Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of flight training, and in particular to an illusion simulation guiding method based on autonomous flight control. BACKGROUND
[0002] Flight illusion refers to the incorrect perception of the state, position, direction, motion and flight environment of the pilot and the aircraft during flight, which is an important personnel factor leading to flight accidents; it is particularly prone to occur during high-performance fighter maneuvering flight, night flight and sea surface flight. Flight illusion training is an effective method to improve illusion awareness and reduce flight accidents, including real aircraft flight experience training and ground simulation training. Both need to design process scenarios according to different illusion characteristics to enable pilots to experience the illusions induced during the flight process.
[0003] Flight illusion simulation training has the characteristics of high efficiency, high safety and low cost, and is the development trend of current illusion simulation training. Illusion simulation training provides pilots with more illusion experience training opportunities, thereby improving illusion awareness and vigilance.
[0004] Currently, in flight illusion simulation, the integrity of spatial orientation information is limited, and the training is carried out through passive experience or instruction flight. Passive experience refers to allowing the trainee pilot to experience the motion and visual stimulation of the flight process passively without operating the aircraft, thereby inducing flight illusion; instruction flight refers to the trainee pilot actively operating the aircraft according to the flight operation instructions, thereby inducing flight illusion. The specific flight operation process is usually performed according to voice or visual instructions.
[0005] Disadvantages of the prior art:
[0006] 1. The illusion training using passive experience method has insufficient immersion, which affects the enthusiasm of the pilot in participating in the simulation training and the recognition of the training results to some extent; the reason is that the trainee pilot does not participate in flight operation, but only experiences the external flight environment stimulation as a "passenger", and cannot fully associate flight actions with feelings;
[0007] 2. The flight actions performed by the pilot using the instruction listening method have large differences, which leads to inaccurate induction scenes and poor simulation effect; the reason is that the instructions cannot be accurately quantified, and each trainee pilot has different understanding, reaction time and execution of the instructions, which leads to large training condition dispersion and low training result consistency;
[0008] 3. Too much or too detailed flight target instruction, inevitably provides directional information to the trainees, which affects the flight control of the trainees, reduces the illusion induction rate, and affects the training effect; the cause is that the instruction itself inevitably contains target flight information or flight action prompt information, which affects the spatial orientation judgment of the trainee pilots.
[0009] Therefore, it is necessary to develop an illusion simulation guidance method based on autonomous flight control to solve the above problems. SUMMARY
[0010] The purpose of the present application is to design an illusion simulation guidance method based on autonomous flight control to solve the above problems.
[0011] The present application realizes the above-mentioned purpose through the following technical solutions:
[0012] An illusion simulation guidance method based on autonomous flight control, comprising:
[0013] Step 1: Designing simulation flight trajectory and flight action according to simulation target illusion scene;
[0014] Step 2: Generating target flight trajectory action parameters for simulation aircraft:
[0015] Step 3: Informing the trainee pilots to control the aircraft before the training starts, and flying the target aircraft by visual flight close following; wherein the target aircraft refers to the lead aircraft of the formation flight or the locked target aircraft;
[0016] Step 4: Configuring simulation visual environment; the simulation visual environment conditions meet the visual target aircraft conditions of the trainee pilots, and have spatial orientation information;
[0017] Step 5: After the simulator system is ready, configure the same take-off site and initial speed, and at the same time, unfreeze and start flying, the trainee pilots follow the target aircraft by close tracking; after starting to fly, the target aircraft flight trajectory action uses the record in step 2, and the trainee pilots real-time control their own aircraft for tracking;
[0018] Step 6: Real-time acquisition of target and trainee pilot aircraft data for real-time analysis and evaluation of tracking conditions and giving prompts to guide the trainee pilots to adjust the tracking state of flight control and ensure tracking consistency:
[0019] 1) In the flight process, the trainee pilot controlled aircraft trajectory and target aircraft flight parameter trajectory, speed, attitude, and flight time error are acquired, the tracking condition is evaluated in real time, and the evaluation calculation method includes error absolute value weighting and fuzzy classification;
[0020] 2) When the position error or attitude error exceeds the threshold, the tracking state is fed back to the trainee pilot through pictures and audio prompts, guiding the trainee pilot to adjust the tracking amplitude to a relatively reasonable range;
[0021] Step 7: Analyzing the illusion situation during flight, the analysis includes the following ways:
[0022] 1) Way 1: At the key point, ask the trainee pilot about the current flight state of the aircraft, including flight speed, position, and attitude, and judge whether the trainee pilot has flight illusion by the accuracy of the answer;
[0023] 2) Way 2: At the key point, instruct the trainee pilot to give up the target and immediately change to a specific flight state mode, including level flight, and judge whether the trainee pilot has flight illusion by checking the rationality of the flight control executed by the trainee pilot;
[0024] Wherein, the key point refers to after the maneuver flight prone to flight illusion, the maneuver flight prone to flight illusion includes long time circling, slope, and rapid change of attitude angle;
[0025] Step 8: After determining that the pilot has illusion, guide the pilot to restore spatial orientation through flight instruments and visual scenes, and give voice prompts to explain the illusion situation.
[0026] The beneficial effects of the present application are:
[0027] In steps 1-2, according to the illusion simulation requirements, the simulation flight trajectory and specific flight actions are designed in advance, and then the target aircraft flight parameters meeting the above requirements are generated; in steps 3-6, the target aircraft guiding mode is adopted to let the trainee pilot himself manipulate the aircraft to perform near-distance high-accuracy flight tracking, inducing the trainee pilot to enter the illusion scene and flight illusion state through autonomous flight; in steps 7-8, the trainee pilot feedback state correctness or maneuver flight action execution rationality is used to judge and prompt the flight illusion induction situation at the key point; this method allows the trainee pilot to complete the illusion simulation target flight action and flight trajectory with high fidelity under autonomous manipulation, improving the consistency of the flight simulation scene. Secondly, the trainee pilot always has flight targets that constantly change the flight state during training, and the target trajectory prompt is given to avoid target loss; this method adjusts the attention of the trainee pilot to a highly concentrated state, further improving the flight illusion induction rate and training effect.

[0035] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0036] like Figure 1 As shown, an illusion simulation guidance method based on autonomous flight control includes the following steps:
[0037] Step 1: Design the simulated flight trajectory (start position, heading, etc.) and flight maneuvers (such as level flight, circling, somersault, roll, and compound maneuvers) according to the simulated target illusion scene;
[0038] Step 2: Generate target flight trajectory motion parameters by software or manual control of the simulated aircraft:
[0039] 1) Record flight parameters during flight;
[0040] 2) Record flight parameters at least including: time information, longitude, latitude, altitude, and other position information, yaw, pitch angle, roll angle, and other attitude information.
[0041] Step 3: Before training, inform the trainee pilot to control the aircraft, and fly close to the target aircraft / vehicle by visual flight. The target aircraft refers to the aircraft in formation flight (lead aircraft) or the locked target aircraft.
[0042] Step 4: Configure the simulated visual environment: the simulated visual environment conditions should meet the visual target aircraft conditions for the trainee pilot, and should have less spatial orientation information, such as low visibility, no obvious or even invisible horizon, etc.
[0043] Step 5: After the simulator system is ready, configure the same take-off location and initial speed in the simulator software, and unfreeze the start of flight, the trainee pilot follows the target aircraft by close tracking;
[0044] 1) After starting flight, the target aircraft flight trajectory and attitude use the flight trajectory recorded in step 2, and the trainee pilot controls his own aircraft in real time to track;
[0045] 2) The target aircraft can be multiple aircraft in formation flight, and the flight trajectories of the related aircraft group can be translated to form a formation based on the flight trajectories recorded in step 2;
[0046] 3) The visual scene of the guidance system has a flight path display function, within a certain period of time after the target aircraft flies, the trainee pilot can see the target flight path prompt information through the visual scene, so as to master the flight direction and attitude of the target aircraft, and avoid losing the target;
[0047] 4) The above prompt information has depth change function, expressing distance and flight time information; has closable attitude expression function, expressing the attitude of the target aircraft when it flies over.
[0048] Step 6: The guidance system contains a set of tracking evaluation system (data analysis hardware and software), which obtains the data of the target and the trainee pilot's aircraft in real time, for real-time analysis and evaluation of tracking situation and gives prompt, guiding the trainee pilot to adjust the flight control and track state, ensuring the consistency of tracking:
[0049] 1) In the process of flight, the tracking evaluation system obtains the trajectory of the aircraft operated by the trainee pilot and the target aircraft trajectory, speed, attitude, flyover time error, and other flight parameters, and evaluates the tracking situation in real time. The evaluation calculation method includes error absolute value weighting, fuzzy classification, and other methods;
[0050] 2) When the position error or attitude error exceeds the threshold value, the tracking state is fed back to the trainee pilot through pictures and audio prompts, guiding the trainee pilot to adjust the tracking amplitude to a relatively reasonable range;
[0051] 3) The tracking evaluation includes multiple levels of threshold values, and the prompts are also different accordingly.
[0052] Step 7: Analyze the illusion situation during flight, which includes the following methods
[0053] 1) Method 1: At key points, ask the trainee pilot about the current aircraft flight speed, position, attitude, and other flight states. Through the accuracy of the trainee pilot's answers, determine whether he has flight illusion;
[0054] 2) Method 2: At key points, instruct the trainee pilot to abandon the target and immediately change to a specific flight state (such as changing to level flight, changing to 10° right slope, or other actions). By checking the reasonableness of the trainee pilot's flight maneuvers, determine whether he has flight illusion;
[0055] Among them, the key points are after the maneuver flight that is easy to cause flight illusion, such as long-time circling, slope, and rapid change of attitude angle.
[0056] Step 8: After determining that the pilot has illusion, guide the pilot to gradually restore spatial orientation through flight instruments and visual scenes, and give voice prompts to explain the illusion situation and improve awareness. If the trainee pilot is not comfortable due to illusion, stop training;
[0057] Note: Under the condition that the instructor has sufficient flight skills, the target aircraft can also be flown by the instructor in real time.
[0058] The above is only a preferred embodiment of the present application. It should be noted that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, several improvements and refinements can be made, which should also be considered as the protection scope of the present application.
