Foam insulation nickel-plated with one less step. Changing tie-in layer from plasma-sprayed nickel to plasma-sprayed copper eliminates intermediate copper electroplating step previously required.
This paper is the third in a series discussing space station-shuttle power systems. The power requirements of the orbiter and a tradeoff study of several possible power system concepts are presented. The power sources considered are fuel cells, solar array/battery, radioisotope Brayton, and cryogenic fueled turboalternators. A fuel cell power source is chosen as the best candidate for the orbiter power system. A baseline power system is defined using four fuel cells, secondary batteries, primary emergency batteries, and constant speed drive-alternator units for ferrying power. A weight and cost summary is included.
