Description

Technical Field

[0001] This invention relates to the field of flight simulation technology, and more specifically to a method for simulating the illusion of tilted flight. Background Technology

[0002] Flight illusion, also known as spatial disorientation disorder, is a pilot's erroneous perception of the aircraft's or their own position, attitude, direction, and motion during flight. Flight illusion is one of the most significant factors in serious human-related flight accidents, prevalent among flight personnel, affecting pilot performance, and jeopardizing flight safety. Normally, the human body relies primarily on its vision, vestibular sense, and proprioception for spatial orientation and to determine its own state and position. When pilots are in flight, the physiological functions of the human sensory organs and the motor perception patterns of the central nervous system have certain limitations under the complex six-degree-of-freedom motion and restricted visual conditions of the air, leading to flight illusions. Complex weather conditions such as clouds, fog, rain, and snow encountered during flight, linear acceleration and angular velocity stimuli during flight, as well as nighttime and sea-based flights, are all important factors inducing flight illusions.

[0003] The tilt illusion is a pilot's misperception of the aircraft's bank angle. It is one of the most common and frequent flight illusions. The tilt illusion manifests primarily as the pilot feeling the aircraft is banked when it is actually level or making a horizontal turn; conversely, when the aircraft is actually banked, the pilot feels level, or overestimates or underestimates the bank angle. The tilt illusion can be induced by vestibular and proprioceptive information. In related technologies, overcoming the tilt illusion generally involves flying according to visual instruments, which is an effective and conventional method for spatial orientation and overcoming flight illusions. Although various flight illusions can occur in daily flight due to certain external factors and the pilot's own internal factors, relying on reliable and accurate directional information sources, such as flying according to instruments, can effectively overcome flight illusions and prevent flight accidents.

[0004] Instrument visual spatial orientation (AVSO) is the most reliable source of orientation information in flight. However, compared to visual orientation information such as horizon lines and landmarks, AVSO suffers from indirectness and instability. If pilots are not proficient in instrument flight techniques and cannot recognize and identify flight illusions, AVSO will be ineffective, leading to flight accidents. Therefore, conducting tilt flight illusion experience training on flight illusion simulators to help pilots recognize, identify, and correctly handle flight illusions is an effective way to reduce the rate of flight accidents caused by illusions.

[0005] In conventional tilt flight illusion simulation methods based on flight illusion simulators, trainees can detect and correct abnormal aircraft bank angles early by observing flight instruments in a timely manner, resulting in a low success rate for tilt flight illusion simulation. To address this, an improved tilt flight illusion simulation method involves shutting down or freezing the aircraft's horizon indicator and head-up display before the illusion occurs, reducing or stopping the provision of instrument orientation information to trainees. This forces trainees to rely primarily on their vestibular and proprioceptive systems for spatial orientation, thereby improving the success rate of tilt flight illusion simulation. However, this improved method suffers from inconsistencies with actual flight instrument displays, affecting the immersion in the simulated flight mission and resulting in lower realism and intensity of the tilt illusion experienced by trainees. Summary of the Invention

[0006] This invention provides a method for simulating tilted flight illusion, which improves the simulation effect of tilted flight illusion, helps pilots better identify and correctly handle flight illusion, and effectively reduces the flight accident rate caused by illusion.

[0007] Therefore, the present invention provides the following technical solution:

[0012] A third flight instruction message is issued to the trainee to quickly change from banked flight to level flight, so that during the cockpit roll, the trainee's vestibular sensory organs are subjected to Coriolis acceleration, producing the illusion of tilted flight;

[0013] A fourth flight instruction message is issued to the trainee to gradually eliminate the illusion of tilted flight.

[0014] Optionally, the target flight mission is a complex weather flight under preset daytime meteorological parameters.

[0030] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0033] To address the problems of existing tilt flight illusion simulation methods, such as inconsistencies with actual flight instrument displays, which affect the immersion of simulated flight missions and result in lower realism and intensity of tilt illusions experienced by trainees, this invention proposes a tilt flight illusion simulation method. Utilizing a flight illusion simulator, this method generates Coriolis acceleration to stimulate the pilot's vestibular sensory organs by setting flight courses and complex weather conditions. This allows pilots to experience and correctly identify tilt flight illusions during simulated flight missions. Compared to general tilt flight illusion simulation methods, this method is less affected by instrument orientation information in the trainee's spatial orientation, has a higher success rate in inducing tilt flight illusions, and achieves higher realism and intensity.

[0034] The following is a brief description of the flight illusion simulator used in the tilted flight illusion simulation method of the present invention.

[0035] like Figure 1 The diagram shown is a structural schematic of a flight illusion simulator used in the tilted flight illusion simulation method of the present invention.

[0036] The flight illusion simulator 100 includes: a simulated cockpit 101, a six-degree-of-freedom motion platform 102, a 360-degree continuous rotation platform 103, a simulation system 104, and a management and control system 105. Among them:

[0037] The simulated cockpit 101 is used to carry trainees and move under the influence of the six-degree-of-freedom motion platform 102 and the 360-degree continuous rotation platform 103. The simulated cockpit 101 includes a control system 111, a visual display system 112, and an instrument display system 113. The control system 111 includes a control stick, rudder pedals, and throttle. The instrument display system 113 includes a head-up display and a horizon indicator. The visual display system 112 includes an external visual display.

[0038] The aforementioned 360-degree continuous rotating platform 103 can be fixedly installed on the upper part or the lower part of the six-degree-of-freedom motion platform 102. It drives the simulation cockpit 101 fixed thereon, or drives the six-degree-of-freedom motion platform 102 and the simulation cockpit 101 fixed thereon, to rotate continuously around the vertical axis by ±360 degrees.

[0039] The aforementioned simulated cockpit 101 is fixedly mounted on the 360-degree continuous rotating platform 103 or the six-degree-of-freedom motion platform 102. The simulated cockpit 101 is equipped with a visual display system 112, an instrument display system 113, and a control system 111. The visual display system 112 provides a simulated flight scene, the instrument display system 113 includes a horizon indicator, a head-up display, and a liquid crystal instrument panel for displaying flight instruments, and the control system 111 receives flight control commands from the trainee.

[0040] The simulation system 104 is used to collect the trainee's control command signals. Based on the collected trainee's control command signals, the status and environmental information of the flight illusion simulator 100, and the preset flight model, the system calculates the flight parameters of the simulator 100 in real time and sends the flight parameters to the six-degree-of-freedom motion platform 102, the visual display system 112, and the instrument display system 113 in real time to provide real-time feedback to the trainee on the flight status under the current operation command.

[0041] The aforementioned management and control system 105 includes an interaction module, a control module, and a monitoring and storage module. The interaction module receives selections of flight modes and parameters from trainees; the control module executes the steps of the Coriolis flight illusion simulation method provided by this invention; and the monitoring and storage module collects, monitors, and stores the operating parameters and status of various systems, including the motion platform and flight simulation, as well as the physiological and behavioral status of trainees.

[0042] In one non-limiting embodiment, the six-degree-of-freedom motion platform 102 may include a spatial parallel motion mechanism, which includes a lower fixed platform, an upper motion platform, six servo actuators, a universal joint connector, and a travel limit mechanism.

[0043] For example, by controlling the servo motor to change the length of the actuator, the attitude changes of the simulated cockpit on the upper part of the six-degree-of-freedom motion platform can be driven, realizing pitch, roll, and yaw motions around three spatial coordinate axes and linear motions along three axes, including rise, fall, lateral, and longitudinal movements. After receiving the aircraft motion parameters such as real-time speed and acceleration from the simulation system 104, the control module of the six-degree-of-freedom motion system converts them into motion parameters for the platform, controlling the six-degree-of-freedom motion platform 102 to provide the trainees in the simulated cockpit 101 with overload sensations and dynamic information on attitude angle changes within a certain range, so that the pilots experience a motion sensation consistent with the actual flight environment and mission conditions.

[0044] The six-degree-of-freedom motion platform 102 has a motion washout function. The motion washout function represents the process by which the six-degree-of-freedom motion platform 102 can return to the neutral position with a smooth motion below the human vestibular sensory threshold after completing a sudden motion, so that the six-degree-of-freedom motion platform 102 can execute the next sudden motion command within the preset displacement stroke range.

[0045] For example, the visual display system 112 may include a display subsystem, a visual generation subsystem, and a scene database, providing pilots with realistic, stable, and real-time simulated images of the aircraft cockpit exterior to determine the aircraft's attitude, position, weather conditions, and ground and air targets. The display subsystem may employ projection display or liquid crystal display technology; the visual generation subsystem may generate images of complex weather conditions such as terrain, clouds, rain, and fog, as well as three-dimensional objects, in real time based on a high-performance graphics workstation and visual simulation software, thus completing scene management; the scene database provides geographical databases such as plains, forests, and oceans, as well as three-dimensional object databases of aircraft, airports, and buildings.

[0046] The control system 111 may include: a control stick, rudder pedals, and throttle. The main function of the control system 111 is to respond to the pilot's control commands and provide control command input for flight simulation.

[0047] The instrument display system 113 simulates various flight instruments and head-up displays (HUDs) within an aircraft cockpit. Flight instruments are displayed on the central instrument cluster's LCD panel, while the HUD image is displayed within the central field of view of the visual display subsystem. The appearance of the instruments and their performance characteristics within the simulation range are consistent with the simulated aircraft model. The flight instruments on the central instrument cluster mainly include an altitude indicator, airspeed indicator, altimeter, and compass; the HUD can indicate flight heading, rate of climb, airspeed, altitude, pitch angle, and roll angle.

[0048] In this flight illusion simulator 100, the simulation system 104 collects pilot control command signals, aircraft status, and environmental information in real time. Based on the aircraft aerodynamic model, mass characteristic model, and engine model, it calculates flight parameters such as aircraft speed, acceleration, and Euler angles. The simulation system 104 sends the flight parameters in real time to the six-degree-of-freedom motion platform 102, the visual display system 112, and the instrument display system 113, providing real-time feedback on the flight status to the pilot.

[0049] In the flight illusion simulator 100, the management and control system 105 is the main interface of the flight illusion simulator 100. It can provide training personnel with function options and parameter settings, control the implementation of flight illusion simulation methods, and realize the collection, monitoring and storage of the operating parameter status of each system and the physiological behavior status information of the trainees.

[0050] This invention provides a method for simulating tilted flight illusions in the aforementioned flight illusion simulator. By setting flight courses and complex weather conditions, it generates Coriolis acceleration to stimulate the pilot's vestibular sensory organs, enabling the pilot to experience and correctly identify tilted flight illusions during simulated flight missions.

[0051] like Figure 2 The diagram shown is a flowchart of a Coriolis flight illusion simulation method provided by the present invention, which includes the following steps:

[0052] Step 201: Receive the flight parameter settings from the trainer and generate the target flight mission.

[0053] The target flight mission may include, but is not limited to, daytime complex weather flight missions. The preset complex weather conditions may include, but are not limited to, any of the following: flight in clouds, flight above clouds with cloud cover >40%, flight below clouds with visibility <5km, etc.

[0054] Simultaneously refer to Figure 1 For example, trainers can input flight parameters through the interactive module in the management system 105 of the flight illusion simulator 100. The flight illusion simulator 100 generates a target flight mission based on the received flight parameter settings. The preset meteorological parameters for the target flight mission in the flight illusion simulator 100 are set as follows: visibility 3km, cloud cover 60%, cloud base height 2000m, and cloud thickness 2000-3000m. The target flight mission can be selected as a complex weather flight mission, and the time can be selected as daytime. The aircraft type, airport location, etc., can be selected according to the relevant configuration options of the flight illusion simulator 100; this embodiment does not limit this selection.

[0055] Setting target flight missions in the above manner makes it impossible for pilots to see landmarks during flight. The horizon line, which is the reference point for visual spatial orientation, "disappears." The view outside the window cannot provide motion cues, which will cause pilots to have difficulty with spatial orientation. As a result, they rely more on the vestibular sensory system for orientation, which can easily lead to vestibular flight illusions.

[0056] Step 202: Issue a first flight instruction message to the trainee so that the trainee can complete the takeoff operation according to the information displayed by the instrument display system under the instruction of the first flight instruction message and maintain level flight after reaching the preset altitude.

[0057] The preset altitude is greater than the cloud height; for example, the preset altitude is preferably greater than 3000 meters.

[0058] Step 203: Issue a second flight instruction message to the trainee so that the trainee, under the instruction of the second flight instruction message, enters a continuous horizontal turn during the level flight phase according to the information displayed by the instrument display system.

[0059] Specifically, when trainees enter a continuous horizontal turn during level flight, they can rapidly roll to the right or left with an angular acceleration exceeding the human sensory threshold to a maximum bank angle of 30° and maintain that altitude.

[0060] Specifically, refer to Figure 1 The simulation cockpit 101 can be rolled and tilted to the right or left by a set angle by controlling the six-degree-of-freedom motion platform 102. At the same time, the 360-degree continuous rotation platform 103 can be controlled to drive the simulation cockpit 101 to slowly accelerate to the right or left to a set angular velocity with an angular acceleration below the human sensory threshold, and then continue to rotate at a constant speed.

[0061] For example, after the aircraft completes the takeoff phase and enters level flight at a predetermined altitude, the trainee rapidly rolls to the right (or left) with an angular acceleration greater than the human sensory threshold (e.g., the threshold is 0.5° / s²) to the maximum bank angle of 30° and maintains the altitude.

[0062] During this process, the six-degree-of-freedom motion platform 102 is controlled to slowly tilt upwards to a set angle with an angular acceleration lower than the human sensory threshold. At the same time, the 360-degree continuous rotation platform 103 is controlled to slowly accelerate to the right or left with an angular acceleration lower than the human sensory threshold until it reaches a set angular velocity and then continues to rotate at a constant speed.

[0063] For example, the six-degree-of-freedom motion platform 102 is controlled to rotate the simulated cockpit 101 15° to the right (or left-right) with an angular acceleration higher than the human perception threshold. Then, the six-degree-of-freedom motion platform 102 is controlled to slowly pitch up 15° with an angular acceleration lower than the human perception threshold, while simultaneously, the 360-degree continuous rotation platform 103 is controlled to slowly accelerate to the right (or left) to 20° / s with an angular acceleration lower than the human perception threshold. During this process, the trainee in the cockpit does not feel the pitch up around the horizontal axis or the continuous rotation to the right (or left) around the vertical axis, consistent with the actual flight experience.

[0064] Step 204: Issue a third flight instruction to the trainee to quickly change from banked flight to level flight, so that during the cockpit roll, the trainee's vestibular sensory organs are subjected to Coriolis acceleration, creating the illusion of tilted flight.

[0065] For example, after the aircraft enters a sustained 45° right (or left) bank turn for 60 seconds, the trainee, based on information from the horizon indicator or head-up display, maneuvers the aircraft to quickly roll 45° to the left (or right) to restore a level flight attitude. During this process, the six-degree-of-freedom motion platform is controlled to move the simulated cockpit from an upward position to a downward angle around the pitch axis within a set time, restoring the simulated cockpit to a neutral position. For instance, the six-degree-of-freedom motion platform 102 is controlled to move the simulated cockpit 101 from an upward position to a downward angle around the pitch axis within 2 seconds, restoring the simulated cockpit 101 to a neutral position. At this time, while the pilot is rotating to the right (or left) at 20° / s around the vertical axis, they are also rotating around the second axis, the pitch axis. The pilot's vestibular system is subjected to Coriolis acceleration, producing a strong feeling of rolling to the left (right) and tilting around the third axis, the roll axis, consistent with the feeling of tilting illusion during actual flight.

[0066] Step 205: Issue a fourth flight instruction message to the trainee to gradually eliminate the illusion of tilted flight.

[0067] The fourth instruction is used to instruct the trainee to firmly believe in the instrument parameters and maintain level flight.

[0068] For example, the trainee is instructed to trust the instrument parameters and maintain level flight for 60 seconds. During this process, the 360-degree continuously rotating platform 103 drives the simulated cockpit 101 to slowly decelerate to a stop at an angular acceleration below the human sensory threshold. Once the simulated cockpit 101 stops rotating about the pitch axis, the Coriolis acceleration experienced by the trainee disappears, and the flight illusion of tilting to the left (or right) gradually weakens and disappears.

[0069] The tilting flight illusion simulation method provided by this invention utilizes a flight illusion simulator to generate Coriolis acceleration to stimulate the pilot's vestibular sensory organs by setting flight subjects and complex weather conditions, enabling the pilot to experience and correctly identify tilting flight illusions during simulated flight missions.

[0070] Compared to conventional methods for simulating tilted flight illusions, the present invention reduces the influence of instrument orientation information on the trainee's spatial orientation, increases the success rate of induction, and enhances the realism and intensity of the tilted flight illusion.
