Abstract
The author points out that the turbo-jet engine can no longer satisfy the demands of the modern world; he therefore describes briefly the various types of engines under study at present in certain countries. These fall into two main categories: (1) Supersonic aircraft engines, which include a turbo-fan after-burner engine, a turbo-fan ram-jet combination, and a turbo-rocket engine. (2) VTOL jet engines which do not need long runways, including a turbo-jet lift engine, a turbo-fan lift engine, a conventional turbo-jet engine with a lift fan attachment, and a deflected lift engine. A reheating gas turbine engine which has the advantage of a low fuel requirement is also briefly described. (Author)
