Introduction
Space debris are a serious hazard to continued Space exploration
Dead CubeSats are hard to track
De-Orbit Device Project aimed at Prototype for 1U CubeSats

Overview
De-orbit Device Project is multidepartment effort between the Mechanical and Electrical Engineering Departments
MAE 435 Group’s goal to build the physical prototype

Inflatable

Materials
The new polyester film has been received.
The valves and sealer have arrived.
Construction of the inflatable has started.

Questions/Concerns from advisor.
What is your overpressure? (If you inflate the bag with benzoic acid vapor, your overpressure will be extremely small, but you won’t have the gravity problems).
Do the wrinkles move about during inflation or does the pattern persist? (Is there a way to predict the size and location of the wrinkles?)
Most importantly. You have the deflated dimensions of your “pillow” (that is your baseline cross sectional area—a key element in predicting the aerodynamic drag). Can you measure the actual cross sectional area of the inflated pillow and can you measure it as a function of inflation pressure?

Heating Element
Our team had developed a prototype heating element consisting of electric wire and powered by 4 AA batteries.
We are looking at alternative heating sources due to size and power constraints.
An E-cigarette is a viable option.

Deconstructed E-Cigarette
A = LED Light Cover B = Battery C = Atomizer (heating element) D = Cartridge

Design Concerns
Much smaller than original prototype
Can reach higher temperatures
Integrating deconstructing E-cigarette into CubeSat for remote activation
Connecting E-cigarette cartridge to the inflatable balloon.

Future Testing
Place the gasket on top of the membrane
Have the sharp edges rounded out
