Abstract
Supersonic air vehicles require nose radomes that can withstand high temperatures as well as have high RF transmission over wider radio frequency bandwidths. Typically nose radomes are built from solid laminate or monolithic ceramic materials which inherently have a very narrow frequency band over which they are RF transparent. The proposed concept leverages a qualified ceramic matrix composite (CMC) AS-N312 as the outer shell that will withstand the forces and environments. To achieve wider bandwidths, lower dielectric ceramic foam materials are added to the inner surface enabling transmission of a broader range of wavelengths. The proposed designs avoid inclusion of an inner skin that would form a more traditional sandwich structure to prevent significant shear stresses from occurring in the ceramic foams. The program will develop candidate foams, build a prototype radome using all materials consistent with high speed flight profiles, and provide test data on the RF transmission characteristics of candidate layered designs. Affordability is improved because AS-N312 is the lowest cost, qualified structural ceramic material available today, and the processes to achieve other attributes such as erosion protection and EMI filters are also fully developed and cost effective.
