Description

The invention relates to the field of airborne training of personnel and can be used in simulators for hypoxic training of paratroopers for high-altitude landing.

The parameters of the Earth's atmosphere at various altitudes are known [1]. According to GOST 4401-81, at a height of 0 meters above sea level, the pressure is 760 mm Hg. (101325 Pa), and at an altitude of 10,000 meters 198 mm Hg. (26499.9 Pa). The temperature at an altitude of 0 meters above sea level is plus 15°C, and at an altitude of 10,000 meters it is minus 49.89°C.

The parameters of pressure control in the cargo compartment of the Il-76MD military transport aircraft, which is used as a standard aircraft for parachute landing, including high-altitude landing, personnel and equipment of the Armed Forces of the Russian Federation, are known [2]. With normally operating air conditioning and automatic pressure control systems, at an aircraft flight altitude of 12000 meters, the pressure in the cabins (crew, cargo and stern) corresponds to a flight altitude of 3200 ± 300 meters, the barometric pressure is 512 mm Hg.

There are known requirements for airborne training for high-altitude jumps (from 4000 to 10000 m) in the Earth's atmosphere [3].

In accordance with the “Guidelines for operations with free fall” [3], the body of a skydiver experiences changes in ambient temperature, pressure changes and hypoxia during prolonged stay at high altitude, the physiological training and condition of skydivers performing high-altitude jumps should allow them to perform their tasks.

Cigarette smoking, alcohol and medication use (including antihistamines, sedatives, and analgesics), fatigue, and anxiety can lead to increased hypoxia susceptibility.

A parachutist subject to hypoxia may lose consciousness and therefore be unable to complete the task assigned to them, for example, put into operation (open) a parachute at a given height or pilot a parachute system to a given point.

Before performing a high-altitude landing (from altitudes from 5400 to 10000 meters), the paratrooper performing it needs to carry out preliminary breathing (from 30 to 60 minutes) with a mixture of gases (air mixture) in order to reduce the nitrogen content and increase the oxygen content in the blood. In addition, after leaving the aircraft, the skydiver will also use oxygen equipment during the jump.

Problems connecting or switching oxygen equipment can lead to an increase in nitrogen in the skydiver's blood and therefore an increased likelihood of decompression sickness.

A skydiver suffering from decompression sickness may die or become permanently disabled due to nitrogen bubbles in the bloodstream.

Considering all this, a parachutist performing high-altitude landing with a parachute system must have extensive knowledge and skills to maintain his performance, conduct regular realistic training for physiological training, and develop practical skills.

The effect of hypoxia on the human body, the causes of its occurrence in pilots of aircraft, its consequences, as well as ways of human adaptation to it are known [4,5].

Hypoxia is an insufficient amount or inability to use enough oxygen to saturate the hemoglobin in the blood and meet the metabolic needs of the body. The main threat to pilots and high-altitude paratroopers is hypobaric hypoxia. This form of hypoxia is experienced by people trying to breathe in conditions of oxygen deficiency. As a person rises from the surface in the Earth's atmosphere, the atmospheric pressure decreases non-linearly, and with it the partial pressure of oxygen. When such a deficiency as the lack of oxygen in the blood becomes significant, it is quickly followed by loss of consciousness. In flight, this phenomenon can occur instantly or gradually.

Hypoxia can occur due to two different causes, either due to depressurization of an aircraft at high altitude as a result of a sudden loss of pressure, for example, the opening of the ramp of a military transport aircraft at an altitude of more than 3048 meters (10,000 feet) in which case hypoxia will occur instantly. Or, in the absence of pressure maintenance in the aircraft cabin at an altitude above 3048 meters (10,000 feet), with the sealing and pressure control system turned off or malfunctioning, in this case, hypoxia will come gradually.

With systematic exposure to moderate hypoxia, intracellular adaptation reactions are triggered in each cell. This systemic and cellular restructuring underlies the stimulating effect, allows you to restore the normal activity of human organs and tissues under conditions of limited oxygen delivery and adapt a person to hypoxia.

There is a known method and system of high-altitude training based on virtual reality [6].

The method consists in that the user selects a virtual high-altitude scene in the high-altitude scene database (which includes data for modeling weather conditions (wind force, temperature), the selected three-dimensional panoramic image corresponding to the selected virtual high-altitude scene is displayed on a virtual display device. The user uses a wearable receiver, which in real time captures changes in the user's facial expression, body position, limbs and generates a control action with a change in height, landscape and other objects of a virtual high-rise scene.

The disadvantage of this method is that it provides only visual adaptation of the user and does not allow his physical and physiological adaptation.

There is a known method and system for altitude adaptation [7]. The controls in the room regulate the ratio of oxygen and carbon dioxide in accordance with the calculated environmental conditions at a given height. The trainee performs fitness loads, in particular on a treadmill, in a room with an adjusted ratio of oxygen and carbon dioxide.

The recording device captures the results of the fitness of the trainee to a given height when performing the specified fitness loads.

Data on height, weight, body fat, blood pressure, pulse, lung volume and lung function, oxygen concentration in peripheral vessels, maximum oxygen uptake, grip strength of the hand (static force), dynamic endurance of the abdominal muscles are used as data for analyzing the fitness of the trainee. , shoulder strength and others. As a result of the analysis of the obtained data, a conclusion is issued on the suitability of the trainee to a given height.

The disadvantage of this method is, firstly, that it does not provide the trainee's adaptation heights required for high-altitude landing (from 4000 to 10000 meters), and secondly, the fitness loads performed by the trainee do not provide the formation of the skills necessary for high-altitude landing (parachute introduction into work and its piloting).

A known method of protecting the crew from hypoxia, which consists in increasing the partial pressure of oxygen in the air mixture supplied for breathing to each crew member [8].

The disadvantage of the method of protecting the crew from hypoxia is the insufficient protection of crew members from the development of circulatory hypoxia under the action of rapidly increasing positive longitudinal (relative to the body of a crew member) overloads.

Closest to the claimed method, that is, the prototype, is the flight training method and the device that implements it [9].

The method consists in the fact that the trainee (learner) takes a place in the simulator, which allows working out the functional skills of working with the equipment components located inside the flight training chamber. Additionally, the trainee (student) is put on means of monitoring physiological parameters.

The trainee (learner) begins to perform tasks by acting on the simulator controls that imitate the controls of the simulated object.

At the required moment of time, coordinated with the task being performed, the trainee (learner) is provided with the onset of hypoxia.

At the same time, he continues to perform the task on the simulator.

The onset of the effect of hypoxia and the removal of the trainee (trainee) from it is realized at predetermined points of the flight task.

External observation of the actions of the trainee (learner) and his condition is carried out by a video camera and means of monitoring physiological parameters.

The data from the simulator, together with the data from the video cameras and means of monitoring physiological parameters, are sent to the control unit, where they are jointly processed, after which a physiological and / or cognitive assessment of the trainee (student) is carried out.

The disadvantages of this method is that it does not provide training actions trainee (learner) when exposed to negative ambient temperature in the event of depressurization of the aircraft.

In FIG. 1 shows a diagram of a flight training device that implements the prototype method.

The device for implementing the prototype method consists of a chamber (1) which has an inlet air intake and outlet and is equipped with equipment for preparing, supplying, circulating the gas mixture inside the chamber (air, oxygen, oxygen-nitrogen mixture).

Outside the chamber (1) there is a control unit (8).

The chamber (1) can be made in the form of a hypobaric or normobaric chamber.

The external view of the flight training device is shown in Fig. 3 and 4.

The operation of the device according to this method is as follows.

In the embodiment of the chamber (1) in the form of a normobaric chamber, the trainee (trainee) (4) takes a place in the flight simulation system of the aircraft (2), puts on a mask (5) and a means of monitoring the physiological parameters of the trainee (trainee) ( 6).

According to the results of the analysis, the control unit (8) at the time required for adequate simulation of the flight of the aircraft, by the flight simulation system of the aircraft (2) or according to the indications of the means of monitoring the physiological parameters of the trainee (trainee) (6), or the video camera (7) issues a command hypoxicator (3), which begins to supply the trainee (trainee) (4) through the mask (5), oxygen or gas mixture to stop the trainee (trainee) (4) from hypoxia.

According to the results of the trainee (trainee) (4) completing the flight simulation of the aircraft on the flight simulation system of the aircraft (2), the trainee (trainee) (4) removes the means of monitoring the physiological parameters of the trainee (trainee) (6), the mask (5) from the respiratory paths and leaves the flight simulation system of the aircraft (2), and the control unit (8) gives an assessment of the readiness of the trainee (student) (4) for actions to perform the flight of the aircraft in hypoxia.

In the embodiment of the chamber (1) in the form of a hypobaric chamber, the trainee (trainee) (4) takes a place in the flight simulation system of the aircraft (2), puts on the mask (5) and a means of monitoring the physiological parameters of the trainee (trainee) ( 6).

The control unit (8) runs a program that controls the equipment located in the chamber (1), controls the supply of the gas mixture and analyzes the data coming from the flight simulation system of the aircraft (2), the hypoxicator (3), the means for monitoring the physiological parameters of the trainee (student ) (7), video cameras (7).

At the command of the control unit (8), the flight simulation system of the aircraft (2) is launched, the hypoxicator (3) through the mask (5) supplies the trainee (trainee) (4) with air, and the chamber equipment (1) (equipment for preparation, supply, circulation of the gas mixture) lowers the pressure and supplies the chamber (1) with a gas mixture, inducing a state of hypoxia in the trainee (trainee) (4) at the time required for adequate simulation of the flight of the aircraft, by the flight simulation system of the aircraft (2).

The trainee (trained) (4) removes the mask (5) from the respiratory tract and, on the flight simulation system of the aircraft (2), performs the flight plan of the simulated aircraft.

The video camera (7) captures the external state of the trainee (trainee) (4) and the actions performed by the trainee (trainee) (4) on the flight simulation system of the aircraft (2) and also transmits them to the control unit (8).

According to the results of the analysis, the control unit (9) at the time required for adequate simulation of the flight of the aircraft, by the flight simulation system of the aircraft (2) or according to the indications of the means of monitoring the physiological parameters of the trainee (student) (6), or the video camera (7) issues a command hypoxicator (3), which begins to supply the trainee (trainee) (4) through the mask (5), oxygen or a gas mixture to stop the trainee (trainee) (4) from the state of hypoxia or maintain it.

According to the results of the trainee (trainee) (4) completing the flight simulation of the aircraft on the flight simulation system of the aircraft (2), the trainee (trainee) (4) removes the means of monitoring the physiological parameters of the trainee (trainee) (6), the mask (5) from the respiratory paths and leaves the flight simulation system of the aircraft (2), and the control unit (8) gives an assessment of the readiness of the trainee (student) (4) for actions to perform the flight of the aircraft in hypoxia.

The disadvantage of the device is, firstly, that it does not provide altered pressure drops experienced by a paratrooper during high-altitude landing, and secondly, the absence of a backup system for monitoring the state of a trainee (trainee) can lead to death, in case of failure or incorrect operation of the equipment, thirdly, the aircraft flight simulation system does not provide the formation of the correct skills and the consolidation of complex coordination actions of a parachutist during jumps with long delays in introducing the parachute system into operation.

The invention is based on the task of individual adaptation and preparation for high-altitude landing of military personnel of special forces units of the Armed Forces of the Russian Federation due to the development of the necessary related skills and actions before and after depressurization of the cargo compartment of the aircraft at altitudes of more than 3200 meters, due to the opening of the ramp for high-altitude landing .

To achieve this goal, the following is additionally introduced into the prototype method:

- preparation of a trainee (trainee) (4) to leave the aircraft, implemented by high-altitude landing;

- imitation of indications by a trained (trained) (4) aircraft by high-altitude landing;

- blowing air during the simulation jump;

- acoustic reproduction of the sound picture of noises identical to the noises generated by the aircraft when the ramp is opened;

- change in atmospheric pressure during the simulation of leaving the aircraft, implemented by high-altitude landing in accordance with the simulated altitude of the trainee (trained) (4).

To prepare the trainee (trainee) (4) to leave the aircraft, during high-altitude landing, the air pressure in the chamber is reduced to 512 mm Hg. and maintain it at a given level for 30 to 60 minutes (depending on the simulated landing height). Provide maintenance of oxygen in the blood of the trainee (learner) (4) at the required level, in the same time interval as the ambient pressure.

Also, to simulate the impact of a negative ambient temperature on a trainee (learner) during landing, a refrigerant is mixed into the streams of blown air.

Using sensors that record the impacts made by a trained (trained) skydiver on the control devices of a controlled (gliding) parachute parachute system, the software generates a change in virtual space and body position in the simulator, simulating the movements of a parachutist in the air from the moment of leaving the aircraft (hereinafter LA) before landing.

Software tools based on 3D simulation create a virtual space, the cargo compartment of the aircraft, the opening ramp of the cargo compartment of the aircraft and free space (air and ground conditions, time of day, season, terrain).

The picture of the virtual space is brought to the trainee (learner) (4).

Together with the picture of the virtual space, there is airflow and acoustic reproduction of the sound picture of noises identical to the noises generated by the aircraft when the ramp is opened.

To simulate the impact of a negative ambient temperature on a trainee (trainee) (4) during the simulation when opening the ramp and high-altitude landing, a refrigerant is mixed into the streams of blown air.

At the same time, the atmospheric pressure in the chamber is from 512 mm Hg. lower to a value of 405 mm Hg. up to 198 mm Hg, corresponding to the height simulated by the simulator, and maintained at a given level until the required moment, corresponding to the indication by the trained (trained) (4) of the cargo compartment of the aircraft and the start of high-altitude landing.

At a point in time coordinated with the simulated altitude in a 3D simulation of a virtual space simulating a jump with a controlled (gliding) parachute system, the pressure in the chamber under the control of the software increases from 198 mm Hg (corresponding to an altitude of 10,000 meters) to 760 mm Hg. Art. (corresponds to a height of 0 meters).

Based on the incoming data from the camera and sensors, the actions of the trainee (trained) (4) are assessed, both during preparation for a simulated jump with a controlled (planning) parachute system, and during its execution.

The device that implements the proposed method is shown in Fig. 2 and consists of interconnected newly introduced hypobaric chamber (9) with airlocks, airborne training simulator (10), acoustic system (11), air flow generation system (12), instructor (teacher) (13), oxygen device (14), light and sound signaling (15), video recording systems (16), monitoring and control systems (17).

The appearance of the device that implements the proposed method is shown in Fig. 5.

The proposed device that implements the proposed method operates as follows:

The equipped trainee (trainee) (4) takes the place of the chamber (1) made in the form of a hypobaric chamber, puts on the respiratory tract a mask (5) of a portable oxygen device (14) and a means of monitoring the physiological parameters of the trainee (trainee) (6).

The monitoring and control system (17) starts a program that controls the pressure in the chamber (1). The pressure in the chamber (1) is reduced to 512 mm Hg. and support him.

The trainee (trained) (4), through the mask (5) gives out the gas mixture coming from the oxygen device (14) during the time specified by the high-altitude landing plan (from 30 to 60 minutes). As the trainee (learner) (4) spends, he changes oxygen devices (14).

The monitoring and control system (17) starts a program that controls the pressure in the hypobaric chamber (9). The pressure in the hypobaric chamber (9) decreases from 405 mm Hg. up to 198 mm Hg depending on the simulated landing height from 5400 to 10000 meters.

Entering the hyperbaric chamber (9), due to the pressure difference with the chamber (1) and the hyperbaric chamber (9) and the oxygen content, the trainee (trainee) (4) is subjected to hypoxia.

At the command of the light and sound alarm (15) associated with the monitoring and control system (17), equipped with a mask (5), trained (trained) (4), the hypobaric chamber (9) enters through the gateway and takes a place in the air- airborne training (10), connects the mask (5) to the oxygen device (14) included in the airborne training simulator (10).

The operation of the airborne training simulator (10) is monitored and controlled by the control and management system (17).

On command from the monitoring and control system (17), the air flow generation system (12) blows the trainee (trainee) (4) with air flows mixed with refrigerant, simulating air flows when the ramp is opened and during high-altitude landing, and the acoustic system ( 11) reproduces a changing sound picture of noise, identical to the noise generated by the aircraft when the ramp is opened.

The trainee (learner) (4) acting on the controls of the airborne training simulator (10) and observing a three-dimensional image of the virtual world, performs a flight task, practicing the tasks of the jump (opening height, piloting, approaching the landing point, etc.).

As the trained (trained) (4) in the virtual world of simulated high-altitude landing decreases, the pressure in the hypobaric chamber (9) increases from the initial 198 mm Hg. - 405 mm Hg up to 760 mm Hg when simulating a landing.

Means for monitoring the physiological parameters of the trainee (student) (6) receive data on the physiological parameters of the trainee (trainee) (4) and transfer them to the monitoring and control system (17).

The video fixation system (16) captures the external state of the trainee (trainee) (4) during his stay in the chamber (1), the gateway of the hypobaric chamber (9), the hypobaric chamber (9) and the actions performed by the trainee (trainee) (4 ) on the airborne training simulator (10) and also transfers them to the control and management system (17).

The data received in the monitoring and control system (17) from the airborne training simulator 10), the means for monitoring the physiological parameters of the trainee (trainee) (6), the video recording system (16), are jointly processed and analyzed and issued to the instructor (teacher) ( 13).

After completing the flight task on the airborne training simulator (10) (landing), the trainee (trainee) (4) removes the mask (5) from the respiratory tract, the means of monitoring the physiological parameters of the trainee (trainee) (6) and leaves the simulator amphibious training (10) and exits the hypobaric chamber (9) through the airlock.

According to the results of the trainee (trainee) (4) performing actions in the chamber (1) and actions on the airborne training simulator (10), the control and management system (17) gives an assessment of the trainee (trainee) (4), which is communicated to the instructor ( teacher) (13).

Also, the assessment of the actions of the trainee (trainee) (4) can be carried out by the instructor (teacher) (13) manually according to the video recording system (16), control and management system (17).

The proposed method of training paratroopers, in contrast to the prototype method, allows solving the problem by ensuring that the trained (trained) actions are identical to the actions performed by a paratrooper when performing a real high-altitude landing, that is, performing preliminary breathing with a mixture of gases (air mixture) in atmospheric cargo cockpit of an aircraft identical to natural, the onset of hypoxia when simulating the opening of the ramp of the cargo compartment of an aircraft due to a sharp change in pressure when passing through the airlock to the hypobaric chamber, a change in pressure in the hypobaric chamber relative to the simulated landing height, blowing the trained (trained) air flow with a coolant, acoustic reproduction of the sound picture of noises identical to the noises generated by the aircraft when the ramp is opened, makes it possible to develop related skills in preparing for high-altitude landing, high-altitude landing, practicing the actions of the trainee (trainee) in hypoxia, to increase the integrated preparedness of the trainee (trainee) by working out the entire sequence of actions and increase adaptability to the effects of the environment.

The proposed device, in contrast to the device that implements the method of the prototype, makes it possible to practice skills in working with oxygen equipment in the process of preparing for high-altitude landing and its completion, parachute control skills in the process of jumping with a parachute system, increase preparedness for the effects of hypoxia when performing high-altitude landing, technical result, which consists in the possibility of working out related actions to control the parachute system, oxygen equipment in conditions of changes in atmospheric pressure and hypoxia.

Based on the foregoing, the proposed method and technical solution make it possible to solve the problem, and for its practical implementation, serially mastered models of equipment can be used, such as the KUDESNIK LUIK.161464.001 airborne training simulator, portable oxygen device KP- 19 or KP-21, oxygen mask KM-32 and light and sound signaling equipment AZS1K-5 of the Il-76 military transport aircraft, hypobaric chamber HYPO (Altitude) Chamber by BAROKS Hyperbaric)) (Turkey).
