本文介绍了在蒙雷亚尔ETS主动控制、航空电子和气动伺服弹性应用研究实验室(LARCASE)进行的一种新的变形机翼系统的设计和制造。变形机翼的第一个版本允许其后缘变形，表示为变形后缘(MTE)。为了表征这种变形的技术影响，我们通过在LARCASE的价格-Pai-doussis亚音速风洞中进行测试，将其性能与刚性副翼的性能进行了比较。第一组结果表明，在机翼上用MTE代替副翼是可能的，因为观察到MTE的空气动力性能相对于副翼气动性能有了改善。在相同的升力系数下，阻力系数较小，升阻比较大。
This paper presents the design and manufacturing of a new morphing wing system carried out at the Laboratory of Applied Research in Active Controls, Avionics and AeroServoElasticity (LARCASE) at the ETS in Montréal. This first version of a morphing wing allows the deformation of its trailing edge, denote by Morphing Trailing Edge (MTE). In order to characterize the technical impact of this deformation, we compare its performance with that of a rigid aileron by testing in the LARCASE’s price—Païdoussis subsonic wind tunnel. The first set of results shows that it is possible to replace an aileron by a MTE on a wing, as an improvement was observed for the MTE aerodynamic performances with respect to the aileron aerodynamic performances. The improvement consisted in the fact that the drag coefficient was smaller, and the lift-to-drag ratio was higher for the same lift coefficient.
