An experimental dataset is presented of propeller performance in static condition and at low subsonic airspeeds for various angles attack up to 90 deg. Numerical investigation through a Reynolds-averaged Navier–Stokes computational fluid dynamics model revealed the mechanisms behind changes with advance ratio, angle attack, configuration changes. The was found be free major errors very suitable...

The goal of this work is to develop low order dynamical systems models for the unsteady aerodynamic forces on small wings and to better understand the physical characteristics of unsteady laminar separation. Reduced order models for a fixed, high angle of attack flat plate are obtained through Galerkin projection of the governing Navier-Stokes equations onto POD modes. Projected models are comp...

The Wright brothers followed their invention of the first practical airplane (1903) with a second epochal invention, the angle of attack sensor and aircraft stabilizer (1908). Both inventions were patented and details of each are contained in the respective patents for these two aeronautical advances. This paper emphasizes how the angle of attack sensor actuated an "automatic stabilizer." This ...
