> A small private plane collided with a two-engine Scandia transport flown by Brazil's Vasp Airlines in the crowded air corridor between Rio de Janeiro and São Paulo. All 27 aboard both planes were killed, their bodies strewn along more than two miles of rugged mountain...
The 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...
White-Hot Metal. The most striking Middletown project is SNAP-50, a lightweight nuclear-power reactor designed to operate in space. Incorporating technical know-how gained on the airplane-engine project, this SNAP (for Systems for Nuclear Auxiliary Power) contains liquid lithium and gaseous potassium, tricky fluids that would drive...
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...
The 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...
