トビヘビの断面形状がもたらす滑空性能の調査

Flying snake has no limbs or wings, but it can glide by deforming its body into a flat shape and making it undulate. By implementing this gliding behavior in the search robot, I thought that it would be possible to make it glide. In this study, I investigate the effects of the cross-sectional shape of the body and the gliding posture of the snake on the gliding performance by using a three-dimensional model of the snake. The research includes the analysis of lift and drag coefficients using five different rectangular angles of attack and models of the cross-sectional shape of the flying snake. A comparison of the analysis results shows that the angle of attack has the effect of increasing the lift coefficient and lift-drag ratio and decreasing the drag coefficient as the snake deforms its body during gliding.
