Abstract

The Illini Air Shuttle RSO is working to design an Electric Vertical Take-off and Landing (eVTOL) Aircraft. One part of the project is to design a subscale version of the eVTOL aircraft. The subscale model project has two main objectives. The first one is to design and built a functioning power train so that the propulsion system can provide sufficient thrust for the subscale model to take-off vertically and hover which includes self-stabilization. This power train includes 12 BLDC motors and a self-stabilization system. The second objective is to design the body and wing for the subscale model so that it can also fly horizontally, taking advantage of the wing to provide lift force to counter the weight of the subscale model. Furthermore, from the previously built power train, I must iterate the power train to include a mechanism for the subscale model to transition from taking off vertically to flying horizontally. The result of the project is that the subscale model with 12 BLDC motors were able to successfully take-off vertically and hover at about 4 meters for at least 20 seconds. Furthermore, because of the self-stabilization system within the flight controller’s firmware, the drone was able to self-stabilize using the data from its accelerometer and driving the BLDC motors appropriately through the Electronic Speed Controllers (ESCs). Plus, I successfully create a theoretical design for the body and chassis of the 2-full wing subscale model that can support the power train integration and can provide sufficient lift when flying horizontally, based on the constraint of both my fixed and chosen parameters. Finally, I was able to theoretically design the mechanism for transitioning between vertical take-off and horizontal flight. 4 servos are required to turn the 12 motors for the horizontal flight with the help of gears and axels.
