While gas turbines offer important advantages over piston engines (e.g., cheaper fuel, less vibration and fewer moving parts), they also gobble fuel greedily and generate terrific heat, notably from the exhaust. To solve both problems, Chrysler engineers devised a heat exchange that transfers heat from the exhaust gases to the incoming air. The system not only cools the exhaust but saves fuel, since the intake air is preheated before it reaches the combustion chamber. As a result, says Chrysler, the new engine delivers as many horsepower-miles per gallon of gasoline as a standard automobile engine, and the exhaust gases...
...explorations know neither time nor place, nor government nor business contract. He has written books on Thucydides. the rise of cities, on the Jacobins, Joyce, and juvenile delinquents. He has composed Pulitzer Prizewinning poems (The Conquistador by Archibald Mac-Leish) and music (Symphony No. 3 by Walter Piston). In the person of Harlow Shapley, he has given a new view of the geography of the universe, and through Paul Mangelsdorf, he has helped develop hybrid corn. Of Harvard's scientists, six have won Nobel Prizes.* Its chemists, biologists, and physicians have invented the iron lung, developed a treatment...
...first made his mark as a specialist in aircraft carburetors, is conceded to be one of the world's top aviation engineers. He started late in jets, because Pratt & Whitney, United's engine-manufacturing division, had to concentrate exclusively on the production of conventional piston engines during World War II. When United finally got going in 1946, Hobbs decided to leapfrog the competition by mapping out an engine far more powerful than anything on any other firm's drawing boards...
...Billion Feast. At present, Hurley uses the new line only for the 3,500-h.p. Wright Turbo-Compound piston engine, which powers the Fairchild Packet, Lockheed Super Constellation and Douglas DC-7. But Hurley wants to use it for all Curtiss-Wright's new and secret family of jets and turboprops. There are two new Air Force turboprops, the T47 and T-49, under tight security wraps: both are reported to turn out more than 12,000 h.p. Curtiss-Wright is also testing a jet engine of great power called the J-67, which develops well over...
