...goes on, day after day, from east to west, scorching relentlessly. The earth cracks up and deep fissures open their gaping mouths; but there is no water-only the shimmering haze at noon making mirage lakes of quicksilver . . . The sun makes an ally of the breeze. It heats the air till it becomes the loo and then sends it on its errand. Even in the intense heat, the loo's warm caresses are sensuous and pleasant. It brings up the prickly heat. It produces a numbness which makes the head nod and the eyes heavy with sleep. It brings...
...CHICAGO FIRE. Half the West Side bursts into flame every 20 minutes, and who is it but Mrs. O'Leary there, coming out of the heat with an actual cow-trained to moo at crowds. Spectators are called upon to help firemen squirt the blaze from a hand-pump engine. Meanwhile, a cool operator in a fireproof booth turns up the hidden gas jets, then slowly turns them down as the fire subsides, leaving on view the pre-charred timbers of skeleton buildings...
Snub Nose. The easiest, fastest cone to develop was the "heat-sink"' type, made of thick copper. Since copper is an excellent conductor of heat, the cone's front surface could stay solid until the whole mass was near the melting point. To many, it seemed obvious that a nose cone should be made slim and sharp-pointed, capable of piercing the atmosphere with low resistance. But the contrary proved to be the case. Dr. H. Julian Allen of the National Advisory Committee for Aeronautics argued conclusively that a blunt nose was better for the heat-sink cone...
Flaming Arc. Thus, even while the heat-sink cones were still being tested, both G.E. and Avco started work on a new kind of cone. It was deliberately designed so that some of its material would be "ablated"-vaporized and blown away into nothingness by the intensely hot air through which it raced. Ablating cones promised a weight advantage, but not even the shock tube was adequate to test them at the research level. Therefore a new testing device, the arc wind tunnel, was tailored...
...ablating nose cone is the design of the present. It is longer and more pointed than its heat-sink predecessor. It can slice more deeply through the atmosphere before it slows down, giving it greater protection against defensive missiles fired from the ground. Better still, it is comparatively light: the G.E. ablating nose cone used on the "longfellow'' Atlas fired May 20 from Florida to the Indian Ocean probably played an important part in the missile's being light enough to attain its 9,000-mile range...
