A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
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 which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and ...
The company develops, designs and produces high performance turbines for primarily for marine applications, boats and fire-suppression pumps. It gained fame and became noted for developing and building what may be the most powerful and fastest street-legal motorcycle in the world, the turboshaft-powered MTT Y2K Turbine Superbike.
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.
While not strictly jet engines in that they rely on an auxiliary mechanism to produce thrust, turboprops are very similar to other turbine-based jet engines, and are often described as such. In turboprop engines, a portion of the engine's thrust is produced by spinning a propeller, rather than relying solely on high-speed jet exhaust. Producing ...
The other boats of this class and HDW's AIP equipped export submarines, Dolphin class, Type 209 mod and Type 214, use two 120 kW (160 hp) modules, also from Siemens. [17] The Type 212 can remain submerged for 21 days; one such submarine conducted a 1600 nautical mile journey solely on AIP in 2016.
Turbinia was the first steam turbine-powered steamship.Built as an experimental vessel in 1894, and easily the fastest ship in the world at that time, Turbinia was demonstrated dramatically at the Spithead Navy Review in 1897 and set the standard for the next generation of steamships, the majority of which would be turbine powered.
Two steam powered water pumps and an air compressor pre-1915. The "Marsh" portion of the company name came from Elon Marsh, an engineer at the company. In the 1930s they manufactured the TURBO pump. Today the largest pump they market is the 480 Vertical turbine pump. The company is considered a major pump manufacturer and key pump design developer.
