Feasibility Study of an Axially-Stacked, Subsonic Propeller System

With the aerospace industry pushing for an increased production and application of unmanned aerial vehicles (UAVs), humans will increasingly become exposed to noise pollution emanating from above. Fortunately, electric motors have and will continue to gain an ever-prominent role in the power plant of small, to mid-sized air vehicles, thus reducing the levels of acoustic exposure due to aircraft. However, one consequence of this electric motor emphasis is that the noise generated from an electric motor-powered UAV may become dominated by the propeller’s acoustics. In many cases, this propeller is selected off-the-shelf and only given consideration late in the design process. In an effort to reduce acoustic emission of future UAVs, this thesis explores a unique multi-stage propeller configuration, which may be applied to a vehicle post-design. It is my intention to explore the feasibility of this unique propeller configuration with aerodynamic and acoustic analysis.
