摘要

本文介绍了一项风洞试验活动的结果,该活动旨在研究装有两个安装在吊杆上的螺旋桨的机翼部分的气动性能和流动物理。所研究的配置意在代表巡航飞行状态下的全尺寸 eVTOL 飞机。由于使用了全尺寸 eVTOL 飞机的部件,因此该装置在最近的文献中是一个相当先进的实验。试验过程中使用了压力测量和红外热成像技术,分别用于评估螺旋桨对机翼的局部影响,以及在不同推力条件下有螺旋桨和没有螺旋桨影响的机翼表面层流数量的定量评估。

Wind tunnel test of full-scale wing-propeller system of a eVTOL aircraft
The present paper describes the results of an experimental wind tunnel test campaign aimed at investigating the aerodynamic performance and flow physics related to a wing section equipped with two propellers mounted on a boom. The configuration investigated is meant to be representative of a full-scale eVTOL aircraft in cruise flight condition. The use of full-scale components of an eVTOL aircraft made this setup a quite advanced experiment in the recent literature. Pressure measurements and an infrared thermography technique were used during the test campaign, respectively, to evaluate localised effects induced by the propeller blowing on the wing and to provide a quantitative evaluation of the amount of laminar flow on the wing surface with and without the influence of the propeller at different thrust conditions.
