后缘隔板对充气式机翼翼型气动力影响分析

Aerodynamic Performances Analysis of the Influence of Trailing Edge Splitter on Inflatable Airfoils’

摘要:

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。

Abstract:

Based on the inflatable wing, the flow over the airfoil of inflatable wing with middle trailing edge splitter was nu.merically simulated by the large eddy simulation method. The inflatable airfoil was blunt trailing edge conducted by airfoilE387. Verification was done between the middle splitter results and no splitter results. The variations of the aerodynamiccharacteristics were summarized to provide useful references for inflatable wing design．
