    • 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.

    • A vessel has a hull (1 Fig. 1) joined to a sound strut (2. Fig. 1) which can bear the weight of the whole vessel. This strut is positioned tendentially behind as to the hull’s centre of gravity, in such a way that the thrust of the propulsion system (for example a propeller, 4 Fig. 1) can annul the bow sinking moment; this moment is generated by the weight of the whole vessel acting on the bottom part of the strut. In fact, a foil (3 Fig. 1) is allocated at the bottom part of the strut, which acts as lifting height plane that is able to pull-up, dive, yawn, turn, roll, and bears the entire weight of the vessel. This height plane with strut is very similar to an overturned airplane elevator. The thrust of the propeller and the position of mobile parts of the height plane maintain the hull of the vessel lifted as to the water surface. Height planes have to be fully immersed to allow the vessel lifted as to the water surface. Height planes have to be fully immersed to allow the vessel not to jerk on the waves. This navigation/motion condition allows the vessel to travel without any drawback or motion sensation that characterize conventional vessels, being insensitive to waves: the part that bears the hull travels under the waves. The vessel is stabilized thanks to several electronic controls and actuators which automatically and instantaneously compensate for every condition and position variation.
    • 船舶具有连接到支撑整个船舶重量的声支柱(2.图1)的船体(图1)。 这种支柱倾向于在船体的重心方面倾斜,推进系统(例如螺旋桨,图1)的推力可以取消弓沉降时刻; 这一刻是由作用在支柱底部的整个容器的重量产生的。 事实上,铝箔(图1)分配在支柱的底部,作为提升高度平面,能够上拉,下潜,打呵欠,转动,滚动,并承受整个重量 船只。 这个带支柱的高度平面与翻转的飞机电梯非常相似。 螺旋桨的推力和高度平面的移动部件的位置使船体的船体与水面相提升。 高度平面必须完全浸入,以使船只抬起水面。 高度飞机必须完全沉浸,以使船只不要在波浪上晃动。 这种导航/运动条件允许船舶行进而没有任何缺点或运动感觉,其表征常规船只,对波浪不敏感:承载船体的部分在波浪下行进。 由于几个电子控制和执行器,船舶稳定,自动和瞬时补偿每个条件和位置变化。
