The final design of the group’s AEV can be seen below. It is very similar to the original prototype of the AEV. However, the AEV’s base and wings are now separate from each other. By making the two pieces separate, they could be easily 3D printed with correct dimensions. The most unique addition of the final design was implementing the servo motor onto the arm of the AEV. The servo motor would serve as a braking system. The motor consists of an arm that rotates. When rotated, the arm would hit the track and cause enough friction to stop the AEV.
Above is a complete drawing with basic dimensions of the AEV.
Above is an exploded assembly view of the AEV. The drawing consists of every individual part that was used, along with pathways of where the part would be connected.
Above is the drawing of the base of the AEV. It has two noses placed at each end of the base, which was aimed to make the AEV more aerodynamic. The also has two rectangular cut outs toward each end of the base. This would reduce the weight of the AEV. The Arduino will be placed towards the front of the base and the battery will be placed towards the back of the base. The wings and T crossbar will be placed in the center of the base.
Above is a drawing of the wings for the AEV. Each wing is 3 inches long, which would provide enough space for the propellers to freely rotate. Fillets were placed on the edges of the wings to help increase airflow when the AEV was running on the track.
