Description
Technical Field
The application relates to the technical field of flight simulation, in particular to an oblique flight illusion simulation method.
Background
The illusion of flight, also known as a spatial orientation disorder, is the incorrect perception of the position, attitude, direction and movement of the aircraft or itself by the pilot while in flight. The illusion of flight is one of the most important factors in serious flight accidents related to human factors, and is common among flight personnel, so that the flight efficiency of pilots is influenced, and the flight safety is compromised. In general, the human body mainly relies on its own vision, vestibular sensation, proprioception to perform spatial orientation, and determines its own state and position. When a pilot flies in the air, the human body has a certain limitation on six-freedom complex motions in the air and limited visual scene conditions due to the physiological functions of the human body's own sense organs and the central nervous system motion perception modes, so that the occurrence of the illusion of flying can be caused. Complex weather such as cloud, fog, rain, snow and the like encountered in flight, linear acceleration and angular velocity stimulation in flight, night flight, offshore flight and the like are all important factors for inducing the illusion of flight.
The illusion of inclination is the illusion of the pilot on the slope of the aircraft, is one of common and high-incidence flight illusions, and mainly shows that the pilot feels the slope of the aircraft when the aircraft actually flies flat or turns horizontally; while the aircraft is actually flying with a slope, the pilot feels that the tilt illusion can be induced by vestibular proprioception information on flat flights or over-or under-estimation of the slope. In the related art, the scheme for overcoming the illusion of oblique flight is generally a conventional method for effectively performing space orientation and overcoming the illusion of flight according to the visual instrument flight. In daily flight, various flight illusions can be generated by the flight personnel due to certain external factors and internal factors of the flight personnel, but if the flight illusions are depended on reliable and correct directional information sources, the flight illusions can be effectively overcome, for example, according to the instrument flight, and the flight accidents are avoided.
The instrument visual space orientation is the most reliable orientation information source in flight, but relative to visual orientation information such as heaven, earth, landmarks and the like, the instrument visual space orientation has the problems of indirection, instability and the like, if the instrument flight technique is unskilled, the flight illusion cannot be recognized and identified, the instrument visual space orientation is difficult to play an effective role, and the flight illusion can occur to cause the flight accident. Therefore, the oblique flight illusion experience training is developed on the flight illusion simulator, so that pilots are helped to recognize, identify and correctly handle the flight illusions, and the oblique flight illusion experience training is an effective method for effectively reducing the rate of flight accidents caused by the illusions.
In a general oblique flight illusion simulation method based on a flight illusion simulator, if trained personnel observe a flight instrument in time, the slope abnormality of the aircraft can be found and corrected earlier, so that the success rate of the oblique flight illusion simulation is lower. Therefore, in the improved oblique flight illusion simulation method, the plane horizon instrument and the plane display are turned off or frozen before illusion occurs, instrument orientation information is reduced or stopped from being provided for trained personnel, and the trained personnel mainly rely on the vestibular proprioception system to carry out spatial orientation so as to improve the success rate of oblique flight illusion simulation. However, the improved method has the problems of inconsistent display state of an actual flight instrument, influence on immersion of a simulated flight task, low fidelity and strength of inclination illusion of trained personnel, and the like.

The embodiment of the application provides an oblique flight illusion simulation method which is used for the above-mentioned flight illusion simulator, and by setting a flight subject and complex meteorological conditions, coriolis acceleration is generated to stimulate a vestibular sense organ of a pilot, so that the pilot experiences and correctly recognizes oblique flight illusions in the process of executing a simulated flight task.
As shown in fig. 2, a flow chart of the coriolis illusion simulation method provided by the application includes the following steps:
step 201, receiving a setting operation of flight parameters by a training person, and generating a target flight task.
The target flight mission may include, but is not limited to: daytime complex meteorological flight tasks. The preset complex weather conditions may include, for example, but are not limited to, any of the following: in-cloud flight, over-cloud flight with cloud cover >40%, under-cloud flight with visibility <5km, etc.
Referring also to fig. 1, illustratively, the trainee may implement an input operation of the flight parameters through an interaction module in the management system 105 in the flight illusion simulator 100, and the flight illusion simulator 100 generates a target flight mission according to the received setting operation of the flight parameters. The preset meteorological parameters corresponding to the target flight mission are set in the flight illusion simulator 100 as visibility 3km, cloud cover is 60%, the cloud base height is 2000 m, and Yun Hou-3000 m. The target flight mission may be selected as a complex weather flight mission and the time may be selected as daytime. The aircraft type, airport territory, etc. may be selected by themselves based on configuration options associated with the illusion simulator 100, which is not limiting in this embodiment of the application.
By setting the target flight task in the mode, when a pilot flies, the pilot cannot see the landmark, the ground line which is referred by the visual space orientation is disappeared, the outside view cannot provide a movement clue, the pilot can generate space orientation difficulty, and then the vestibular illusion is easily induced under the condition that the pilot relies on the vestibular sensory system to orient more.
And 202, sending first flight indication information to trained personnel, so that the trained personnel can finish take-off operation according to information displayed by an instrument display system under the indication of the first flight indication information and keep flying flatly after reaching a preset height.
The predetermined height is greater than the cloud height, for example, the predetermined height is preferably greater than 3000 meters.
And 203, sending second flight indication information to the trained personnel, so that the trained personnel can enter a horizontal continuous turn in a flat flight stage according to the information displayed by the instrument display system under the indication of the second flight indication information.
The trained personnel enter a horizontal continuous turn in a flat flight stage and can roll to the maximum gradient of 30 degrees to the right or left rapidly with the angular acceleration above the human body feel threshold value, and the altitude is kept.
Specifically, referring to fig. 1, the six-degree-of-freedom motion platform 102 may be controlled to drive the simulation cabin 101 to roll to the right or left by a set angle, and at the same time, the 360-degree continuous rotation platform 103 is controlled to drive the simulation cabin 101 to slowly accelerate to the right or left to a set angular velocity with an angular acceleration below the human body feeling threshold, and then continuously rotate at a constant speed.
Illustratively, after the aircraft has completed the takeoff phase and entered a predetermined altitude for flat flight, the trained personnel rapidly rolls to the right (or left) to 30 ° maximum grade with an angular acceleration above a human perception threshold (e.g., the threshold is 0.5o/s 2) and maintains altitude.
In this process, the six-degree-of-freedom motion platform 102 is controlled to slowly pitch up by a set angle with an angular acceleration lower than the human body feeling threshold, and at the same time, the 360-degree continuous rotation platform 103 is controlled to slowly accelerate to the right or left by an angular acceleration lower than the human body feeling threshold to a set angular velocity, and then continuously rotate at a constant speed.
For example, the six degree-of-freedom motion platform 102 is controlled to roll the simulation pod 101 15 ° to the right (or left) with an angular acceleration above the human sensory threshold. Then, the six-degree-of-freedom motion stage 102 is controlled to slowly pitch up by 15 ° at an angular acceleration below the human sense threshold, while the 360-degree-continuous-rotation stage 103 is controlled to slowly accelerate to the right (or left) to 20 °/s at an angular acceleration below the human sense threshold. During this process, the trainee in the cabin cannot feel to pitch up around the horizontal axis and to rotate continuously to the right (or left) around the vertical axis, consistent with the actual flight experience.
And 204, sending third flight indication information for quickly changing gradient flight into flat flight to the trained personnel, so that the vestibular sensing organ is subjected to Coriolis acceleration in the cabin rolling process of the trained personnel, and an oblique flight illusion is generated.
Illustratively, after the aircraft enters a 45-degree right (or left) slope for turning and flying for 60 seconds, the trained personnel operate the aircraft to rapidly roll 45 degrees to the left (or right) according to the horizon or the head up display indication information, and the horizontal flying attitude is restored. In the process, the six-degree-of-freedom motion platform is controlled to drive the simulation cabin to pitch downwards around a pitching axis by a certain angle from a pitching position in a set time, so that the simulation cabin is restored to a neutral position. For example, the six-degree-of-freedom motion platform 102 is controlled to drive the simulation cabin 101 to pitch down by 15 ° around the pitch axis from the upward-pitch position within 2s, so that the simulation cabin 101 is restored to the neutral position. At this time, the pilot rotates around the second axis, namely the pitching axis, while rotating around the vertical axis at 20 °/s rightward (or leftward), the vestibular sensory system of the pilot receives coriolis acceleration, and generates a strong sense of tilting while rolling around the third axis, namely the rolling axis, leftward (rightward), consistent with the sense of tilting illusion in actual flight.
And step 205, sending fourth flight indication information to the trained personnel so as to enable the trained personnel to gradually eliminate the oblique flight illusion.
The fourth indication is used for indicating the trained personnel to trust the instrument parameters and keep flying flat.
Illustratively, an instruction is issued to the trainee instructing the pilot to trust the instrument parameters to continue to remain flat for 60 seconds. In the process, the 360-degree continuous rotation platform 103 is controlled to drive the simulation cabin 101 to slowly decelerate to stop rotation at an angular acceleration lower than the human body feeling threshold. When the rotation of the simulation cabin 101 around the pitch axis is stopped, the coriolis acceleration applied to the trainee is eliminated, and the illusion of flying inclined to the left (or right) of the body is gradually reduced and eliminated.
According to the oblique flight illusion simulation method provided by the application, the flight illusion simulator is utilized, and the Coriolis acceleration is generated to stimulate the vestibular feel organ of the pilot by setting the flight subjects and the complex meteorological conditions, so that the pilot experiences and correctly recognizes the oblique flight illusion in the process of executing the simulated flight task.
Compared with a common oblique flight illusion simulation method, the scheme of the application has the advantages that the space orientation of trained personnel is less influenced by instrument orientation information, the inducing success rate is high, and the fidelity and strength of oblique flight illusions are higher.
