Patent ID: RE43976

Claim:
In an aircraft simulator mirror cell having a base support structure mounted to a movable platform, the base support structure being in generally the shape of a portion of a sphere of a predetermined radius and having a predetermined circumferential extent defined by original edges of the support structure configured to support a vacuum-shaped reflective film, the improvement comprising: a pair of extension wing structures having substantially the same spherical radius as the base support structure and a substantially circumferential extent, each of the pair of wing structures being placed in the effective field of view of a user of the aircraft simulator and attached to one of the original edges of the base support structure and substantially sealed thereto, the extension wing structures, when attached, extending the effective circumferential extent of the base support structure by a substantial amount, thereby increasing an effective field of view of an observer of a vacuum-shaped reflective film; each of the pair of extension wing structures having outer edges for supporting a the vacuum-shaped reflective film and a reflective film supported on the outer edges of the extension wing structures, the reflective film being vacuumed-shaped into a portion of a generally spherical shape.
