In this thesis, we present the design and analysis of a distributed, electric, ducted propeller powerplant. In the introduction, we present our goals, which is followed by an overview of the theoretical foundations of sailplane propulsion, where we also include the description of Penaud diagram and derive the equation of induced velocity due to propulsion. Next, we design the support structure of the system and design and describe the production of propellers. In the empirical part, we make a test stand and then test the drag of the system on the car at the flight speed. In the second test, we only test the thrust of one propulsion unit and not of the entire system. Based on the measured thrust of the second test, we conclude that a sailplane with the designed system could climb.
