The demand for lightweight UAVs has continually updated their body materials. Following the lightweight metal materials such as aluminum alloys and titanium alloys, carbon fiber composite materials have become the main force of UAVs. It can be said that carbon fiber composite materials The core UAV structure design and manufacturing technology has become a key technology for UAV development.
Police carbon fiber drone
The new police equipment drone uses a carbon fiber shell, which has the advantages of rapid takeoff and landing, flexible use, low risk of casualties, and low cost. It can collect data on site and quickly transmit it to the command center to track the development of the incident for the commander to carry out Judgment and decision. This type of UAV can also carry out on-site surveys from a wide range of angles, which is unmatched by general monitoring equipment, especially for real-time mastering of special situations such as emergencies.
What are the advantages of using a carbon fiber composite shell for police drones? First, the maneuverability of the drone must be very strong, and the carbon fiber shell can effectively reduce the self-weight of the drone; second, the police drone must adapt to special terrain, disaster weather and other special environments, for example, it is very suitable for gas leakage and other harmful to the human body Under the environment, the carbon fiber material has small creep and strong corrosion resistance, which helps to extend the service life of the body. Police drones are a remedy for the traditional limitations and shortcomings of public security policing activities, and are very effective for improving the efficiency of policing and reducing the casualty rate of police officers under harsh conditions. From 500 in 2015 to more than 7,000 in 2018, the application of police drones is growing geometrically.
Agricultural plant protection / spraying pesticide type carbon fiber drone
Pesticide-sprayed carbon fiber drones can ensure better uniformity of spraying of chemical liquids during operation, and their droplet penetration force is higher than that of locomotive spraying. For example, carbon fiber unmanned plant protection machine is used to spray defoliant on cotton The average defoliation rate can reach more than 90%, and the plant protection machine will not cause damage to cotton vegetation like a locomotive.
The body shell made of carbon fiber composite material can help the unmanned plant protection machine to achieve large capacity and longer endurance with extremely light weight, and improve the efficiency of plant protection operations to a new height. Take a carbon fiber plant protection machine with a capacity of 16L as an example. The plant protection machine has 8 nozzles, the spray range can reach 7 meters, the fastest one minute flow rate can spray 4.8L, in actual operation, it can complete 150 acres in one hour .
The data shows that the current number of UAVs in China exceeds 30,000, and the operating area in 2018 is about 267 million mu. The overall use of pesticides can be reduced by more than 20%, water consumption can be saved by more than 90%, and the utilization rate of pesticides can be increased by more than 30% .
Carbon fiber drone for surveying and mapping
With the development of UAV and digital camera technology, the digital aerial photography technology based on the UAV platform makes the UAV for surveying and mapping in basic surveying and mapping, land resource survey monitoring, land use dynamic monitoring, digital city construction and emergency disaster relief Acquisition and other aspects have a broader application prospect.
In the UAV for surveying and mapping, carbon fiber composite materials can also play a prominent role with the advantages of light weight and high strength. If in the surveying and mapping task, the road conditions are poor and the vehicle is difficult to pass through, the surveying and mapping personnel must take the drone on foot, and the weight of the drone must be as light as possible. Moreover, the cost of manufacturing drones in the industry is very expensive, and the equipment used for three-dimensional mapping and other tasks in surveying and mapping drones are expensive. Once the body is damaged, the economic loss caused is great. Reliability is particularly important. Although the equipment for general surveying and mapping is mainly micro-single and SLR cameras, it only requires a load of about 1 kg. However, some UAVs equipped with lidar have relatively high requirements on the load. For example, LIDAR, IMU, and camera add up to about 5 kg. At this time, the extremely light weight carbon fiber composite body can achieve more loads and achieve longer endurance under the same load.
