Today few airliners fly high enough to meet the jet stream, which seldom comes lower than 25,000 ft. But future airliners-especially the jets, which must fly high to save fuel-will have to take account of it. A battle with the jet stream can exhaust their fuel reserves. There is another reason for knowing where a jet stream is likely to be encountered: all fast-moving bodies of air are apt to be associated with turbulence which makes a 500 m.p.h. airplane bounce like a speedboat on a choppy...
Made out of a stock-model Rover, the Whizzard has three chrome-decorated air intakes in its sides just ahead of the rear fenders. The engine, placed behind the driver's seat, has two exhaust vents. The car, which looks much like an ordinary car on the outside, is not jet-propelled. Its fuel burns in two combustion chambers, producing a gas stream that spins a high-speed turbine. The gas escapes upward at rather low speed while the turbine turns the car's rear wheels through reduction gears and a conventional rear...
...only in a monstrous test chamber at the Wright plant at Wood-Ridge, N.J. Compressors blow air into the ram jet's nose. Simultaneously, three steam "ejectors,"' fed with steam from the plant's main boilers, pull combustion gases out of the ram jet's exhaust. By regulating the compressors and ejectors, the engineers can feed the ram jet with air of almost any speed and density. It is no trick at all to make it act as if it were speeding 2,000 m.p.h. at an altitude of 15 miles...
