SPIRIT of the KoalaProject VOLTCritical Design ReviewAnthony Anglin, Colin Harkins, Dylan Cooper, Thomas Jefferies, Starteya Pais, Joao Mansur, Andrew Trujillo, Dustin Fishelman
Mission Overview Prove the feasibility of using the flow of atmosphere across
the surface of the BalloonSat to generate current Expect to discover that using magnets and the spin of the
satellite will generate current We predict variation in the levels of current that will be
generated We are conducting this mission to determine the feasibility of
using wind to power experiments in future BalloonSats
Flow Down
Flow Down Part 2
Flow Down Part 3
Design Overview Bearings will allow BalloonSat to rotate independently of the
flight tube Magnets attached to the flight tube will rotate within a coil of
wire, generating electric current Current and voltage generated will be measured and
recorded Fins attached to the outside of the cube will be used to
increase the amount of air flow
Ordered Parts Ordered parts include:
Neodymium magnets Sealed, ceramic, stainless steel ball bearings Current and voltage sensor
Order Status: Magnets: Ordered, received Bearings: Ordered, received Current Sensor: Ordered, received

Proposal Requirements Our BalloonSat will generate electricity, powered by the rotation of
the BallonSat Using magnets rotating through coils of wire
A GO PRO video camera will be used to image the flight Attached inside of cube opposite of the camera
BalloonSat will be recovered GPS and the string will keep them all attached and able to be discovered
Flight String will attach to the BalloonSat through a PVC pipe Must be tied very tightly to ensure the pipe does not spin, only the cube
Temperature will remain above -10 degrees Celsius Through dry ice testing and multiple layers of insulation
Weight will not exceed 1125 grams Our weight budget shows we will not exceed
A three axis accelerometer will be used to measure acceleration during the flight Shown in our block diagram, will be attached to Arduino
Proposal Requirements 2 Design will allow for an Arduino UNO and related
components Shown in our block diagram and drawings
External temperatures will be measured Shown in block diagrams
Canon A570IS will be used to image the environment Placed facing outwards, opposite side of GO Pro
An active heater system will be used to maintain interior temperature Shown in our block diagram
A visual indicator on the exterior of the BalloonSat will allow SOK to confirm that the payload ready is for launch Will use an LED light attached to the inside to indicate launch
preparedness
Test Plan Tests will include drop tests, cooler tests, subsystems tests,
functional tests, whip tests, and mission simulation tests Will experiment with different fin types to conclude which one
will create the most drag and spin Mission Simulation will include spinning the cube by hand,
and taking it to the wind tunnel for testing Already have done drop at DLC and some whip tests Future tests will include dry ice cooling, and more whip tests
Test Schedule October 7th – Drop Test October 21st – Spin Test October 28th – Sensor Testing (Pressure, humidity,
accelerator, temperature) November 4th – Functional Test (Generator testing) November 11th – Subsystem Test (External and internal) November 18th – Cooler Testing November 25th – Mission Simulation Test
First Draft Thoughts Expect to see spin created by the fins and the rotation on the
BalloonSat From this spin there will be evidence of current and voltage
created Will show that we can supply voltage for most of the
experiment, but not entirely Results will prove that using the rotation is a sufficient
method of running an experiment

Biggest Worries Will not generate current Magnets will not properly rotate through coils Not enough spin during flight Fins will break off
