The turbojets of the day were very poor and were on the minus side of thrust to weight ratio and MAC tried to overcome this very creatively.
Tailspin Turtle said:To oversimplify, McDonnell had been asked by the Navy to design a airplane around the nascent Westinghouse axial-flow jet engine. The first test article was intentionally small and it fit within the wing, which was interesting. The problem wasn't thrust to weight, but simply the amount of thrust, which meant several engines. However, McDonnell thought to ask if the engine could be scaled up and the answer from Westinghouse was yes, of course. The FD-1 was the result.
