Proceedings of the Institution of Mechanical Engineers, 1947
Mechanical flight began just over 40 years ago, and the only system of propulsion in use until five years ago was the internal combustion piston engine driving a propeller. Quite suddenly, the internal combustion turbine has come very much to the fore, both with and without a propeller, giving an increase in speed from under 500 to over 600 m.p.h.—a ...
