Summary

In this paper the thrust of the turbo-jet engine is rigorously defined, and is divided into the three components front external, internal and rear external. The measurement of thrust in static tests and in flight is discussed. Current methods are critically examined and test methods are proposed. Special attention is given to a method of calculating flight performance from simple static tests with different nozzle areas. A convenient form of engine curves for static tests is shown and a method of flight testing is given.
