Abstract
The present authors have been investigated a canard type roadable aircraft fixed an inflatable ring wing as for the future vehicle. In this research, two-dimensional inflatable wing was tested using wind tunnel to predict an effect of a deformation of wing on aerodynamics forces. Furthermore, CFD simulation was conducted to predict the detail of flow field around an inflatable wing. It is clarified that the lift and drag of a deformed wing increase than non-deformed wing and an increasing rate of drag by a wing deformation is higher than lift.
