...melt together pig iron, scrap steel, iron ore and limestone. The carbon is oxidized by the oxygen in the iron ore and goes up the stack as carbon dioxide. Other impurities are absorbed by the limestone slag on the surface of the molten iron. U.S. Steel's new "Turbo-Hearth" furnace blows jets of air across the surface of a pool of molten pig iron. The oxygen in the air combines with the impurities, removes them from the iron, turns the iron to low-carbon steel. This method is not very different from the Bessemer process, which blows...
British planemakers, already well ahead of the U.S. in commercial jet transports, are even farther ahead in turbo-prop planes (propellers driven by gas turbines). They have several test planes flying while the U.S. has none, although airmen expect the turboprops to be the short-range plane of the future as well as the intermediate aircraft between current reciprocating-engine planes and jet liners. Last week General Motors announced that it was finally putting the U.S. into the race to develop a turbo-prop transport...
...Britain's aircraft builders showed 180,000 spectators a fleet of sleek new commercial planes that were well ahead of anything the U.S. has in the air or abuilding. Among the 59 new fighter and commercial planes were the world's first jet transport plane, the first turbo-prop (turbine-driven propeller) transport, and other turbo-prop transports ranging from feeder planes to ocean hopping giants. As an added fillip, there was the Brabazon, the world's largest land transport plane, which had been test-hopped only a fortnight ago. Crowed the London Times: "Already America...
...biggest exhibit, Britain had the Bristol Brabazon, whose eight reciprocating engines (later to be replaced by turbo-jets) will carry 100 passengers 5,500 miles at 250 m.p.h. cruising speed, in high-altitude (25,000 ft.) comfort with staterooms, bar, and movies in the lounge. For medium-range flights, Britain had the Vickers 4O-passenger Viscount and Armstrong Whitworth's 31-passenger Apollo, both turboprops. For feeder-lines, it had both De Havilland's reciprocating engined Dove (eight to eleven passengers) and Handley Page's 22-passenger turboprop, the Mamba Marathon.* But the star of the show...
...addition, Britain has just finished the big, experimental 60-passenger turboprop, the Handley Page Hermes V, and is completing the giant Saunders-Roe Princess, a lo-engined turbo-prop flying boat designed to carry 105 passengers transocean to South America...
