To implement an underwater transport airplane shuttling between sea floor and sea surface which has saving energy, saving material, saving equipment and necessary performance to keep safety in a severe environment of high hydraulic pressure in the sea, of communication environment in which radio wave is hard to reach, of visibility environment where the sunlight cannot reach, and so on.SOLUTION: The underwater aircraft introduces the speed control using fluid resistance and uses the change of fluid resistance due to an attitude change of the aircraft for the speed change. The attitude change of the aircraft and the change of the fluid resistance are to perform mapping transformation to the center of the gravity position and to the change of external graphic shape of the aircraft respectively.SELECTED DRAWING: Figure 1
【課題】海中での高い水圧、電波が届き難い通信環境、太陽光の届かない視界環境など、厳しい環境の中で、省エネ、省材料かつ省設備で、安全性を保つのに必要な性能を持つ、海底と海面との間を行き来する海中輸送機を実現すること。【解決手段】流体抵抗を利用した速度制御を取り入れた海中輸送機で、速度変更には機体の姿勢変更による流体抵抗の変化を用いるものである。機体の姿勢変更は機体重心位置の変更に、流体抵抗の変化は機体外面図形状の変化に、それぞれ写像変換したものである。【選択図】図1
