...such tricks as running through ankle-deep sand and sprinting up and down an 80-ft. sand dune 40 times a day or more. To give Elliott the energy to run 25 miles a day, Cerutty stoked him with oats, nuts and fruits. He urged his pupil to "thrust against pain and be contemptuous...
...trick was done by breaking up the jet stream and funneling it through 21 narrow after tubes instead of one big tube. "The big, doughnut-shaped exhaust roar," said a Boeing engineer, "was broken down into 21 smaller, bagel-sized noises." The loss in efficiency: only 2% loss in thrust (v. up to 20% in earlier supressor devices), plus a 2% increase in fuel...
...Three engines burning furiously, an Air Force Atlas missile shot into the sky on a successful but limited (3,000 miles) test flight. It was the third fully powered (360,000-lb. thrust) flight for the 6,000-mile-plus ICBM. In preparation: a full-range shot, early this fall...
...iodine, bromine), is a nightmare to handle and hideously corrosive. To stay liquid, it must be kept at - 306° F., and if it merely touches water it will start a 5,000° F. explosion. Now Bell says it has actually harnessed this violence, even in small rocket thrust chambers. The chambers were specially designed laboratory chambers. Their metals are still classified, and so is the ingredient used with fluorine (possibly ammonia or hydrazine). Very special handling also involved unusual welding techniques, new storage tanks, refrigerated pipelines...
...missilemen are unlikely to go to such trouble for some time, though the news last week gave thrust to Bell stock on Wall Street. Trouble is that using liquid fluorine would mean redesigning present ICBM engines, which run well enough on more placid fuels...
