Title: Bruce J Holmes: Innovator in Aerodynamics
Introduction
Bruce J Holmes is a notable inventor based in Newport News, VA (US). He has made significant contributions to the field of aerodynamics, holding a total of 4 patents. His innovative work focuses on improving the performance characteristics of lifting surfaces.
Latest Patents
Among his latest patents, one notable invention is the "Serrated trailing edges for improving lift and drag characteristics." This patent describes an improvement in the lift and drag characteristics of a lifting surface by attaching a serrated panel to its trailing edge. The serrations may have a saw-tooth configuration, with a 60-degree included angle between adjacent serrations. Additionally, the serrations can vary in shape and size over the span-wise length of the lifting surface, and they may be positioned at fixed or adjustable deflections relative to the chord of the lifting surface.
Another significant patent is the "Method for laminar boundary layer transition visualization in flight." This invention discloses a method for visualizing laminar to turbulent boundary layer transition, shock location, and laminar separation bubbles around a test surface. A liquid crystal coating is formulated using an unencapsulated liquid crystal that operates within a temperature bandwidth compatible with the environment around the test surface. The coating is applied to a pre-treated surface, which is subjected to a liquid or gas flow, resulting in a color change in response to differences in relative shear stress within the boundary layer.
