Composite‐Engined Aircraft as a Basic Conception: An Outline of the Design Considerations that Led to the Conception of the Ryan Fireball

BY way of introduction we shall explain that we have used the rather unwieldy term “composite‐engined aeroplane” to define the type of aircraft with which we at Ryan are working. This is one having two power plants of different kinds, which are, in the FR‐1, Fireball, a nine‐cylinder Wright Cyclone engine of 1,820 cubic inches piston displacement and a General Electric 1–16 turbo‐jet engine of 1,600 pounds static thrust.
