[0002] With the development of aircraft technology, it has become more difficult for pilots to escape when the aircraft is damaged. Especially when flying at high speeds, the ejection seat may cause secondary damage due to excessive rocket thrust.

Therefore, countries are strengthening the research and development of ejection seats, and simulator training helps pilots learn the correct escape techniques to improve escape efficiency and success rate.

[0003] A Chinese patent discloses a VR-based ejection life-saving training system with application number CN201822034519.8.

During ejection training, the pilot sits on the ejection seat body 31 and is located in the simulated cockpit 22. When the ejection program is started, the ejection seat body 31 slides upward along the ejection guide rail 322 on the ejection release mechanism 32. When the ejection seat body 31 slides to the top of the ejection guide rail 322, the pilot holds the gripping device 43 of the parachute system 4, and the parachute system 4 is started. The first linear drive device 42 drives the suspension device 41 to move on the frame 1. At this time, the gripping device 43 takes the pilot away from the ejection seat body 31 to complete the simulated training of ejection parachuting.

[0024] The frame 1 includes: a support arm 11, an upper cross frame 12 and a lower cross frame 13. Four support arms 11 are provided. The support arm 11 connects the upper cross frame 12 with the lower cross frame 13. An ejection zone is formed between the support arm 11, the upper cross frame 12 and the lower cross frame 13. A simulated cockpit device 2 is installed at the bottom of the ejection zone, and a suspension device 41 is installed on the upper cross frame 12. The frame 1 is used to fix the relative positions of the simulated cockpit device 2, the seat ejection system 3, the parachute system 4 and other simulation devices to ensure that the pilot completes the simulation training safely in the frame 1.

[0025] The simulated cockpit 22 includes: a cabin, a joystick, pedals and an operating instrument panel. The cabin is installed on the landing platform 21. The joystick, pedals and operating instrument panel are all arranged in the cabin. An ejection release mechanism 32 is installed on one side of the operating instrument panel. The ejection seat body 31 on the ejection release mechanism 32 can be surrounded by the cabin, joystick, pedals and operating instrument panel. Pedals are arranged on the bottom of the cabin. The pedals are located below the operating instrument panel. There are two pedals. The joystick is located between the pedals. The operating instrument panel is electrically connected to the monitoring system. The operating instrument panel is used to operate the ejection mode. The cabin, joystick and pedals mainly simulate the appearance and angle of the actual installation of the carrier-based aircraft. The operating instrument panel is used for the pilot to visually view the various data and parameters of the current flight. At the same time, the ejection escape procedure can be started under the condition that the training requirements are met.

[0026] The ejection disengagement mechanism 32 includes: a base 321, an ejection guide rail 322, and a pneumatic system 323. The base 321 is installed on the landing platform 21. The base 321 is hinged to one end of the ejection guide rail 322. The pneumatic system 323 is installed between the base 321 and the ejection guide rail 322. The pneumatic system 323 is used to drive the ejection guide rail 322 to rotate relative to the base 321. The axis around which the ejection guide rail 322 rotates relative to the base 321 is located in the Z direction. The ejection guide rail 322 is slidably connected to the ejection seat body 31. A second linear drive device 325 is connected between the ejection guide rail 322 and the ejection seat body 31. The pneumatic system 323 can adjust the inclination angle of the ejection guide rail 322 relative to the base 321, so that the pilot can adjust different angles for ejection according to the training requirements, so as to complete the pilot's escape training in different postures of the aircraft during flight.

[0027] The pneumatic system 323 includes a first telescopic cylinder and a second telescopic cylinder, one end of the first telescopic cylinder is hinged to the base 321, and the other end of the first telescopic cylinder is hinged to the ejection guide rail 322, one end of the second telescopic cylinder is hinged to the base 321, and the other end of the second telescopic cylinder is hinged to the ejection guide rail 322, there is a distance between the first telescopic cylinder and the second telescopic cylinder, that is, the first telescopic cylinder and the second telescopic cylinder are arranged at an interval, the lengths of the first telescopic cylinder and the second telescopic cylinder are different, the first telescopic cylinder and the second telescopic cylinder cooperate with each other to control the extension length under the control of the monitoring system, and then adjust the inclination angle of the ejection guide rail 322, that is, the ejection angle.

[0028] The ejection seat body 31 includes: a seat body 311 and a sliding mechanism 312. The seat body 311 is provided with a seat portion and a backrest portion. The back of the backrest portion is connected to the sliding mechanism 312. The sliding mechanism 312 is slidably connected to the ejection guide rail 322. The sliding mechanism 312 is connected to the second linear drive device 325. When the ejection procedure is started, the second linear drive device 325 drives the sliding mechanism 312 to make the seat body 311 slide quickly on the ejection guide rail 322 to simulate the escape process of the seat body 311 ejecting from the cockpit.

[0029] The sliding mechanism 312 includes: a sliding frame 3121 and a sliding wheel group 3122. The sliding frame 3121 is fixed to the backrest of the seat body 311, and the sliding wheel group 3122 is installed on the sliding frame 3121. The side of the ejection guide rail 322 protrudes to form a guide block 3123, and the guide block 3123 is clamped by the sliding wheel group 3122. The sliding frame 3121 slides on the ejection guide rail 322 together with the seat body 311, and the guide block 3123 limits the sliding area of ​​the sliding frame 3121 on the ejection guide rail 322 to prevent the sliding frame 3121 and the seat body 311 from being separated from the ejection guide rail 322 during the sliding process.

[0030] The second linear drive device 325 includes: a second drive motor 3251, a first bevel gear, a second bevel gear, a traveling gear 3252 and a rack 3253. The second drive motor 3251 is mounted on the sliding frame 3121. The output end of the second drive motor 3251 is fixed to the first bevel gear, and the second bevel gear is meshed with the first bevel gear. The second bevel gear is fixed to the coupling, and the coupling is connected to the traveling gear 3252. The rack 3253 is meshed with the traveling gear 3252. The rack 3253 is fixed on the ejection guide rail 322, and the rack 3253 is parallel to the guide block 3123. When the ejection program is started, the second drive motor 3251 is started to rotate the first bevel gear, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the traveling gear 3252 to rotate on the rack 3253 through the coupling, and drives the seat body 311 to slide on the ejection guide rail 322 to simulate the seat ejection process.

[0031] There are two sets of second bevel gears, couplings, travel gears 3252, racks 3253, guide blocks 3123 and sliding wheel groups 3122, and the two sets of second bevel gears, couplings, travel gears 3252, racks 3253, guide blocks 3123 and sliding wheel groups 3122 are symmetrically arranged on both sides of the second drive motor 3251. The second drive motor 3251 drives both ends of the sliding frame 3121 to slide synchronously on the ejection guide rail 322, so as to prevent the seat body 311 from tilting during the sliding process, resulting in unsmooth sliding and causing safety hazards.

[0032] The ejection life-saving whole process simulation training system also includes: VR glasses, which are worn by trainees and are connected to the monitoring system in communication; so the ejection life-saving whole process simulation training system performs training operation according to the following steps: S1, the trainees sit on the ejection seat body 31; S2, the trainees watch the operating instrument panel, flight visual simulation and all-terrain as well as ejection life-saving simulation scenes through VR glasses; S3, the trainees issue an ejection start command by operating the simulated cockpit 22, and the ejection start command includes: start command information, ejection angle information and ejection distance information, the ejection distance information is the distance from the initial position to the ejection position of the ejection seat body 31, and the monitoring system obtains the ejection start command Command; S4, the ejection separation mechanism 32 drives the ejection seat body 31 and the trainee to eject from the cabin, and the ejection separation mechanism 32 drives the ejection seat body 31 and the trainee to the designated position according to the ejection angle information; S5, the trainee performs the seat and parachute switching operation (that is, the process of the trainee switching from the ejection seat body to the suspension parachute), the trainee moves and grabs the grasping device 43 to achieve the separation of the person and the chair, and the ejection seat body 31 is driven to descend by the ejection separation mechanism 32; S6, the trainee performs the parachute operation; S7, the trainee reaches the landing platform 21 through the parachute system 4 to complete the training; S8, the monitoring system makes an ejection life-saving operation evaluation based on the training data of the trainee. Since the switch between ejection training and parachute training is made by grasping the grasping device 43, there is a risk that the trainee fails to grasp the grasping device 43 and falls off the ejection seat body 31 during the switch. Therefore, in step S4, it is necessary to calculate the position that the grasping end of the grasping device 43 in the parachute system 4 should reach to adapt to the grasping action of the trainee who is ejected to the ejection position. Then how to calculate the position that the grasping end of the grasping device 43 should reach when adapting to the ejection position is a problem that should be solved later.

[0033] The gripping device 43 includes: a gripping rope, a winch and a gripping ring. The winch is installed on the suspension device 41. The winch is electrically connected to the monitoring system. The winch winds up the high end of the gripping rope, and the low end of the gripping rope is fixed to the gripping ring. The gripping ring is the gripping end of the gripping device 43. The winch can be reeled in under the control of the monitoring system to control the suspension height of the gripping ring.

[0034] like Figure 3As shown, in step S4, while the ejection separation mechanism 32 is running, the monitoring system controls the operation of the parachute system 4 according to the operation of the ejection separation mechanism 32, and the monitoring system controls the operation of the parachute system 4 in the following steps: S41, the monitoring system calculates the operation data of the parachute system 4, and the calculation steps are as follows: S411, obtain the ejection angle information a, the ejection distance information d0; S412, set the initial position of the ejection seat body 31 as the origin, the initial position of the ejection system is (x0, y0), and calculate the ejection position (x1, y1) reached by the ejection seat body 31; S413, calculate the position (x2, y2) reached by the parachute system 4 after ejection according to the trainee's height h and the ejection position (x1, y1); S414, calculate the running distance d1 of the first linear drive device 42 in the parachute system 4 to drive the suspension device 41 according to x2 and x0, and calculate the lifting distance d2 of the gripping end of the gripping device 43 according to y0 and y2; S42, the monitoring system controls the first linear drive device 42 to drive the suspension device 41 to run the distance d1, and the monitoring system controls the lifting distance d2 of the gripping end of the gripping device 43. In order to adapt to the position that the gripping end of the gripping device 43 should reach at the ejection position, the position that the gripping end of the gripping device 43 should reach is: the position (x2, y2) reached by the parachute system 4. The purpose of the above steps is to calculate the position (x2, y2) reached by the parachute system 4.

[0035] In step S412, x1=-d0×cos a, y1=d0×sin a; step S413 includes the following steps:

[0036] S4131. Before the training begins, several tests are conducted. In each test, the trainee sits on the ejection seat body. The ejection separation mechanism 32 drives the ejection seat body 31 to the ejection position (x1, y1), and then drives the first linear drive device 42 and the gripping device 43 of the parachute system 4, so that the trainee at the ejection position can grip the gripping end of the gripping device 43. The position (x2, y2) reached by the parachute system 4 is recorded. In several groups of tests, the height h of the trainee is different.

[0037] S4132, perform statistical fitting processing on the ejection position (x1, y1) and the position (x2, y2) reached by the parachute system after ejection, and obtain x2=x1+i0+i1h+i2h 2 +i3h 3 (Formula 1), y2=y1+j0+j1h+j2h 2 +j3h 3 (Formula 2), i0, i1, i2, i3, j0, j1, j2 and j3 are all constants after statistical fitting;

[0038] S4133. Count the vertical distance d4 and horizontal distance d5 between the hand and the body when trainees of different heights h perform hanging grasping movements;

[0039] S4134. Assume that the thickness of the ejection seat body is d7, calculate the horizontal thickness of the ejection seat body d6, d6 = d7 × sina;

[0040] S4135, calculating the difference △x and △y, including the following steps: first, substituting the ejection position (x1, y1) and the height h in the test of step S4131 into Formula 1 and Formula 2 respectively, to obtain the first prediction x2 and y2; then, using the vertical distance d4 and the horizontal distance d5 to calculate the second prediction x2' and y2', x2'=x1+d6+d5, y2'=y1+d4; finally, calculating △x=x2-x2', △y=y2-y2';

[0041] S4136, calculate the average value of N groups of △x and the average value of △y S4137, Utilization Modify formula 1 and get the final calculation formula of x2: use Modify formula 2 and get the final calculation formula of y2:

[0042] S4138. Substitute the height h and ejection position (x1, y1) of the current real-time training personnel into Formula 3 and Formula 4 respectively to obtain the position (x2, y2) reached by the real-time parachute system.

[0043] In the upper step, two kinds of statistics are performed: the first one is to simulate the test of the ejection seat body 31 grasping the gripping device, and after the test, the relationship between (x2, y2), h and (x1, y1) is obtained by statistics, and at least 5 groups of (x2, y2), h and (x1, y1) test data are used to fit the relationship; the second one is to directly count the distance between the hand and the shoulder of people of different heights during the grasping action, and obtain the vertical distance d4 and the horizontal distance d5, and use (x1, y1), the thickness of the ejection seat body d7, the vertical distance d4 and the horizontal distance d5 to obtain the formula for calculating x2 and y2. Both statistical methods have their own reasons. Through the combination of the two statistical methods, with the first statistical method as the main method and the second statistical method as the auxiliary method, the average difference of the two statistical methods is used to correct the calculation formula of the first statistical method, so as to obtain the final calculation formula three and formula four, which fully utilizes the mutual relationship, so that the trainee on the ejection seat body 31 can better grasp the gripping end of the gripping device 43.

[0044] In formula 3, the default value of x2 is a negative value. Since x1 is a negative value, i0+i1h+i2h2 +i3h 3 is a positive value, so the formula used in formula 3 In formula 4, it is assumed that the value of y2 is a positive value. Since y1 is a positive value, j0+j1h+j2h 2 +j3h 3 is a positive value, so the formula used in formula 3 Avoid the ejection seat body 31 gripping the gripping device 43 during the test process to obtain a higher y2, the difference If it is a positive value, it will cause the height to be too high and inconvenient to grasp. The human body instinctively grasps to the highest point within the range of the shoulder, and the grasping suspension action is normal.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
