Nuclear-Powered Flight Chapter 6: High Temperature Materials
Abstract
In earlier chapters, pile surface temperatures ranging from about 2000 deg K (1725 deg C) to 3000 deg K (2725 deg C) have been considered for various vehicles. Since there must be a temperature drop in the pile to bring the energy to the gas-solid interface, it is clear that we are considering a range in which customary ceramics have little strength. In the absence of softening and spalling data for very pure graphite and beryllia we cannot specify the temperatures which must be chosen for nuclear-powered rockets, ram-jets and turbojets. Therefore results for a range of temperatures have been given, wherever it seemed useful. However, a few data can be presented to indicate possibilities and to guide structural studies. We consider in succession the following topics: high-melting elements and compounds, piles, control rods, and protection of an atomic warhead against neutrons.
