摘要
河南队的S8EP项目与北航特种飞行器研究室合作,利用专业的航空理论知识绘制了翼型升力系数随迎角的变化曲线、阻力系数随迎角的变化曲线、升阻比随迎角的变化曲线、俯仰力矩随迎角的变化曲线进行对比,绘制出了机翼表面的压力分布图。根据显示的压力分布图来科学地设计飞机模型结构,并进行了风洞试验得出系列的科学数据。随后安装了微型高度记录仪进行试飞,以科学理论和实践飞行相结合的方式来达到提高性能、扩大优势的目标。
Collaborating with Specialized Aircraft Laboratory of Beijing University of Aeronautics and Astronautics, Project S8EP of Henan Provincial Team applies theoretical knowledge of aviation to draw the curve depicting the change of airfoil lift coefficient against the angle of attack, that of the drag coefficient against the angle of attack, that of lift-drag ratio against angle of attack, and that of pitching moment against angle of attack. After comparing them, a chart of pressure distribution on the surface of the wings was drawn. The structure of the model plane was designed according to this and a series of wind tunnel tests are conducted. Then install the mini-altitude test flight recorder, the flight of scientific combination of theory and practice ways to increase performance, expand the target.
