Description
Technical field
The utility model relates to aerostatics design field, is specifically related to a kind of hydrogen energy source dirigible.
Background technology
Dirigible a kind ofly has propelling and the aerostatics of flight control unit, with regard to its structure, generally include be filled with helium hull, be positioned at gondola below hull, play the empennage of stability contorting effect and the propulsion system of power is provided.Dirigible because of its good reliability and safety, and can carry out the feature of spot hover, is widely used in current taking photo by plane, surveys and draws, in the field such as advertisement.
In recent years, along with the enhancing of common people's environmental consciousness and the progress of electronic Push Technology, and the arrival of advection layer altitude research boom, electronic dirigible becomes the focus of current dirigible field of research.
But the development of current electronic dirigible still has many gordian techniquies to be captured, wherein just comprise the energy and the highly technical matters such as maintenance.
With regard to the height Preserving problems of current stratospheric airship, be specially: due in current dirigible structure, its hull is generally enclosed structure, namely, just whole hull is closed after aerification in hull, can not the be real-time gas of hull inside be regulated, and in dirigible advance or resuspension procedure, environment residing for it and time period have nothing in common with each other, when ambient temperature changes, according to PV=nRT (Clapyron Equation), wherein P is gas pressure intensity, V is gas volume, n is the amount of substance of gas, T is system temperature, R is proportionality coefficient, known, when the temperature increases, the volume V of hull will increase, and when the temperature decreases, the volume V of hull will reduce, again according to Archimedes buoyancy computing formula F=ρ gV, when the volume V of hull increases, the buoyancy that dirigible is subject to increases, now, balance on dirigible vertical direction is broken, dirigible is in rising trend, and when the environment temperature decreases, the volume V of hull shrinks, the buoyancy suffered by dirigible reduces, and now, the balance on dirigible vertical direction also can be broken, and dirigible is on a declining curve.Just because of in this, making the height Preserving problems of current dirigible be difficult to solve always.
As Chinese utility model patent " a kind of solar power rotor inflation soft body unmanned airship ", the patent No. is: CN201420669969.3, its dirigible structure, comprise the unmanned airship that the anterior and middle part of ship body is filled with helium, described unmanned airship ship body is the recessed triangle in middle part, ship is provided with solar energy acquisition and memory storage with it, rising rotor, before push away rotor, swing empennage and video acquisition transmission system, utilize solar power to patrol and examine for a long time for unmanned airship and power is provided, hang time is long, and there is rising rotor and swing empennage, can accurate adjustment hovering position, reduce vibrations, be conducive to collecting image clearly.In that patent, when temperature changes, its ship body still can change, although its in the vertical direction is provided with rising rotor, but this rising rotor when dirigible needs lifting power, can only provide Power output, and any help can not be provided to highly keeping.
On the other hand, current electronic dirigible design all adopts helium to make buoyance lift gas, solar film battery or lithium cell and makes the energy, the technical scheme that electrical motor is used as power:
As Chinese utility model patent " solar energy electric dirigible ", the patent No.: CN200820083421.5, it discloses a kind of solar energy electric dirigible, comprise the hull of bladder configurations, solar cell layer is posted at the upper surface of hull, be provided with driving compartment, helium gas filled device and apparatus for storing electrical energy in the middle part of hull, afterbody is provided with propelling unit; Four Intelligent telescopic supporting legs and four balance propelling units are equipped with in hull bottom, are provided with yaw rudder at afterbody propelling unit rear.This utility model posts solar cell layer due to the upper surface at hull, and daytime, night, by storage battery power supply, can reduce the volume and weight that ship carries storage battery by solar cell for supplying power, and one time cruising radius extends.
For another example Chinese invention patent " a kind of dirigible solar-energy photo-voltaic cell heat control method ", the patent No.: CN201410129192.6, it discloses a kind of dirigible solar-energy photo-voltaic cell heat control method, spacing is left between solar-energy photo-voltaic cell and airship envelope, solar-energy photo-voltaic cell is along the axial continuous laying of dirigible, or interrupted circumference of laying forms solar-energy photo-voltaic cell array, is connected between solar-energy photo-voltaic cell with airship envelope by some well-distributed coupling assemblings; This invention, by leaving spacing between airship envelope and solar-energy photo-voltaic cell, to reduce solar-energy photo-voltaic cell temperature, improves electrical efficiency, eliminates the transmission of solar-energy photo-voltaic cell used heat to dirigible buoyance lift gas simultaneously; On the other hand, do not require that solar-energy photo-voltaic cell is flexible, reduce solar-energy photo-voltaic cell manufacture difficulty.
As the dirigible structure described in above-mentioned two patent documents, because dirigible adopts solar power as propulsion source, need on dirigible, arrange large-area solar film battery and corresponding battery pack, and corresponding electrical motor, and just because making current electronic dirigible all there is remarkable shortcoming in this: 1) solar film battery efficiency is low, required laying area is very large, cause energy weight very large, and solar film battery by monomer be one by one spliced mat formation difficulty, rapid wear, reliability is low and safeguard inconvenience after mating formation; 2) lithium cell specific energy is little, and weight is large, and cost is high, and has charging times restriction; 3) motor power (output) density is low, and when tractive power is larger, the weight of required drive device is larger.So in current electronic dirigible, the energy and engine installation have heavier weight, are first reduction of its load-carrying capacity, but also make the manufacturing cost of dirigible expensive, later maintenance difficulty.
So, need badly at present and a kind of namely there is good height hold facility, the energy and engine installation weight can be alleviated again, and power is lasting, the dirigible of convenient later maintenance.
