Abstract
A turbine with a basic system of a triangular structure (14) utilizing both lift and drag aerodynamic forces produced by fluid flow energy. The entire triangular structure (14) could either yaw to always face the wind direction (W) or stay in a fixed position. The system (10) uses airfoil blades (12) shaped like an airplane wing, traveling linearly on travel wheels (22) riding on travel tracks (50, 52, 54). While traveling up, the wings are powered by a positive lift force and drag force while using negative lift force and drag force when traveling downward. All wings (12) are connected by a segmented chain (16) which transfers the kinetic power of wheeled wing carriages (18) directly to multiple generators (26), requiring no gears.
