China energy storage network: the new rainbow solar drone does not carry fuel, and it absorbs energy from the sun's rays while flying.
The new rainbow solar-powered drone, which has a wingspan of 45 meters, relies on efficient solar cells to fly continuously at 20,000 meters and will be left vacant for months or years.
A lot of people are upset about the short duration of the drone.Switching the power source to solar power could make a big difference.
When it comes to solar-powered aircraft, they have to mention "solar impulse 2," and many people still remember the global flight of its "go through the market" two years ago.The swiss-made solar-powered plane has a wingspan of 72 meters, second only to the wingspan of the jumbo A380, but weighs only about 2,300 kilograms.
The most amazing thing is its power source.The solar-powered plane does not use any fuel, and relies on the 17,248 efficient solar cells on its wings.In March 2015, the plane took off from the gulf and began flying around the world, and then came to nanjing, China, and chongqing.118 hours non-stop flight from Nagoya, Japan to Hawaii, USA;The 70-hour flight across the Atlantic.Finally, in June 2016, he returned to the bay area to complete the first solar global flight feat.
The advantages of solar aircraft are obvious.The giant, however, can only fly one pilot and can't carry passengers, because solar cells have limited energy efficiency.
It's relatively easy to fly around the world with a light drone.
In fact, solar drone research began in the 1980s, first in the United States, then in Britain, Germany, China and other countries.Early more famous models, such as "sun" series of unmanned aerial vehicle (uav) is mainly carry scientific instruments, in view of the Antarctic ozone hole hot issues such as environment, develop high altitude atmospheric science research task.
On May 24, China aerospace science and technology group co., LTD. 11 yuan rainbow independent research and development of new solar unmanned aerial vehicle (uav), completed in northwest somewhere near space flight test, a complete success, attract much attention.China has become the third country to master the technology of adjacent space solar drones after the United States and Britain.
The lightweight solar drone is also a "big head" with a wingspan of 45 meters.According to shi wen, chief engineer of the new rainbow solar uav, the core key technology and equipment of the uav will be domestically produced.
Solar-powered drones don't carry fuel, and fly with energy from the sun's rays.This means that a sustained flight can be achieved once it has achieved a high enough system efficiency and level.In theory, it has unlimited navigation, and if the system is reliable enough not to be damaged, it can go on and on.China aerospace science and industry research institute of unmanned aerial vehicle (uav), the researchers said, fundamentally speaking, solar uav depends on efficient energy management, high conversion rate of solar battery, high energy weight ratio of energy storage battery.
A lot of people have doubts, there is no sunlight at night, how do solar drones fly?At night, it is understood that no one has the opportunity to reduce the altitude of the flight, reduce energy consumption, and rely on the energy storage battery that is full of electricity in the sun during the day.
According to shi, the future space for solar drones can last for months to years, and the flight altitude is more than 20,000 meters, with the characteristics of a "quasi-satellite".
Based on the solar drone, China aerospace science and technology group has proposed the commercial space program "flying cloud" project.According to the group institute of unmanned aerial vehicle (uav) related personnel, the engineering use of solar energy unmanned aerial vehicle (uav) flight level is high, the maneuverability is strong, the advantages of the empty time is long, can provide greater than the ground base station network coverage, to provide users with not subject to regional restrictions "with type" Internet access services.For example, it can provide communication conditions for remote areas, covering some islands and reefs, and the communication blind areas in mountainous areas.The base station of a solar-powered drone can provide emergency communications when ground communication facilities are damaged in natural disasters such as earthquakes.
In addition, high-flying solar drones can carry high-resolution cameras for land confirmation, real estate registration, urban mapping, land resources investigation, disaster assessment, etc.
There is reason to believe that the dream of a "permanent flight" will eventually come true with the further development of efficient energy technologies.
