DemoSat V: CSU DemoSat Team Colorado State University Abby Wilbourn, Tyler Faucett, Paul Scholz, and Michael Sombers July 28, 2010

2 Mission Statement & Goals: -The mission of the CSU DemoSat Payload is to determine elevations for maximum alternative energy (solar and wind energy) collection. -Objectively measure solar and wind output at increasing elevations -Measure pressure, temperature and acceleration to determine other environmental factors involved in energy collection -Achieve all goals while remaining under 1.5kg in weight and spending less than $1000

3 Benefits to NASA: -This payload is an affordable, reusable, lightweight way for anyone who want quick access to data to find the optimum altitude for renewable energy collection, as well as general atmospheric conditions at these altitudes. -Future revision to this payload could allow for real time telemetry for quicker access to the data.

9 Expected Results:  Payload is launched with outside temp of 20 C  Minimum temp will probably reach -60 C at 12,500 km  Our solar efficiency gain relationship from testing was  Our solar efficiency gain relationship from testing was y = ln(x) From that, the increase in solar efficiency at this altitude should roughly be 19%

10 Expected Results:  Solar Efficiency should also increase as altitude increases or pressure decreases  Increase will be due to less atmospheric gas to scatter solar energy as well as the disappearance of the clouds  This increase due to the less dense atmosphere will be slow, but we expect a large increase above 15 km when the clouds are gone.

11 Expected Results:  Wind speed is expected to vary drastically as a function of altitude  The max we may see on this flight may happen at an altitude of 10 km or right at the Tropopause

12 Level of Readiness: Bench test data recorded as Voltages

13 Level of Readiness: Bench test: Payload sitting outside mid day for 3 hours
