Study Of The Development Of Unmanned Underwater Craft

As a sea power multiplief, Underwater Unmanned Vehicle (U-U-V) can not onlybe used in various important militny aPplications, but is an important tool fOrpeaceful exploitation of the ocean. Therefore UUV has being attracted more attentionin many countries in recent years, and has become an advanced research project fOrthe development of military sea technology in the developed countries.The paPer discusses the development statlls of foreign U'LJV completely andcarefully, pedicularly introducing that of the AInerican W which includes theleading idea of American U'UV development, the aPplication field of AInericannaVy's M the development target and planning of AInerican naVy's un and thedevelopment of relative proects.The paPer discusses comPletely the aPplication of the foreign UUV in fields ofati-torpedo, ami-submarine, underwater corTununication, ocean inspection, crucialtechnology By analyzing such above, the paPer points out aPplication foregroundand developing direction.The chaPter about key teclmologies in the paPer is emphasis. According todeveloping statUs of foreign wt the paPer details the key technologies of long haulpropulsion/energy of UUV \ sensor and signal disposal' underwater conununication.navigation. mission managemenUcontrol. vehicle body design and so on, then getsconclusion' high intensive energy source, such as fuel batteries and silver oxidebatteries, is the key technology of U'UV, high dataintensive conununication transfersunder water. intelligentization management. progranuning and decision-making.control and precisely navigating technique axe indispensabile fOr developing UUV,The design of the vehicle (including the latent design) is crucial to improve thesurvival competence of UUV The design is related to the technology of materialsvibration &noise reduction. fluid. propeller. low-speeding control and so on. And thepaPer expatiates some important related teclmologies.At the end of the paper, it analyses the developing statlls in our country, findsexisting problems, and research them from several aspects of cognition'technology. management and so on. In the sarne time, UUV developing direction ofour cowtry is denoted according to otir nation stams.Material in the paPer arc systemic and accllIate, and are valuable reference fOrunderstanding develOPing status of UU'V anning skill of foreign countries and fordirccting developing of un tring sldll of our counny...
