尼龙应用开发大会丨沃飞长空：eVTOL航空器材料应用的机遇与挑战

Group 1 - The core concept of the article revolves around the low-altitude economy, which is supported by low-altitude airspace and promotes the integration and development of related fields. eVTOL (electric Vertical Take-off and Landing) is identified as the core product of this economy, offering advantages such as electric propulsion, intelligence, low noise, and low emissions, thus providing new possibilities for urban transportation [2] - eVTOL's electric power system faces inherent disadvantages in payload and range compared to traditional thermal propulsion systems, necessitating extreme structural lightweighting to compensate for these shortcomings. The design and material selection for eVTOL must differ from traditional aviation approaches due to higher requirements for structural stiffness, vibration characteristics, and aerodynamic stability [2] - Sichuan WoFei ChangKong Technology Development Co., Ltd. focuses on low-altitude transportation and is part of Geely Technology Group. The company aims to innovate around eVTOL and has accelerated the engineering research and commercial application of its AE200 series low-altitude manned aircraft, with a mission to make low-altitude travel accessible to everyone [3] - In June 2024, WoFei ChangKong completed flight test verification for a 2.5-ton tilt-rotor eVTOL, leading the nation in key technology breakthroughs and airworthiness certification progress. The company has secured hundreds of aircraft orders through strategic partnerships with various organizations, targeting applications in passenger transport, tourism, and business travel [3] Group 2 - In November 2025, WoFei ChangKong successfully completed a Series C financing round, attracting strategic investment from Hangzhou Shiji Group and securing orders for 300 AE200 aircraft through partnerships with several financial leasing companies [4] - The 2026 Advanced Nylon Industry Innovation and Application Development Conference will be held in Guangzhou on March 19-20, 2026, focusing on the latest advancements in nylon materials and their applications in various fields, including low-altitude economy [6][10] - The global nylon market is expected to exceed $47 billion, with nylon materials continuously evolving and finding applications in new sectors such as electric vehicles, electronics, low-altitude economy, and humanoid robots. The industry faces challenges and opportunities amid structural adjustments driven by energy system restructuring and market expansion [15]
