Measuring the Thermal Conductivity of Irradiated Foam-Type Insulation Materials
The development of a flight-qualified nuclear-rocket propulsion system has progressed rapidly during the past three years. Space missions requiring this propulsion system are being evaluated and planned. The reliability and operating characteristics of these systems cannot be assessed, however, without a thorough knowledge of the effects of radiation in combination with other environments on the materials and components making up the systems. Organic materials are particularly vulnerable to radiation and deserve special attention. Insulating materials and insulation systems, because of the importance of their functions, are prime candidates for early assessment.
