  • Adaptive control ducted compound wind turbine
    Patent number: 8829706
    Abstract: A high efficiency, adaptive control, compound ducted wind turbine capable of providing higher efficiency in energy extraction from a fluid. Performance of efficiency expressed as coefficient of performance (Cp) in accordance with the Lanchester-Betz-Joukowski limits is sustainable and significantly higher than an un-ducted, mono-propeller wind turbine of comparable diameter. Also an active circulation control wing technology is disclosed for increasing efficiency and performance and which is applicable to both wind and water turbines.
