Abstract

A special purpose radar absorption structure (RAS) has been developed using fiber-reinforced composites with excellent mechanical and electrical properties. The RAS is an element made up of complex structure and materials used in stealth technology. Frequency Selective Surface (FSS) is one of the most representative form of RAS. In this study, we investigated the possibility of active FSS with microchannel structure which can be activated on military aircraft radome. The micro channel is arranged in parallel inside of the radome and can regulate the flow of liquid inside to change the state of the FSS. The micro channel inside the radome and the stacking sequence and fiber orientation of the composite reinforcing the surface of the will affect the structural stability of the radome. We analyzed the structural stability of the radome by using the finite element analysis to simulate the inertia force during highly maneuverable flight situation. In addition, the designed FSS has confirmed that it is "transparent" electronically in the target X-band frequency area.
