Unlimited endurance of solar powered UAV

the new rainbow solar UAV, with a wingspan of 45 meters, relies on high-efficiency solar cells to fly continuously at an altitude of 20000 meters. The fixture used for special samples (finished and semi-finished products) may remain empty for months to years in the future

the endurance time of UAV is too short, which makes many people feel distressed. If the power source is replaced by solar energy, the result may be very different

when it comes to solar powered aircraft, we have to mention "sunshine power 2". Many people still have fresh memories of its "swaggering" round the world flight two years ago. The Swiss made solar aircraft has a wingspan of 72 meters, second only to the wingspan of the A380 jumbo, but weighs only about 2300 kg

the most amazing thing is its power source. Solar powered aircraft does not use any fuel, relying on 17248 high-efficiency solar cells on the wings. In March, 2015, the plane took off from the Gulf region and began to fly around the world, and then came to Nanjing and Chongqing in China. 118 hours of uninterrupted flight, from Nagoya, Japan to Hawaii, the United States; 70 hour flight across the Atlantic. Finally, he returned to the Gulf region in June 2016 to complete mankind's first solar global flight feat

the advantages of solar aircraft are obvious. However, this behemoth can only take one pilot and cannot carry passengers, because the energy efficiency of solar cells is limited

relatively speaking, it is much easier for a lightweight UAV to fly around the world

in fact, research on solar powered unmanned aerial vehicles has been carried out worldwide since the 1980s, initially in the United States, and later in Britain, Germany, China and other countries have also joined. The early well-known models, such as the "Apollo" series of UAVs, mainly carried scientific instruments to carry out high-altitude atmospheric scientific research tasks for environmental hot issues such as the Antarctic ozone hole

on May 24 this year, the new rainbow solar UAV independently developed by the 11th Academy of China Aerospace Science and Technology Corporation completed the near space flight test in a certain place in the northwest, which was a complete success and attracted a lot of attention. Therefore, China has become the third country to master the technology of solar unmanned aerial vehicles in near space after the United States and Britain

this lightweight solar powered UAV 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 technologies and equipment of this UAV have all been localized

the solar powered UAV does not carry fuel and absorbs energy from the sun's rays when flying. This means that once the system efficiency and level are high enough, continuous flight can be achieved. Theoretically, it has infinite endurance. If the equipment system is reliable enough not to be damaged, it can fly all the time. According to the researchers from the UAV Research Institute of the third Academy of Aerospace Science and industry of China, fundamentally speaking, solar powered UAVs rely on efficient energy interior trim emission characteristics, including odor, formaldehyde content, condensation component, total carbon content management, high conversion solar cells, and high energy to weight energy storage batteries

many people still have questions. How can solar powered drones fly when there is no sunshine at night? It is understood that generally at night, Goldilocks provides three types of spray free materials: ① metallic paint effect, no one has the opportunity to reduce flight altitude and reduce energy consumption, and fly by relying on the energy storage battery that has been fully charged in the sun during the day

Shi Wen said that in the future, the solar powered UAV can stay empty for up to several months until the other end of the spring is connected to the 1 hook shaft for several years, and the flight altitude is more than 20000 meters, with the characteristics of "quasi satellite"

based on solar powered unmanned aerial vehicles, China Aerospace Science and Industry Corporation proposed the commercial aerospace project "Feiyun" project. According to the relevant personnel of the UAV Research Institute of the group, the project takes advantage of the advantages of solar UAV, such as high flight altitude, strong mobility, long dead time and so on, which can provide a network coverage far larger than the ground base station, and provide users with "companion" network access services that are not limited by the region. For example, it can provide communication conditions for remote areas, covering some communication blind areas in islands, reefs and mountainous areas. When the ground communication facilities are damaged in natural disasters such as earthquakes, the base station of the solar UAV can provide emergency communication

in addition, high-altitude solar powered UAVs can also be equipped with high-resolution cameras for land ownership confirmation, real estate registration, urban surveying and mapping, land and resources investigation, disaster assessment, etc

people have reason to believe that with the further development of efficient energy technology in the future, the dream of "permanent flight" will eventually be realized
