The measure and decision of technical risk in the development of naval vessels

The risks in development of navy vessels were explored, The resources of technical risk in the design and development of vessels were mentioned, It was pointed that technical risk dominated the other risk components. Based on the writers＇ understanding and experience from risk analysis and risk ,nanagement to the development of a navy vessel, four measure indexes of technical risk were presented. The decision criteria and the rules corresponding to the indexes were estahlished by the statistic information,

A new method to accurately measure the drift of shipborne floated gyro

Shell-feeding velocity is an important factor affecting naval gun shooting capacity. An agile shell-feeding system was designed to ensure quick implementation of the shell-feeding task. Based on composition of the agile shell-feeding system, hoist technology was studied. Working principles were discussed and the hydraulic pressure system of the hoist was constructed. The hydraulic pressure cylinder and the accumulator were analyzed and calculated. Finally, PRO/E and ADAMS were used to simulate the hoist and its hydraulic system. It was found that this type of virtuaU674.7l prototype provides a good method to actualize a physical prototype.

别样潜艇处处鲜 推向国际市场的法国SMX系列潜艇

法国舰艇建造局(DCN)是法国海军舰艇的“摇篮”,也是国际驰名的舰艇设计商,其研制的“桂树神”级,“阿戈斯塔”级和“鲉鱼”级常规潜艇畅销欧、亚、非及南美洲多个国家的海军。为推动中小国家海军实现发展潜艇部队的愿望及满足部分国家海军濒海、特种作战等需求,进入21世纪后,法国舰艇建造局已经先后推出了面向国际市场的SMX-21型双体潜艇、SMX-22型三体组合潜艇和SMX-25型低成本濒海战潜艇。SMX-21/22/23系列新型常规潜艇突破了传统的潜艇设计理念,处处体现着独树一帜的设计特征。尽管新颖别致,然而它们能否获得外国海军的青睐,是否代表了常规潜艇发展的一种趋势,都还有待观察。
