eVTOL Aircraft

Zero carbon flight, extremely quiet departure - eVTOL+radiation cooling coating, ushering in a golden age of low altitude economy

eVTOL（electric Vertical Take-off and Landing） Electric vertical takeoff and landing aircraft is an aircraft that is electrified and can take off and land vertically without the need for a runway. Electric vertical takeoff and landing aircraft have the characteristics of vertical takeoff and landing, low noise, low cost, and green energy. Compared with helicopters, eVTOL not only covers some of the advantages of helicopters, but also has the advantages of low noise, greener environmental protection, easy maintenance, more flexible takeoff and landing methods, intelligent digital technology application, low security requirements, more affordable, and low manufacturing and usage costs. It is believed that in the future, eVTOL can replace most of the uses of helicopters, including air travel, urban terminal logistics transportation, aviation medical rescue and other application scenarios, and can also derive new application scenarios such as urban air traffic (UAM) and air taxis. Solving traffic congestion in big cities, easing resource constraints, and promoting the transformation of the aviation industry towards low noise and zero emissions have opened up new ideas and have the potential to become the preferred tool for low altitude economy.

With the increasing number of low altitude flight activities, the driving effect of low altitude infrastructure investment is gradually emerging. In the next few years, China's low altitude economy will continue to maintain a rapid growth trend. It is expected that by 2026, the scale of low altitude economy is expected to exceed one trillion yuan, reaching 1064.46 billion yuan. Among them, the manufacturing of low altitude aircraft and low altitude operational services contribute the most to the scale of low altitude economy, accounting for nearly 55%; The contribution brought by economic activities such as supply chain, production services, consumption, and transportation is close to 40%.

With the continuous advancement of aviation technology, higher requirements have been put forward for the heat dissipation performance of thermal control materials used in spacecraft, namely high temperature resistance, good thermal conductivity and radiation performance. High thermal conductivity carbon/carbon (HTC-C/C) composite materials not only have low density and high temperature resistance, but also have strong thermal conductivity, making them an ideal thermal control material for future high-power spacecraft. At present, HTC-C/C composite materials often have high density, low porosity, and relatively complete graphite layer structure, resulting in low surface infrared emissivity, which affects their radiation heat dissipation effect. In order to fully utilize the thermal control ability of HTC-C/C composite materials, it is urgent to apply a high infrared emissivity heat dissipation coating on their surface.

Inspired by the unique hair structure of the Saraha silver ant, Chuangleng Technology has independently developed multi-component and multi-scale nano particle materials through deep integration of material science, optics, and heat transfer principles, achieving efficient solar reflection and mid infrared radiation through atmospheric windows. The solar reflectivity and mid infrared radiation rate are both as high as 95%, effectively suppressing heat absorption and promoting heat release, achieving zero energy cooling without the need for external power sources and refrigerants. Breaking through the technical bottleneck of traditional thermal insulation coatings that are difficult to achieve a reflectivity of over 90%.
