Abstract:

Functions of approximation to particular solutions that occur in the ogival radome thermal-stress problem are presented. It was found by numerical comparisons with the generating differential equations that the approximate closed-form solutions display an error range of no more than plus or minus one- half percent. The solutions were derived to gain two major advantages first, a reduction of analytical complexity lessens the chance of computational error and, second, certain unwieldiness in numerical work is reduced or eliminated. Computer results for repeated future application in the evaluation of thermal stresses in blunt and pointed radomes of compound-ogive configuration are tabulated.
