| 中文摘要: |
| 新概念旋转机翼飞机的主机翼既能高速旋转作为旋翼，又可锁定作为固定翼，所以只能使用特殊的前后对称翼型。针对主机翼翼型的这一特殊要求，对16%相对厚度，相对弯度分别为0%和3%的两种椭圆翼型的高速气动特性进行了风洞实验研究，试验分别在中国空气动力研究发展中心FL-21风洞和荷兰代尔夫特大学TST-27风洞进行，采用表面测压和尾排型阻测量技术。试验结果的对比分析表明，有弯度椭圆翼型的升力和力矩特性优于无弯度椭圆翼型，而阻力特性和最大升阻比劣于无弯度椭圆翼型。试验结果为旋转机翼飞机主机翼翼型的选取提供了参考。 |

| Aircraft with new concept rotor wing employs a high speed rotor to take off and locks the rotor to act as a fixed wing. This requires the rotor airfoil blade to be elliptic. Experimental investigation on high speed aerodynamics performance of two elliptic airfoils with 16% relative thickness and 0% and 3% relative curvature and with different camber ratio was performed in a two-dimensional testing section of FL-21 wind tunnel at China Aerodynamics Research and Development Center and TST-27 wind tunnel at Delft University Holand, respectively. The primary objects of these tests are to acquire data to validate the optimization results and develop an airfoil aerodynamic database for calculating the aerodynamic performance of this new aircraft. Techniques of measuring surface pressure and drag measurement with trail total pressure row tube were adopted. Experimental results show that the lift and pitching moment performance of cambered elliptic airfoil is better than that of the symmetrical elliptic airfoil, but the drag performance and maximum lift-drag ratio are worse than that of the symmetrical elliptic airfoil. These experimental results are valuable for the selection of main rotor wing type of this new concept aircraft. |
