The mission of Project VOLT Determine the feasibility of using the flow of

atmosphere across the surface of the BalloonSat, flown to 30 kilometers, during accent, to provide power to a BalloonSat.

Mission Overview

Flight Tube will be attached to box with ball bearings, allowing the box to spin

Airflow across the surface of the box and the fins will spin the box

A magnet will be attached to the flight tube, allowing it to spin within the box

The magnet will spin within coils of wire, generating a current in the wire

Design Overview

A GO PRO camera will film the flight A Canon Camera will capture images during

flight Temperature Sensors will record both

internal and external temperature during flight

A humidity sensor will record humidity during flight

A pressure sensor will record pressure during flight

A 3Axis Accelerometer will measure acceleration in the X, Y, and Z axis during flight.

completely intact All components

remained in position

Test Results

Hope to recover data from flight confirming our hypothesis that wind power is not a feasible source of power for BalloonSats

We expect that the amount of power generated will be greatest in the first part of the flight

It will increase to its highest near the top of the troposphere, where average wind speeds are highest

The lower density of the air should make for less force spinning the balloon

All of this data will come in the form of discrete data points of current and voltage

This data will be graphed and compared to the altitude of the BalloonSat

Prediction of Flight Results

Not enough spin to cause the magnet and wire to create voltage

Low amount of spin on the BalloonSat Current sensor does not record properly Fins break off of Satellite during flight
