Ulrich Hütter

Ulrich Hutter was an Austrian-born aerodynamicist and wind turbine engineer whose research at the Technical University of Stuttgart in Germany during the 1950s and 1960s established the aerodynamic and structural principles behind the modern three-bladed, pitch-controlled, lightweight wind turbine. His prototype designs, including the influential Hutter-Allgaier W-34 built in the early 1950s, used slender fiberglass composite blades and pitch control methods that later became standard across the wind power industry, and his theoretical work on blade aerodynamics and turbine loading directly informed the generation of large-scale wind turbine designers who followed him from the 1970s onward.
