<p>An airship equipped with a function for projecting a video image from a video image projecting means, e.g. a projector, onto a video image display means disposed in the airship body, wherein the optical path of the video image being projected from the projector can be secured without being intercepted by an envelope, or the like, quality of the video image is not deteriorated, and a screen can be set tightly to the side face of the airship body. The airship is provided with an air bag independent of the envelope being filled with floatable gas, e.g. helium, and the video image being projected from the video image projecting means is arranged to pass through the air bag before being projected onto the video image display means. The air bag secures the optical path such that the projected video image reaches the video image display means without being intercepted by anything. A transmission plane of high transparency is employed at the part where the video image projected from the video image projecting means is introduced into the air bag, and at least the side face of the airship being fixed with the screen has a tubular shape.</p> |
