Embodiment one: ground fall
The earth implements 1: it is extreme low-altitude airborne that safe chair 20m falls in sky, see Fig. 1 and Fig. 2, suppose that airline carriers of passengers or transport plane are high at 20m, with 300km/h horizontal flight, place's emergency state, want paradrag drop, this speed and height parachute are to have no idea, and actual dropping from the air should be slower than this, high, suppose that landing person does not have launched machine inspiration to go, also by fuselage or empennage, do not wounded, the people of a 70kg disembarks together with falling chair etc. with sky, and initial condition is:
A, vertical direction: initial velocity is 0, does the movement of falling object, about 2 seconds of touchdown time, vertical touchdown ground speed ≈ 19.8m/s.
B, horizontal direction: because inertia, with the 300km/h ≈ 83.3m/s initial velocity of aircraft equidirectional.
C, horizontal direction: since inertia, the push off speed hypothesis 2m/s vertical with aircraft direction.
D, the speed of these three directions is orthogonal while landing, over the ground the about 85.7m/s of oblique impact speed.This is theoretical environment result of calculation, actual because there is air resistance, should be less than this speed.Such state landed many dangerous just much less, we must be converted into safety speed the speed of these three directions.
Landing process: landing personnel open aircraft safety door, horizontal direction pushes off aircraft with 2m/s speed, leave aircraft after 0.5 second, landing personnel's 1.225m have declined, speed=4.9m/s, also had just land for 1.5 seconds, by sky, safe chair ignition key or mechanical ignition switch fall now, in 1 second, as dreamland, in face of the balloon that diameter is about 7.7 meters appears at, the landing personnel and the object that in the centre of sphere, are seated and just now disembarked, the 2nd second complete landing personnel and gas protective cover waft and also do not land in the sky, gas is manufactured box and is dropped to ground, gas shield layer lands after a while, billow on the ground or shake from side to side and just stopped, landing personnel open valve and make the exhaust of upper channel multilayer protection capsule, see Fig. 2 (9), and leave gas shield layer.
See that the speed threat that how to transform these three directions realizes safe falling below, its stressing conditions is as Fig. 4.
Mg: gravity, f1: the resistance making progress, f2: with the resistance of aircraft flight opposite direction, f3: the resistance of horizontal vertical aircraft flight direction;
Horizontal direction:
F2=kvs ≈ 2.937*83.3*3.14*3.85*3.85 ≈ 11392N direction: with aircraft opposite direction.
F3=kvs ≈ 2.937*2*3.14*3.85*3.85 ≈ 274N and aircraft direction horizontal vertical.
In formula, k is constant 2.937, and v is speed, and s is gas shield layer area of conter over the ground.
These two power are all contrary with original sense of motion, first talk about that large speed 83.3m/s, fall safe chair the same day and left aircraft, just be subject to air resistance, make its speed <83.3m/s, the process that through igniting, gas shield layer is changed from small to big again, further having reduced again speed is vn%, finally, friction drag f2 '=ks (vn%) ≈ 11392n%N that gas shield layer produces in air, this resistance and aircraft flight opposite direction, because one of safe chair initial velocity left falls in Fei Ji Give landing personnel and sky, because of this person and day fall safe chair and push gas shield layer left, see Fig. 5, Fig. 6, simultaneously also because this speed makes gas shield layer produce a friction force f2 ' to the right, stop gas shield layer to left movement, this power slows down gas shield layer and landing personnel fast, this process is if on ground or partly on ground, gas shield layer can produce and drags and roll on ground, even if galled capsule one or two, the gas shield layer that how thick 3m is (quite first floor is high), also can make day person of falling well be protected.This is that the large speed energy of horizontal direction is dissolved process.
Horizontal direction also has a less speed to produce a less friction drag, and its safe switching process is same as described above.
Vertical direction: f1-mg=kvs-mg=ma, a is acceleration/accel, s=π R after gas shield layer has manufactured and designed
2for definite value, k are that constant, mg are gravity, constant in landing process, in formula:
I when v<5m/s, a<0, gas shield layer and landing personnel accelerate to decline
Ii when v>5m/s, a>0, gas shield layer and the landing personnel decline of slowing down
Iii when v=5m/s, a=0, gas shield layer and landing personnel uniform descent,
Whole motion process slows down to transitional processes at the uniform velocity for accelerating to, finally can land with uniform movement 5m/s, see from decelerated movement, remaining height is determined: after gas shield layer open, if highly enough, through slowing down, will land in uniform movement mode, touchdown ground speed=5m/s; If insufficient height, will land in decelerated movement mode, speed is not also reduced to 5m/s
Touchdown ground speed >5m/s; If landed in accelerated movement mode, touchdown ground speed <5m/s.Drop high, gas shield layer open early, speed more approaches 5m/s, drop lower, gas shield layer open is overhead also just low, vertical touchdown ground speed can be very not large yet, the gas shield layer buffer capacity described in also having below of slowing down.
Consider below directly from 20m eminence, to jump off, the speed on the thick gas shield layer of 3m that drops on is v, vertical stroke 17m, v
2=2gh=2*9.8*17=333.2 (m/s)
2, personnel are on gas shield layer in v ≈ 18.25m/s landing, make decelerated movement downwards, and acceleration/accel is a, a=333.2/ (2*3) ≈ 55.5m/s
2≈ 5.7g<<13g; the ejection seat 17g of air force; conventionally landing personnel could bear (12-13) g, therefore need not consider that in air, gas shield layer slows down, as long as the buffering of gas shield layer is just enough to guarantee landing personnel's safety! In fact gas shield layer is subject to air resistance, and speed will reduce, and has this two aspects factor foot to protect landing personnel life carefree.The reason of the extreme low-altitude safe falling of gas shield layer vertical direction that Here it is energy.
The gas shield layer that falls safe chair for this day can be less according to actual design, and above-mentioned two sufficient conditions are used, and both accelerated descending speed, guarantees safety, reduces costs again.About 7.7 meters of this gas shield layer diameter, quite with the airborne 70kg aviator of parachute.
It falls safe chair can accomplish extreme low-altitude, quick, accurate, safe falling.
Extremely extreme low-altitude when airborne, such as high 2m is airborne, inadequate 1 second of fall time, gas shield layer is not also opened just to have landed to threaten and mainly from the speed of horizontal direction, how to be dissolved.Can try every possible means to be hauled and made the aerial residence time extend to for 1 second by aircraft by rope or other, igniting is opened gas shield layer and is landed, and the descendant that lands, at gas shield layer core place, is not afraid of shock, is not afraid of and rolls.
Under above-mentioned various power effects, because center of gravity is square on the lower side, some hip are always downward, and sky falls after safe chair lands and on ground, rolls twice, or rolling two is shaken; Even because of each side reason, or have strong wind, spherical gas shield layer rolls with people; no matter fall with which kind of posture, also no matter how to roll while landing, always while landing across (about 3 meters, the very thick gas shield layer of one deck; suitable first floor); before said, gas shield layer adopts multiple-structure (can design according to various different situations), outer atmospheric pressure is very little; while making to land, produce binding force; just as the ball of flat gas, can not clap, roll motionless.Each layer of air pressure: interlayer pressure is maximum, outwards weakens inwards successively, and when this structure makes to land, impact is fully dissolved, dissipates.
The earth implements 2: safe chair falls in sky, and empty 100m is airborne on earth
From the high movement of falling object of 100m to ground 4.52 seconds, actual because there is resistance, longer than this time, see Fig. 1 and Fig. 2.Landing process no longer described in, only talk after disembarking and how to hold and open gas shield layer point of ignition
A, disembark simultaneously, open sky and fall safe chair gas shield layer, start accelerated movement, when speed reaches 5m/s, with this speed, make uniform movement downwards, until ground.
B, disembark (now 9.8m/s) 1 second time, make day to fall safe chair gas shield layer open, the motion that reduces speed now, when speed reaches 5m/s, makes uniform movement downwards with this speed, up to ground.
C, in order to accelerate touchdown ground speed, decline and within 3 seconds, open again gas shield layer, because gas shield layer slows down and the gas shield layer buffering of landing is enough to guarantee safety in air.For guaranteeing igniting in safety recommendation 3 seconds.
The earth implements 3: safe chair falls in sky, and empty 5000m is airborne on earth
5000m free-falling body 31.94 seconds to ground, actual because there is resistance, longer than this time.See Fig. 1 and Fig. 2 and Fig. 3.
A, disembark simultaneously, open and day fall safe chair gas shield layer, owing to there being 5000m high, air pressure is low, and temperature is low, anoxic, and the time of aloft wafing is oversize, does not advocate, and does not also refuse.
B, suggestion disembark several seconds afterwards igniting open the inside one deck or two-layer of gas shield layer; under this state, uniform descent is excessively to suitable height; open again sky and fall the remaining gas shield layer of safe chair; start to do decelerated movement; when speed reaches 5m/s; with the downward uniform movement of this speed, until ground.
C, in order to accelerate touchdown ground speed, while dropping to overhead a few second, first open the inside one deck or two-layer of gas shield layer, more progressively open remaining gas shield layer, carry out and repeatedly slow down, finally realize and fast and safely landing.
It falls personnel and understands outside situation by watch window, sees Fig. 3, or guarantee in safe situation by the operant level wing and normal limb, opens gas shield layer blow off valve jet, selects landing place.
The day after tomorrow person of falling of landing can open air valve and discharges gas or the portion gas that passage multilayer protection capsule in safe chair gas shield layer upper and lower part falls in sky, out after, discharge all gas, folding gas shield layer and tidy up seat, leaves.
Attention: not the huge kinetic energy accumulating in high-altitude descending process, all or most ofly by gas shield layer, cushioned to bear, can increase like this cost and even cause danger, should be a little earlier 1 open gas shield layer, aloft slow down, reduce kinetic energy.
The earth implements 4: sky falls the real-time ignition energy of safe chair and departs from the do not open impasse of umbrella of low latitude by numerous offices and men such as Feng Siguang
We look at several seconds before the wide martyr of Feng Si sacrifices: according to aircraft seat ejection program, rear deck launches prior to front deck, is spaced apart 1.1 seconds.Just, between these 1.1 seconds, the backseat pilot Zhang Deshan jumping out in advance parachutes successfully.And front seat man is when parachute, aircraft altitude has been down to 32 meters, and with the 16 degree angles of depression, and lower than launching safe envelope curve height, after seat fire, parachute does not open bornly, and front seat man Feng Si is extensively brave and noble-minded.
That is to say that the wide martyr of Feng Si highly launches after lift-off at 32 meters; the wide martyr of Feng Si has 32 meters high at least; than the earth, implement 1 high 12m; situation is well a lot; use sky to fall safe chair; no matter adopt the own operation push-button of remote control, sensing or aviator or mechanical ignition switch opens gas shield layer, aviator can land safely.Vertical direction vertex or 0 speed point 5m also could open gas shield layer completely, could save one's life and allow his the slightest harmless! Regrettably parachute but could be protected warrier's life!
Look at the separately protected ability of gas shield layer below.Directly from 32m eminence, jump to the thick gas shield layer of 3m vertical stroke 29m, speed v, v
2=2gh=2*9.8*29=568.4 (m/s)
2, personnel are on gas shield layer in v ≈ 23.84m/s landing, make decelerated movement downwards, and acceleration/accel is a, a=568.4/ (2*3) ≈ 94.73m/s
2≈ 9.7g<13g, the ejection seat 17g of air force, the personnel of conventionally landing can bear (12-13) g, and the buffering of phosgene body protective cover also could guarantee to launch landing personnel's safety! Moreover also have gas shield layer slowed down by air resistance, have this two aspects factor foot to protect landing personnel life carefree.
2004, " origin " number of the U.S. fell in the desert of Utah, USA.Because parachute is not opened, " origin " number recoverable module data storing tank is inflicted heavy losses on, and the solar wind particle that nearly 3 years of the past of depositing inside causing collects is polluted, and all that has been achieved is spoiled.
