Spherical projection-type screen for use in a vehicle simulator

Abstract

A geodesic dome structure is described, i.e., a structure having a mathematically-derived surface. This new dome structure is formed of a single, one-piece layer of synthetic material and provides a one-piece, seamless screen to permit the viewing of a scene in a vehicle simulator in order to achieve a maximum of realism matching substantially real world conditions. One form of the structure for this geodesic dome is described with the single, one-piece layer of synthetic material bonded to a generally dome-shaped geodetic structure in order to provide sufficient strength for a free-standing structure. However, another form of the geodesic dome is described with the synthetic material formed of sufficient thickness to be strong enough to provide a free-standing structure, and the synthetic material may even be reinforced if desired. The method described of achieving this geodesic dome includes erecting a generally dome-shaped geodetic structure and applying a coating of a predetermined thickness of synthetic material to the inner surface of such a structure. Thereafter, this synthetic material is smoothed to provide the seamless screen for viewing a scene from a vehicle simulator. The method described also includes a tool stand erected in order to locate positively a pivot point from which a tool boom is movable in order to achieve the accuracy desired for the inner, smooth, one-piece, seamless screen surface.
