Parsons Marine Steam Turbine Company company. In 1944, Parsons was one of 19 companies which formed the 'Parsons and Marine Engineering Turbine Research and Development Association', usually known as Pametrada. The last ship to use a Parsons propulsion system was launched in 1964. The company was absorbed into C. A. Parsons and Company and survives in the Heaton area of Newcastle as part of Siemens, a German industrial conglomerate. Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company was a British engineering company based in Wallsend, North East England, on the River Tyne. The company was founded by Charles Algernon Parsons in 1897 with
Gas turbine on and off to run it only at high efficiency. The emergence of the continuously variable transmission may also alleviate the responsiveness problem. Turbines have historically been more expensive to produce than piston engines, though this is partly because piston engines have been mass-produced in huge quantities for decades, while small gas turbine engines are rarities; however, turbines are mass-produced in the closely related form of the turbocharger. The turbocharger is basically a compact and simple free shaft radial gas turbine which is driven by the piston engine's exhaust gas. The centripetal turbine wheel drives a centrifugal compressor wheel through
