Development course of supercharger

The earliest patent application for turbocharger was in 1905. Dr. Alfred Buchi of Sulzer Brothers R&D Company applied for the first patent for turbocharger-power-driven axial-flow turbocharger, but in view of the industrial level at that time, Dr. Buchi did not manufacture the first efficient turbocharger product. 191/kloc-0 started construction in winterthur supercharger factory, and in 19 15, a prototype aero-engine supercharger was manufactured, which was driven by engine exhaust. The main purpose is to overcome the negative influence of thin air at high altitude on power. During World War II, the supercharger made by General Electric (GE) lifted the plane to an altitude of 10,000 meters.
