Like one of the fastest airplanes that ever flew,† the two-man Japanese submarines which attacked Pearl Harbor had contrarotating propellers -two tandem screws placed close together, turning in opposite directions. Blades on the second screw are pitched counter to those of the other screw so that both thrust in the same direction. Such devices for U.S. warplanes were announced last week to be "in the developmental stage" by Curtiss-Wright, United Aircraft, other plane builders...
Purpose of this mechanism in planes (and submarines) is to overcome torque or sideways twist created when 1) the air's resistance to the rotating screw makes the engine tend to rotate the plane itself, 2) the whirling air stream behind the propeller hits the lifting surfaces at a skew angle. Torque must be counteracted by ailerons and rudder, especially in small planes whose bodies-like those of small submarines-do not in themselves provide enough stable ruddering...
Part of a six-section exhibition, the works of these men include, among others, Sargent's "Arras Cathedral, "Garden of Florence," the water colour "Terminal State," Hassam's "General Andrew Jackson," "World's Fair, Chicago 1892," "Old Dutch Church, Fishkill," and La Farge's "Samoa," and "Turn of the Screw...
...multiplied astronomically impossible figures by five and hoped that each figure would show up as something hard, tangible, useful or deadly: a tank, a gun, a ship, a plane, a truck, a tent, a uniform, a mess kit, a blanket, a parachute, a monkey wrench, a lathe, a screw...
...lathe (a machinist's first lesson) in six to eight weeks at school. Then he graduates to a factory, begins at once to produce on his lathe. Thereafter he progresses, under instruction from a factory foreman and in night school, to drill press, shaper, planer, grinder, milling and screw machine. Advantages of this system: 1) training is much faster, 2) trainees produce while they learn, 3) fewer teachers are needed...
