A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...
WASHINGTON, January 18, 2022 -- Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise ...
Researchers developed an efficient hydraulic-airfoil optimization framework that improved the lift-to-drag ratio of a ...
A combined CFD, wind tunnel and neural network analysis shows trailing-edge serrations raise stall angles on NACA 0012 ...
“Zero-thickness” designs of airfoils to minimize drag or maximize lift. Evolutionary algorithms have shown that designs which have the least drag have a strongly corrugated shape (top), while those ...
Natural laminar flow is a known means of reducing aircraft drag and energy consumption, but its practical implementation is difficult on commercial airliners that cruise at transonic speeds and ...
Some of NL Ventures (Turbine Airfoil Designs) key Resource Conservation and Recovery Act corrective action documents, reports and photographs are accessible online: Corrective Action Statement of ...
