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.
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 ...

The engine was first tested on the Pratt & Whitney Boeing 747SP on July 11, 2008 through mid-August 2008, totaling 12 flights and 43.5 flight hours. [14] It then flew starting October 14, 2008 on an Airbus A340-600 in Toulouse on the number two pylon. [15] Testing of the CSeries bound PW1524G model began in October 2010. [16]
There were some odd-looking craft that resembled powered Frisbees. Some control line models such as the Douglas A-1 Skyraider and some Ryan primary trainers had three control lines or some other form of throttle control, as well as elevator control. The TD-1 was a very popular model in the 1950s.
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.
The Zubr-class landing craft has a cargo area of 400 square metres (4,300 sq ft) and a fuel capacity of 56 tons. [3] It can carry three main battle tanks (up to 150 tonnes), [ 8 ] or ten armoured vehicles with 230 troops (up to 131 tonnes), [ 8 ] or eight armoured personnel carriers of total mass up to 115 tonnes, or eight amphibious tanks or ...
[8] [9] The first ion-propelled aircraft to take off and fly using its own onboard power supply was a VTOL craft developed by Ethan Krauss of Electron Air in 2006. [10] His patent application was filed in 2014, and he was awarded a microgrant to support his project by Stardust Startups in 2017. [ 11 ]
