摘要

8 m × 6 m低速风洞悬臂支撑机构是风洞主力支撑装置，其对试验模型的气动干扰可分为近场干扰和远场干扰（主要为悬臂干扰）两部分，采用两步法进行的支撑干扰试验一般仅获取近场干扰量，而获取远场干扰量则较为复杂，普遍对其进行了忽略。本文在8 m × 6 m低速风洞采用流场测量和典型模型测力试验方法对悬臂支撑机构远场（悬臂）干扰进行了研究，获得了较为可靠的悬臂干扰特性，并建立了基本修正方法，可为后续8 m × 6 m低速风洞悬臂支撑机构远场干扰通用修正方法的建立和验证提供数据支撑。

Abstract

The cantilever support device is one of the most commonly used support devices in the 8 m × 6 m low-speed wind tunnel. However

it inevitably exerts aerodynamic interference on the test model

which can be divided into near-field and far-field interferences. Correction of the aerodynamic interference is indispensable for obtaining reliable aerodynamic performance of testing models. The two-step method is commonly used in conventional support interference tests

where only the near-field interference is usually obtained

but the far-field interference is difficult to acquire. In this paper

the aerodynamic interference of the cantilever support device is studied by flow field and force measurement of typical models in the 8 m × 6 m low speed wind tunnel (FL-13) of China Aerodynamic Research and Development Center. Based on analyses of the interference characteristics of the cantilever support device

we propose an effective method for correcting the support interference. These results provide valuable support for developing and verifying the far-field interference correction methods in the 8 m × 6 m low speed wind tunnel.
