    STEALTH WIND ROTOR BEATS RADAR

    Successful research of stealth turbine for radar-sensitive locations
    29 June 2011 (Vestas)

    Vestas, the world leader in providing high-tech wind power systems…has taken a major step forward in solving a critical wind energy challenge: It has successfully tested a full-scale ‘stealth’ rotor on a turbine, paving the way for wind power plants to be located near many military, airport and other radar systems without interfering in their operations…

    "The stealth turbine test…conducted at a UK customer site with technology partner QinetiQ, is part of an ongoing research collaboration that began in 2006. Preliminary test results…showed that a Vestas V90 turbine with stealth rotor achieved a targeted reduction in radar cross-section of approximately 99 percent, or 20 decibels, compared with standard turbines…"

    "With an estimated 20 gigawatts of wind power capacity currently blocked worldwide by concerns about radar interference, Vestas’ stealth turbine research has validated a potentially important addition to the operational, technical and political mitigation tools available today…

    "The stealth turbine solution uses a portfolio of radar absorbing materials that are integrated into the current manufacturing processes for turbine components and can be designed to operate at aviation and maritime frequencies. These modifications do not affect the performance or appearance of the turbines, which meet current visual standards…The full-scale test… follows more than five years of research…"
