Close study of the Bison's air intakes, which are 6 ft. in diameter, has convinced some experts that the new Russian engines are merely large, clumsy turbojets built on old principles and probably rather inefficient. Others draw a less comforting conclusion: that the large intakes point to bypass engines, a much discussed type that may prove ideal for long-range, high-speed bombers...
...bypass engine is an intermediate type that stands midway between the turbojet and the turboprop. It has two compressors, each driven by its own turbine through its own shaft (see diagram). Some modern turbojets have this arrangement too, but all the air that is compressed passes through the combustion chambers to form the high-speed jet. In the bypass engine, part of the air from the forward compressor flows around the combustion chambers (incidentally cooling trie engine's skin) and mixes with the speeding gas in the tailpipe. It cools the stream and slows it, but adds greatly...
Range & Quiet. Bypass engines are hard to design, and few of them have been built. Probably the leading model is the British Rolls-Royce Conway, which has been ordered for the Vickers 1000 airliner. Critics say that it does not bypass enough air to yield full efficiency, but Rolls-Royce claims that it will give top range and safety to airplanes flying above the practical speeds of turboprops...
...thunderhead, eased upward over the backstretch. The racket of racing engines sounded loud against the tense and quiet crowd. Reason for the yellow lights: a four-car pile-up that had jammed the track ahead of Wild Bill Vukovich. All the luck in the world was not enough to bypass disaster. Vuky never had a chance. His Hopkins Special plowed into the tangled wreckage at 150 m.p.h., bounced into the air, caromed off a parked car and clipped a utility pole. Then it landed on its back and burst into flames. Bill Vukovich was almost certainly dead before his wheels...
...Peoria & Western Railroad from the estate of George P. McNear Jr., whose death by a shotgun blast during a 1947 strike is still unsolved. With the 239-mile T.P. & W., which bridges central Illinois and ties in with the Santa Fe tracks at Lomax, Ill., the Santa Fe can bypass crowded Chicago switchyards with transcontinental freight, save up to eight hours on New York deliveries...
