PROBLEM TO BE SOLVED: To reduce the weight of an airframe by using a projector to project a video image photographed by a camera fitted to the airframe onto an inner side face of the airframe comparable to a window so as to eliminate cabin windows or decreased number of the cabin windows and to respond to a request of passengers desiring to see the scenery outside the windows. SOLUTION: In a virtual window forming system for an aircraft, a video camera 2 is provided to a cylindrical airframe 1 of an airliner. The video camera 2 is fitted to an outer side face 3 of a shell being the airframe 1 to photograph a video image changing with navigation of the airliner. A projector 5 installed at a ceiling 4 at the inside of the shell is placed nearly to a center of the airframe 1 and has two projection optical systems 6 almost laterally symmetrically. This projector 5 projects the video image photographed by the video camera 2 onto left and right shell walls of the shell. Through this projection, a virtual window 7 is generated on the shell on which no window is provided. The video image projected on the shell wall may not be as real time video image. |
