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
Steam turbine compressors and other shaft driven equipment, to turbines used to generate electricity. There are several classifications for modern steam turbines. Turbine blades are of two basic types, blades and nozzles. Blades move entirely due to the impact of steam on them and their profiles do not converge. This results in a steam velocity drop and essentially no pressure drop as steam moves through the blades. A turbine composed of blades alternating with fixed nozzles is called an impulse turbine, , Rateau turbine, or Brown-Curtis turbine. Nozzles appear similar to blades, but their profiles converge near the exit. This results in
