Abstract: Controllers for a pitch and a stall regulated horizontal axial flow, variable-speed tidal stream turbine are developed, and a performance comparison is carried out. Below rated flow speed, ...

Abstract: Wind energy has the highest development rates of renewables. The increasing complexity of wind turbine (WT) systems requires careful analysis and design with thorough testing and ...

Which leads to by far the most interesting innovation on this aircraft in my eyes; if the props are flat, does that mean SiFly runs variable-pitch blades ... to wait for propeller RPM to catch ...

The aircraft, which is certified as an light sport aircraft (LSA) glider, is equipped with a variable pitch propeller that can be feathered for gliding with the engine shut down. This Sinus FLEX ...
