UFO Generation #3

Schedule

by Shamir Mohideen (Project Manager)   We were able to completed most of out assignments on time however after completion we had some issues such as the 30A ESC stopped functioning correctly which caused some set backs. We did not have enough time to complete the bluetooth controller for the quadcopter however we did establish […]

Battery

By Anthony Jackson (Power Engineer) Battery The maximum current draw of each motor is 27A. The overall maximum current draw of the 4 motors will be 108A. Using the following equations we are able to calculate the maximum current a battery can supply Max current = capacity * C-Rating Flight time at maximum amperage would […]

ESC Current Draw Test

By: Nathan Winter (System Test Engineer) Introduction We calculated the current draw of our EDFs so we can get a better estimate of our overall power budget. Procedure The circuit is very simple. We used a multiwii 328P to control the signal to the ESC. We placed a multimeter in series with the positive ends […]

Electric Ducted Fans

by Nathan Winter An electric ducted fan (EDF), is a type of shrouded-rotor configuration used in Micro Air Vehicles (MAVs) to increase safety and performance when compared to open-rotor configurations. The duct increases safety by creating an enclosure for the fan, which decreases damage to the propellers during a mishap. The ducts also reduce the […]

EDF Thrust Test

By: Nathan Winter (System Test Engineer) The thrust for each EDF was calculated by building a simple test platform that has an EDF mounted to it, facing downward. The base of our platform is flat for an equal weight distribution on a scale. We put the platform and EDF on a scale and zeroed the […]
