Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.
The aircraft used a 4-cylinder piston engine to power a rotary compressor which was intended to propel the craft by a combination of suction at the front and airflow out the rear instead of using a propeller. Contemporary sources describe the Coandă-1910 as incapable of flight. [6]
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 the inlet is increased by the pump ...
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound.
This aircraft, which would be designated He 178, was designed around von Ohain's third engine design, the HeS 3, which burned either diesel fuel or gasoline. [4] [5] To support the programme, the HeS 3 was test flown in a Heinkel He 118, but only as a supplemental engine to the conventional piston engine that it retained. [6] [7]
Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion.The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails.
