The opposite resistance of line direction, f3：The resistance in horizontal vertical aircraft flight direction.
Embodiment one：Ground fall
The earth implements 1：The safe chair 20m that lands is extreme low-altitude airborne, sees Fig. 1 and Fig. 2, it is assumed that airline carriers of passengers or transporter exist
20m is high, with 300km/h horizontal flights, locates the state of emergency, paradrag drop, this speed and height parachute are not do
Method, actual drop from the air should be slow, higher than this, it is assumed that and landing person is not gone by engine inspiration, is not also wounded by fuselage or empennage,
One 70kg people and landing chair etc. disembark together, and original state is：
A, vertical direction：Initial velocity is 0, makees the movement of falling object, touchdown time about 2 seconds, vertical touchdown ground speed ≈
19.8m/s。
B, horizontal direction：Because inertia, the 300km/h ≈ 83.3m/s initial velocity with aircraft equidirectional.
C, horizontal direction：Because inertia, the push off speed vertical with aircraft direction assumes 2m/s.
The speed in these three directions is orthogonal when d, landing, over the ground oblique impact speed about 85.7m/s.This is theoretical environment meter
Result is calculated, it is actual because there is air drag, it should smaller than this speed.Such state land have it is more dangerous just much less
, the speed in these three directions must be converted into safe speed by we.
Descent：Landing personnel open aircraft safety door, and horizontal direction pushes off aircraft with 2m/s speed, leaves aircraft
After 0.5 second, landing personnel have declined 1.225m, speed=4.9m/s, just land within also 1.5 seconds, now by landing peace
Full chair ignition key or mechanical ignition switch, in 1 second, as dreamland, the balloon of about 7.7 meters of a diameter appears in face
Before, be seated the landing personnel to disembark just now and object in the centre of sphere, finishes within the 2nd second landing personnel and gas blanket floats in the sky also
Do not land, gas manufacture box drops to ground, and gas blanket lands later, billows or shakes from side to side on the ground and just stops, people of landing
Member's opening valve makes the protection capsule exhaust of upper channel multilayer, sees Fig. 2 (9), and leave gas blanket.
See that the speed for how converting these three directions threatens below and realize safe falling, its stressing conditions such as Fig. 4.
mg：Gravity, f1：Upward resistance, f2：Resistance in opposite direction, f3 with aircraft flight：Horizontal vertical aircraft flight
The resistance in direction；
Horizontal direction：
F2=kvs ≈ 2.937*83.3*3.14*3.85*3.85 ≈ 11392N directions：It is in opposite direction with aircraft.
F3=kvs ≈ 2.937*2*3.14*3.85*3.85 ≈ 274N and aircraft direction horizontal vertical.
K is constant 2.937 in formula, and v is speed, and s is gas blanket projected area over the ground.
The two power are all with the original direction of motion on the contrary, first saying that big speed 83.3m/s, when landing safe chair leaves
Aircraft, just by air drag, make its speed<83.3m/s, then make the process that gas blanket changes from small to big by igniting, again
It is vn% to further reduce speed, finally, gas blanket caused frictional resistance f2 '=ks (vn%) ≈ in atmosphere
11392n%N, this resistance and aircraft flight are in opposite direction, personnel and land safe chair one to the left because Fei Ji Give land
Initial velocity, therefore people and landing safe chair extrude gas blanket to the left, see figure five, figure six, while also because this speed makes
Gas blanket produce a frictional force f2 ' to the right, prevent gas blanket to left movement, this power make gas blanket and
Landing personnel quickly slow down, and this process can produce if in ground or part in ground, gas blanket on ground
Dragging and rolling, even if having galled one or two of capsule, the more thick gas blankets (suitable first floor is high) of 3m, it can also obtain landing person
To good protection.This is horizontally oriented big velocity energy neutralizing process.
Horizontal direction also has a less speed to produce a less frictional resistance, its safe transfer process with it is above-mentioned
It is identical.
Vertical direction：F1-mg=kvs-mg=ma, a are acceleration, the s=π after gas blanket manufactures and designs completion
R2It is that constant, mg are gravity for definite value, k, it is constant in descent, in formula：
I works as v<During 5m/s, a<0, gas blanket and landing personnel accelerate to decline
Ii works as v>During 5m/s, a>0, gas blanket and landing personnel slow down
Iii is as v=5m/s, a=0, gas blanket and landing personnel's uniform descent,
Whole motion process slows down at the uniform velocity transitional processes to accelerate to, and can finally be landed with uniform motion 5m/s,
See since retarded motion, how much remaining height determines：After gas shield layer open, if height is enough, through subtracting
Speed, it will be landed in a manner of uniform motion, touchdown ground speed=5m/s；If insufficient height, will be landed in a manner of retarded motion, speed
5m/s is not reduced to also
Touchdown ground speed>5m/s；If landed in a manner of accelerated motion, touchdown ground speed<5m/s.Air-drop is high, gas shield
Layer open is early, and speed is closer to 5m/s, and air-drop is lower, gas shield layer open is also just low from the ground, and vertical touchdown ground speed is not yet
Can be very big, gas blanket, which slows down, buffer capacity described below.
It is considered below and is directly jumped off from 20m eminences, it is v, vertical stroke 17m, v to fall the speed on 3m thickness gas blankets2
=2gh=2*9.8*17=333.2 (m/s)2, v ≈ 18.25m/s land personnel on gas blanket, downward to make fortune of slowing down
It is dynamic, acceleration a, a=333.2/ (2*3) ≈ 55.5m/s2≈5.7g<<13g, air force ejection seat 17g, generally landing personnel can
To bear (12-13) g, therefore without considering that gas blanket slows down in air, as long as the buffering of gas blanket is just enough to protect
Demonstrate,prove the safety of landing personnel！Actually gas blanket will be reduced by air drag, speed, have this two aspects factor to protect drop enough
It is carefree to fall human life.Here it is the reason for gas blanket vertical direction energy extreme low-altitude safe falling.
The gas blanket of this landing safe chair can be smaller according to actual design, and above-mentioned two sufficient condition is utilized
Come, both accelerate decrease speed, it is ensured that safety, reduce cost again.About 7.7 meters of this gas blanket diameter, quite uses parachute
Drop from the air a 70kg pilot.
Landing safe chair can accomplish extreme low-altitude, quick, accurate, safe falling.
When extremely extreme low-altitude airborne, for example high 2m is dropped from the air, and inadequate 1 second of fall time, gas blanket is also not turned on just
Land and threatened the speed essentially from horizontal direction how to dissolve.It can try every possible means to make by rope or other hauled by aircraft
Aerial increased retention by 1 second, open gas blanket and land again, lands descendant at gas blanket core by igniting,
It is not afraid of shock, is not afraid of rolling.
Under above-mentioned various power effect, due to center of gravity partial below a bit, hip are downward always, landing safe chair land after
Under ground rolling two, or shake two and shake；Even if because of each side reason, or having strong wind, spherical gas blanket rolls with people, no matter with
Which kind of posture falls, and how to be rolled regardless of when landing, when landing always across one layer of very thick gas blanket (about 3 meters, phase
Work as first floor), before said, gas blanket uses sandwich construction (can be designed according to various different situations), outer layer gas
Pressure very little, produces adhesion strength when making to land, just as the ball of flat gas, can not clap, and rolling is motionless.Each layer air pressure：Interlayer pressure
Maximum, outwards weaken inwards successively, impact is fully dissolved when this structure makes to land, and dissipates.
The earth implements 2：Empty 100m's landing safe chair drops from the air on earth
It is actual because there is resistance from the high movement of falling objects of 100m to ground 4.52 seconds, it is longer than this time, see Fig. 1
And Fig. 2.Descent is no longer described, only talks how to hold after disembarking and opens the gas blanket duration of ignition
A, disembark simultaneously, open landing safe chair gas blanket, start to accelerate, when speed reaches 5m/s, with
This speed makees downwards uniform motion, until ground.
When b, disembarking 1 second (now 9.8m/s), make landing safe chair gas shield layer open, reduce speed now motion, works as speed
Degree reaches 5m/s, makees uniform motion downwards with this speed, until ground.
C, in order to accelerate touchdown ground speed, decline 3 seconds and open gas blanket again, slow down in atmosphere because of gas blanket and
The gas blanket that lands buffering is enough to ensure that safety.To ensure that safety recommendation is lighted a fire in 3 seconds.
The earth implements 3：Empty 5000m's landing safe chair drops from the air on earth
5000m freely falling bodies are actual because there is resistance to ground 31.94 seconds, longer than this time.See Fig. 1 and Fig. 2 and
Fig. 3.
A, disembark simultaneously, open landing safe chair gas blanket, due to there is 5000m high, air pressure is low, and temperature is low, anoxic,
The time floatd in the air is oversize, does not advocate, and does not also refuse.
B, suggest that gas blanket most one layer or two layers of the inside is opened in igniting after disembarking several seconds, in this case uniform descent
Excessively to appropriate height, then the landing remaining gas blanket of safe chair is opened, start to make retarded motion, when speed reaches 5m/
S, with the downward uniform motion of this speed, until ground.
C, in order to accelerate touchdown ground speed, drop to from the ground several seconds when, first open gas blanket most one layer of the inside or
Two layers, then remaining gas blanket is progressively opened, carry out and repeatedly slow down, finally realize and fast and safely land.
Landing personnel understand outside situation by watch window, see Fig. 3 by operating horizontal tail and vertical tail, or ensure peace
In the case of complete, gas blanket air bleeding valve jet is opened, selects landing place.
Landing person can open air valve release landing safe chair gas blanket upper and lower part passage multilayer protection capsule after landing
Gas or portion gas, out after, discharge all gas, fold and gas blanket and tidy up seat, leave.
Pay attention to：The huge kinetic energy accumulated during high-altitude descending is not buffered wholly or largely by gas blanket
To undertake, can so increase and cost or even cause danger, should 1 point of opening gas blanket a little earlier, slow down in the air, reduce dynamic
Energy.
The earth implements 4：The landing real-time ignition energy of safe chair departs from low latitudes by the numerous offices and men such as Feng Siguang and not opened the exhausted of umbrella
Border
We look at the wide martyrs of Feng Si sacrifice before several seconds：According to aircraft seat ejection program, rear deck is prior to front deck bullet
Penetrate, at intervals of 1.1 seconds.Just between this 1.1 seconds, the backseat pilot Zhang Deshan jumped out in advance parachutes successfully.And front deck flies
During member's parachute jumping, aircraft altitude is reduced to 32 meters, and carries 16 degree of angles of depression, less than safe envelope curve height is launched, is dropped after seat fire
Fall umbrella and do not open i.e. born, front seat man Feng Si extensively dies a hero's death.
That is the wide martyrs of Feng Si the wide martyrs of Feng Si at least 32 meters of height, compare the earth after 32 meters of height ejection lift-offs
Implement 1 and want high 12m, situation is well a lot, using landing safe chair, no matter is pressed using remote control, sensing or pilot oneself operation
Key or mechanical ignition switch open gas blanket, and pilot can safely land.Vertical direction peak or 0 speed point are just
It is that 5m can also open gas blanket completely, can saves one's life and make his the slightest lossless！Regrettably parachute can not but be protected
Protect the life of warrier！
Look at the separately protected ability of gas blanket below.Directly jump on 3m thickness gas blankets, hang down from 32m eminences
Direct Travel 29m, speed v, v2=2gh=2*9.8*29=568.4 (m/s)2, v ≈ 23.84m/s landing personnel are in gas blanket
On, make retarded motion, acceleration a, a=568.4/ (2*3) ≈ 94.73m/s downwards2≈9.7g<13g, air force's ejection seat
17g, usual landing personnel can bear (12-13) g, and the buffering of light gas blanket is it is also ensured that the peace of ejection landing personnel
Entirely！Moreover also gas blanket is slowed down by air drag, there is this two aspects factor to protect landing human life enough carefree.
2004, " origin " number in the U.S. was fallen in the desert of Utah, USA.Because parachute is not turned on, " rise
