Thermal Stress Limitations of Alumina and Pyroceram 9606 A-Sandwich Radomes
Abstract
A study was made to define the flight limitations of supersonic missiles which are imposed by thermal stress failure of ceramic A-sandwich radome structures. The investigation verified the accuracy of an analytical model for determining thermal stresses in sandwich materials, and then used this model to define the thermal stress limits of alumina (Al2O3) and Pyroceram 9606 A-sandwich radomes when flown on supersonic trajectories. Velocity versus time plots of a number of A-sandwich wall configurations are presented, each showing the time of thermal stress failure for a particular trajectory. These give a representative picture of the flight limitations of alumina and Pyroceram 9606 A-sandwich radomes.
