🛫 History of the Turbofan Engine

The history of turbofan engines begins with the German Daimler Benz DB 670, which was the first to run on a test bed, designated 109007 by the Nazi Ministry of Aviation and first tested on May 27, 1943. The British Metrovick F.3 turbofan followed, utilizing the F.2 turbojet as a gas generator with exhaust discharging into a close-coupled fan module. In around 1960, Rolls Royce introduced the Conway, the world's first production turbofan with a bypass ratio of 0.3, similar to the modern General Electric F-404 fighter engine. The Soviet Union's first airliner powered by turbofan engines was the Tupolev Tu-124, introduced in 1962, which used the Soloviev D-20 engines. Today, high bypass turbofan engines are the prevalent design in commercial aviation, especially in business jets.
