可模拟7级大风！国内首个低空飞行器专用复合型风洞落成

Core Viewpoint - The establishment of the first domestic wind tunnel dedicated to low-altitude aircraft aerodynamic research marks a significant advancement in the Guangdong-Hong Kong-Macao Greater Bay Area's low-altitude economy, filling a critical infrastructure gap for testing and validating low-altitude flight technologies [1][4][10]. Group 1: Wind Tunnel and Testing Capabilities - The newly completed wind tunnel at the Guangdong Aerospace Technology Research Institute is a composite system that integrates traditional aviation wind tunnel technology with drone testing capabilities, specifically designed for low-altitude aircraft [1][4]. - This wind tunnel is the first of its kind in China, featuring a 4.5-meter scale that allows for comprehensive aerodynamic testing of low-altitude vehicles, addressing the transition from laboratory research to real-world validation [1][4]. - The wind tunnel can conduct tests under conditions of sustained winds, gusts, and lateral winds, meeting the requirements for 7-level wind resistance testing [4]. Group 2: Comprehensive Testing Facilities - Alongside the wind tunnel, a comprehensive testing ground for unmanned systems has also been inaugurated, comprising a physical testing area of 33 square kilometers, vertical take-off and landing zones, and a 5G integrated sensing network [7]. - The digital testing area includes a collaborative design platform, supercomputing center, digital twin center, and a management service platform for unmanned systems, enhancing the research and development capabilities for drone manufacturers and research institutions [7]. Group 3: Industry Collaboration and Future Plans - The Guangdong Aerospace Technology Research Institute has signed strategic cooperation agreements with seven organizations, including Shenzhen Customs and various research institutes, to promote the development of the low-altitude economy through shared facilities and technology innovation [10]. - The institute plans to establish a data-sharing platform for wind tunnel test data, encouraging open data practices and technical exchanges to overcome technological challenges in low-altitude aircraft development [10]. - Future collaborations will focus on key technology breakthroughs in low-altitude aircraft, academic exchanges, and the establishment of standardized testing protocols for wind tunnel experiments [10].
