The Aizhai Bridge, which blends natural wonders with cultural charm, stands tall amidst the towering mountains of western Hunan, spanning both sides of the canyon. Once upon a time, inspecting a bridge built in the midst of clouds relied on human climbing and eye inspection, with a high degree of danger and long time consumption. Not long ago, the bridge was equipped with a drone, the 'airborne doctor'. It can not only inspect the entire bridge in a few hours, but also not miss even 0.1 millimeters of concrete cracks. Under extreme weather conditions such as extreme temperatures, strong winds, rain, snow, and sandstorms, drones can also achieve stable operation and demonstrate strong environmental adaptability. During the 14th Five Year Plan period, the performance of unmanned aerial vehicles in China has continuously broken through, and their application scenarios have continued to expand. Data shows that China has been the world's largest exporter of residential drones for many years, with patent applications in the drone field accounting for over 70% of the global total, making it the largest source of technology. In recent years, the rapid development of technologies such as artificial intelligence (AI), 5G, and new energy has accelerated the iteration of aircraft models. The integration and innovation of drones with industries such as large models and lithium batteries have accelerated the iteration speed of aircraft models, gradually building a product system that meets the needs of different application scenarios, is low-cost, highly reliable, high-performance, and highly safe. The power battery is the 'heart' of the drone, determining whether the drone can fly far. ”Chen Zhongwei, a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, said. In recent years, drone batteries have continuously broken through performance limitations, achieving improvements in endurance, load capacity, and replenishment speed. Taking off, climbing, high-speed cruising, landing... In the airspace of Changhai County, Dalian City, Liaoning Province, a drone equipped with high specific energy and wide temperature range lithium-ion batteries completed a high-quality 3-hour flight test. It is reported that the drone is equipped with a high-energy lithium battery with an energy density of up to 400 watt hours per kilogram, which increases the drone's endurance time by 20% to 40%; The energy density of the battery module reaches 340 watt hours per kilogram, and it can work stably in a wide temperature range of minus 40 degrees Celsius to over 60 degrees Celsius, providing reliable power support for unmanned aerial vehicles in cold regions, emergency rescue and other application scenarios. Not only is the power getting stronger, but the "brain" of drones is also constantly iterating and becoming smarter. Our drones rely on AI to make decisions, and users only need to define a rough range, and the drones can autonomously plan their flight routes. ”Introduction by Gao Fei, Founder and CEO of Micro Intelligent Fly. In recent years, more and more drones have transformed from "passive executors" to "autonomous decision-makers", not only able to develop flight routes, but also achieve precise obstacle avoidance and complete various complex tasks. The perception bottleneck of drones has also been overcome. For example, in order to solve the problem of "visible" but "inaudible" drones, Chinese research teams have developed miniaturized airborne gas sensing modules and equipped drones with "electronic noses". We have successfully developed a high-performance carbon monoxide sensing unit using nanocomposites as' olfactory 'neurons. ”Introduction by Associate Professor Lian Meiling from Civil Aviation University of China. With the help of an "electronic nose", drones can "sniff" real-time changes in the concentration of carbon monoxide in the atmosphere, not only achieving intelligent perception of the atmospheric environment, but also warning the safety of drone batteries. Empowering traditional industries In recent years, with the innovative development of new materials, sensors, batteries, software and other technologies, drones have gradually integrated with various industries, forming an ecological landscape that empowers thousands of industries. Countless traditional industries have undergone a transformation due to the application of drones. In the underground mining goaf where there is no signal and the structure is complex and dangerous, a drone equipped with intelligent algorithms autonomously shuttles through various mines, generating high-precision 3D models in real time and transmitting multiple detection data. The traditional artificial mining area detection method is not only inefficient, but also highly dangerous. The emergence of drones has brought disruptive changes to this work environment. Combined with the logistics industry, drones have become the "delivery guys" flying in the air. According to data from the Shenzhen Postal Administration, the daily average number of express shipments transported by drones in Shenzhen has reached 20000. The daily processing volume of 20000 drone parcels not only reflects the maturity of technology, but also proves the feasibility of the business model, providing replicable successful experience for the development of the national low altitude economy. ”Wang Qiwen, Deputy Director of the Low altitude Economy Professional Committee of the China Development Zone Association, said. At the disaster relief site, the Yilong emergency unmanned aerial vehicle carries reconnaissance and communication payloads, becoming a vanguard of reconnaissance and communication, effectively ensuring rescue efforts in the disaster area. "Later, we will combine 5G+industrial Internet AI、 New technologies such as big data are promoting the efficient application of drones in various fields such as scientific research, surveying, and logistics. ”Li Yidong, the chief designer of the pterosaur series unmanned aerial vehicles, said. During the 14th Five Year Plan period, the scale of China's drone industry continued to grow, and the integration with industries such as culture, tourism, agriculture, and transportation continued to deepen, becoming a "super engine" to help China's low altitude economy soar. According to the "2024-2025 China General Aviation and Low altitude Economy Development Report" released by the China Air Transport Association, as of the end of June 2025, the number of registered unmanned aerial vehicles in China has exceeded 2.726 million, a net increase of 513000 from the previous year.
