  • Patent number: 8226349
    Abstract: A method of using a delta shaped blade as an aircraft propeller, helicopter or autogiro rotor, or wind turbine propeller is presented. The invention combines the delta blade system with the use of torsion bars to achieve desirable control of blade twist. The invention uses blade twist to control the air loading on the craft; hence better control of maneuvering is achieved. The invention also optionally includes adjustable blade roots such that the sweep and aspect ratio of the delta blade is controllably variable. Compared to traditional propeller blade configurations, the invention boasts improved performance and enhanced aeroelastic properties. The invention is a far more efficient system providing economic advantages, higher speeds, and more durable designs.
