to perform flight simulations. Flight signals can come from the pilot's control devices, external program commands, etc., such as the pilot's control of the side stick / yoke (pitch, roll), foot pedals (yaw), and throttle (thrust). External program commands include autopilot commands, external training scripts, etc. The hardware device is equipped with high-precision sensors, such as Hall effect sensors, potentiometers, force sensors, etc., which convert physical displacement or pressure into electrical signals, which can be used as flight signals. The preset flight simulation model can be a pre-set model capable of performing flight simulations, through which theoretical flight maneuvers corresponding to flight signals can be generated.

[0029] It should be understood that inputting flight signals into a preset flight simulation model can specifically involve sending the flight signals to the simulator's input / output interface computer. In this way, the preset flight simulation model can output theoretical flight maneuvers, allowing the flight simulator to create an immersive and realistic flight experience based on these theoretical flight maneuvers.

[0030] Step S20: Determine the theoretical vector data at each simulated moment based on the theoretical flight maneuver, and adjust the theoretical flight maneuver based on the theoretical vector data and the historical vector data at each historical moment to obtain the target flight maneuver.

[0031] Understandably, theoretical flight maneuvers can be flight maneuvers within a simulated time period. At each simulated moment within the simulated time period, the corresponding theoretical vector data can be determined, which may include angular velocity vector data, position vector data, etc.

[0032] It should be understood that this embodiment can also obtain the flight actions of the flight simulator within a historical time period. At each historical moment within the historical time period, the corresponding historical vector data can be determined, and the theoretical flight actions can be adjusted based on the theoretical vector data at each simulation moment and the historical vector data at each historical moment to obtain the target flight actions.

[0033] Step S30: Perform flight simulation on the simulator to be flown based on the target flight action.

[0034] In practice, flight simulation can be performed on the flight simulator based on the adjusted target flight action, which can accurately obtain the target flight action corresponding to the flight signal, thereby improving the accuracy of the flight simulator in the flight simulation process.

[0035] This embodiment obtains the theoretical flight maneuvers corresponding to the simulator under test by inputting flight signals into a preset flight simulation model. Then, based on the theoretical flight maneuvers, it determines the theoretical vector data at each simulation moment. Finally, it adjusts the theoretical flight maneuvers based on the theoretical vector data and historical vector data at each historical moment to obtain the target flight maneuver. Based on the target flight maneuver, it then performs an accurate and effective flight simulation on the simulator under test. In essence, this embodiment first obtains the theoretical flight maneuvers corresponding to the simulator under test through a preset flight simulation model, then adjusts the theoretical flight maneuvers based on both theoretical and historical vector data, and finally performs an accurate and effective flight simulation on the simulator under test based on the adjusted target flight maneuver.

[0036] refer to Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the flight simulation method of this application.

[0037] Based on the first embodiment described above, in this embodiment, step S20 includes: Step S201: Determine the theoretical vector data at each simulated moment based on the theoretical flight maneuver.

[0038] Understandably, at each simulation moment within the simulation period, the corresponding theoretical flight maneuvers can be determined, and the theoretical vector data at each simulation moment can be determined based on the theoretical flight maneuvers at each simulation moment.

[0039] Step S202: Obtain the historical flight actions of the simulator to be flown within a historical time period, and determine the historical vector data at each historical moment based on the historical flight actions.

[0040] It should be understood that the historical time period can be the time period during which the flight simulator was previously used for flight simulation, such as within one hour or two hours. The historical flight actions of the flight simulator within the historical time period can be obtained. At each historical moment within the historical time period, the corresponding historical flight actions can be determined, and the historical vector data at each historical moment can be determined based on the historical flight actions at each historical moment.

[0041] Step S203: Adjust the theoretical flight maneuver according to the historical vector data and the theoretical vector data to obtain the target flight maneuver.

[0042] Furthermore, in order to effectively adjust the theoretical flight maneuvers, in this embodiment, step S203 includes: determining the historical environment information of the simulator to be flown within the historical time period and the simulation environment information within the simulation time period; selecting a matching initial vector data set from the historical vector data and the theoretical vector data based on the historical environment information and the simulation environment information; and adjusting the theoretical flight maneuvers based on the initial vector data set to obtain the target flight maneuvers.

[0043] Understandably, historical environmental information can be the environmental information of the flight simulator during a historical period, including information such as weather, temperature, and humidity, and the simulation environmental information within the simulation period is determined.

[0044] It should be understood that an initial vector data set that has passed the matching test can be selected from historical vector data and theoretical vector data based on historical environmental information and simulated environmental information. The initial vector data set may include several corresponding vector data sets, that is, corresponding historical vector data and theoretical vector data. Then, the theoretical flight maneuvers are adjusted based on the initial vector data set to obtain the target flight maneuver.

[0045] Furthermore, in order to effectively select the initial vector data set, in this embodiment, the step of selecting the initial vector data set that has passed the matching test from the historical vector data and the theoretical vector data based on the historical environment information and the simulated environment information includes: segmenting the historical time period and the simulated time period respectively to obtain the segmented historical time period and the segmented simulated time period; matching the segmented historical time period and the segmented simulated time period based on the historical environment information and the simulated environment information to obtain the time period that has passed the matching test; and selecting the initial vector data set corresponding to the time period that has passed the matching test from the historical vector data and the theoretical vector data.

[0046] It is understood that, preferably, the historical time period and the simulated time period can be set to have the same duration and the same segment duration. In this embodiment, the historical time period and the simulated time period can be segmented according to the preset duration to obtain the segmented historical time period and the segmented simulated time period. The number of segments in these two segmented time periods is the same.

[0047] It should be understood that the segmented historical time periods and segmented simulated time periods can be matched based on historical environmental information and simulated environmental information to obtain the time periods that have passed the match. In one feasible embodiment, the historical environmental information of each historical time period and the simulated environmental information of each simulated time period can be determined. If the environmental information is similar, such as the same weather or a small temperature difference, then the corresponding historical time period and simulated time period are determined to have passed the match, and these two time periods are taken as the time periods that have passed the match.

[0048] In a specific implementation, initial vector data sets corresponding to the time periods that have been matched can be selected from historical vector data and theoretical vector data. Initial historical vector data corresponding to the time periods that have been matched can be selected from historical vector data, and initial theoretical vector data corresponding to the time periods that have been matched can be selected from theoretical vector data. By taking the above initial historical vector data and initial theoretical vector data as a set of initial vector data sets, several initial theoretical vector data sets corresponding to all the time periods that have been matched can be obtained.

[0049] Furthermore, in order to accurately adjust the theoretical flight maneuvers, in this embodiment, adjusting the theoretical flight maneuvers based on the initial vector data set to obtain the target flight maneuver includes: clustering the initial vector data set to obtain several clusters; determining the target vector data set in each cluster, and determining the success vector data error corresponding to each cluster based on the target vector data set; predicting the failure vector data error corresponding to the time period of matching failure based on the success vector data error; and adjusting the theoretical flight maneuver based on the failure vector data error to obtain the target flight maneuver.

[0050] Understandably, for several initial vector data sets, clustering can be performed to obtain several clusters. The initial vector data sets can be clustered using the K-Means clustering algorithm, and each cluster can include several target vector data sets.

[0051] It should be understood that, for each cluster containing target vector data sets, the success vector error corresponding to each cluster can be determined based on the target vector data sets. In one feasible embodiment, the target vector data sets can be classified first. For each type of target vector data set, the error between each group of target vector data sets can be calculated, and the average of all errors can be used as the vector error of that type. The average of all types of vector errors can be used as the success vector data error for that cluster.

[0052] In a specific implementation, for the time period of matching failure, the failure vector data error can be predicted based on the success vector data error. In one feasible embodiment, the failure vector data corresponding to the time period of matching failure can be selected from the historical vector data, that is, the vector data other than the initial historical vector data. Then, it is determined which cluster the failure vector data belongs to. Specifically, it can also be determined based on environmental information. The failure vector data error corresponding to the failure vector data can be the success vector data error of the cluster to which it belongs. Then, the theoretical flight maneuver is adjusted based on the failure vector data error to obtain the target flight maneuver. In one feasible embodiment, all success vector data errors and failure vector data errors can be obtained as the total vector data error. Then, the change of the total vector data error is determined, and a mapping relationship between the total vector data error and environmental information can be constructed. Then, based on this mapping relationship, the data error of the vector data corresponding to the theoretical flight maneuver is determined, and the vector data is adjusted based on the data error to obtain the adjusted target vector data. Finally, the target flight maneuver is determined based on the target vector data.

[0053] This embodiment determines the theoretical vector data for each simulation moment based on the theoretical flight maneuver, then acquires the historical flight maneuvers of the simulator within a historical time period, and determines the historical vector data for each historical moment based on the historical flight maneuvers. Finally, it adjusts the theoretical flight maneuvers based on the historical vector data and the theoretical vector data to obtain the target flight maneuver. This embodiment adjusts the theoretical flight maneuvers based on historical and theoretical vector data, which can accurately and effectively adjust the theoretical flight maneuvers output by the preset flight simulation model, improving the accuracy of flight simulation performed by the simulator.

[0054] refer to Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the flight simulation method of this application.

[0055] Based on the above embodiments, in this embodiment, before step S10, the method further includes: Step S01: Construct a preset flight simulation framework based on the basic framework information corresponding to the flight simulator to be flown.

[0056] Understandably, this embodiment can construct a preset flight simulation framework corresponding to the flight simulator to be flown. First, a coordinate system can be selected, such as a ground coordinate system, a body coordinate system, or an airflow coordinate system. Then, six-degree-of-freedom motion equations can be implemented, such as translational equations, rotational equations, attitude representation, and numerical integration. Next, a basic environmental model can be constructed, such as a standard atmospheric model, a gravity model, or a simple wind field, thereby establishing rigid body motion mechanics and the basic environment to obtain the preset flight simulation framework.

[0057] Step S02: Fill the preset flight simulation framework with data based on the basic aerodynamic data corresponding to the simulator to be flown, and obtain the initial flight simulation model.

[0058] It should be understood that the basic aerodynamic data corresponding to the flight simulator may include lift, drag, pitch moment, etc. In a feasible embodiment, data can be filled into a preset flight simulation framework to obtain an initial flight simulation model, which includes an aerodynamic model, a propulsion system model, a landing gear ground model, etc.

[0059] Step S03: Perform flight control on the initial flight simulation model to obtain a preset flight simulation model.

[0060] In practical implementation, flight control can be performed on the initial flight simulation model. The flight control system may include a mechanical control model, a fly-by-wire flight control model, and a transmission model. The avionics and instrumentation system includes an air data computer, an inertial navigation system, an autopilot, and a fault and disturbance model. This can activate the neural network, integrate the flight control and system models, and obtain the preset flight simulation model.

[0061] Furthermore, in order to effectively obtain the theoretical flight maneuvers corresponding to the simulator to be flown, in this embodiment, step S01 includes: acquiring flight signals through sensors on the simulator to be flown and converting the flight signals into initial flight commands; processing the flight commands with control laws to obtain target flight commands; inputting the target flight commands into the transmission model to obtain a flight state vector; and inputting the flight state vector into the aerodynamic model to obtain theoretical flight maneuvers.

[0062] Understandably, flight signals can be collected through sensors on the flight simulator, such as Hall effect sensors and force sensors, and then converted into initial flight commands. For example, the throttle position [0, 1023] can be converted into engine thrust commands [idle speed, maximum takeoff thrust]. The initial flight command is not directly given to the aerodynamic model. Based on the current aircraft state (airspeed, altitude, angle of attack, etc.) and the initial flight command, a safe and expected control surface deflection command, i.e., the target flight command, can be calculated. For example, if the pilot pulls the stick sharply, the initial flight command is "elevator deflect 25 degrees upward," but the control law will determine: Is the current speed too high? Will it cause overload? Ultimately, it may output a command that has been subject to rate and permission restrictions, such as "elevator deflects upward at a rate of 30 degrees per second, up to a maximum of 15 degrees," as the target flight command.

[0063] It should be understood that the target flight command, after being processed by the control law, is input into the transmission model, outputting a smooth-changing actual control surface deflection angle over time, i.e., the flight state vector. This flight state vector is then input into the aerodynamic model, where new aerodynamic force and moment coefficients are interpolated from a large aerodynamic data table. Based on these coefficients, the total force and total moment generated by aerodynamics are calculated. Finally, the aerodynamic force, engine thrust, gravity, etc., are vector-summed to obtain the resultant force acting on the aircraft's center of mass. All moments are summed to obtain the resultant moment. Substituting the resultant force and resultant moment into the six-degree-of-freedom equations of motion, and through numerical integration, the aircraft's new velocity, new angular velocity, new position, and new attitude in the next simulation frame are calculated, thus obtaining the theoretical flight maneuvers.

[0064] This embodiment constructs a preset flight simulation framework based on the basic framework information corresponding to the simulator to be flown. Then, it fills the preset flight simulation framework with data based on the basic aerodynamic data corresponding to the simulator to be flown, obtaining an initial flight simulation model. Finally, it performs flight control on the initial flight simulation model to obtain the preset flight simulation model. This embodiment fills the constructed preset flight simulation framework with data and then performs flight control on the obtained initial flight simulation model, thereby effectively obtaining the preset flight simulation model.

[0065] Reference Figure 4 , Figure 4 This is a structural block diagram of the first embodiment of the flight simulator of this application.

[0066] like Figure 4 As shown, the flight simulation device proposed in this application includes: The motion determination module 10 is used to input flight signals into a preset flight simulation model to obtain the theoretical flight motion corresponding to the simulator to be flown.

[0067] This embodiment obtains the theoretical flight maneuvers corresponding to the simulator under test by inputting flight signals into a preset flight simulation model. Then, based on the theoretical flight maneuvers, it determines the theoretical vector data at each simulation moment. Finally, it adjusts the theoretical flight maneuvers based on the theoretical vector data and historical vector data at each historical moment to obtain the target flight maneuver. Based on the target flight maneuver, it then performs an accurate and effective flight simulation on the simulator under test. In essence, this embodiment first obtains the theoretical flight maneuvers corresponding to the simulator under test through a preset flight simulation model, then adjusts the theoretical flight maneuvers based on both theoretical and historical vector data, and finally performs an accurate and effective flight simulation on the simulator under test based on the adjusted target flight maneuver.
