[0017] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0018] Hereinafter, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0019] In addition, the use of "based on" or "according to" means openness and inclusiveness, because the process, step, calculation or other action "based on" or "according to" one or more conditions or values can be based on additional conditions or values in practice.

[0020] The flight training simulator, as an important aviation simulation device, has controllability, non-destructiveness, economy, reliability and other characteristics compared with real flight test, and plays a very important role and positive significance in solving the problem. Therefore, at present, various flight training simulator technologies are being actively developed, and the main development trend of future flight training simulators is being researched.

[0021] At present, the flight training simulator has become an important equipment indispensable for pilot training. Using the flight training simulator for training has become an important direction of the development of flight training, and the reason is that: During the flight training process, higher costs are required, and the actual training not only needs complicated support technical personnel and support equipment, but also causes wear and tear to the actual equipment during the training process. Therefore, the flight training simulator can greatly reduce the training cost and improve the economic benefit.

[0022] The flight training simulator can break through the limitations of climate conditions, regions and environmental conditions, and can randomly select a training location according to a specific flight training task, and the training effectiveness is high.

[0023] When the pilot uses the flight training simulator to perform flight training, the pilot can repeatedly practice difficult projects according to his own conditions, greatly improving the training effect; the flight training simulator can avoid unsafe hidden dangers caused by the pilot's operation errors, greatly improving the safety.

[0024] The flight simulator can simulate flight on the ground, and is a test and training device that simulates the flight state, flight environment and flight conditions of an aircraft performing a flight task, and provides similar control load, vision, hearing and motion feeling to the pilot (flight crew). It is a simulation device that simulates the flight of an aircraft and has a relatively complex structure and complete functions, can reproduce the aircraft and the air environment, and can be operated, including various internal and external environmental conditions, which can reduce the cost and risk of pilot training.

[0025] Based on the above problems, an embodiment of the present application provides a simulation system of a flight simulator, as shown in Figure 1 The system includes a simulation cockpit, an operation loading module and a simulation calculation module. The simulation cockpit includes a simulation control instrument, and the simulation control instrument includes a joystick, a footrest and a control instrument. The simulation calculation module includes a target physical calculation engine, and the target physical calculation engine is deployed with a flight calculation model. The operation loading module is configured to acquire a control instruction based on the simulation control instrument in real time, and transmit the control instruction to the simulation calculation module. The simulation calculation module is configured to input the control instruction to the physical calculation engine, calculate the flight simulation result of the aircraft during the ski jump deck take-off by using the physical calculation engine, and determine the ski jump take-off effect of the flight simulator according to the flight simulation result in real time. The flight simulation result includes flight attitude information, flight motion information and collision information, and the collision information is used to indicate the collision information between the aircraft and the ski jump deck.

[0026] Specifically, the collision information includes: the landing point: the exact position where the aircraft first touches the deck. Usually referenced to the arresting wires on the deck (e.g., "hit the 3rd arresting wire"). The ideal landing point is between the 2nd and 3rd arresting wires. Sink rate: the vertical descent speed of the aircraft at the moment of contact with the deck (unit: feet per minute, ft / min). This is a key indicator of the strength of the landing impact, directly related to the stress on the aircraft structure and landing gear. Excessive sink rate is a sign of "heavy landing" and can cause damage. Horizontal speed / airspeed: the forward speed of the aircraft at the moment of contact with the deck (unit: knots). Too fast or too slow speed will affect the efficiency and safety of the arresting system. Angle of attack: the angle between the aircraft wing and the incoming airflow. For carrier-based aircraft (such as the F / A-18), maintaining the correct angle of attack (usually between 8-12 degrees) is crucial, as it ensures the controllability of the aircraft at low speed and the ideal landing attitude. Attitude angle: pitch angle: the angle of the aircraft nose up or down. The correct attitude is that the nose is slightly raised. Yaw angle: the angle between the aircraft longitudinal axis and the centerline of the deck. The ideal situation should be zero, i.e. the aircraft is completely aligned with the centerline of the deck. Any yaw can cause lateral impact and danger. Roll angle: whether the wings are level. At the moment of landing, the double wings must be kept level.

[0027] The application can comprehensively judge the ski-jump take-off effect of the aircraft according to the above collision information.

[0028] Optionally, the simulation calculation module is further used for: obtaining a first three-dimensional model of the flight simulator and a second three-dimensional model of the ski-jump deck, the first three-dimensional model including a three-dimensional model of the landing gear; obtaining an aircraft center of gravity calculation model, an aircraft motion calculation model, and a collision calculation model; deploying the first three-dimensional model, the second three-dimensional model, the aircraft center of gravity calculation model, the aircraft motion calculation model, and the collision calculation model in an initial physical calculation engine; after inputting the configuration parameters of the obtained first three-dimensional model and the configuration parameters of the second three-dimensional model into the initial physical calculation engine, generating the target physical calculation engine.

[0029] The initial physical calculation engine can use the PhysX engine, which is a physical simulation foundation and can simulate physical effects such as take-off, aircraft stress, wheel block collision, etc. The influence of wind and turbulence is calculated using a standard mathematical model.

[0030] It can be understood that the simulation calculation of flight needs to consider the influence of crosswind and turbulence during flight. The basic dynamic characteristics and collision constraint relationship are used in the modeling of landing gear, three-point independent modeling is adopted, and the changes in the motion state of the aircraft caused by the interaction between the landing gear and the ground during the taxiing take-off process are introduced; the Nvidia PhysX engine is used as the basis for physical simulation to simulate the physical effects such as take-off, aircraft stress, wheel block collision, etc.; the influence of wind and turbulence is calculated using a standard mathematical model.

[0034] According to the typical loading state of the aircraft in the task use mode, the weight of the aircraft is composed of the following items: Total aircraft weight = basic empty weight + use item + total fuel weight of each tank.

[0035] Set the corresponding identifier for each component of the aircraft weight, and set the composition item of the total aircraft weight through the loading mode and the landing gear flag.

[0036] Motion equation sub-module: according to the mass characteristic parameters of the aircraft and the aerodynamic force, ground force and engine thrust acting on the aircraft, calculate the linear (angular) acceleration, linear (angular) velocity, position and attitude of the aircraft. Motion data.

[0037] The solution of the motion equation is to calculate the flight parameters such as overload, speed, attitude and position of the aircraft according to the aerodynamic force, landing gear force and engine thrust. This module mainly completes: a) Solving the six-degree-of-freedom nonlinear rigid body motion equation of the aircraft; b) Calculate the resultant force, action point and moment generated by the external force acting on the aircraft; c) Calculate the position, attitude and other motion parameters of the aircraft.

[0038] According to the aerodynamic force and engine thrust and the aircraft weight and inertia moment, a rigid body space six-degree-of-freedom motion model of the aircraft can be established, that is, three plane motion models and three rotation motion models, outputting the X, Y and Z coordinates, velocity, acceleration of the aircraft, and the pitch angle, roll angle and true heading of the aircraft, and corresponding aircraft attitude angular velocity, attack angle, sideslip angle and other motion parameters.

[0040] Optionally, the system further comprises a visual simulation module. The simulation calculation module is further configured to transmit the flight simulation result to the visual simulation module, so as to display the flight simulation result by using the visual simulation module.

[0041] Optionally, the visual simulation module comprises a preset landscape model and a target entity model. The visual simulation module is further configured to pre-call the landscape model and the target entity model to generate a flight simulation scene.

[0042] Optionally, the visual simulation module is further configured to simulate a light effect by using a particle system, and guide the flight simulator to simulate the landing of the aircraft according to the simulated light effect and a positional relationship between the aircraft and the simulated light when the aircraft lands.

[0043] The application adds the distribution and motion of various personnel in the visual scene, establishes the action instruction model of various commanders, realizes the control of the aircraft operation program associated with the aircraft operation, completes the interactive simulation between the pilot operation and the flight command in the process from the engine starting to the release of the aircraft, and then to the landing of the aircraft, and achieves the purpose of operation program training.

[0044] In addition, the application calculates the positional relationship between the eye point of the aircraft and the landing guide light of the aircraft in real time, and completes the simulation of the glide state of the aircraft.

[0045] Optionally, the system further comprises an audio module; and the audio module is configured to call a preset audio material, synthesize an audio signal and output the audio signal to an audio device, so as to simulate the sound information in the flight process of the aircraft.

[0047] In addition, the manipulation program of some aircraft is largely subject to the instructions of ground personnel, especially the take-off command assistant, and the instructions of these personnel are issued through gestures and body language, so it is necessary to establish a human motion model for instruction issuance and a personnel distribution state model, which is combined with the aircraft state and the pilot manipulation to achieve the purpose of familiarization and training of the operation process in the process of starting the car to take-off and landing recovery. The bone animation technology is used here to realize the running, squatting, standing and various command actions of virtual personnel, smooth transition processing, and the behavior of personnel is driven by artificial intelligence technology.

[0049] As shown in Figure 2 , the working principle diagram of the simulation system of the flight simulator, when the system works, the task console subsystem sends control instructions to other subsystems to control the running state of the whole system.

[0050] The whole system collects the control signals of the pilot in real time through input devices (including the driving rod, the throttle lever, the foot pedal, etc.), solves the mathematical models and logic models of flight simulation and avionics simulation in real time, and transmits the solved flight state parameters to the visual simulation, sound simulation, cockpit simulation, and task console subsystems, which are respectively used to drive the visual display, sound effect, and cockpit instrument display, and record and process all information and flight data of a flight training through the task console subsystem.

The operator feeds back the information seen and heard, and makes correct control, thereby constituting the simulation in the human-in-the-loop.

[0052] To realize the above functions, the development of the project has experienced several stages such as scheme demonstration, detailed design, hardware processing, software development, integration debugging, and trial operation.

The design also fully considers various possible situations during system operation, follows the popular open standards in network communication and data interconnection, and meets the needs of expansion and upgrading.

[0056] The physical simulation module adopts the PhysX engine.
