ウィングレットを持つ羽ばたき翼機の性能比較に関する研究

抄録

In recent years, the development of aircrafts with good environmental performance is required to address the global warming problem, and the reduction of aerodynamic drag is an important issue in the development of aircrafts. A wingtip vortex suppression device called a winglet is mounted to the tip of airplane wings. Winglets are modeled after the upturned feathers on the wingtips of gliding hawks and eagles. Winglets have been shown to improve the performance of airplanes by 10% or more. The development of the shape of winglets must be considered in combination with other aspects such as the increase in weight and drag due to the addition of winglets. In this study, we developed flapping wing aircrafts with winglets and compared performances in order to find the optimal winglet mounting angle for flight.
