The gliding abilities of Chrysopelea paradisi is considered the best among flying snakes. During flight, Chrysopelea paradisi assume a cross-section that is favorable for gliding. Unconventional Micro-Air-Vehicle research may benefit from a study of related cross-sections at these low Reynolds numbers (3000-15000). A total of thirty-one cross- sections created by modifying the biological cross section taken at the mid body of Chrysopelea paradisi during glide are evaluated for their aerodynamic characteristics for Reynolds number 3000 and 15000 at angles of attack ranging from −10+ to 60+ in steps of 5+. These observations would hopefully spur further research and interest in airfoils suitable for unconventional Micro Aerial Vehicles.
