Description
Technical field
The present invention relates to a kind of low energy consumption and can become quiet jacking system by speed control soon, it is that one can be applied on the aerostatics such as free balloon, dirigible, flapping-wing aircraft, aerodone, miniplane or low-speed operations device widely, can in space to the deck-level use of vertical space on a large scale, make aerostatics or aircraft at general traffic, recreation toy, go sightseeing, advertising, communication investigation, earth observation, alarm emergency etc. civilian in play a role, this device belongs to aerostatics and vehicle technology field.
Background technology
The mankind have the ideal of free flight aloft very early, the shadow of airflight is had in legend to historical facts, as the all-wing aircraft etc. of the master craftsman of the Spring and Autumn period hovering kite of China, hot balloon, ancient Greek's Icarus, but all do not have tangible proof, the gravity of the earth is still limited in ground firmly people.Until 1783 modern ages, Luo Zeer and the Da Landesi marquis of France had done mankind's free flight first in taking Meng Geerfei fire balloon, and Frenchman Henry Ji Faer in 1852 has done that the mankind are dynamic for the first time mannedly handles flight.Within 1884, Frenchman's row nail (unit of length) captain has successfully taken a flight test by " France " number omnidirectional's manipulation type dirigible of direct motor drive.The Lai Te brother of the U.S. in 1903 takes the lead in producing the aircraft that can fly US-built, and world's airmanship develop rapidly since then, various flying product emerges in an endless stream.Aircraft can be divided into three major types by lift-off principle, by air the lift-off of quiet buoyancy as balloon, dirigible; By the flapping-wing aircraft, aerodone, cyclogyro, aircraft, helicopter etc. that produce aerodynamic force lift-off flight of doing relative motion to air; By the rocket, space shuttle etc. of reverse high speed jet lift-off flight.Mostly build is huge so slower development for the aircraft gone up to the air by the quiet buoyancy of air, rear two class aircraft become the main flow of current aircraft, but this two classes aircraft adopts mostly, and high-speed cruising, operating instruction are loaded down with trivial details, the restriction of spatial domain, place is many, and cost is high, safeguard and use cost high, make it be not suitable for general public routine use.Therefore economically consider the most applicable civilian should be the lighter-than-air flight device as the type such as balloon, dirigible of quiet buoyancy lift-off by air.
Lighter-than-air flight device provides main lift with the air bag being filled with the proportion gas less than air of a bulky, has power control, steerable aviation aircraft.Lighter-than-air flight device has its outstanding advantage relative to other aircraft as fixed wing aircraft, cyclogyro etc., and as vertical takeoff and landing, airborne period is long; can hover for a long time or slowly advance; and energy resource consumption is few, noise is little, pollutes little; good economy performance; according to calculating, transport the expense of one ton of goods with lighter-than-air flight device, fewer than aircraft 68%; fewer than helicopter 94%, half fewer than train.And having widely used helium filling along with aircraft, safety also improves greatly.Energy-efficient performance is better, and economic and practical and for environment destruction is also less.
Existing lighter-than-air flight device makes it there is a lot of shortcoming because of problem such as lifting mechanism, structure design and Practical Condition etc., and current floating lifting technology divides three classes, one be fire balloon adopt be filled with hot air, the air in continuous heating air bag rises, and declines after cooling; Two is that the amount being filled with or discharging light gas with accumulator unit in air bag realizes rising and decline or makes the minimizing of air in the second air bag and increase with vented drum wind apparatus to the second air bags or air inlet thus realize lifting; Three is take-off weights that the main gasbag that is full of light gas significantly reduces aircraft, balloonet is increased in main gasbag, to be vented by balloonet or air inlet keeps the internal gas pressure of main gasbag and provides a small amount of lifting force, wing is had outside main gasbag, producing larger lift to aircraft when certain speed advances, is the major impetus of aircraft lifting.Front two classes need to carry fuel or storage exhaust gear, operation slowly and have certain prestige danger, lift-off height and the hang time restricted, current major part is used in extreme sport or show activity.Three types of technology is widespread use in lighter-than-air flight device at present, but the vented drum wind apparatus needing configuration high density rigid material (iron and steel, alloy etc.) to make and more fuel, increase invalid load-carrying, cause lighter-than-air flight device bulky, make it harsh to the requirement of take off, land place and use weather, ascending and descending process method consumed energy is large, speed slow, and handling is poor; Field-of-view angle is not enough, lack flight support ability.Also part lighter-than-air flight up-to-date technology is had to adopt gas, hydraulic pressure or physical construction to force to make the increase of whole air bag distortion realize lift-off to control special entity in recent years, but all do not depart from the categories such as mechanical moving structure, vented drum wind apparatus or the helium storage device that high density rigid material (iron and steel, alloy etc.) makes, cannot solve and conduct oneself with dignity excessive and cause lighter-than-air flight device to need this defect of huge volume, thus cause lighter-than-air flight device technology to be detained not always.
Summary of the invention
The object of the invention is to the deficiency for existing floating lifting technology, there is provided a kind of novel low energy consumption can become quiet jacking system by speed control soon, structure is simple, small volume, control easy, can can fast and the static lift that changes of controollable when low energy consumption to installing the lighter-than-air flight device after this device or low-speed operations device, static lift can directly rise after exceeding aircraft deadweight, static lift can decline lower than after aircraft deadweight, without the need to other jacking system, and lifting and athletic posture are stablized, and effectively can control rising or falling speed and resident height.
Low energy consumption of the present invention can become quiet jacking system according to flexible sides column metaboly and the design of air bag pressure reduction rebound phenomenon by speed control soon.Flexible sides column metaboly and column side are flexible foldable when bending, upper bottom surface near after, if there is ambient pressure to oppress, side be forced to internally to bend shrink folding after, this column volume will reduce, the stressed separation of upper bottom surface, and this column volume will increase.When air bag pressure reduction rebound phenomenon and air bag internal gas pressure are less than ambient pressure, can shrink until inner and outer air pressure is equal under the effect of ambient pressure.
Low energy consumption of the present invention can speed control becomes quiet jacking system is soon according to above-mentioned phenomenon, the air bag protection deformation device of suitable movable column structure is installed additional in the airtight air bag made with the Polymer laminated film that can arbitrarily fold, air bag protection deformation device is that several lightweight bearing ring equal with air bag cross section is formed by connecting by lightweight toughness network, certain distance is possessed between lightweight bearing ring, upper and lower bearing ring is respectively drawn a toughness rope and is passed balloon surface, with upper traction rope, whole device is suspended on lightweight structural frames, lightweight toughness network connects uniformly and is distributed on multiple lightweight bearing ring and forms cylindrical frame.The air of finding time in air bag; because air bag is that the Polymer laminated film that can arbitrarily fold is made; so whole air bag can shrink; in air bag protection deformation device, lightweight toughness network also can shrink thereupon; but because lightweight bearing ring is incompressible, several lightweight bearing ring will overlap together the shorter column of formation.Air bag is filled with on a small quantity (maximum volume

2) the buoyancy Working medium gas (helium or hydrogen) of normal temperature and pressure seal afterwards; charge calculates gained according to balloon size, air bag face and variable-lift air bag protection deformation device 3 pressure that can bear and loading demands, and variable-lift air bag 2 now volume is V
quiet≈ V

Low energy consumption can become quiet jacking system drawing process by speed control soon, applying external force to the pulling force rope draw off gear 4 be arranged on bottom light rigidity structural framing 1 makes it tighten up pulling force rope 41, transmission external force to variable-lift air bag is protected the lower connecting strand 35 of deformation device 3 to draw the most next lightweight pressure-bearing annulus 32 and is moved, light rigidity structural framing 1 top is connected and fixed on owing to going up most a lightweight pressure-bearing annulus 32, so the spacing of all lightweight bearing rings 32 can increase gradually until maximum, lightweight toughness network 33 between lightweight bearing ring 32 also slowly stretches to tensioned state by contraction state, now variable-lift air bag 2 volume increases, internal gas pressure reduces, extraneous bar pressure compressing variable-lift balloon surface makes it bounce back, but lightweight bearing ring 32 is expanded because being subject to force-extension simultaneously with the lightweight toughness network 33 be connected, bear the compressing of external atmospheric pressure to balloon surface, protection variable-lift air bag 2 does not bounce back and volume constantly increases.Holding external pressure protection increase degree by initial design variable-lift air bag 2 volume is 2-10 times; in it, pressure is corresponding is reduced to 0.5-0.1 doubly; the buoyancy Working medium gas (helium or hydrogen) be filled with due to initial condition is normal temperature and pressure; when not considering temperature traverse; inside and outside differential pressure is 0.5-0.9 barometric pressure; the variable-lift air bag protection deformation device 3 of the lightweight bearing ring 32 that this pressure reduction is made with current material, lightweight toughness network 33 composition can bear easily, thus the buoyancy controllable that whole device is subject to increases.
Low energy consumption can become quiet jacking system contraction process by speed control soon, pulling force rope draw off gear 4 progressively unclamps pulling force rope, variable-lift air bag protection deformation device 3 is not because no longer producing supporting function to the surface of variable-lift air bag 2 by external force, now in variable-lift air bag 2, pressure is less than external atmospheric pressure, so external atmospheric pressure is oppressed balloon surface, because air bag face can arbitrarily fold, the smaller volume so variable-lift air bag 2 will constantly bounce back, until pressure is equal with external atmospheric pressure in variable-lift air bag 2, now variable-lift air bag 2 volume retraction is initial condition V
quiet≈ V
0, thus the buoyancy controllable that whole device is subject to reduces.
