Summary

This paper examines the problems involved in designing the combustion system of a ram-jet motor for mounting on the tips of helicopter blades. Although sufficient knowledge is not yet available for such a motor to be completely designed on the drawing-board, a principle of construction is suggested which should require the minimum of experiment and development. The principle is illustrated by consideration of a 60 h.p. motor for a tip-speed of 650 ft./sec.
