The Effect of Carbon Fibre Body Panels on Aircraft RCS
A simple case study at 50MHz to demonstrate the effect on aircraft RCS of using carbon fibre body panels, rather than metallic body panels.
- Compute the monostatic RCS of an F5 fighter aircraft.
- Demonstrate the differences in RCS between a fully metallic airframe and an airframe where the majority of body panels are made from carbon fibre.
- Single layer of carbon fibre and used in construction (few metallic parts remain), with fibre alignment direction and metallic areas as indicated here.
- Carbon fibres are bonded with epoxy, resulting in layers with the following electromagnetic properties.
|Conductivity (S/m) ||Relative permittivity
