FUNCTIONALIZATION OF PYROCERAM 9606 TEST DATA FOR RADOME THERMAL-STRESS ANALYSIS.

Abstract

For the thermal-stress analysis of radomes built of Pyroceram 9606, the experimentally determined material properties and thermal expansion are studied and expressed as functions of the temperature. The data reduction methods are described in the text and appendix. They were generally based on minimization of the squared error function. In a few cases, the method of equalizing the maximum positive and negative percentage errors was employed. Different regression formulas for different uses are given, according to the degree of accuracy that the analyst elects to maintain. Overall, the derived functions represent the test points within 0.3 to 3 percent approximately, depending on which expression is selected for a particular application. (Author)
