...whole engine is an ingenious exercise in mechanical geometry. As the rotor turns, its corners form three moving cavities that first increase in volume and then decrease. When a cavity, still small but growing, passes the intake port leading to the carburetor, it draws in fuel and air. Then the cavity decreases in volume, compressing the mixture. The engine's single spark plug fires; the exploding gas pushes the rotor and shaft. At the end of the power stroke, a corner of the rotor uncovers the exhaust port, and the burned gases are swept out of the engine. Meanwhile...
...Wankel engine is not as efficient as a diesel, but its makers say that its fuel consumption is about the same as the economical Volkswagen. The most extraordinary thing about it is its small size. A 28.6-metric-h.p. model is 8 in. in diameter, 6 in. long, weighs only 22 lbs. The Volkswagen engine has about the same horsepower, but is many times bigger and weighs...
...design were the metal "piston rings" at the tips of the triangle that keep the chambers gastight. But NSU says the metal strips show no wear after 300 hours of fullspeed operation. The engine uses a conventional carburetor and can be made to burn many kinds of fuel, including diesel oil. It is not for sale yet, but NSU expects to have it debugged and in large production in about two years...
...climbed to 40,000 ft. (jets are slow at low altitude). Air conditions were ideal; the aircraft and its Pratt & Whitney J-75 engine were new but carefully chosen. In earlier tests, the engine had been revved up until its temperature reached the highest permissible level, and the fuel-input control was set at that point...
When Rogers reached 40,000 ft., he leveled off, and a ground radar guided him toward the 18 km. (eleven mile) course that is specified by the F.A.I. (Fédération Aéronautique Internationale) in Paris. He lit the afterburner and opened the fuel control to the limit. Quickly, the ship accelerated past Mach 2 (twice the speed of sound). The F.A.I, specifies that an airplane trying for a straightaway, level-flight record must not climb or dive more than 164 ft. over the course. To respect these narrow limits at better than 1,500 m.p.h...
