...Fundamentally bombardment is the core of air attack. Bombers do the damage; other planes simply find and clear the way. Main requirements of bombers are speed, range, capacity. Germany's Dornier Do. 17 and Heinkel He. 111 combine these talents admirably. The slender Do. 17, equipped with two liquid-cooled, streamlined, inverted-V Daimler-Benz engines, can lug one ton of bombs 1,500 miles at nearly 300 miles an hour; and the Heinkel, produced at Germany's model factory at Oranienburg (where duplicate machinery is set up underground, where workers live like prep-school boys), can carry...
...fighters is the Curtiss P-36, of which she bought 200. Its 275-300 m. p. h. are not enough. Its air-cooled engine, offering considerable wind resistance ("like running for a trolley car with your overcoat open," says Al Williams), does not streamline as neatly as liquid-cooled power-plants. However, the French have repeatedly expressed themselves satisfied with the P-36, and have claimed that it even outfights the Messerschmitt, being more maneuverable...
Foremost U. S. rocketeer is Dr. Robert Hutchings Goddard, who, backed by Guggenheim funds, runs a rocket-experiment station in the New Mexico desert. In his early experiments taciturn Dr. Goddard used ordinary gunpowder for fuel, has since switched to liquid fuels, such as a mixture of oxygen and gasoline, or oxygen and hydrogen-tricky to handle but highly efficient. He has sent rockets up vertically to heights of a mile and a half. His chief interest in rockets: as a possible means of carrying scientific instruments up higher than stratosphere balloons can take them. But experimenters abroad, especially...
Today, engines for big ships are produced by only three U. S. factories: Pratt & Whitney (at East Hartford, Conn.) and Wright (at Paterson, N. J.), which produce radial, air-cooled engines, and General Motors Corp.'s Allison Engineering Co. (Indianapolis), which is just getting into production on liquid-cooled inline motors. If there is ever a bottleneck in the production of aircraft for war it will be in the compact engine business, but last week it did not appear close. For Pratt & Whitney and Wright had finished their expansions for wartime business, were operating at no more than...
Last year horrified reports cropped up that liquid oxygen was being used to fill bombs of dreadful killing power. An article in Massachusetts Institute of Technology's Review pooh-poohed this bogey, on the ground that liquid oxygen explosives are so sensitive that they cannot safely be transported from place to place, and that they deteriorate rapidly, losing their explosive power in an hour...
