摘　　要：为真实模拟人工影响天气机载探测设备动态工作环境,提高机载探测设备检测水平,推动国产机载探测设备研发,本文设计一种回流式闭口风洞。风洞主体包括试验段、扩散段、拐角段、动力段、换热段、稳定段、收缩段、预留段等部分。风洞最大外形尺寸为31.33 m×10.18 m×5.436 m(长×宽×高),试验段截面尺寸为1.2 m×1.2 m,稳定风速范围为30~150 m/s。经流场校测,风洞流场品质指标:风速范围、动压稳定性、落差系数、湍流度、气流温度、轴向静压梯度、方向场及动压场等均达到GJB1179A-2012合格要求,能够满足机载设备的检测需求。风洞的气动和结构设计合理,可为今后类似风洞的设计和建造提供参考。With the development of artificial weather modification efforts,the importance of aircraft for cloud seeding becomes increasingly significant.The effectiveness of aircraft for cloud seeding heavily relies on the stability of onboard detection equipment.To effectively simulate the dynamic operational environment of airborne detection equipment used in artificial weather modification and to enhance the detection capabilities of such equipment,this study presents a design for a recirculating closed-circuit wind tunnel.The primary structure comprises several sections:the test section,diffuser section,corner section,power section,heat exchange section,stabilisation section,contraction section,and reserved section.The interior contains built-in components such as corner guide deflectors,cellular devices,damping screens,heat exchangers,etc.The wind tunnel is arranged horizontally,with a centreline length of 28.09 m and a short axis distance of 5.71 m.The maximum dimensions of the wind tunnel are 31.33 m×10.18 m×5.436 m(length×width×height),while the cross-sectional dimensions of the test segment measure 1.2 m×1.2 m with a stable wind speed range from 30 to 150 m/s.The actual sizes of the airborne detection instruments are taken into account in the design of the test section.Based on a contraction ratio of 12.25,the stable section is designed with a square cross-section of 4.2 m×4.2 m.The diameter of the power section is set at 2.4 m.To prevent damage to the fan blade from test pieces or other objects,a protective net is installed in front of the power section.To verify the rationality of the wind tunnel design,the flow field quality of the wind tunnel is tested according to the“Low-Speed and High-Speed Wind Tunnel Flow Field Quality Requirements”(GJB1179A-2012)and the“Wind Tunnel Control System Design and Checking Guidelines”(GJB 5221-2004).Following flow field calibration tests,various quality indicators-including wind speed range,dynamic pressure stability,drop coefficient,turbulence intensity,airflow te
