Capsule Design
Capsule Design


Material : Extruded Polystyrene

Dense
Moisture impervious
Good shock absorber
e
Low thermal conductivity (.033 W/m.K)
Capsule Prototype
Solving an Engineering Design Problem
: Heat Exchange Model



Challenge :

1. Avoid exchange of heat with ambiant environment (-65 C )
2. Prevent Loss of pressure from the capsule
3. Find suitable material and dimensions to meet the above two requirements

The UCO Near Space Venture is an engineering project to design, construct, launch and recover an upper atmosphere research platform
Inspiration
Our Payload
At the heart of payload is the flight Computer
-Processes and logs data
Experimental Set Up:
1)Simulate data collection
2)Choose the gauss-meter Device
3)Test the Gaussmeter Device
4)Load it and cross fingers

Challenges:
- Extreme Temperature
-Datalogging
-Battery life
- Loss of payload
Near Space Venture
Magnetic Field Intensity Variation
# The use of high altitude balloons for upper atmosphere
research is becoming highly desirable by academia,
commercial industry, and military
# Current costs for rocket based launches are approximately
$10,000 per pound of payload. High altitude balloons provide
a cheaper alternative with reasonable safety factor.
# First high altitude balloon Launched in 1896
-led to the discovery of Stratosphere
# 244 successful launches reported in 2013
Deliverable 1
Completion of Flight Computer and Airframe
Preflight Test and Ground Data
Deliverable 2
- stabilizes x, y, and z axes for gaussmeter
Target 60,000 ft Achieved 109600ft
Deliverable 3 : Launch


Cosmic Radiation Measurement
Deliverable 5 :
Deliverbale 4

Questions
Safety Measures
The Balloon contained Helium , Hydrogen is a cheapear option but it is flammable

Total weight of payload was less than 12pounds, Individual parts less than 2 pounds as required by FAA

Launch was registered with FAA
all pilots in Oklahoma Airspace had info

Anyone working in the shop(s) as always accompanied by atleast 1 more person as required by our department of Engineering and Physics
Conclusion
