以充气式机翼为背景,研究了安装后缘隔板充气式翼型的气动特性。以翼型E387为基础生成的钝后缘翼型为研究对象,采用大涡模拟方法对安装中部隔板的充气式翼型进行了流场数值计算,并与未安装隔板的情况进行了对比。总结了后缘中部隔板对充气式翼型气动特性影响的变化规律,为充气式机翼设计提供参考。
Based on the inflatable wing, the aerodynamic characteristics of the inflatable airfoil with the trailing edge bulkhead are studied. The blunt trailing edge airfoil generated based on the airfoil E387 is taken as the research object. The numerical simulation of the flow field of the inflatable airfoil with the middle partition is carried out by the method of large eddy simulation and compared with the case without the partition . The variation rules of the aerodynamic characteristics of the inflatable airfoil at the middle of the trailing edge are summarized, which can provide references for the design of the inflatable airfoil.
