基于碳氧循环不依赖空气推进隐蔽排废与反向环控

AIP (Air Independent Propulsion) submarines are the important power of national defense and nuclear deterrence. At present, the exhaust emission of air-independent propulsion system affects sub’s concealment, and the cabin atmosphere environment control system also restricts submarine endurance ability. Using the cold energy of liquid oxygen or LNG loaded on subs, the project will study exhaust gases zero-emission by liquefaction, and the centralized and integrative process of the cabin atmosphere environment control system, which includes various indices of air-conditioning and ventilation, oxygen supply, carbon dioxide elimination, air purification and oxygen recovery. It has a strategic application prospect in the respect of upgrading sub’s concealment and submarine endurance ability. The main contents of study are: ⑴Flow characteristics and energy transfer mechanism of multicomponent and multiphase mixture systems; ⑵Basic principle of reverse design on the multi field coupling of green environmental control; ⑶Multiple processes coupling law of the bionic hyperstructure and adjustment mechanism of the multi-objective parameters. Through the development of hidden exhaust and reverse environmental control of air independent propulsion for ultra-quiet submarine based on carbon and oxygen cycle, and related basic research on energy - bionics - stealth, we will establish the theory framework of the hidden exhaust and green environmental control of the underwater vehicle, as well as the design theory and method of the hyperstructure of exhaust gases management - atmosphere environment control system.

不依赖空气推进（AIP）潜艇是国防建设和战略威慑的重要力量。目前，AIP动力系统的废气排放影响着潜艇的隐蔽性，舱室的大气环境控制系统也制约着水下续航能力。本项目利用潜艇携带的液氧或LNG自身蕴含的冷量，研究对废气的液化封存隐蔽排放，并一体化集中处理舱室大气环境控制的各项指标，即空调通风、呼吸供氧、CO2清除、空气净化与氧气再生，在提升潜艇隐身与水下续航能力方面，具有战略性的应用前景。主要研究：⑴超元多相混合物系的流动特性和能量输送机理；⑵绿色环控多场耦合的反向设计基本原理；⑶超结构多过程耦合规律与多目标参数调节机理。通过开展基于碳氧循环的不依赖空气推进隐蔽排废与反向环控，以及能量-仿生-隐身相关基础研究，确立水下航行器的隐蔽排废-绿色环控理论体系框架，建立废气管理-大气环境控制的超结构设计理论及方法。
