Objectives Previous DTI-funded research clearly showed that, although blades cause the main Doppler problem for Air Traffic control (ATC) radars, the nacelle and tower still contribute to false plots. It is thus necessary to control all radar cross section (RCS) contributions, and stealth materials offer a viable method to achieve this. RCS modelling of turbines treated with radar absorbent material (RAM) is encouraging, but stakeholders, whether they be objectors or developers, requireevidence that thepredicted benefits of RCS control are real and achievable before accepting the technology. The aim of the project is to demonstrate whole-turbine RCS control, using RAM solutions that are integrated within the composite blades and nacelles, and as claddings for towers. The project begins with an assessment of various levels of RAM treatment for a Vestas turbine and demonstration of RCS reduction applied to a blade section. A carbon-containing composite RAM blade will be be produced and mechanically tested. Finally, a complete low-RCS wind turbine (carbon blades, nacelle, tower) will be designed, produced, installed and evaluated.
