Conventional gasoline engines have a basic fault; their reciprocating parts (pistons, connecting rods, etc.) must be stopped and started thousands of times per minute. This wastes power, and it also calls for a heavy engine to stand up against the battering it gets. Last week NSU Werke motor company of...
Instead of cylinders and pistons, the Wankel engine has a single combustion chamber shaped like a fat-waisted figure eight (see diagram). Inside, it is a three-cornered rotor with curved sides. A shaft passes through the rotor and makes it move on an eccentric orbit by means of two...
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...
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...
