To escape into outer space, Lewis pointed out, requires an initial speed of 6.95 miles a second (25,020 m.p.h.). This requirement cannot be dodged by running the rocket motor slowly over a long period; that would only waste energy by forcing the ship to carry heavy fuel to a...
Dr. Tsien's rocket liner would be 78.9 ft. long and 8.86 ft. in diameter, with a loaded weight of 96,500 Ibs. It would have small wings and a ramjet as well as a rocket motor. Its maximum speed, 9,140 m.p.h., would carry the ship 1,200...
To reach "escape velocity," the space ship's fuel must be used as economically as possible, and the efficiency of a rocket motor depends on the speed of the exhaust gases. Lewis calculated that a space ship carrying half its total weight in fuel would have to shoot out...
Since the speed of the exhaust gases is proportionate to the temperature in the combustion chamber, Lewis next calculated what temperature such a rocket's materials would have to stand. The figure came out about 506,000° F., which is about 80 times more than enough to melt...
Experts called it the biggest atomic news since the end of World War II. The Atomic Energy Commission revealed last week that it is now considered practical to build a nuclear reactor which will "breed" more atomic fuel than it consumes.
