Materials Problems in Airborne Radomes Designed for High Speeds

Description
-
The task of choosing materials for radomes to be flown at supersonic speeds is a difficult one. Before the design of a radome can be started, it is necessary that the designer have on hand adequate data concerning electrical and mechanical requirements. There is presently no simple line of reasoning by which he can proceed directly from this information to the selection of an appropriate material. The complexity of the problem is indicated by Figure 1. Because of the interrelation of the many factors involved, selection of an adequate material requires a careful balancing of a number of considerations and usually results in compromises in the degree to which each requirement is met. The choice is made more difficult by the lack of data on the performance of most materials under the conditions expected in flight.
It is the purpose of this paper to point out certain lines of inquiry which may be helpful in the selection of materials or in the development of new materials. It will not be possible in the time allotted for this paper to treat the problems involved in a comprehensive manner. Instead, after a brief discussion of some general considerations, a description will be given of experimental work being carried on at Hughes Aircraft Company with the aim of filling gaps in the existing information concerning properties of materials. Much of the work reported deals with the effects of aerodynamic heating, currently one of the important factors in radome design and material selection. Discussion of this topic will point out some of the interrelationships suggested by Figure I.
