Army Air Forces requested an engine with high takeoff power and low fuel consumption for a yet-to-be designed long-range bomber and transport. In World War II, the US Navy specifically ordered aircraft with radial engines because they were more compact length-wise and that meant more planes could be fit on the deck. I noticed that from WWI to WWII, and from early WWII to the end of WWII, the front intake area of radial piston engine aircraft was getting smaller and smaller. The designs are: Inline, as in most car engines today – and in older aircraft engines (think DH Gipsy Major); Vee engines, such as pioneered by the Ford V-8 – and the Rolls-Royce Merlin; and So they have figured things out. And without pressurization, you get that horrible smell when taxiing. Why did WW2 bombers use radial engines? The bomber typically needed efficiency, reliability, and system survivability, and was usually equipped with air-cooled radials. This includes B707 and DC-8 and many other jet aircraft of the 1960's. Trainers and utility aircraft needed low power and high reliability, and received both air-cooled radial and inline engines. Apr 11, 2014 · $\begingroup$ You can make a "puller" jet, but no one does.
