...belly of the high-wing jet will be only 50 in. above the ground, so that trucks can easily be driven through its large tail door into its air-conditioned, pressurized cargo hold. Power from the four Pratt & Whitney turbofan engines will be great enough to lift the plane off 6,000-ft. runways with a 50,000-lb. load, making it possible to fly in and out of fields all over the world. It will fly the Atlantic with a 60,000-lb. load, the vaster Pacific with a 20,000-lb. load. The plane will be built...
...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...
Engineers have long known that the turbofan is the most efficient engine for subsonic aircraft. Rolls-Royce pioneered turbofan development, turned out a prototype of its famed Conway by-pass engine in 1950. But U.S. enginemakers, under pressure from the military to produce regular jet engines that are more efficient at supersonic speeds, lagged behind...
...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...
...Near San Francisco, the Federal Aviation Agency is building an ultramodern, $5,000,000 radar air-traffic control center, whose Remington Rand electronic brain will track all aircraft in a three-state zone. Hardest-to-lick problem thus far is jet noise, but airport officials hope that the new turbofan jet engines will eventually alleviate even that drawback of the jets. Dulles Airport is planting 80,000 trees around its rim to help absorb jet noise...
