本文扼要介绍香港宝莲寺大佛模型在北京空气动力研究所的3米×3米低速风洞中的试验情况。试验结果表明,全模型气动力中,轴向力系数最大,侧力系数次之;力矩中俯仰力矩系数最大。滚转力矩系数次之。右手气动力以轴向力系数为最大,力矩以俯仰力矩系数为最大。右手最大轴向力约占全模型最大轴向力的6.5%。佛身对右手的气动干扰是严重的。雷诺数对模型气动特性没有明显的影响。
This article briefly introduces the test of the Buddha Statue of the Po Lin Monastery in Hong Kong in a 3m × 3m low speed wind tunnel at the Beijing Institute of Aerodynamics. The experimental results show that in the whole model aerodynamic force, the axial force coefficient is the largest, followed by the lateral force coefficient, and the torque moment coefficient is the largest. Rolling torque coefficient second. The right-hand aerodynamic force is the maximum axial force coefficient, torque to pitch torque coefficient is the maximum. The maximum axial force of the right hand accounts for about 6.5% of the maximum axial force of the model. The aerodynamic interference of the Buddha body to the right hand is serious. The Reynolds number has no obvious effect on the aerodynamic characteristics of the model.
