Low Cost, High-Temperature Conformal Antennas

Abstract

Due to a critical need for the development of high-temperature conformal antennas to enable hypersonic flight (in excess of MACH 4), Alliant Techsystems (ATK) is evaluating materials for forming these complex shapes. The objective of this project was to develop a conformal antenna solution to meet the demands of aerodynamic heating. The project focused on the development of two formulations of HotBlox with ideal dielectric properties of 2.0 and 4.0 and the development of a process for molding the parts to near net shape. Most importantly, one component needed to have a dielectric constant twice that of the other component. The National Center for Defense Manufacturing and Machining (NCDMM) provided program management and lessons learned from working with American Technical Coatings (ATC) on earlier HotBlox projects that recommended further application of this material.
