Abstract
The invention provides an air floating aircraft with a variable configuration, comprising an outer air bag and a configuration changing control device, wherein the outer air bag is filled with a buoyancy working medium; the configuration changing control device is located at the center part of the outer air bag; the configuration changing control device is composed of a coiling stretching arm and a coiling releasing mechanism; the coiling releasing mechanism is used for coiling or releasing the stretching arm to reduce or increase the height of the central part, so as to enlarge or reduce the volume of the outer air bag; when the air floating aircraft lifts off, the configuration changing control device stretches the outer air bag so that the buoyancy is increased to gradually lift the air floating aircraft; when the air floating aircraft descends, the configuration changing control device initiatively folds to reduce the capacity of the outer air bag, so that the buoyancy is reduced to gradually descend the air floating aircraft.
Description
Technical field
The present invention relates to variable structural form lighter-than-air flight device, it is a kind of comprehensive platform that can be applicable near space, stratospheric communication, investigation, earth observation, early warning etc., belongs to lighter-than-air flight device technical field.
Background technology
Lighter-than-air flight device utilizes to be lighter than air (Lighter-Than-Air, LTA) principle, has power control, can handle motor-driven aircraft.On November 21st, 1783, Frenchman has invented fire balloon the earliest, and this is aerostatics the earliest.1852, French engineer Ji Fade lifted 3 horsepowers of steam engines and screw propeller under the balloon of ellipse, has made first blimp.1898, German neat Berlin count first Design and manufacture went out No. LZ-1, rigid airship, and this dirigible uses skeleton to keep the profile of air bag, and adopt piston engine to be used as power, thus airworthiness is good, and carrying capacity is large.Nineteen thirty-seven Zeppelin company of Germany " Hindenburg number " dirigible fly to Hirst overhead, the Rec accident on fire of New Jersey after, dirigible temporarily exits " golden age ".
But develop with fine chemical technology, novel high-strength compound fabric film material, film, curing technology, and control technology progress, new the army and the people's purposes demand, after 1980, novel airship is paid much attention to by developed countries such as America and Europes and as strategy research and development, various countries competitively develop near space dirigible (stratospheric airship) or near space lighter-than-air flight applicator platform.Lighter-than-air flight applicator platform based on conventional blimp principle is one of current main research platform, huge air balloonet (84 ~ 92% outer bag volume) is had in outer air bag, by blowing engine, valve and control pressurer system, by blowing engine to air blast in balloonet or be vented by valve, make increase and the minimizing of air in balloonet, thus realize landing and lift-off, but this ascending and descending process method consumed energy is large, corollary system equipment weight, be that research is difficult to overcome one of bottleneck at present.Zero-pressure in high-altitude zero-pressure balloon or super-pressure balloon lift-off process capsule, without stable form, restive.Based on the blimp " high-altitude sentry, Hi-sentinel " of specific formation, the same balloon of lift-off principle, lift-off process form is unstable, and after reaching barometric height, State Transferring is difficult to control.These lighter-than-air flight devices all adopt propeller produces thrust, in more than 30km high-altitude, rarefaction of air, propeller efficiency is very low, and its efficiency matching point and low latitude inconsistent.
