Core Viewpoint - The establishment of China's first composite wind tunnel for low-altitude flying vehicles at the Guangdong Academy of Aerospace Technology marks a significant advancement in the low-altitude economy, providing essential testing infrastructure for the development and validation of flying cars and drones [10][11][12]. Summary by Sections Wind Tunnel Overview - The wind tunnel is 47 meters long and consists of three main sections: an entrance section (12m high, 14m wide), a closed test section (3.5m high, 4.5m wide, 10m deep), and an outer wind wall (6m high, 8m wide) made up of 48 wind machines [12][13]. - The wind tunnel can simulate wind speeds ranging from 5 m/s to 50 m/s, equivalent to a maximum of 15 on the Beaufort scale, and the wind wall can reach speeds of 17 m/s, suitable for testing against 7-level winds [12][13]. Importance of Wind Tunnel in Low-Altitude Economy - Wind tunnels are critical for the design validation, aerodynamic layout optimization, and aerodynamic parameter measurement of flying vehicles, with the saying "one generation of wind tunnels, one generation of flying vehicles" highlighting their importance [12][13]. - The new wind tunnel addresses the limitations of existing facilities, which are often unsuitable for medium and large low-altitude flying vehicles, thus lowering the barriers for companies to conduct necessary tests [13][14]. Technological Advantages - The wind tunnel integrates the advantages of aviation-grade wind tunnels and industrial-grade wind walls, allowing for diverse testing scenarios including force measurement, flow field visualization, and dynamic disturbance [16]. - It enhances adaptability and scalability for low-altitude flying vehicle testing, capable of simulating complex wind environments and providing comprehensive aerodynamic performance evaluations [16][19]. Collaboration and Future Development - The Guangdong Academy has established partnerships with multiple enterprises and research institutions to facilitate the use of the wind tunnel for various testing needs [13][19]. - Future plans include developing modules for typhoon-level winds and urban turbulence testing, as well as creating a data-sharing platform for low-altitude flying vehicle testing [19]. Regional Economic Impact - The wind tunnel is strategically located in the Guangdong-Hong Kong-Macao Greater Bay Area, providing an ideal testing ground for low-altitude economic development and fostering collaboration among local research institutions and manufacturing enterprises [14][15].
