WebApr 16, 2024 · Modern submarine torpedoes come in two variants: thermal and electric. Thermal torpedoes use a fuel, such as OTTO Fuel II, which can be burned without an external oxygen source.A gas turbine or ... A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside … See more A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump … See more Pump jets have some advantages over bare propellers for certain applications, usually related to requirements for high-speed or shallow-draft operations. These include: • Higher speed before the onset of cavitation, … See more Pump-jets were once limited to high-speed pleasure craft (such as jet skis and jetboats) and other small vessels, but since 2000 the desire for high-speed vessels has increased and thus the pump-jet is gaining popularity on larger craft, military vessels and See more The water jet principle in shipping industry can be traced back to 1661 when Toogood and Hayes produced a description of a ship having a central water channel in which either a plunger or centrifugal pump was installed to provide the motive power.
