Crystal gel airfoils with improved tear resistance and gel airfoils with profiles capable of exhibiting time delay recovery from deformation

摘要

A novel aerodynamic toy comprising a camber defined by one or more inner or outer parameter gel profile(s) in the shape of an airfoil made from an elastic, tear resistant, crystal gel with or without one or more outer parameter gel profile(s) having a connective thin gel membrane, said gel membrane having one or more preselected holes therethrough. The airfoils of the invention exhibits excellent flight stability and no turnover.
