BUOYANCY ADJUSTING DEVICE, UNDERWATER SAILING BODY, AND BUOYANCY ADJUSTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a buoyancy adjusting device mountable on an underwater sailing body, etc. capable of omnidirectionaly gliding, increasing or decreasing buoyancy without changing a gravity center position and a buoyancy center position in a plane or three-dimensionally, separately controlling buoyancy adjustment and gravity center moving, and easily performing a gliding control of the underwater sailing body, the underwater sailing body provided with the buoyancy adjusting device, and a buoyancy adjusting method.;SOLUTION: This buoyancy adjusting device 1 for adjusting buoyancy adjusts buoyancy by moving floating bodies 12 and 13 having buoyancy adjusting parts 12a and 13a exposed to underwater from a watertight division 11 and increasing or decreasing exposed amount of the buoyancy adjusting parts 12a and 13a to underwater outside the watertight division 11. Buoyancy is changed without entailing movement of the gravity center position and buoyancy center position.;COPYRIGHT: (C)2008,JPO&INPIT
