The 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 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...
Critical in the engine's 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...
A delta-winged, wasp-waisted Convair F106 interceptor, piloted by Major Joseph W. Rogers of Worthington, Ohio, took off from Edwards Air Force Base and 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...
Pilot Rogers covered the course twice at an average speed of 1,525.95 m.p.h., as measured by radar, tracking cameras and two men lying on their backs on the desert, sighting upward past tight-stretched wires that marked start and finish. The metal skin of the F106 touched 340°...
