摘　　要：翼型升、阻特性实验是空气动力学课程的一项重要实验项目。文章详细阐述了低速翼型升阻特性实验台的设计过程,分析了自制翼型的风洞实验结果。结果表明：实验台工作可靠,实验数据重复性好。该实验台采用了腹撑系统迎角机构、机械式天平及数字测力仪等构件,具有实验成本低、形象直观等特点。Airfoil lift-drag force characteristic experiment plays an important role in aerodynamics. The design process of the test-bed of the low speed airfoil lift-drag force characteristic was introduced, and the experimental results of the airfoil were analyzed. The results showed that this test-bed had high working reliability, and experimental data had good repeatability. The angle of attack organization of free support frontways system, mechanic balance, and digital dynamometer etc are used, so the test-bed has the characteristics of low cost and visualization.
