Abstract
Investigations were made of materials and methods for mechanically transmitting deflections from a structure under radiant heating to a transducer at room temperature. Transparent fused quartz rods were evaluated for expansion and thermal shock resistance. Rod growth was measured for such rods under several heating rates, with various exposed rod lengths and at temperatures up to 2000 F. The growth enabled fairly accurate monitoring of static and cyclic displacements of a plate to which a transducer was connected through the quartz rod. High purity recrystallized alumina rods were evaluated for expansion and thermal shock resistance. Rod growth was also measured under several heating rates for a limited exposed length and at temperatures approaching 3000 F. The measured growths were considerably greater than those experienced by the quartz rods but not by a factor equivalent to the ratio of their thermal expansions. A successful means for attaching such rods to aluminum structures capable of following static and cyclic displacements were developed.
