...invisible and well-nigh invulnerable to enemy attack. The sunken silo at Vandenberg is only one part of a subterranean complex under construction as Titan's first "hard base." Adjoining the missile tank are other sunken cylinders (see diagram), housing air-conditioning and hydraulic equipment, a power station, liquid oxygen and fuel tanks, and a command control center for the launch crew. Tunnels connect the widely dispersed elements, but after the alert, only the control center will be occupied. Remotely controlled, the monster, fueled and armed, will rise majestically to the surface as the massive doors open, go through...
...rocket fuel combines a chemical that oxidizes and an ingredient that burns. The propulsive energy released is measured as "specific impulse." Present combinations, e.g., liquid oxygen and kerosene, have a specific impulse of about 245 Ibs. Using liquid fluorine as the oxidizer instead of liquid oxygen would boost specific impulse to between...
...fluorine, most tricky of the halogen series (others: 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...
Flameproofing. A liquid flameproofing that is colorless, odorless and harmless to most fabrics' quality and color, but which withstands 1800° flame, was put on sale by the International Flameproofing Corp. of San Antonio. Price...
