Which country invented the first impulse steam turbine?

1882, the first single-stage impulse steam turbine was manufactured in Laval, Sweden. The first steam turbine with practical significance was 1884 multistage reactive steam turbine made by Parsons, England. It uses the reaction principle to make the turbine rotate, but the power is only 7.5 kilowatts. Soon, he made each 1000 kw steam turbine for power generation; 1896, several single-stage impulse turbines were connected in series in Latour, France, to form a multi-stage impulse turbine; In the same year, Curtis of the United States also obtained the invention patent of steam turbine. He supplied the kinetic energy of steam to two rows of moving blades in two parts, so the rotation speed was lower than that of Laval's single-stage impulse turbine. The further development of steam turbine is to combine shock and reaction to improve the performance of steam turbine. Modern high-speed aircraft mostly use jet engines. The principle is that air is inhaled, mixed with fuel, ignited, and the air after explosion and expansion is ejected backward, and its reaction force pushes the plane forward.
