Mission Overview





Send a BalloonSat to an altitude near 30 kilometers
Try generating power from the angular velocity of the
BalloonSat
Objectives Be ready to launch on December 1st, 2012
 Record pictures and video of the entire flight
 Measure variables of the surrounding environment
 Confirm the feasibility of wind power on BalloonSats
Will contribute to our understanding of how we can make
power systems on BalloonSat’s in the future
Power is often the downfall of many experiments operating in
conditions similar to ours
Mission Overview Cont.






Contribute to the length of experiments we can perform in
the upper atmosphere
Over the course of the flight we expect to see a large
difference in the amount of power generated over altitude
We also expect to find that the initial turbulence of the
balloon after takeoff will decrease over time
We plan to maximize the amount of energy that can be
generated throughout the troposphere
By comparing our data to how much was consumed during
flight, we can discover how feasible it is to power a
BalloonSat with angular velocity
If successful could be used in subsequent flights of balloons
with different designs to supply a longer lasting source of
power
Design


Structure:
 Foam core to create the outer cube, as well as all interior
divisions needed
 Foam core will be used to support the copper wire coils used in
the experimental generator
 Tape, Velcro, and glue will be used to bind the structure together
and interior components
 Will be attached to the flight string through a PVC pipe through
the center cube
Experimental Power Generation:
 Ceramic bearings will attach the PVC pipe, around the string, to
the BalloonSat
 Allow it to rotate independently of the rope
 Attached to the PVC pipe on the inside will be magnets
 The magnet poles will be perpendicular to the length of the tube
 Copper wire will be coiled parallel to the length of the tube
 These coils will connect to a voltage sensor to measure current
produced

Environmental Sensing:
 Measure both the internal and external temperature of the Sat
using thermometers
 Also use a three-axis accelerometer to measure the movement
throughout its journey
 A pressure sensor will be used to track the pressure during flight
and a humidity sensor to track humidity levels
 All sensors will interface into an Arduino Uno and will be
recorded on a 2GB Micro-SD card
 An active heater system will be used to maintain a temperature
above -10 degrees Celsius inside
Imaging:
 Canon A570IS Digital Camera will be used to capture lower
quality images
 A GOPRO HERO HD video camera will be used to capture high
definition video during the flight
 Images will be recorded on 32G Micro-SD card
Design Cont.
Testing:
 Tests will include drop tests, cooler tests, subsystems tests, functional
tests, whip tests, and mission simulation tests
 Drop tests with mass models will allow us to determine the structural
integrity during impacts
 Whip tests allow us to test structural integrity at speeds over Mach 1
 Cooler test using dry ice allow us to test in a subzero environment
 Subsystems will be tested individually to identify errors
 Special Features:
 Propeller Design on the exterior of our box to enhance the angular
velocity during ascent
 Data:
 Recorded by the sensors onto a 2G Micro-SD card during flight
 During the drop and whip tests data will be obtained visually
 All other tests data will be obtained either by ringing with a voltmeter or
by connected to our computers
