New environment-free alternator developed using water coolant

An alternator, said to be the first successful vaporization-cooled, environment-free alternator in the industry, maintains satisfactory cooling while operating in extreme conditions of temperature and altitude. Developed in connection with North American Aviation´s guided missile research program, the new alternator is the result of Jack and Heintz, Inc., research on power units that offer environment-free operation and impose a minimum penalty on the aircraft.
