UA ASCEND!Spring 2014

The Team

• Amanda Urquiza• Eric Moser• Andrew Siemens• Ryan Stelzer• Alex Yudkovitz

Fall Launch Recap

• Test efficiency of solar panels at high altitudes• Hypothesis: Solar panels would generate more power at

higher altitudes• Results:• More voltage generated at higher altitudes• Accelerometer failed

Spring 2014 Goals

• Test capability and efficiency of solar panels• How much power can be obtained• Practicality of solar panels for industrial use• Factors that help or hinder solar panel’s effectiveness• Solar panels will charge 1.5 Volt battery

• Better understanding of electronics, i.e. arduino, basic circuits, and programming

• Videos for outreach events

Structure

• Two carbon fiber cylinders• Smaller cylinder nested inside large cylinder• 25.5 cm tall• Small cylinder: 14.7 cm diameter• Large cylinder: 19.7 cm diameter

• Two-part liquid foam• When mixed, solidifies into foam and expands• 2 lbs per cubic foot

• Polystyrene foam• House internal components

• Lexan Polycarbonate• Used to cap the top and bottom of payload
