摘　　要：3 m×2 m结冰风洞是我国“十一五”国家重大科技基础设施,也是国际上尺寸最大的非季节性结冰风洞。自2013年建成以来,已经完成了70余项试验,有力支撑了我国飞机的自主研制和适航取证。本文首先介绍了3 m×2 m结冰风洞的组成和特点,其次重点阐述了2020年至2022年间风洞试验能力和试验技术的若干新进展,通过发展双闭环自适应温度控制技术、多路热气供气防除冰试验技术、冰形在线测量技术、发动机进气精确模拟技术、旋翼结冰与气动载荷同步测试技术等,使风洞的温度场模拟能力、热气防冰试验能力、冰形测量能力、进气模拟能力和直升机旋翼结冰试验能力得到增强,综合试验效率显著提升。最后,针对大型结冰风洞过冷大水滴试验面临的挑战,对下一步试验技术的发展进行了展望。The 3 m × 2 m Icing Wind Tunnel, a key national scientific and technological facility of Chinese "Eleventh Five-Year Plan",is the largest non-seasonal icing wind tunnel in the world. Since its establishment in2013, the facility has completed more than 70 tests, which strongly supports the domestic aircraft’s independent development and airworthiness certification. The composition and characteristics of the 3 m × 2 m icing wind tunnel are first introduced. Secondly, several new progress in improving wind tunnel test capabilities and developing of test technology from 2020 to 2022 are mainly summarized. Through the development of dual closed-loop adaptive temperature control technology, dual-channel hot-air supply anti-icing test technology, ice shape real-time measurement technology, engine intake accurate simulation technology, rotor icing-aerodynamic load synchronization test technology, etc., simulation capabilities, hot gas anti-icing test capability, ice shape measurement capability, air intake simulation capability, and helicopter rotor icing test capability have been enhanced, and the overall test efficiency has been significantly improved. Finally, the challenges of the largescale icing wind tunnel tests and the development of the test technology for large supercooled water drops are prospected.
