Many a thoughtful Army airman has lately been disturbed by reports that Britain, whose heavily armed and armored pursuit planes are the world's most formidable, is no longer satisfied with its liquid-cooled Rolls-Royce Merlin engine. U. S. airmen found the report disturbing because the Army Air Corps has gone in up to its ears for a similar engine of similar horsepower -the 1,090-h.p., liquid-cooled Allison...
...Allison and Merlin should prove to be out-of-date, the Air Corps will have a lot of explaining, a lot of design switching to do. One possibility is that liquid-cooled engine manufacturers may have to switch over to manufacture of the new Rolls-Royce, with all the headaches that retooling and new airplane design would bring with it. Another is that Allison, whose production is now only 350 engines a month (with a schedule of 1,000 by next Nov. 1), may perfect the 2,000-h.p.-plus 24-cylinder engine now in its research division...
Helium is the hardest of all gases to liquefy. The standard method involves liquid hydrogen, which is unstable and highly explosive. Kapitza's method not only did away with liquid hydrogen, but. cut the cost of making a quart from $50 to $5, the time from 24 hours to two hours or less. In the neighborhood of absolute zero, ordinary lubricants freeze hard as iron and Kapitza's problem was to find a lubricant for his compressor. He solved the problem by allowing a little helium vapor to squeeze through the piston clearance, so that the helium itself...
...which showed valves in impossible places and other aberrations. Nevertheless Dr. Lane persevered, correcting the mistakes in the sketches by hunch and logic as he went along. It took him three years, cost $5,000. Last week he announced that he had successfully completed a Kapitza liquefier, was making liquid helium for low-temperature research quickly and safely, and at a cost of $5 a quart. It is the only Kapitza liquefier in the Western Hemisphere...
...industry expanded, but not enough. Soon outsiders were creeping in-with no better results. G. M. went painfully into chicken-feed production with its liquid-cooled Allison. Packard bravely took the $125,000,000 British Rolls-Royce order that Henry Ford turned down. In November, Ford himself, who had earlier talked of 1,000 planes a day, took a $122,000,000 order for Pratt & Whitney Double Wasps. His engineers went to Hartford to find out how to make them...
