Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of high-load flight simulation, and in particular to a high-load flight simulation method and a high-load flight simulation system. Background Art
[0002] The outstanding acceleration motion produced by the aerial stunts and tactical flying maneuvers of high-performance stunt planes and fighter planes brings strong stimulation to the pilots, directly affecting their operating skills, physiological and psychological state, and having a significant impact on the combat performance and combat capability of the fighter planes. It poses a threat to flight safety and has attracted great attention from all countries.
[0003] Most tactical flight courses contain "high G-force and high load" actions. Simply using an aircraft for high load training will consume the precious life of the aircraft and may damage the aircraft or even cause a flight accident. High load flight training must be conducted frequently and repeatedly to bring the advanced performance of the aircraft into play. Therefore, there is an urgent need for training equipment with high load simulation function - "high load tactical flight simulator".
[0004] Conventional simulators currently used at home and abroad only have instantaneous loads. Since there is no continuous load, they can only meet basic flight training and cannot give pilots the real feeling of fighter jet combat flight. Therefore, advanced countries are competing to invest heavily in the development of flight simulators with continuous loads for flight training. In the simulated flight with continuous high loads, the flight acceleration vector field acts on the human body, so that the pilot's vision, hearing, proprioception, and abdominal sense are aware of the impact of the environment, and the pilot's physiology and psychology are changed due to the stimulation of this acceleration vector field. The prior art already has a technology for evaluating the fidelity of motion perception simulation of continuous load simulators, such as patent CN111785124, a method for evaluating the fidelity of motion perception simulation of continuous load simulators, but it only adds the consideration of the direction perception error factor caused by the direction. Although the evaluation of simulation fidelity does increase the consideration factors, as mentioned above, the stimulation of continuous high load on pilots will produce physiological and psychological changes. During the pilot's driving process, there is not only sensory perception of speed, direction, weightlessness and overweight, but also a strong psychological and physiological reaction. The psychological and physiological changes reflect the direct impact of continuous high load on the pilot's control skills and mental ability. During the actual flight, a skilled pilot will consciously control the psychological and physiological tolerance of the control action according to his own psychology and physiology. However, since the simulator uses a centrifuge combined with related mechanical parts to simulate the flight state formed by the control action, the same flight state that the pilot hopes to form by the same driving operation may have an unpredictable greater instantaneous force or torque than the real aircraft, and cannot match the simulated real flight state. It needs to be further adjusted through the feedback system in time. However, since these previous instantaneous forces and torques may have exceeded the physiological and psychological tolerance of the simulator pilot, the simulator pilot loses consciousness or suffers significant damage to the body's physiological functions and cannot complete further compensation adjustments. Therefore, this patent application does not take into account the pilot's comprehensive perception formed by the overall psychological and physiological factors that have a greater impact during the flight, and the benchmark for the comparison process is unclear. Not only can it not truly evaluate the fidelity of the simulated flight of the continuous load simulator, but it may also cause psychological and physiological damage to the simulator pilot. Obviously, the existing technology does not establish the realism of the simulated flight of the continuous load simulator and the actual flight from the perspective of overall psychological and physiological factors, that is, it does not use comprehensive perception to establish simulation training that meets the training requirements, so that the simulator can be corrected in time when the simulator pilot has psychological and physiological discomfort, to avoid the situation where the instantaneous force and torque are too large and exceed the pilot's physiological and psychological tolerance, and to ensure the physical and mental health of the simulator pilot. Summary of the invention
[0005] In order to solve the technical problem that the prior art has not been able to improve the realism of a continuous high-load simulated flight environment through comprehensive human perception to meet training requirements, the present invention proposes a high-load flight simulation method and a high-load flight simulation system, which can improve the realism of a continuous high-load simulated flight environment through comprehensive human perception to meet training requirements.

[0054] The existing technology has a large number of empirical aerodynamic parameters and a large number of flight mechanics data corresponding to different aircraft models. The ministerial standard QJ2015-90 has released 81 aerodynamic parameters. Aviation medicine and animal experiments have a history of more than 40 years in my country in the psychological and physiological research of humans and animals in various body shapes and overweight environments, and have accumulated a large amount of empirical data. Therefore, combining a large number of actual empirical aerodynamic parameters, actual flight psychological and physiological tests, and aviation medicine animal experiments and other existing comprehensive research results can obtain different comprehensive body perception data of pilots in different specific flight states (flight postures). For the first time, the present invention associates these parameters and data with the psychological and physiological feelings (comprehensive body perception and parameters and data describing these perceptions) of pilots in these body shapes and pressures according to the aerodynamic parameters involved in different actual flight states and the resulting pilot postures and pressures, and aviation medicine and other research, and establishes a corresponding relationship between the actual psychological and physiological parameter values and the actual flight state, so that high load can be collected through sensors. The simulated psychological and physiological parameter values of the pilot in the simulated flight state corresponding to the actual flight state on the flight simulator are adjusted according to the differences between the simulated psychological and physiological parameter values of the high-load flight simulator and the actual psychological and physiological parameter values, and then the control system of the high-load flight simulator (the high-load flight simulation module in the high-load flight simulation system) is adjusted, so that the simulated flight state of the simulator of the present invention can reach 80% to 85% of the actual flight state, and the corresponding pilot's real-time body perception (including psychological and physical comprehensive perception) and the comprehensive perception of flight in the actual flight state are also adapted by about 80% to 85%.
[0055] Specifically, the present invention provides a high-load flight simulation method and simulation system, which establishes a high-load simulation aerodynamic equation through a main control computer module, and generates control information for simulating continuous high-load flight in combination with a drag coefficient correction, a lift coefficient correction, and a pitch moment coefficient correction generated by a human body perception processing module, including simulated flight parameters, simulated scene parameters, simulated sound parameters, and other information, which are applied to the high-load flight simulation module to realize continuous load simulation flight; the human body perception processing module uses a portable wireless sensor to collect simulated psychological and physiological parameters of the pilot in continuous load flight, and processes the simulated psychological and physiological parameter values according to the correspondence between the actual psychological and physiological parameter values stored in the human body comprehensive perception model and the actual flight state, thereby adjusting the aerodynamic equation according to the difference between the aerodynamic parameter data of the simulated flight state of the high-load flight simulator and the aerodynamic parameter data of the actual flight state, including Equivalent predictive control correction, The correction amount of the human body comprehensive perception model is transmitted to the main control computer module, which forms new control information and applies it to the high-load flight simulation module to correct the control mechanism, visual unit and audio unit. When the simulator pilot subsequently manipulates the flight state, the simulated psychological and physiological perceptions produced by the simulator on the pilot, that is, the real-time comprehensive body perception, is adapted to the comprehensive flight perception of the pilot of the real aircraft in this flight state.
[0056] The high-load modeling of the present invention has both the characteristics of previous flight simulators and the embedding of a unique human comprehensive perception model, which is combined with the high-load flight simulation module to form control information, forming characteristics similar to motion platform control. These control information combined with comprehensive perception are information data that previous flight simulators have not accessed or collected, thereby improving the realism of flight training.

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0062] A high-load flight simulation method of this embodiment can obtain the corresponding relationship between the pilot's flight process corresponding to certain specific flight states, that is, the actual flight state and the actual psychological and physiological parameter values by associating existing psychological and physiological parameters and data such as psychological, muscle and nerve reactions under different gravity accelerations and different body postures in aviation medicine and animal experiments with actual empirical aerodynamic parameters, that is, flight control parameters, under more than 60 specific flight states. The simulators of the prior art use at most a dozen groups of aerodynamic parameters, which is far less than the number of the present invention. Aviation medicine is the study of people's adaptability to aircraft and the ability of aircraft to act on people, specifically the physiological reactions and psychological stimulation of pilots. The corresponding relationship can also be obtained directly by testing the corresponding relationship between the actual psychological and physiological parameter values and the actual flight state under different flight states when the pilot is performing a real flight. Therefore, the corresponding relationship between the above-mentioned actual psychological and physiological parameter values and the actual flight state can be obtained in a variety of ways. The actual flight state and the simulated flight state both include at least one of boundary flight, entering and recovering from a stall, and entering and recovering from a spin. The large number of subjects is more than 60 (basically covering all aviation combat training subjects, including special subjects such as "stall-spin"), preferably more than 80. The ministerial standard QJ2015-90 publishes more than 80 aerodynamic parameters, which can accurately describe various flight states.
[0063] The simulated psychological and physiological data of the pilot in the simulated flight state simulated for the actual flight state of an actual flight on the high-load flight simulator are collected by sensors to obtain simulated psychological and physiological parameter values, and the control of the high-load flight simulator control system is corrected according to the difference between the actual psychological and physiological parameter values and the simulated psychological and physiological parameter values, and the simulated flight state information of the high-load flight simulator is adjusted so that the further detected simulated psychological and physiological parameter values are adapted to the actual psychological and physiological parameter values, so that the corresponding relationship between the simulated psychological and physiological parameter values and the simulated flight state is adapted to the corresponding relationship between the actual psychological and physiological parameter values and the actual flight state, and the simulated flight state information includes displacement parameters and rod force parameters for driving the high-load flight simulator control mechanism.
[0064] The control of the control system is corrected, which means that the parameters of the high-load simulation aerodynamic equation of the high-load flight simulator are corrected according to the difference to obtain a correction amount, and new simulated flight state information is formed, and then the action of the high-load flight simulator control system is corrected, so that the simulator pilot's operation of the control mechanism enables the simulator pilot to obtain a comprehensive feeling that is adapted to the operation of the actual flight state; the parameters of the high-load simulation aerodynamic equation include longitudinal aerodynamic coefficients and lateral aerodynamic coefficients, and the longitudinal aerodynamic coefficients and lateral aerodynamic coefficients include correction amounts for the high-load simulation aerodynamic equations, and the psychological and physiological parameters include existing empirical parameters and data from aviation medicine and animal experiments.
[0065] The actual psychological and physiological parameter values and simulated psychological and physiological parameter values collected by the sensors include the psychological and physiological parameter values collected by the sensors attached to the pilot's head and face for approximately the same flight conditions (actual flight conditions and simulated flight conditions).
[0066] Under high-load flight, different flight states correspond to different aerodynamic equations and other different parameter values, and the pilots' perceptions of the flight process in different flight states also correspond to different specific psychological and physiological values. If there are differences between the parameter values of psychological and physiological perceptions, it means that there are differences in the parameter values of certain parameters of the aerodynamic equations. The corresponding parameters of the aerodynamic equations are adjusted to reduce the difference and applied to the high-load flight simulator in real time until the parameter values of the simulated comprehensive perception of the flight state are adapted to the parameter values of the actual comprehensive perception. This will enable the simulator to more realistically simulate real high-load flight.

The signal acquisition and communication system collects information (operation information) from the control mechanism, the visual unit and the audio unit and transmits it to the main control computer module, and receives control information from the main control computer module to control the device;
[0069] The human perception processing module includes a flexible wearable wireless sensor for detecting the pilot's psychology and physiology, a signal receiving module and a processing module. The signal receiving module receives the simulated psychological and physiological parameter values collected by the flexible wearable wireless sensor and inputs them into the processing module. The processing module stores a human comprehensive perception model. The human comprehensive perception model stores the correspondence between the actual psychological and physiological parameter values and the actual flight state established by associating a large number of existing empirical aerodynamic parameters with the actual psychological and physiological parameters of the pilot during flight, and the high-load simulation aerodynamic equation from the main control computer module. The processing module compares the simulated psychological and physiological parameter values with the actual psychological and physiological parameter values, and corrects the parameters of the high-load simulation aerodynamic equation according to the simulated correction amount formed by the difference between the two, so as to obtain the correction amount of the human comprehensive perception model to the high-load simulation aerodynamic equation, and transmit the correction amount to the main control computer module;

[0085] In the correction equations of the above parameters, except for the correction of each parameter by predictive control and the correction amounts in the human body comprehensive perception model based on the differences between the actual psychological and physiological parameter values and the simulated psychological and physiological parameter values, the other items are conventional calculation items of the existing high-load simulator.
[0086] The correction quantities of predictive control are the correction quantities caused by the difference between the control of the simulator and the control of the actual flight, because the control of the simulator is not a pulse quantity but a smooth quantity.
[0087] For example, this embodiment is to change the F of a certain force F n-1 , F n-2 ……F n-5 Items are compared to determine their trend, whether it is rising, falling, or a turning point. Then, according to the trend, F n+1 , F n+2 ……F n+5 For example, if the trend is rising, the current and voltage of F are increased or doubled, and vice versa if it is falling. The correction amount of predictive control is different for different aircraft models and different flight states.
[0088] In this embodiment, the correction amount in the human body comprehensive perception model according to the difference between the actual psychological and physiological parameter values and the simulated psychological and physiological parameter values is calculated by the mental ability parameter P q For example, when a pilot at sea actually flies a certain type of aircraft, although low-altitude flying is beneficial for avoiding radar, it is very difficult to control. Therefore, it is necessary to simulate the state of low-altitude flying over the sea. In the low-altitude flying state, the closer to the low altitude, the more tense the mind and muscles are. q Therefore, for the safety of flight, the mental ability P q Need to meet the requirements of the job. Figure 3The curves of the mental ability of sea flight and simulated flight change with the altitude (simulated altitude) S. The mental ability P has been obtained based on the empirical aerodynamic parameters of low-altitude flight and medical and animal experimental data. q The curve of the change with height, that is, the actual psychological and physiological parameter value curve, is the upper curve in the figure - the actual P q The corresponding relationship between the altitude parameter S and the low-altitude flight state, and S can correspond to the flight control parameter, that is, the other aerodynamic parameters can be related to the mental ability parameter P by the same logic. q The relationship between the actual flight state and the actual psychological and physiological parameters is established for a large number of aerodynamic parameters; the simulated psychological and physiological parameter values of the pilot under the corresponding flight state simulated on the high-load flight simulator are collected by sensors, and the lower curve - simulated P q The corresponding relationship with the actual low-altitude flight state S, that is, the simulated P q The corresponding relationship with the simulated flight state is obtained according to the two curves. The control of the high load simulator control system can be corrected to adjust the simulated flight state so that the simulated P q Achieved and actual P q Adaptation; further, the association of other aerodynamic parameters with psychological and physiological parameters can have more corrections, conduct comprehensive evaluation, and obtain more accurate corrections: , , , , , thereby achieving a high degree of simulation of the low-altitude flight state.
