Wingtip devices are commonly used on aircraft because of good aerodynamical characteristics. However, the flutter characterization and structural weight are changed simultaneously.In order to explore the overall performance of wingtip devices, three kinds of advanced wingtip devices are researched by using the numerical simulation method.
