The turbo-jet engine combines the principle of jet propulsion and the gas turbine. These ideas are quite old; as early as a.d. 150 Hero suggested the use of a jet of steam for propulsion, and the first patent on a gas turbine was granted to an Englishman, John Barber, in 1791. Many attempts were later made to produce an efficient gas turbine, particularly in the first quarter of this century, but it was not until the 1930’s that these ideas were combined into a practical aircraft engine. One man in England and several in Germany conceived, more or less simultaneously, the idea of a propulsive jet provided by a gas turbine. The history of the invention of the English turbo-jet will be described first.
