...Allison-engined, 360-m.p.h., low-winged monoplanes, reputedly armed for the British with six machine guns...
...importance of this fact was that last year the Army, fed up with the air resistance of air-cooled radial engines (their "built in head winds''), all but abandoned them for fast fighter craft, ordered the bulk of its fighters equipped with Allison 1,090-h.p. liquid-cooled inline engines. Meanwhile Pratt & Whitney and Wright Aeronautical, top-flight U. S. engine builders, stuck to air-cooled radials (which in-line engine men scornfully call "starfish") and increased their power. Result: Pratt & Whitney is in production with a tremendous single package of power: a 2,000-h.p. 18-cylinder...
General Motors' Allison plant has just got going. It produced 73 engines in July, 65 in August, 223 in September, 286 in October. Many Army pursuit planes built for Allisons came off the line without power plants to drive them, and "bugs" were found in the comparatively untried engine. Built to develop 1,090 h.p., Allisons had to be held to 950 and until this week, when the restriction was finally lifted, Army pilots could not get full performance out of their ships...
...assistance of research-wise National Advisory Committee for Aeronautics, which helped slick the new plane up as no air-cooled job had ever been slicked before. An old flying adage is that "there is no substitute for soup," i.e., horsepower. In soup the new radials were ahead of the Allison by close to 2-to-1, even when the Allison was putting out its full power. Excess power means not only more speed, but better climb, higher service ceiling, more ability to lug the heavy armament load needed in modern fighters...
...Navy's bet on air-cooled engines 7, the Army's bet on liquid-cooled, a lot of money is at stake, in addition to the ultimate excellence of U. S. pursuit planes. The Army has let contracts of $90,500,000 for Allison engines and airplanes to put them in-Curtiss, Lockheed, Bell-and has a stake of $62,448,000 in Packard Motor Co.'s project to build liquid-cooled 1,000-h.p. Rolls-Royces - round total...
