Parsons Marine Steam Turbine Company 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 £500,000 of capital, and specialised in building the steam turbine engines that he had invented for naval use. The first ship to use a Parsons propulsion system was "Turbinia", launched in 1894; the successful demonstration of this vessel led to the creation of the company and the subsequent construction of the engines for the first two turbine-powered destroyers for the Navy, and , launched
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
