ABSTRACT:
A device capable of flight comprising a wing which includes a leading edge member. The leading edge member has an aerodynamically shaped exterior surface and upper and lower aft sections. The wing also includes upper and lower flexible membranes, a first connector for attaching the upper flexible membrane adjacent the forward region thereof to the upper aft section of the leading edge member and second connector for attaching the lower flexible membrane adjacent a forward region thereof to the lower aft section of the leading edge member. The flexible membranes are joined together rearwardly of the leading edge member. At least one of the connectors includes a track. A member carried by one of the flexible membranes is received in the track and cooperates therewith to attach such flexible membrane to the leading edge member. A support or other device is coupled to the wing for supporting a load.
