...Turbojet engines are fine for fast fighter planes and fast, short-range bombers. But in long-range bombers and commercial airplanes there is much to be said for the dependability and fuel economy of the old-fashioned piston-and-propeller engine...
After reading your article [TIME, Aug. 9] concerning turbojet engines with speeds to Mach 4 and plus (enabling a pilot to lunch in New York and then fly to Honolulu to breakfast on the same day), I am prepared to give ground (or sky) to the future "zoomies." As a former Navy fighter pilot I had heretofore considered our navigation and power plant problems more difficult than would be our successors' with their simple jet engines and new navigational aids. [But] the pilot of the future will need a chronometer that runs backwards and is inscribed Yesterday, Today...
...behavior of an airframe in the transonic region is still a frightening unknown. But designers are working hard and hopefully. They are sure that by the time they have the proper airframe, they will have engines with plenty of power for the job. Engine men predict confidently that turbojet engines will work efficiently at least as high as Mach 1.5 (1,145 m.p.h...
...stovepipe" before its proper design was found to be enormously difficult. The ramjet does look simple. It is a hollow cylinder open at both ends and subtly shaped inside. When it is moving rapidly, the air coming in the nose is compressed as if by the compressor of the turbojet. Fuel is burned near the point of highest compression. The energy added to the compressed air by combustion shoves a jet of hot, high-speed gas out the rear end with a noise like thunder. There is nothing inside a typical ramjet except fuel nozzles and a gridlike "flame-holder...
...safe to watch the fires kindle. *The power of jet engines is measured in pounds of thrust. The propulsive horsepower developed varies with the speed. At 375 m.p.h., one pound of thrust equals one "thrust horsepower." * Spruce, tweedy Whittle, 41, comes nearest to being the inventor of the turbojet. Recently the British Labor government, with a grand Old Regime gesture, handed him a tax-free thank you of ?100,000. *Pronounced mack. Named after Austrian Physicist Ernst Mach...
