Title: Winfried M Feifel: Innovator in Aerodynamics
Introduction
Winfried M Feifel is a notable inventor based in Redmond, WA (US). He has made significant contributions to the field of aerodynamics, holding a total of 3 patents. His work primarily focuses on enhancing the performance and efficiency of airfoil designs and hydrofoil vessels.
Latest Patents
One of his latest patents is for an airfoil member that features an upper surface contoured to create lift. The design includes a lower airfoil surface with a forward portion that curves concavely into an expanded convexly curved belly section. This innovative design allows for a primary load-carrying member, such as a spar, to be positioned in the belly section, achieving greater depth without compromising aerodynamic performance. In another embodiment, both the upper and lower surfaces of the airfoil are contoured with the expanded belly portion.
Another significant patent is for a flap flexure retainer and seal designed for hydrofoil vessels. This invention combines a liner retainer and seal for use with fluid foils that have trailing control flaps. The control flaps are hingedly engaged to the trailing end of the foils and can be rotated for control purposes. The design includes segmented flaps that form a series, with keys extending from a driving flap into a keyway in a driven flap, allowing for synchronized rotation. The elastic liner within the keyways protects the metallic surfaces, while the combined seal and retainer inhibit pressure bleed between the flaps, significantly reducing cavitating and separating flow.
