Abstract
As interest rises in electric aircraft, efficient electric propulsion is necessary. In this thesis, propeller systems are examined by means of numerical fluid simulations. Parametric variations in basic propeller design for coaxial systems are assessed: inter-propeller spacing, efficiency curve for upper propeller outflow, and lower propeller pitch for thrust- , rpm-, and torque-matching between propellers. A novel aerial vehicle driven by propellers is also modeled and simulated to assess rotor-body interaction effects. Ideal propeller geometric considerations for each case are identified and compared, and causes of detrimental rotor-body effects are identified. Computational results and flow field visualizations for velocity and pressure are presented.
