High-Angle-of-Attack Translating and Pitching Wings Interacting with Finite Obstacles

Abstract

The project goal is to understand the aerodynamics of flight near finite-sized obstacles, including ground and ceiling features, and through ducts or channels. The application is the design and control of Air Force drones for successful operation in complex environments, such as close to buildings and disaster sites, near forest canopies and rocky ground, and within ducts or caves for smaller craft. This will significantly increase the Air Force’s ability to gather information, conduct search-and-rescue missions, and engage in combat in these environments. When maneuvering near obstacles, the wing may attain high orientation angles, which cause the air to separate and form swirling vortex flows, making the aerodynamics and forces unsteady. Therefore, a range of wing angles and pitching will be examined. The objective is to understand finite-obstacle encounters through approach, interaction and recovery, for which there is little research.
