    • An underwater two-phase ramjet propulsion unit includes an inlet (104) for receiving a flow of water, a compressed gas injector (132, 134) for injecting compressed gas into the flow of water, a mixing chamber (106) for mixing the compressed gas with the water to provide a two-phase flow of working fluid, and a nozzle (108) for accelerating the two-phase working fluid to generate a two-phase jet. The propulsion unit can be implemented with fixed geometry or variable geometry. The propulsion unit includes a supersonic gas injector (132) as well as a subsonic gas injector (134). The propulsion unit includes a control system (110) for controlling the compressor (122), supersonic gas injector (132), subsonic gas injector (134), the geometry of the unit, and the direction of the thrust vector.
    • 水下两相冲压喷气推进装置包括用于接收水流的入口(104),用于将压缩气体注入到水流中的压缩气体喷射器(132,134),混合室(106) 用水提供气体以提供工作流体的两相流,以及用于加速两相工作流体以产生两相射流的喷嘴(108)。 推进单元可以用固定几何形状或可变几何形状实现。 推进单元包括超音速气体喷射器(132)以及亚音速气体喷射器(134)。 推进单元包括用于控制压缩机(122),超音速气体喷射器(132),亚音速气体喷射器(134),单元的几何形状和推力矢量的方向的控制系统(110)。
