The invention provides a dry ice anti-drag drape for an underwater vehicle and a preparation method of the dry ice anti-drag drape. The dry ice anti-drag drape is made of metal fibers and a dry ice composite material. The dry ice anti-drag drape wraps the aircraft shell and is matched with the aircraft shell in shape. According to the method, carbon dioxide supercavitation covering the vehicle is generated in a dry ice rapid sublimation gas production mode, the vehicle is isolated from water, and the purpose of efficient drag reduction is achieved.

    本申请提供一种水下航行器干冰减阻披挂及制备方法,干冰减阻披挂的材料为金属纤维以及干冰复合材料;干冰减阻披挂包裹于航行器外壳,并与航行器外壳形状相匹配。本申请利用干冰快速升华产气方式,产生覆盖于航行体的二氧化碳超空泡,隔离航行器与水,达到高效减阻目的。
