...Navy: then back to football he went, this time at Miami of Ohio, a small school with an uncanny knack for producing big-time coaches?Army's Earl Blaik and Paul Dietzel, Ohio State's Woody Hayes, the pros' Paul Brown, Weeb Ewbank and Sid Gillman. In 1947, a solid 190-lb. halfback, Ara led the Redskins to an undefeated season, won All-America mention and a pro tryout with the Cleveland Browns...
...years, the loudest noises in the aerospace business have been the rumble of liquid-fueled boosters blasting spacecraft into orbit, the sharper roar of solid-fuel military missiles climbing into their long trajectories, and the continuing, wordy battles between the promoters of each type. Now, back of the racket, can be heard the insistent voice of still another competitor in the rocketry race-the hybrid that manufactures its power by combining liquid oxidant with solid fuel. Detractors may scoff that the hybrid combines all the dangers and difficulties of both solids and liquids. Its champions are confident that...
Fierce Fluid. A typical hybrid is a comparatively simple product of a complex science. It is basically a pressurized tank for liquid oxidizer, behind which sits a combustion chamber lined with solid fuel. The two propellants are usually hypergolic-they ignite spontaneously when they come in contact with each other. A valve permits a jet of oxidizer to squirt into the rear chamber, combustion begins, and a hot, high-temperature flame roars out of the nozzle. The oxidizer valve can be used as a throttle to reduce the thrust and the engine can be stopped and started any number...
...solid rockets the oxidizer and fuel must be mixed together intimately, a requirement that rules out many high-energy combinations that would start reacting as soon as they came in contact. Hybrids have no such difficulty. Their fuel can be hopped up with a high proportion of high-energy powdered metals or metallic hydrides, but in the absence of an oxidizer, they remain as inert as an auto tire. The oxidizer may be a fiercely reactive fluid such as OF2 (oxygen difluoride), but since it stays in its own tank until needed, it behaves itself. When the two components come...
...radiates unprecedented self-conscious affirmation. Here stands Beckmann in a piercingly direct encounter with himself and with the viewer. In an effort to counterbalance the fluidity of his development, indicated by the amazingly protean variety of his many self-portraits, he takes a stand as absolutely assured, solid, immovable. In the midst of the uncertainty and change which prevails around and within him, he captures forever on canvas the transitory element in himself. Permanence, solidity, self-confidence--to these qualities, so precious and so rare in everyday existence, he give lasting shape...
