RCS Analysis of a Configurable Mock-Up Cavity With Blade Motion Capability

The scattering behavior and simulation of cavities are still being studied by several research groups. In this paper, a simplified jet-engine model has been manufactured and measured under different configurations, such as straight or curved blades, different fixed blades position, and free motion capability at adjustable speed. These measurements can be used to analyze the response of cavities as well as radar cross-section reference data for validating existing and future prediction codes.
