撮要

In recent years, eVTOL, as a frontier representative of low-altitude aircraft, has become a research hotspot in the field of aviation. With advantages such as intelligence, low noise, low cost, high safety, and environmental sustainability, it is regarded as the core equipment of future urban air mobility (UAM) systems and is expected to drive the emergence of a trillion-level industrial chain. However, constrained by the complexities of low-altitude environments and the multimodal requirements of vertical takeoff–cruise flight, achieving efficient and low-noise aerodynamic configurations remains a formidable challenge.

The distributed tilting ducted-fan configuration, known for its excellent payload capacity, maximum takeoff weight, and operational economics, is widely considered the most promising technical pathway. Nonetheless, it still faces bottlenecks arising from multi-physics coupling, mainly including: multi-scale flow control and aeroacoustic co-optimization, distributed power regulation under structural-dynamics constraints, and reliability enhancement of tilting mechanisms driven by intelligent control.

To address these challenges, the presenter proposes a collaborative innovation pathway of “bionic configuration – low-noise design – tilting mechanism.” Centered on the development needs of low-altitude intelligent flight systems, the research focuses on two major directions: efficient low-noise aircraft design and intelligent safe flight control. Specific efforts include advanced aerodynamic configuration and multi-objective optimization design, aerodynamic characteristics and integrated design of distributed electric propulsion systems, tilting strategies and multimodal stability control, intelligent lightweight structures and crashworthy airworthiness design, low-noise control technologies, as well as system integration and flight verification.

By integrating bionic aerodynamic layouts with intelligent optimization algorithms, the work aims to break through traditional design boundaries; innovatively develop bionic propulsion units and tilting corridor control algorithms; and build a highly reliable distributed tilting system to achieve safe, efficient, and quiet flight. The team remains committed to aerodynamic layout integration and distributed power regulation as core technologies, striving to develop low-altitude aircraft that meet aviation safety standards and to provide solid technical support for the industrialization of urban air mobility.
