达姆施塔特理工大学开发了一种新型的前缘和后缘耦合襟翼被动减载系统,并对其进行了实验和数值研究。这些实验是在奥尔登堡大学的风洞中进行的,在那里,通过活动网格创造了正弦流入条件,例如代表塔楼堵塞效应的条件。数值研究是在斯图加特大学进行的,使用了准二维装置和块结构的CFD求解器。文中对实验装置作了简要介绍,而对数值装置,特别是风洞条件的实现作了较详细的介绍。此外,还讨论了有无自适应弯度概念的翼型的实测载荷和模拟载荷的比较。
A new passive load reduction system, using coupled leading and trailing edge flaps, was developed at TU Darmstadt and investigated experimentally and numerically. The experiments were performed in the wind tunnel of the University of Oldenburg, where sinusoidal inflow conditions, representing for example the tower blockage effect, were created by means of an active grid. The numerical investigations were performed at the University of Stuttgart, using a quasi two-dimensional setup and a block structured CFD solver. In the present paper, a brief description of the experimental setup is given, whereas the numerical setup, in particular the realisation of the wind tunnel conditions, is presented in more detail. Moreover, a comparison between the measured and simulated loads for an airfoil with and without adaptive camber concept is discussed.
