Abstract

The invention relates to a safety protection device for extreme low-altitude fast parachuting and soft landing. The height of conventional high jump is specified as 600 meters and parachute-opening height is higher than or equal to 300 meters; and in order to challenge the limit and strive for space time, paratroopers and athletes need to overcome 1, the effect of accelerated speed; and 2, upward 'pull force' generated at the parachute-opening moment. In the safety protection device, a small ball parachute automatically opens firstly when the paratroopers or the athletes jump out of an aircraft window, and then a main parachute is opened in a transient mode of the two parachutes, and thus the main parachute of which the area is smaller than that of the conventional main parachute can be selected; a gravity sensor fuse (gunpowder) is adopted, so that a human body is ejected upwards to 3 to 5 meters, and then the human body is not influenced by the accelerated speed when landing again; and a damping device consisting of springs and oil or gas is adopted to combine with the main parachute in a mode of inverted synchronization, and 'inverted force couple' can be generated at the parachute-opening moment to contend against 'the pull force', so that the damage to the human body is reduced.

Description

The safety guard that a kind of extreme low-altitude fast parachuting and soft landing is used

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 the critically limit height) at 600 meters take-off opening altitudes in theory, and international minimum record at present is 284M.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 increases 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 also 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 be lower than 284 meters extreme low-altitude prompt drop records, if adopt this patent can reduce the limit to 200M even lower paratrooper and parachutist's performance.

3. summary of the invention: be chosen as shorten the landing time and take to reduce think in theory the limit the warning height and also be to parachute under the area situation of parachute not increasing, this is kind of an excessive risk behave beyond doubt.On the other hand big because extreme low-altitude its density of air is relatively wanted, so parachute-opening moment to that strand of human body make progress " drag force " much bigger compared with the bungee jumping campaign! It brings grievous injury will be connected in series " drag force " that make it produce downward counteraction couple and make progress with main parachute by the reverse damping arrangement of being made up of spring and oil or gas that can contend with it at ground design one cover to chutist's body and mind for this reason and contends with and be that out-phase is synchronous.If do not possess a whole set of a chain of complete security shock absorber with strong complementarity 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 that the rational totally prediction scheme of a cover that also creates of overcoming difficulties for its " acceleration/accel " 1G * deadweight, 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, be to be objective use the integrated innovative approach of multiple combination by three kinds of class different structure principles and since be equipped with one " reverse damper assembly " device (forming) out-phase by spring and oil or gas synchronous be serially connected in main parachute " drag force " that make progress that parachute-opening moment produced that get on to contend with, and the antagonistic force fuse launches, magnetic pushes away, hydraulic boosting and fast the security measure of all a chain of controls such as inflatable packer inflation being finished.Actual content:＜1〉should open a gas filed bead umbrella at first automatically after opening jumping, and then open main parachute, its effect is can select for use outside the conventional main parachute that will be littler that compares, and can also be subjected to a little parachute-openings less because " the upwards drag force " that moment produced when opening main parachute.＜2 〉: airborne personnel are equipped with steel plate and fuse ejection system (the automatic ejection bailout device of similar ready-made fighter plane) under the buttocks seat, can before landing, do sth. in advance " back taper " weight contact (2) that 3-5 is balanced by weight sensor second prior to human body landing, because straw line elastic recoil, make by large bulk capacitance contacting discharge and go the fuse emission energy that human body and the whole empty of loading with are upwards penetrated about 3 meters height (this measure aim at the acceleration action before eliminating and establish), simultaneously air valve (4) is opened.＜3 〉: by two pairs of permanent magnets (4), (5) are separately fixed at the other upper and lower end with slide rail (6) of two legs on the contrary with magnetic pole, 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.＜4 〉: 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.＜5 〉: two inflatable safety pads (12) are installed in parachute jumping personnel underfooting.More than these three kinds of power height about 3 meters that can rebound earlier after impelling the paratrooper to land jointly, to eliminate the acceleration due to gravity couple that begins to produce by airborne, the universal experience formula adopts matter heavy * 9.8, key is that Decklevel parachute jump must not be that " not 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 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 insurance 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 about 3M of human body bullet, fall (providing lift) as for delaying again later on, guarantee that as last line of defense parachute jumping safety escapes injury by the ball umbrella.

4. the specific embodiment is as follows:

＜1 〉: when airborne personnel jump out of aircraft window, will have the facility of opening gas filed bead umbrella automatically to guarantee.＜2 〉: it can make the capacitive strike fuse that human body is upwards launched about 3M highly at " back taper " contact (2) interaction energy that landing lands about 3-5 time in second in advance it is driven by cable wire by its weight sensor, air valve (4) is opened, made two safety air cushions in underfooting (12) inflation.Below all be to carry out automatic guidance via obtaining the data programmed after the experiment.

＜3 〉: " magnetic pushes away " mode of employing makes 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 that has slide rail (6) of two legs, feeler lever can contact to earth in advance when landing and upwards slide by hydraulic boosting owing to land, 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 3 meters a kind of double insurance devices of height power-assisted that bounce.

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

Remove above by multiple class difference, the safety protection device that the totally different textural association of principle forms is also enclosed 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 insurance umbrella (11) can also be opened rapidly simultaneously, certainly this umbrella is much smaller 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 is produced when making the high-altitude landing resists resistance (overcoming difficulties) in the moment of landing, and it highly only has 3 meters high when landing after spring again, the brief acceleration that lands has not again 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 reduce greatly, has also won valuable time for personal safety.
