Abstract

The invention relates to a multiitem safety protection device for extreme low-altitude rapid parachuting. As traditionally specified, the high-altitude jump-out distance is 600M, the parachute opening distance is not lower than 300M, a paratrooper or an athlete needs to overcome the acceleration influence and the upward dragging force generated in a moment of opening a parachute in order to challenge the limit and strive for time and space. According to the multiitem safety protection device disclosed by the invention, a small ball umbrella is automatically opened when the paratrooper or the athlete leaves from a window, then a main parachute is pulled to be open in a two-umbrella transitional manner, and therefore, the area of the main parachute which is smaller than the conventional parachute can be selected. A gravity sensor fuse (gunpowder) is used for enabling the human body to be ejected upwards to 1-2M (off the ground), and no influence of acceleration is caused when the human body descends again. A damping device consisting of a spring and oil or gas is adopted to be synchronously combined with the main parachute in different directions, a reverse force couple is generated in the moment of opening the parachute against the dragging force, and therefore the injuries to the human body are reduced.

Description

The multinomial safety guard that a kind of extreme low-altitude fast parachuting is used

1. application category: it is for aviation Decklevel parachute jump land fast military and sports field, can break through traditional safety guard of guarding against limit minimum altitude.

2. technical background: traditional parachutist's parachute jumping is then should be less than 300M (not being commonly called as critical dead height) at 600M take-off opening altitude in theory, and at present international minimum record is 284M.Also increase day by day because of parachutist's equipment its load capacity of change with modernization especially, it increases the airborne rear acceleration due to gravity that produces especially, 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 rake object of living that then becomes ground.Not yet find to be lower than when paratrooper and parachutist perform the extreme low-altitude prompt drop record of 284M from retrieval, before 5 years, U.S.'s parachute club Beijing of coming on invitation is done the Decklevel parachute jump performance and is learned from each other by exchanging views.The result is not providing in new technical equipment and other countrmeasure situations, his set a record (critically limit height) is 298M, at this moment, the Chinese athlete generally feel the rib astigmatism frame equally feel bad (in the first moment of parachute-opening), nearly two weeks also recovers not come over.

3. summary of the invention: be chosen as and shorten the landing time and take to reduce opening altitude and think on the traditional theory that the limit warning highly is 300M, if do not take to increase the area feelings of parachute, reduce again highly to be undoubtedly and plant an excessive risk behave.On the other hand, large because extreme low-altitude its density of air is relatively wanted, therefore it is also more much bigger than the bungee jumping campaign in the burst " drag force " that strand of human body is made progress at parachute-opening moment parachute.It brings grievous injury to chutist's physical and mental health, and the reverse damping arrangement that is combined into by spring and oil or gas that will design targeted specifically for this reason that a cover can contend with it makes it produce that downward counteraction couple contends with " drag force " flexibility that makes progress and is that out-phase is synchronous by being connected in series with main parachute.If do not possess the security shock absorber with strong complementarity of the multinomial chain of rings of a cover, and even will pay high cost life.The present invention is based on above-mentioned the hows and whys and deal with except " acceleration/accel " 1G * deadweight is overcome difficulties, also create the reasonably overall prediction scheme of a cover for it, it is the prior art combination of multiple class, 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, should be with the integrated innovative approach of multiple combination by three kinds of class different structure principle＜1 to be objective〉as load onto one " reverse damper assembly " device (being formed by spring and oil or gas) its similarities and differences step be serially connected on the main parachute it be by (A) section-gentle district and (B) synthetic " drag force " couple in section-hard area done optimum accounting point and just can guarantee that it is making progress " drag force " of the burst type that produces parachute-opening moment of contending with of buffer-type at this moment that the first moment of parachute-opening is played the excellent damping effect, sees the vectorial diagram of accompanying drawing 2.Next is that the antagonistic force fuse launches, magnetic pushes away, hydraulic boosting and fast the inflatable packer inflation is connected the measure of ring control type security and finish.＜2〉open the bead umbrella that at first automatically to open an inflation after the jumping, and then open main parachute, its effect is to reach to select outside the conventional main parachute that will be less that compares upwards " drag force " that produced owing to moment by a little parachute-openings.＜3 〉: airborne personnel are equipped with steel plate and fuse ejection system (similar ready-made fighter plane launches parachute device automatically) under the buttocks seat, can be before landing prior to human body landing " back taper " weight contact (2) of being balanced by weight sensor second of 3-5 ahead of time, because straw line elastic recoil, make by playing capacity contacting discharge and go the fuse emission energy that human body and the whole empty of loading with are upwards penetrated approximately 1-2M height (this measure aim at the acceleration action before eliminating and establish), simultaneously air valve (4) is opened.＜4 〉: by two pairs of permanent magnets (4), (5) be separately fixed on the contrary two legs with magnetic pole other with slide rail (6) upper and lower end, so because it is movable can make " decide ", " moving " two magnet apart from diminishing, make the strong magnetic pole generation thrust of repelling each other.＜5 〉: in parachute jumping personnel underfooting two inflatable safety pads (12) are installed.Height about 2M can rebound first after above these three kinds of power impel the paratrooper to land jointly, to eliminate the acceleration due to gravity couple that is begun to produce by airborne, the universal experience formula adopts quality * 9.8, key is that Decklevel parachute jump must not be that " whenever holding up an umbrella " otherwise 9.8 times of gravity will be smashed to pieces, key be should seize every minute and second perfectly safe again.Playing buffer action makes " extreme low-altitude fast parachuting " be able to security.＜6 〉: set up a sensor (8); it can remind the chutist with the form of signal flasher: if (refer to fault) when accident is arranged; still can use a handgrip (9) of remedying usefulness by holding to spur cable wire and open by force air valve (3) by lever with hand-tight; and a small-sized umbrella (11) can also be opened rapidly; can also open little air bottle (10) with security inflatable packer (12) fast aeration under the sole this moment; also can remedy the cushioning effect of landing again behind the high approximately 1-2M of human body bullet; fall (providing lift by the ball umbrella) as for delaying again later on, guarantee that as last line of defense parachute jumping safety escapes injury.

4. the specific embodiment is as follows:

＜1〉when jumping out of aircraft window, airborne personnel to have the facility of the bead umbrella of automatically opening to guarantee

＜2〉its " back taper " contact (2) that can land in advance about 3-5 time second it is driven by cable wire by its weight sensor in landing, interaction energy makes the capacitive strike fuse that human body is upwards launched approximately 1-2M height, with air valve (4), make two safety air cushions in underfooting (12) inflation.Below all be to carry out automatically control via obtaining the data programmed after the experiment.

＜3〉adopt " magnetic pushes away " mode to make two blocks of powerful permanent magnets (4) of a pair " fixed and moving ", (5) making its pole orientation is what repel each other, be separately fixed at the other high-end place with slide rail (6) of two legs, feeler lever can contact to earth in advance when landing and pass through the hydraulic boosting upward sliding owing to landing, thereby can reduce distance between " deciding ", " moving " two blocks of magnet, thereby produce forced-ventilated repulsion, moment can upwards be elected human body and is the overhead a kind of Double safety device of 1-2M height power-assisted that bounces.

＜4 〉: produced the counteraction couple because " reverse damper assembly " device that overlaps " the anti-drag force " of with it phase containing being housed simultaneously in extreme low-altitude parachute-opening.

Except above different by multiple class; the safety protection device that the totally different textural association of principle forms is also enclosed a sensor (8) outward; it reminds the chutist with the form of signal flasher: if (refer to fault) when accident is arranged; still can use remedy usefulness a handgrip (9) it by tightly spurring cable wire and open by force air valve (3) by lever 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) is with the inflatable packer under the sole (12) fast aeration.All these measures all are purposes---the acceleration due to gravity couple that produces when making the high-altitude landing gives anti-resistance (overcoming difficulties), and it highly only has 1-2 rice high when landing after spring again, the acceleration/accel that lands again this moment has not existed, and this difficult problem also just has been readily solved.This measure can make the degree of risk of extreme low-altitude fast parachuting greatly reduce, and has also won the most valuable time for personal safety.

＜5 〉: the drawing explanation: Figure of description 1 compiles 1, is 2 air bottles that are linked with on the leg.Compiling (2), is the heavy contact of two back tapers that land at first of weight sensor.Compiling 3, is the air valve of two air bottles.Compiling 4～5, is two pairs of strong magnets.Compiling (6), is with the feeler lever that lands of slide rail below the magnet.Compiling (7), is the hydraulic efficiency pressure system feeler lever that lands, and promotes piston pump with its and drives upwards spring of human body.Compiling (8), is the sensor of indicator lamp.Compile (9), be remedy usefulness hold the cable wire pull bar.Compiling (10), is the little air bottle of underfooting security inflatable packer inflation usefulness.Compiling (11), is small-sized umbrella.Compiling (12), is the fast aeration pad.Compiling (13), is ejection system.

Figure of description 2 is that " anti-drag force " and " drag force " of " reverse damping " assembly is in the diagram of parachute-opening moment vector.Wherein the interval accounting point selection of A, B is that the damping success or failure are crucial, must just can obtain a result with experiment, after parachute-opening past moment, " drag force " no longer existed, because damper assembly is connected in series with the main chute disjunctor, therefore return to normal (being permanent attitude), it only plays connection function.At this moment, " anti-drag force " couple just can not produce yet.
