...instrument is an accelerometer -a container holding a weight that can move, against springs, toward one end or the other. The weight acts like a man's head that is jerked back because a cab driver starts suddenly. The weight thus measures a vehicle's thrust (acceleration), and from this information, an electronic computer can determine the vehicle's velocity. Inertial navigation uses two accelerometers, one to measure all north-south motion from the starting point, and one to measure all east-west motion...
...bridge players are neither the relentlessly bold nor the incorrigibly careful, but those who know, through a fine combination of card sense, experience and clear thinking, when to be bold and when to be cautious. Old Pro Charles Goren, apostle of point-count bidding, has made many a bold thrust over the years, but in the American Contract Bridge League's yearly Life Masters Pair tournament at Bal Harbour, Fla. last week, he showed that caution some times pays...
...Atlas attempt last month had ended in an ignominious mid-air explosion two minutes after launch. No such trouble dogged last week's test. With the loudest bull bellow the cape has heard yet, the Atlas rose from its pad on 360,000 Ibs. of thrust (150,000 each from the two out board booster engines, 60,000 from the central sustainer). Hitting mach 10 just 132 seconds up, the boosters abruptly shut off and dropped away with their skirts. The central sustaining engine roared another 120 seconds or so, shoved the missile to its apogee 400 miles...
Weighing the size of Russia's Sputniks, U.S. experts have surmised that the Russians may have a massive, single-chamber rocket engine for which the U.S. has no match. The U.S.'s most powerful engine develops only 150,000 Ibs. of thrust, is made by Rocketdyne Division of North American Aviation, Inc. for the Thor and Jupiter (the considerably larger Atlas uses a cluster of engines). Last week Rocketdyne was starting work on an Air Force contract for developing a monster engine with 1,000,000 Ibs. of thrust...
...five years, but it will not require any new scientific breakthroughs. The present Thor engine, which is about as big as a small sports car, will be scaled up to about three times as big. New alloys (probably tungsten-molybdenum-nickel) will be needed for the walls of the thrust chamber, whose temperature will rise from 1,000°-1,200° range to the 1,800°-2,000° range. Combustion-chamber pressure will rise from the current 300-500-lb. range toward 1,000 Ibs. per sq. in. The turbopumps that deliver fuel to existing engines demand...
