摘 要：
滑流扭转是螺旋桨飞机的一种拉力的副作用，这对航模初学者有非常大的影响。因此本研究为了降低航模的入门门槛，主要针对利用一种风洞与翼刀的结合体，制作并验证一种利用蜂窝结构消减航模滑流扭转状况的装置。研究过程包括优选不同螺旋桨、测试不同桨叶数量、不同类蜂窝结构对滑流效应的力学特性的影响。本次研究得出以下结论：在机体上安装一种采用直径为10mm、数量60个重复单元环绕、轻量化的类蜂窝结构。测试结果显示，该装置的螺旋桨拉力为0.92N，对原始螺旋桨拉力有副作用，损失拉力9.17%；侧推力为0.039N，对滑流扭转消除90.7%。该装置能有效改善滑流扭转效应。

Abstract:
Slipstream torsion is a side effect of thrust in propeller-driven aircraft, which poses a significant challenge for beginners in model aircraft flying. To lower the entry barrier for model aircraft operation, this study focuses on designing and verifying a device that mitigates slipstream torsion in model aircraft by using a honeycomb structure—an integration of wind tunnel and wing fence principles. The research process involves optimizing different propellers and testing the mechanical characteristics of slipstream effect under the conditions of various propeller blade numbers and different honeycomb-like structures. The study draws the following conclusion: a lightweight honeycomb-like structure with a diameter of 10 mm and an arrangement of 60 repeating units is installed on the aircraft body. Test results show that the propeller thrust of the device reaches 0.92 N, which causes a side effect on the original propeller thrust with a thrust loss of 9.17%; the side thrust is 0.039 N, achieving a 90.7% elimination rate of slipstream torsion. This device can effectively improve the slipstream torsion effect.
