ABSTRACT:
An aerial toy of the glider type includes a planar body of generally C-shape provided with a central section bounded by two lateral sections. A single, continuous, substantially curved leading edge having a center nose encompasses the forwardmost portion of the entire body, between wing tips defined by the two lateral sections. The trailing edge of the central section is formed by a horizontal stabilizer and is located substantially forward of the trailing edges of the two lateral sections such that an enlarged relief area is provided rearwardly of the central section and intermediate the lateral sections. A vastly sustained flight time is achieved with this body construction, which presents a center of gravity that passes substantially through a point that is one-third the distance from the craft nose, along the overall longitudinal axis of the body, including the central and lateral sections. Maintenance of this center of gravity, as well as both transverse and longitudinal reinforcement of the body, is provided by the attachment of one or more rigid overlays to the body, juxtaposed the leading edge. Launching of the glider is accomplished through use of an elastic device, releaseably connected to a hook member on the body.
