...Since radial air-cooled engines began to supplant other types, their power has been steadily stepped up by supercharging, higher compression, stronger parts and fuels with higher octane rating. Pratt & Whitney began to think that not much more could be asked of radial engines in single nine-cylinder banks. Since 1929 they have been tinkering with 14 cylinders in two banks, with smaller bores and lighter, more frequent power impulses...
...Timkens were among the first to discover the advantages of the roller bearing over the ball bearing. Their ace product today is the Timken tapered roller bearing (i.e. larger at one end than at the other). This simple device is of prime importance to automobiles where radial and thrust loads are encountered simultaneously in road curves, twists and shocks. Timken tapered roller bearings are standard equipment on nearly every car except those of General Motors which has its own New Departure and Hyatt bearings. Timken also makes bearings for other industrial uses. Its most significant recent milestone was the locomotive...
...dive brought Builder Northrop the biggest Army aircraft order in years - no attack planes at a cost of $1,896,400. The new Northrops all-metal, low-wing monoplanes have a topspeed of nearly 280 m.p.h., will probably be powered with the new Pratt & Whitney Twin Wasp double-bank radial engines. Well pleased at his bargain was Builder Northrop as he handed Pilot Breese $8,000 for his 15 seconds' work...
...from Chicago's Curtis-Wright-Reynolds Airport at 2:02 a. m. one morning last week shot Lieut.-Commander Frank Hawks in a big all-metal Northrup mono- plane, powered by a 700 h. p. Wright engine, the first 14-cylinder, two-row radial engine in commercial use. At 4:22 p. m. a day later he set his plane down on the same field, climbed stiffly out to the cheers of opening day spectators at the Chicago Daily News-sponsored International Air Races. ''I'm not a bit tired," said he, despite the fact that...
...returned to Purnea with a report of "reasonably satisfactory" flying conditions in the Everest vicinity. That was all the Britons were waiting for. The two specially built Westland planes, shipped by boat from England and powered with supercharged Bristol Pegasus radial motors whose propellers had been torqued to provide maximum power development at 13,000 ft., were rolled out at 8:25 on Lalbalu airdrome. Into one stepped Douglas Douglas-Hamilton, Marquess of Douglas & Clydesdale. To focus the motion picture camera, fixed, electrically heated and aimed blind earthward, Col. L. V. S. Blacker, Wartime aviator, climbed into the fuselage...
