...Astrojet gets its pep from a new engine: the Pratt & Whitney turbofan, which develops 17,000 Ibs. thrust. Basically, the turbofan sucks in a larger mass of air than regular jet engines to produce greater thrust with less fuel. A fan, set just inside the air intake (see diagram), pulls in the air. then blasts about 60% of it out through openings on the side of the jet pod to provide just under 50% of the engine's total thrust. The rest of the air is directed into the engine's burning chamber. The engine produces 20% more...
When American began flying Boeing jets just over two years ago, it had to settle for regular jet engines. Later, Pratt & Whitney developed a way to convert the jet engines on American's planes into turbofans. At a cost of $50 million, American is converting 23 Boeing 707s and ten 720s. The Boeings that American still has on order will also be outfitted with turbofans. By next year American expects to be the only U.S. airline to have its entire jet fleet powered by turbofans...

...Finger Lakes country of upstate New York, and his first ambition was to be a naval officer. Twice he applied for an appointment to Annapolis, twice flunked the math examination. As a child he had always sketched and drawn; he decided to make art his career. He studied at Pratt Institute, the Art Students League, the National Academy of Design. After a stint as a Navy radio operator during World War I, he lived briefly in Paris. The art world was popping with new group movements in those days, but Dickinson chose a path...
...Force rolled out its first B-52H bomber, designed to serve as a launching platform for four long-range (1,000 miles), air-launched Skybolt missiles. The airplane itself is powered by eight new Pratt & Whitney J57 turbofan engines, has a range of 10,000 miles, will be able to launch its atom-tipped Skybolts without having to make deep, dangerous penetrations into hostile airspace. The 6-52-Skybolt weapons system will have one advantage over ground-launched rockets: it can be recalled at any time before it reaches the release point for its birds...
