The invention discloses a drag reduction system and method for an underwater vehicle, and belongs to the technical field of surface drag reduction of underwater vehicles. Comprising a ventilation module, a resistance reduction module and a gas recovery module which are sequentially arranged from the head to the tail of the aircraft. The ventilation module is used for introducing gas to the peripheral surface of the aircraft; the drag reduction module is a drag reduction surface arranged on the peripheral surface of the middle section of the aircraft and can convert the gas exhausted by the ventilation module into a drag reduction gas film layer covering the peripheral surface of the aircraft; the gas recovery module sucks gas in a gas film layer on the periphery of the tail end of the aircraft into the cabin, a water-gas mixture sucked into the cabin is treated to obtain dry gas, the treated gas is conveyed to the ventilation module through a pipeline to be recycled, and separated water is discharged out of the aircraft through a drainage pipeline. The problems of gas loss and bubble wake existing in the existing underwater vehicle ventilation resistance reduction technology are solved.
本发明一种水下航行器的减阻系统及方法,属于水下航行器表面减阻技术领域;包括航行器从头部到尾部依次设置的通气模块、减阻模块、气体回收模块;所述通气模块用于向航行器外周面通出气体;所述减阻模块为设置于航行器中段外周面的减阻表面,能够将通气模块通出的气体转化为覆盖于航行器周面的减阻气膜层;所述气体回收模块将航行器尾端外周气膜层内的气体吸入舱内,对吸入舱内的水气混合物进行处理得到干燥气体,将处理后的气体通过管道输送至通气模块进行重复利用,分离出的水分经排水管道排出航行器。本发明克服了现有水下航行器通气减阻技术存在的气体流失以及气泡尾迹的问题。
