...second generation of solid-fuel missiles, designed for mass production and mass deployment through the mid-1960s, must have smaller, higher-yield thermonuclear warheads to fit their smaller nose cones. The Navy's Polaris engineers managed to test their bird's initial warhead just before the moratorium, but could not test its higher-yield follow-up warhead; the Air Force's Minuteman (see SCIENCE) and the Army's Pershing are being developed at a cost of millions to fit warheads that have not been tested, and, under the moratorium, may not be. All these tests could...
...From Nose Cones. Most of the electricity generated by the system comes from the electrodes, but waste heat can be harnessed to drive a conventional turbogenerator, adding importantly to the system's efficiency. Overall, Avco scientists estimate that a 450,000-kw. coal-fired MHD generator will produce electricity with the sensational thermal efficiency of 55%. The best that conventional plants...
...Huff is an unassuming extravert with a reputation as a waitress kidder, a dislike for liquor (two beers make him woozy), and a quiet determination to get to bed around 10 every night. But the game has left more of a mark on him than the slightly twisted nose in his handsome, square-jawed face. Sometimes he worries that the mean streak he works up for his profession of violence will affect him permanently. "You've got to watch that you don't take it off the field with you," says Sam. "You get guys...
...laboratory and in industry. It is soft enough to be a good dry lubricant; its high heat resistance makes it a good material for crucibles and as a moderator in nuclear reactors. In the new age of rocketry, scientists have eyed it for use in rocket nozzles or in nose cones, which must resist the heat of reentry. But ordinary graphite has two faults: it is permeable to gases and is structurally so weak that it crumbles when subjected to high-velocity rocket exhaust...
Pyrographite can be deposited in sheets up to ½ in-thick, can be shaped to form rocket nozzles and caps for nose cones. Both these parts get punishing heat concentrated on rather small areas. The beauty of Pyrographite is that it conducts heat away from these danger points as fast as copper can, but it does not permit nearly as much heat to pass through it. A Pyrographite nose cone, for instance, spreads the heat of air friction over a large area and permits it to be radiated harmlessly away, but it does not let heat strike through the cone...
