Pranay’s sketch used a very basic design. It would use the motors and propellers to push air behind the AEV, propelling it forward. It has a simple, jet-like design that would help keep its weight low. This design would likely come into trouble when attempting to reverse, while it will still work, the air flow would be partially blocked, and more air resistance would be met with the bulkier side heading forward. Pranay’s design used the standard arm, wheels, and plastic base provided, along with a thick, stiff paper to form the base of the design. Pranay’s design was 9 in long, 6 in wide, and 6.5 in high. It would weigh approximately .65 lbs. The Bill of Materials is Table 3 in the appendix, and the design has a final approximate cost of $165630.
Riley’s design used a pirate ship like design. A sail was placed in between the railing and the base of the AEV. A single motor was placed behind the sail to power propellers and push the sail forward. This design would work well in theory for moving the AEV forward, but would need some major redesign to reverse efficiently. The sail would only cause drag if the motor was reversed, causing high power needs to order to more the AEV in reverse. Riley’s design used the standard arm, wheels, and plastic base provided. A thick paper is used to form the shape of the hull, and standard computer paper is currently being used as the sail. Riley’s design is 6 in long, 3 in wide, and 5.5 in tall. It would weigh approximately .55 lbs. The Bill of Materials is Table 4 in the appendix, and the design had a final approximate cost of $163630.
Jeremy’s design used a sail system like Riley’s, but with 2 sails extending down under the base of the AEV. A single motor with a propeller is in between the sails, attached to a servo motor. The servo would rotate the motor to change which sail is being used for acceleration. This gave the benefit of similar speeds in the forward and reverse motions. This could also cause large problems, with an extra sail that wasn’t in use, this increased the amount of drag on the AEV and would cause it more overall power to move. Jeremy’s design used the arm, wheels, and plastic base given, along with paper as a sail. Jeremy’s design is 8 in long, 5 in wide, and 12 in high. It would weigh approximately .5 lbs. The Bill of Materials is Table 5 in the appendix, and the design had a final approximate cost of $149880.
Han’s design uses a simple design with two motors and propellers as the main source of propulsion. It is similar to Pranay’s sketch, although it put the motors more central. This may lower the speed while going in the forward direction, but may help to alleviate someone of the slowdown that would be experienced in the reverse. Han’s design used the standard arm, wheels, and plastic base provided. Along with those, it has 4 total sets of motor propeller combos. Han’s design was 7 in long, 7 in wide, and 6 in high. It would weigh approximately .48 lbs. The Bill of Materials is Table 6 in the appendix, and the design had final approximate cost of $150780.
