Description
[technical field]
The present invention relates to a kind of aircraft, and in particular to one kind directly provides driving power using hydrogen as the energy, with proton
Exchange film fuel battery PEMFC hydrogen electric stack is the aircraft of power generator, including manned and unmanned, fixed-wing and rotation
Wing aircraft.The aircraft building block is related to storing electric energy battery, is related to improving the supercapacitor of electric energy storage device performance,
Further relate to the technical fields such as electronic circuit and various sensors, embedded type automatic-control device and embedded software；The present invention uses
Portable changeable type high-pressure hydrogen storing tank provides energy, therefore further relates to the neck of technology involved in high-pressure bottle and its auxiliary component
Domain and high pressure gas energy regenerating decompressor technical field.
[background technique]
The fixed-wing and rotor craft of current mainstream in the world, all provide driving force using fuel engines, either
Unmanned to drive, especially someone drives aircraft, belongs to this seed type.
It is well known that fuel oil aircraft deposits generation for many years, superiority and outstanding advantages from need not say, shortcoming but also very
Obvious: fuel oil, which largely consumes, causes atmospheric environment seriously to pollute, and more has noise jamming, intolerable in many cases,
For example, the tourism operational service that helicopter is gone sightseeing around city overhead is opened in some cities in recent years, enterprise merely makes money,
I am honoured by your visit, and noise disturbs residents, the serious infringement right of numerous residents An Xiang life of calm！
Either with or without taking into account enterprise management efficiency and resident lives in peace the method that harmonious coexistence between right makes the best of both worlds?
In fact, the progress of modern science and technology and advanced manufacturing industry, can solve problems completely, and solution is " electronic
Flight ".With brushless, permanently high-power driving motor, high-power semiconductor switch control device, high-energy-density battery, insertion
The technologies such as formula intelligent control circuit and Intelligent flight control software, which are maked rapid progress, to be substantially in progress and becomes better and approaching perfection day by day, and nowadays all may be used
To realize.
Recent domestic has all developed electric airplane, China can RX1R " Ruixiang " the double light-weight electric of volume production fly
Machine, charging can continue a journey 45-60 minutes for 15 hours, and European Air Passenger group releases full electric power training aircraft ... of E-Fan2.0 etc..But
According to disclosed index: current such aircraft loads ability is weak, and cruise duration is short, wouldn't have scale commercial promise.
Weight bearing power is weak, and cruise duration is short, this is exactly the defect place of current pure electric vehicle aircraft.The reason is that:
Such aircraft all only relies only on battery and provides electric power, fortunately battery industry progress for many years, the electricity substituted plumbic acid of lithium, otherwise according to
Can not always it go up to the sky by heavy lead-acid battery: too heavy！But lithium battery is not also light, even newest " high capacity density "
Ternary battery core, also only 0.3kwh/kg allow the double light-weight electric aircraft heaven of Ruixiang, stronger than early stage lithium electricity not how many, also wants
150kg！To tackle the problem at its root, only look for another way, thoroughly changes the power General layout Plan of this type aircraft.
It is easiest on the earth in the substance obtained, the highest substance of electrochemical energy mass density surely belongs to hydrogen, up to
32.7kwh/kg.Proton Exchange Membrane Fuel Cells PEMFC rapid technological improvement in recent years, various hydrogen electric stack in addition to independent development,
It can be obtained from the market, still more the technical indicator of hydrogen electric stack product is continuously improved, cost declines to a great extent, for based on hydrogen
The marketing of pile application product creates feasible prerequisite.Therefore, by the components such as hydrogen electric stack be used for aircraft be can
Capable strategic choice.
[summary of the invention]
Based on above-mentioned analysis, drip irrigation device provided by the present invention is: [1] is to purely by battery offer driving
The electric airplane of the energy is transformed, and the battery components for energy storage are greatly reduced to mitigate weight, hyperphoric parameter matching
Proton Exchange Membrane Fuel Cells hydrogen electric stack, be equipped with changeable type high-pressure hydrogen storing tank to promote energy storage, constitute completely new electric power and protect
Barrier system replaces original electric power supply system；[2] completely new hydrogen electric stack Electric aircraft based on the above principles is developed.
A kind of hydrogen electric stack Electric aircraft, it is characterized in that: being equipped with what high-pressure hydrogen storing tank was constituted by core component of hydrogen electric stack
Power supply system, electric energy needed for being provided to Electric aircraft.
The hydrogen electric stack power supply system of electric energy needed for aircraft is provided, by Proton Exchange Membrane Fuel Cells hydrogen electric stack, power type
Battery group, power type supercapacitor, embedded intelligence electric power controller, changeable type high-pressure hydrogen storing tank and matched
The decompressor for having high pressure gas mechanical energy recycling generating function and position are between hydrogen electric stack and portable high-pressure hydrogen container
Between, the low pressure seal container of 0.05-0.15MPa is worked in, the low pressure buffer hydrogen container with impact resistance is constituted.
A kind of hydrogen electric stack Electric aircraft, it is characterized in that: the hydrogen electric stack power supply system of electric energy needed for aircraft is provided, by matter
Proton exchange film fuel cell hydrogen electric stack, power type accumulator battery, power type supercapacitor, embedded intelligence electric power controller are high
Pressure hydrogen container and the matched decompressor for having high pressure gas mechanical energy recycling generating function and position are between hydrogen electric stack
Low pressure buffer hydrogen container between high-pressure hydrogen storing tank is constituted.
A kind of hydrogen electric stack Electric aircraft, it is characterized in that: the hydrogen electric stack power supply system of electric energy needed for aircraft is provided, by matter
Proton exchange film fuel cell hydrogen electric stack, power type accumulator battery, power type supercapacitor, embedded intelligence electric power controller, just
Take changeable type high-pressure hydrogen storing tank and the matched decompressor for having high pressure gas energy regenerating generating function and position
Low pressure buffer hydrogen container between hydrogen electric stack and changeable type high-pressure hydrogen storing tank is constituted.
Although hydrogen energy density is up to 32.7kwh/kg, about 3 times of fuel oil energy density, about ternary lithium cell 100
Times！But it is intuitive clearly disadvantageous to be: its volume such as is about at 10,000 times of oil volume of restriking at normal atmospheric pressure！If will
Hydrogen is directly used on aircraft as the energy, just must substantially compress its volume.German Japan's high-pressure hydrogen storing tank standard is
70MPa, the current high-pressure bottle in China is up to 50MPa, about 500 atmospheric pressure.
