...Ericsson, Sweden's aggressive manufacturer of telephone equipment, will be responsible for the Viggen's radar, Standard Radio (a Swedish subsidiary of International Telephone and Telegraph) will make the operations control system, and Svenska Flygmotor will build the souped-up JT8D engine under license from Pratt & Whitney. Slated to reach quantity production in 1969-70, Viggen is expected to keep 10,000 Swedish workmen busy for several years and to pour at least $600 million into the coffers of Swedish industry...
...project for which the Middletown, Conn., plant was first built has been abandoned; U.S. authorities no longer feel driven to solve the enormously difficult design problems of a nuclear-powered aircraft. But the Pratt & Whitney engineers who sweated over the complexities of the atom plane's engine are still determined to get some sort of nuclear reactor aloft. They are working for AEC now, and last week the commission allowed them to give a glimpse of their top-secret labs...
Radiation Cooling. Pratt & Whitney chose to work with these unpleasant fluids because building a nuclear engine for space requires a solution for one overriding problem: how to get rid of heat from the condenser. There is no air to cool it by convection; the only cooling comes from radiation, which increases sharply with temperature. If the working fluid were steam, an enormous condenser would be needed to radiate its low-grade heat. The lithium-potassium combination runs so hot that a fairly small condenser does...
...strange fluids demanded new alloys to contain them and new kinds of pumps and valves to move them around. Whole technologies had to be developed to make them behave properly. Pratt & Whitney scientists are confident that SNAP-50 will be well tested by 1965. When it finally takes to space, it will find plenty of important work: providing electricity for long-distance radar and communication, working the spacecraft's instruments and internal machinery, running an ion propulsion engine to change course while cruising through deep space...
...happens, we do not particularly admire Sunday but extended ourselves to give it a fair showing; your reviewer might occasionally try being equally fair. Brattle Theatre (Mrs. John W. Pratt...
