At first, some people wanted to use it as a fuel for internal combustion engines. However, it was too "mild" and could not be used vigorously in internal combustion engines and could not play its role, so they had to surrender to the disadvantage of gasoline.
Later, people discovered that early internal combustion engines also had problems. Like a steam engine, it relies on the reciprocating motion of the piston, and then through the crank and connecting rod, it turns into rotational motion, which is very troublesome. Therefore, some people want to cancel the piston and cylinder and let the gas directly drive the blades to rotate. This idea is like the principle of the ancient revolving lantern in our country. The heat generated by the candles in the revolving lantern drives the impeller to rotate, causing the paper figures and horses to rotate.
In 1872, German engineer Hitot first designed a hot air turbine and obtained a patent. In 1906, French engineers Amengau and Liemali built an experimental gas turbine. By the 1930s, practical gas turbines finally appeared.
In 1928, the British scientist Whittle proposed using the jet from a gas turbine to propel an airplane and proposed the idea of ??a turbojet engine. In 1937, the first jet engine was prototyped. However, it was not until May 14, 1941 that a jet engine was successfully tested on an aircraft in the UK. Two years before this, in 1939, the famous German engineer Oheim was the first to install a jet engine on an aircraft named He178. On August 27 of this year, Germany came from behind and sent the world's first jet aircraft into the sky.
The invention of the jet brought the aviation industry to a new stage. It has since replaced piston aircraft and unified the world of aircraft.
