Product Background

The innovation in the field of materials has laid the foundation for this. New types of high-strength and low-density materials are constantly emerging and being widely applied. Carbon fiber composite materials, with their excellent specific strength and specific modulus, have become the ideal choice for frame manufacturing. They not only significantly reduce the weight of the frame itself but also can withstand huge stress and loads, ensuring the safety and stability of the unmanned aircraft when carrying 15kg of cargo during flight. For example, the frame made by multi-layer carbon fiber weaving process can reduce the weight by approximately 30% compared to traditional aluminum alloy frames, while the tensile strength can increase by more than 50%. 
In terms of structural design, advanced technologies such as computer-aided design (CAD), computer-aided engineering (CAE), and finite element analysis (FEA) have enabled engineers to deeply optimize the frame structure. By precisely simulating the complex stresses endured by the unmanned aircraft during flight, more reasonable frame layouts can be designed. The common multi-axis layout has been meticulously improved, making the rotor lift distribution more uniform, effectively enhancing the flight stability of the unmanned aircraft under heavy loads. At the same time, structural reinforcement is carried out on key parts such as the arms and central frame, improving the overall rigidity and torsional resistance of the frame, significantly reducing the impact of flight vibrations on the cargo, and ensuring a smooth and stable transportation process. 
The upgrade of the power system is also crucial. High-power density brushless motors are continuously being improved, paired with intelligent and efficient electronic speed controllers, which can adjust the power output in real time and precisely according to the flight status. Facing different flight environments and load conditions, the motor can respond quickly, ensuring stable flight of the unmanned aircraft. At the same time, battery technology has made significant progress, with the use of high-energy-density lithium polymer batteries, providing a persistent and stable power guarantee for 15kg payload flights, significantly extending the flight range of the unmanned aircraft and enabling it to undertake longer-distance transportation tasks.

The demand for transformation in the logistics and distribution sector: The rapid development of the e-commerce industry has presented unprecedented challenges to logistics and distribution, especially the "last mile" delivery problem that urgently needs to be solved. The 15kg frame of the transportation drone can flexibly navigate through the skyscrapers of the city, skillfully avoiding congested road traffic, and achieve rapid and precise delivery of goods. Its 15kg load capacity precisely meets the transportation needs of numerous small and medium-sized items, such as fresh food, medicines, small electronic products, and document materials, and can efficiently deliver them to consumers. For example, the 15kg drone used by JD Logistics has piloted delivery services in some cities, significantly reducing the delivery time from several hours to less than half an hour, greatly improving logistics efficiency and customer satisfaction. 
The efficient operation requirements for agricultural modernization: In the agricultural production process, pest control operations and sowing operations often consume a lot of manpower and time, and have low efficiency. The 15kg frame transportation drone can carry sufficient pesticides, seeds or fertilizers and conduct large-scale low-altitude operations above the farmland. Compared with manual or traditional agricultural machinery, the drone operates faster, has a wider coverage, and can ensure uniformity and accuracy of the operation, effectively reducing the waste of pesticides and seeds, and significantly increasing the yield and quality of crops. Taking large-scale wheat planting areas as an example, using a 15kg load-bearing drone for pesticide spraying, the daily operation area can reach several hundred acres, which is tens of times more efficient than manual spraying, injecting strong impetus into the development of agricultural modernization. 
The urgent demand for emergency rescue: When facing natural disasters or emergencies such as earthquakes, floods, and fires, roads are usually severely damaged, and traditional transportation methods are difficult to quickly reach the affected areas, resulting in the inability to deliver rescue supplies in time. The 15kg frame transportation drone can respond quickly, carrying key rescue supplies such as food, medicine, drinking water, and first aid equipment, crossing complex terrains and adverse weather conditions, and precisely delivering them to the hands of the affected people. Its flexible flight characteristics enable it to freely navigate through narrow spaces and ruins, securing precious time for the rescue operation and becoming a key force in ensuring the safety of the lives of the affected people. In a certain earthquake rescue operation, the 15kg load-bearing drone successfully delivered urgently needed food and drinking water to the trapped people in the mountainous area, solving an immediate crisis, fully demonstrating its important role in the field of emergency rescue.

The fierce competition among drone manufacturers: As the drone market continues to expand, more and more enterprises are entering the field of drone manufacturing, making the market competition increasingly intense. To stand out in the competition, each manufacturer is increasing their investment in the research and development of 15kg drone racks for transportation, striving to achieve breakthroughs in performance, reliability, and cost control. They continuously optimize the design of the racks, adopt new materials and advanced manufacturing processes to improve product quality; at the same time, through technological innovation, enhance the intelligence level of drones, such as adding autonomous obstacle avoidance, intelligent return to base, and path planning functions, to meet the increasingly diverse needs of customers. This intense competition is driving the 15kg rack transportation drone technology to continuously iterate and upgrade, with product performance becoming increasingly perfect. 
Competition with traditional transportation methods: Transporting 15kg drone racks as an emerging transportation method requires competing for market share with traditional transportation methods such as cars, trains, and airplanes. Although drones currently have certain gaps in load capacity and range compared to traditional transportation methods, in specific scenarios such as short-distance deliveries within cities and transportation of supplies to remote areas, their flexibility and efficiency advantages are fully demonstrated. To further enhance competitiveness, drone manufacturers are committed to increasing the load capacity of 15kg drone racks, extending their range of operation, reducing operating costs, and strengthening cooperation with logistics companies and e-commerce platforms, exploring more feasible application models, and gradually expanding market space, promoting the widespread application of transportation drones in logistics, agriculture, emergency rescue, and other fields.
