Description
Technical field
The present invention relates to a kind of push-pull effect imitator and control method thereof.Described push-pull effect imitator be a kind of utilize adjustable positive subnormal ambient to the aircrew carry out cephalopodium to acceleration change due to the simulation training special implement of hemodynamics variation.
Background technology
Along with development of aviation and aerospace technology, how high-quality pilot and spacefarer become and press for, and it is essential that this makes that supporting pilot and astronaut training's facility become.At present, the training facilities that the aircrew uses is the negative pressure cabin basically, and the aircrew places oneself in the midst of in the negative pressure cabin of simulation aeronautical environment, carries out the training of high-altitude physiology, weary oxygen endurance and ear air pressure function, nasal sinuses air pressure function.The training of correct footward acceleration can only rely on large-scale human centrifuge to train.Adopt the defective of this training in existing negative pressure cabin to be, can not simulate that the suffered cephalopodium of aircrew changes to acceleration in the practical flight.And the human centrifuge can not simulate the push-pull effect in the practical flight, promptly can not closely follow a zooming air battle process behind quick the decline in the simulated flight.Moreover large-scale human centrifuge's equipment heaviness involves great expense, complicated operation, and maintenance difficulties is big, is difficult to realize general instruction and refreshment regularly.
Summary of the invention
The object of the present invention is to provide a kind of push-pull effect imitator and control method thereof, in order to overcome negative pressure cabin and human centrifuge's above-mentioned defective.Technical problem to be solved is, first, according to the aerial acceleration syncope phenomenon that the aircrew very easily occurs in practical flight, can carry out special training; The second, can simulate push-pull effect in the practical flight, the zooming aerial combat maneuver after promptly descending fast immediately following has acclimatization training; Three, realize pilot's health and simulator cabin body import and export contact position are sealed, when pilot's waist and waist place with the lower part in the body of simulator cabin, when waist placed simulator cabin body in addition with top, simulator cabin body was in good sealing state.
In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme.
A kind of push-pull effect imitator comprises the main cabin body that has import and export, and its special feature is: be provided with the pressure balance case in the body of main cabin, this pressure balance case is circumscribed with vacuum pump by trachea; Be provided with air bottle, it is connected with main cabin body by trachea; Also comprise be used for pilot's health with import and export the sealing device seal; Its sealing device comprises the gas-flow closure circle that is connected with seat belt, and seat belt is connected the top of gas-flow closure circle; Periphery at the gas-flow closure circle is connected with a circle rubber bellows, and the lower end of gas-flow closure circle is connected with annular rubber washer.
Described air bottle places beyond the body of main cabin.
At the pressure balance upper box part seat cushion that the pilot uses is installed.
It is spigot joint that the gas-flow closure circle is provided with inflation; Seat belt is buckled with the gas-flow closure circle by above trousers and is linked together.
The control method of described push-pull effect imitator, its special feature is: on the body of main cabin controller is installed, the switch of control solenoid-operated proportional control valve and each direct-acting electromagnetic valve; During the power-on switch, vacuum pump is in running order all the time;
When needing negative pressure in the body of main cabin, the knob on the controller is screwed into the negative pressure position, the solenoid-operated proportional control valve and first direct-acting electromagnetic valve are opened, and second direct-acting electromagnetic valve and the 3rd direct-acting electromagnetic valve are closed, and are communicated with between pressure balance case and the main cabin body;
When needing malleation in the body of main cabin, knob on the controller is screwed into the malleation position, solenoid-operated proportional control valve and second direct-acting electromagnetic valve are opened, and first direct-acting electromagnetic valve and the 3rd direct-acting electromagnetic valve are closed, and are communicated with between air bottle and the main cabin body and import gas to the latter;
When needing to recover the pressure need adjustment of normal pressure or cabin in the body of main cabin, knob on the controller is screwed into the normal pressure position, solenoid-operated proportional control valve and the 3rd direct-acting electromagnetic valve are opened, first direct-acting electromagnetic valve and second direct-acting electromagnetic valve are closed, when reaching force value in the cabin, knob on the controller is screwed into back zero position, and solenoid-operated proportional control valve, first direct-acting electromagnetic valve, second direct-acting electromagnetic valve and the 3rd direct-acting electromagnetic valve all are in closed condition at this moment.
Good effect of the present invention is, (1), aircrew's waist and waist are in the body of cabin with the lower part, change by positive negative pressure in the cabin changes systemic blood kinetics, after the positive negative pressure of varying strength is trained after a while, can effectively improve the adaptability of blood vessel, reduce the incidence rate of aerial acceleration syncope.(2), supporting high-pressure air source and the vacuum pump of being provided with, pass through control system, make cabin internal pressure environment in 1～5 second time, reach the force value of setting, simulated in the practical flight immediately following the zooming air battle process after the quick decline process, realize desired training objectives, reduce the incidence rate of fainting due to the push-pull effect.(3), enter the cabin below pilot's waist after, gas-flow closure circle inflation with body import and export edge, simulator cabin sealing, therefore, adopts the sealing device, has realized that effectively the trainer advances the sealing problem in cabin.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of sealing device of the present invention.
The specific embodiment
As shown in Figure 1, manufacturing one has the main cabin body 1 of import and export 2 and vent valve 10, establishes a pressure balance case 3 in the main cabin body 1, and pressure balance case 3 is two autonomous container with main cabin body 1.The seat of a sponge leather cushion as the trainer installed on pressure balance case 3 tops.Pressure balance case 3 is circumscribed with vacuum pump 4 by trachea; Be provided with air bottle 5, it is connected with main cabin body 1 by trachea.Described pressure balance case 3 and air bottle 5 place beyond the main cabin body 1.
Import and export 2 at main cabin body are provided with an elasticity air inflation sealing device, and as shown in Figure 2, sealing device of the present invention is mainly by seat belt 11, gas-flow closure circle 12, rubber bellows 13, rubber washer 14 and inflate spigot joint 15 5 parts and form.Wherein gas-flow closure circle 12, rubber bellows 13 and rubber washer 14 3 parts are formed by three different Mold Makings respectively, and being bonded together by seccotine between the three then forms the main body of sealing device.Seat belt 11 is buckled with gas-flow closure circle 12 by five trousers and is linked together, and inflates spigot joint 15 and adopts fluid sealant and gas-flow closure circle 12 to bond together.The annular mouth of rubber washer 14 and simulator cabin body are imported and exported 2 shapes, consistent size, work in coordination.The entity part of rubber washer 14 is by on the bulkhead that is bolted to simulator master cabin body 1.
