The UAV market will continue to erupt in the next ten years. According to the 2015 market research report by the US aerospace consulting company Tire Group, the global drone output will be from the current 4 billion U.S. dollars (about 25.45 billion yuan ) To 14 billion U.S. dollars (about 89.9 billion yuan), bringing the total to 93 billion U.S. dollars (about 591.81 billion yuan). The market research report of research company EVTank pointed out that China sold about 20,000 unmanned aerial vehicles in 2014, of which military drones accounted for about 1.4% and civil unmanned aircraft accounted for 98.6%. It is estimated that the annual sales volume of Chinese unmanned aerial vehicles by 2020 Reached 290,000. Civilian UAV visible momentum of development is very strong.
UAV variety on the market now dazzling range of applications is also more and more widely used, but the battery life rarely increased. EVTank's research report pointed out that the current consumer-level UAV life time is generally within an hour, the main lithium-polymer battery as the main driving force. UAV life on the market generally 20 minutes to 30 minutes, charging time more than one hour, limiting the UAV flight time and flight distance. To promote the long-term sound development of the UAV market, it is of crucial importance to solve the problem of battery life. The good news is that recently, new technologies at home and abroad to solve the battery life to find a new program.
Central South University student Jiang Zhiyuan research and development of autonomous life drone
Central South University student Jiang Zhiyuan invention of autonomous life unmanned aerial vehicle received wide attention in 2015, 120 million yuan injection. The autonomous life UAV did not use lithium polymer batteries, but with solar energy life. The aircraft developed by Jiang Zhiyuan real-time monitoring of their own power, when the power down to a certain level will start when "looking for charging pile" mode to obtain charging pile position, and then in the charging pile of solar panels for wireless charging. Jiang Zhiyuan and his team think UAVs are used for more aerial photographs in China, and they want UAVs to be used in areas such as express delivery, circuit inspection, mapping and border patrols. Through this solar charging pile mode, the UAV can not only perform the task of border patrol, but also cheaper.
Boston CyPhy Works invented the UAV that can never land
Boston UAV maker CyPhy Works recently unveiled a Parc drone capable of performing air cruise missions. The Parc UAV is connected by a "microwire" that can transmit data as well as power from an external generator, vehicle, or other device, meaning that the Parc drone can remain in the air without landing. However, the structure of connecting the power supply by "Microfilament" also has obvious drawbacks, that is, the flight range of the UAV is limited.
How to solve the UAV life problem is not limited to the lithium-polymer battery. How to make rational use of a steady stream of energy to provide flight power to the UAV is a new idea.
