...last week's Washington meeting of the American Rocket Society, a 90-ft. Titan missile stood outside the building; often discussed at the meeting were other liquid-fuel rockets. These types are dominant in the U.S. and probably in Russia. Their great advantage: they work. But also discussed at the meeting was the progress being made in solid-fuel rockets...
...fuels-a low-melting alloy of U-233 and bismuth, a solution of uranyl sulfate, and others. But AEC soon discovered that the program was leading only to prohibitively expensive means of obtaining competitive electrical energy, and last week it announced a shift in emphasis: funds for the Brookhaven liquid-fuel project and similar ones elsewhere have been largely diverted to AEC's Oak Ridge laboratory for development of a thermal breeder reactor that will make uranium 233 from thorium, the first natural raw material other than uranium to be used as a producer of peaceful atomic energy...
Thor ICBM, and the second stage, a 19-ft. liquid-fuel job built by Lockheed, apparently worked well. Watchers assumed that the bird, which consisted of the 1,300-lb. second stage with a 40-lb. instrument payload, had gone into orbit over the South Pacific...
...Solid-fuel rockets are the dream weapons of military rocketeers. They have no pumps or valves to go wrong and are always ready to fire. Their big trouble is that they are harder to control than liquid-fuel rockets, whose small combustion chambers, fed by flexible pipes, can be mounted on gimbals. When a liquid-fuel rocket takes off, it can switch its gas jet from side to side, correcting any tendency to veer off course. But solid-fuel rockets have no separate combustion chamber, only a nozzle to form the gases into a high-speed jet. Usually the nozzle...
...Pipe. Another system is to mount the nozzle at the end of a large, flexible coupling so it can switch from side to side like the combustion chamber of a liquid-fuel rocket. This is extremely difficult because the flexible pipe must carry the giant flow of hot, high-speed, high-pressure gas without leaking or burning out. But Ritchey implied that it can be done in an efficient way that causes little drag loss...
