Abstract:

A tangent-ogive and three compound-ogive radomes are examined for use of one of them as a substitute structure in analysis of Von Karman radome thermal stresses. A tricentric ogive-cone radome is chosen as the substitute, because it provides a highly satisfactory representation of the Von Karman profile both in regard to approximate duplication of cross-sectional radii and coordinate angles for nearly all values of the spanwise variable. The introduction of a substitute structure is made necessary by the absence of stress solutions for the Von Karman profile type of structure in current and past technical literature, but a theoretical solution for ogive shapes is available. Also, the temperature distribution obtained in previous investigations on the Von Karman test radome is herein successfully imposed on the substitute structure with results that agree within two percent of those computed from formulas that were obtained in the earlier studies.
