CN101024423A - Buffering safety apparatus for airborne forces super-low space quick bail-out soft landing - Google Patents

Abstract

The invention relates to a minimum altitude rapid bailout safety protecting device. It creates high pressure jetting reacting force, hydraulic reaction thrust, and magnetic repulsion force. The control combination integrated safety protecting device would make airborne forces bouncing 5 meters after landing. Thus, the gravity acceleration couple would be avoided. Thus, it would avoid being injured caused by staying in air for too long time.

Description

A kind of buffering safety apparatus of airborne forces super-low space quick bail-out soft landing

1. application category: it is to be used for the Decklevel parachute jump field of landing fast, can break through the safety guard of tradition warning limit minimum altitude.

2. technical background: traditional parachutist's parachute jumping is then should be less than 300 meters (not being commonly called as critical dead height) at 600 meters take-off opening altitudes in theory, also increase day by day because of parachutist's equipment its load capacity of change especially with modernization, the acceleration due to gravity that it produces airborne back is particularly surprising, have to go reply to improve jumping altitude in order to ensure safety, consequent negative effect (having prolonged the landing time) it all can bring accidental disaster will for unit and paratrooper like this! " space-time " control of modern war is to seize every minute and second, and soldier's life direct line is in this.In addition owing between time-delay landing provides abundance to take aim at will for the other side's firepower to fan the air, in other words, uphanging the airborne ground-surface rake object of living that then becomes.From retrieval, do not find as yet to parachute and break through extreme low-altitude prompt drop record below 300 meters the paratrooper.

3. summary of the invention: be chosen as and shorten the landing time and take to reduce and think limit warning height and be to parachute under the area situation of parachute not increasing in theory, this is kind of an excessive risk behave beyond doubt.If do not possess a chain of complete overall prediction scheme of reply of a cover and produce cover security shock absorber with strong complementarity, and even will pay high cost life.The present invention is based on above-mentioned the hows and whys aims at its " acceleration/accel " and solves a problem, createing the reasonably overall prediction scheme of a cover deals with, it is multiple class compound type, it is again the complementary safety protection device of energy, " extreme low-altitude fast parachuting " can be guarded against below the height in the limit to carry out, it has shortened the landing quality time, personal safety is ensured, be to be objective use the integrated innovative approach of multiple combination by antagonistic force jet flow, the magnetic that three kinds of class different structure principles constitute push away, hydraulic boosting and fast the security prediction scheme measure of a chain of control of inflatable packer inflation being finished.Actual content:＜1 〉: being linked with 2 pressure by airborne personnel's both legs is 60-80 atmosphere cold gas cylinder, can do sth. in advance about 5 seconds air valve (3) to be opened, thereby by gaseous blast ground to be produced antagonistic force by its feeler lever that lands (2) before landing lands.＜2 〉: by two pairs of permanent magnets be separately fixed at two legs other and one with slide rail on the feeler lever (6) early of landing on the leg high-end, so, make the strong magnetic pole generation thrust of repelling each other because it is movable to constitute " deciding ", " moving " two magnet apart from diminishing.＜3 〉: utilize hydraulic efficiency pressure system will land feeler lever (7) in advance as promoting notes plug pump piston and pressure being passed to human body by pipeline.Height about 5 meters rebounds again after these three kinds of power impel the paratrooper to land jointly; with impedance by the airborne acceleration due to gravity couple that begins to produce; playing buffer action makes " extreme low-altitude fast parachuting " be able to security; except also set up a sensor (8); it can remind the chutist with the form of signal flasher: if when accident is arranged (referring to fault); still can use a handgrip (9) of remedying usefulness by spurring cable wire and open air valve (3) by force by lever with hand-tight holding; and a small-sized umbrella (11) can also be opened rapidly; simultaneously can also open little air bottle (10) with security inflatable packer (12) fast aeration under the sole; next guarantees the safety of parachuting as last line of defense about utilizing whiff pressure with the high about 5M of human body bullet.

4. the specific embodiment is as follows:

＜1〉being linked with 2 pressure at airborne personnel's both legs is the 60-80KG barometric pressure, the cold high pressure gas cylinder (1) of the about 400-500 milliliter of capacity, it can do sth. in advance about 5 times in second by its feeler lever that lands (2) before landing, air valve (3) is opened, the feeler lever landing instant eject about 80 atmospheric air-flows it with respect to ground on about 3 square centimeters of area soils, remove to promote human body (comprise and bear load) spring liftoff 3-5 rice height that raises again after feeler lever lands thereby produce antagonistic force.

＜2〉adopt " magnetic pushes away " mode to make one pair of fixed with moving two blocks of powerful permanent magnet (4), (5) its pole orientation is what repel each other, it is other and have on the feeler lever that lands in advance (6) high-end of slide rail that it is separately fixed at two legs, feeler lever can contact to earth in advance when landing and slide to the upper edge slide rail owing to land, thereby can reduce distance between " deciding ", " moving " two blocks of magnet, thereby produce forced-ventilated repulsion, moment can be elected the overhead 3-5 rice height that bounces with human body.

＜3〉utilize feeler lever (7) that hydraulic efficiency pressure system will land in advance as the piston that promotes to annotate the plug pump, it is given pressure transmission human body and makes its jump help by pipeline, also can be with human body bullet 3-5 rice height overhead.

Remove the above safety protection device that forms by three kinds of different textural associations of class different principle and also enclose a sensor

(8); it reminds the chutist with the form of signal flasher: if when accident is arranged (referring to fault); still can use remedy usefulness a handgrip (9) it by tightly spurring cable wire and open air valve (3) by force by shouldering bar with holding; and a small-sized umbrella (11) can also be opened rapidly simultaneously; certainly this umbrella wants little many compared with main parachute; and small-sized air bottle (10) (60 barometric pressures; 250 milliliters of capacity) with the inflatable packer under the sole (12) fast aeration, and about utilizing whiff pressure with the high about 5M of human body bullet.All these measures all are purposes---the acceleration due to gravity couple that the high-altitude landing time is produced resists resistance, and it highly only has 3-5 rice high when landing after spring again, and this brief acceleration can have been ignored, and this difficult problem also just has been readily solved.This measure can make the degree of risk of extreme low-altitude fast parachuting reduce greatly, has also won valuable time for personal safety.

＜4〉drawing explanation: Figure of description compiles 1, is 2 air bottles that are linked with on the both legs.2, be two feeler levers (sensing) that land at first.3, be the air valve of two air bottles.4～5, be two pairs of strong magnets.6, for below the magnet with the feeler lever that lands of slide rail.7, be the hydraulic efficiency pressure system feeler lever that lands, promote to annotate plug pump with its and drive upwards spring of human body.8, be the sensor of indicator lamp.9, hold the cable wire pull bar for what remedy usefulness.10, be the little air bottle of underfooting security inflatable packer inflation usefulness.11, be small-sized umbrella.12, be the fast aeration pad.
