Description
Technical field
The present invention relates to a kind of large-scale aerostatics of metal construction, the aerostatics of a kind of large-scale metal construction made from metal and alloy sheets that swims in near-space especially for a long time.
Background technology
The aerocraft of filling with the gas that is lighter than air is referred to as aerostatics, aerostatics generally is divided into two kinds in balloon and dirigible, balloon is generally by the lighter-than-air gas composition of packing into of the air bag of softness, dirigible is the aerostatics with propelling unit, is divided into three kinds of blimp, rigid airship and blimps by the shell pattern.Modern dirigible generally all is a blimp, keep their profile, can only be to realize by gaseous tension in the air bag, and its chief component is an air bag, has been full of lighter-than-air gas so that lift to be provided in the air bag the inside, and the inside also has auxiliary balloon in addition.The air bag of modern dirigible by terylene, polyester fiber, step and artificial material such as draw to be made into, but actv. prevents the leakage of helium, and has long period of service.But, up to the present, the mankind also do not have a kind of large-scale floating hollow panel that can rest on near-space (1-12 km) for a long time, its reason is to use the material of existing balloon envelope and dirigible air bag, make large-scale floating hollow panel, though weight is light, but can not (rest in the air) for a long time such as going up a century decades, because balloon and dirigible bag material softness, life-span is short, the cost height, damage easily, gas leaks easily, the aerostatics volume is excessive, in case destroy, lose huge, so be not suitable for doing permanent large-scale floating hollow panel, resemble aerial hotel, the application in aerial city is also just imagined, the human also permanent platform of neither one near-space so far, this technology with human ability with manned moon landing and synchronous orbit space station is extremely unbecoming, but growth in the living standard along with people, can rest on air travel, go sightseeing, leisure, really be one illusioned, happy, romantic thing, the hope of this demand is more and more stronger, can stop skyborne for a long time so we need one, crash-resistant, the large-scale aerostatics that is not easy to destroy, but aerostatics is big more, need the gas of usefulness just many more, use helium cost height, because the hydrogen dirigible once exploded in history, cause many people death, mention the blanketing gas of hydrogen as manned aerostatics, people still have a lingering fear, and using metallic material to do the aerostatics main body is a kind of good selection.Though but that metallic material has is firm, period of service is long, numerous advantages such as be not easy to damage, density is big, and it is also big to conduct oneself with dignity, and the helium of filling is many, and the cost height is not born so the aerostatics of making of thick metal sheet also.
Summary of the invention
Short in order to overcome the material that has balloon or dirigible air bag now as the large-scale floating hollow panel life-span, use helium cost height, damage easily, can not forever stop skyborne shortcoming, the invention provides metal case and can use the scheme of hydrogen safely as the aerostatics blanketing gas as the large-scale aerostatics of floating empty main body, realized a kind of long life, survivability is strong, be not easy gas leakage, cheap large-scale aerostatics, be aerial hotel, aerial city, aerial solar power station, the realization of aerial wind power station is paved the way, even use helium, though cost is higher, cost has just reduced naturally but long-term use is on average got off, and uses hydrogen just not have this problem.

The selection of aerostatics main body and annex material:
Aerostatics main body 1: can use aluminum alloy, ferro-alloy, stainless steel and other metal materials, the shell done of the metal sheet of same thickness just is under same load, the volume that the metal needs that density is big is wanted is bigger, which kind of by adjusted volume,, generally can both meet the demands no matter use Metal and Alloy.
Solar cell 6: owing to consider weight, select thin-film solar cells comparatively desirable, now there has been 0.1 kilowatt/kilogram product to sell, just 1 ton of one 100 kilowatts solar-electricity station battery gross weight, can satisfy the demand of the daily electricity consumption of aerostatics fully, solar cell 6 is installed in aerostatics main body 1 surface.
Load 10: determine as required, but can consider to use the material light, that intensity is big that if use as aerial hotel, the room can just need to consider the intensity and the weight of material by ground hotel facilities configuration.
Winch 13, hawser 14, gondola 15, positioning rope 16: winch 13 be used to control gondola 15 about, gondola 15 is used for aerostatics and ground exchange goods and materials, personnel etc. up and down, so hawser 14 requires certain length and intensity, positioning rope 16 is one section rope below the gondola 15, when gondola 15 rocks during near ground indefinitely, draw positioning rope 16 fixing earlier.
Aerogenerator 26: being used for aerial wind-power electricity generation, particularly night does not have under the situation of solar power, and aerogenerator 26 can replenish the part energy, must consider weight during manufacturing.
It is floating empty in order to illustrate that even the present invention has used thicker metal sheet also can realize, suppose that below big shaped metal aerostatics of manufacturing carries out the estimation of omiting at the beginning of to the present invention, as long as the weight of aerostatics main body is less than buoyancy that it produced, aerostatics just can swim in the air for a long time, so the weight and the buoyancy of following estimation aerostatics main body, as for the weight of load and other appurtenances, can regulate by changing aerostatics volume size and outer casing thickness.
Suppose: the aerostatics main body be one long 300 meters, 100 meters of diameters cylindrical, adopt the thick high-strength aluminium alloy plate of 3mm to be welded, wherein be full of hydrogen or helium, aluminum alloy density is calculated by 2750 kilograms per cubic meter, float on the high aerial of 3000 meters of height above sea level, the high aerial density of air that height above sea level is 3000 meters is 0.8 kilograms per cubic meter slightly.
The volume of aerostatics=3.14 * 50 meter * 50 meters * 300 meters=2355000 cubic meters;
Aerostatics is with 906 tons of thickness * 2750 kilograms per cubic meter=(2 * 3.14 * 50 meters * 300 meters+2 * 3.14 * 50 meters * 50 meters) * 0.003 meter * 2750 kilograms per cubic meter of the face area * aluminum alloy of the density=aluminum alloy of the volume * aluminum alloy of the quality=aluminum alloy of aluminum alloy=(94200 sq ms+15700 sq ms) * 0.003 meter * 2750 kilograms per cubic meter=906675 kilogram ≈.
Density of air=2355000 cubic meters * 0.8 kilograms per cubic meter=1884000 of the volume * place height of the buoyancy ≈ aerostatics that aerostatics produces kilogram=1884 tons.
Poor=1884 of buoyancy and aerostatics body weight tons-906 tons=978 tons.
As seen, as long as being no more than 978 tons, the gross weight of load and miscellaneous part just can make a huge aerostatics swim in 3000 meters high aerial for a long time, aerial hotel, aerial city will no longer be illusion, but can realize, perhaps the someone says that this investment is excessive, but can realize the long-term floating skyborne large-scale aerostatics of a long period (more than decades), its economic benefit is very considerable, investment has no relations more greatly, such as there being every day 1000 people (to omit 70 tons of weight, only account for the minimum part of aerostatics buoyancy) tourism in the above, go sightseeing, leisure, by 5000 yuan of/day calculating, one day volume of business is approximately 5,000,000 yuan, and 1 year is 1,800,000,000, estimates about the 1 year cost of just recouping capital outlay.
In order to prove that the aerostatics main body can use thicker metal sheet manufacturing, we give one example and illustrate.
Suppose: the aerostatics main body is long 3000 meters, the cylinder that diameter is 1000 meters, adopt the steel plate of 1 cm thick to be welded, wherein be full of hydrogen or helium, steel plate density is calculated by 7.8 tons/cubic meter, aerostatics swims in 3000 meters high aerial, and 3000 meters aerial density of airs are 0.8 kilograms per cubic meter slightly.
The volume of aerostatics=3.14 * 500 meter * 500 meters * 3000 meters=2355000000 cubic meters;
Aerostatics is with face area * steel plate thickness * 7800 kilograms per cubic meter=(2 * 3.14 * 500 meters * 3000 meters+2 * 3.14 * 500 meters * 500 meters) * 0.01 meter * 7800 kilograms per cubic meter=(9420000 sq ms+1570000 sq ms) * 0.01 meter * 7800 kilograms per cubic meter=857220000 of the density=steel plate of the volume * steel plate of the quality=steel plate of steel plate kilogram=857220 tons=85.722 ten thousand tons.
Density of air=2355000000 cubic meters * 0.8 kilograms per cubic meter=1884000000 of the volume * place height of the buoyancy ≈ aerostatics that aerostatics produces kilogram=1884000 tons=188.4 ten thousand tons.
Poor=188.4 ten thousand of buoyancy and aerostatics body weight tons-85.722 ten thousand tons=102.678 ten thousand tons.
Even as seen one long 3000 meters, 1000 meters of diameters, the large-scale floating empty body that adopts the steel plate of 1 cm thick to be welded floats on the high-altitude of height above sea level 3000, deadweight is outer can also to provide about 1,000,000 tons buoyancy for load and other attendant equipments except bearing.Owing to adopted the steel plate of 1 cm thick, floating empty body case is firm unusually, be not easy to destroy, let alone gas leakage, estimation can stop more than one thousand years aloft, because period of service is long, it is not high to divide the back cost, still has investment value.
