What we’ve accomplished so far
• Lamination of Foam core
• Cascading timer
• Composite hinge
• Drop test
Lamination of Foam Core
• Materials
-Foam core
-Peel ply
- Breather
-Resin
-Vacuum bag
• Process:
-cut materials
-mixed resin
-covered material with
resin
-places foam core in
middle
-placed all in a
vacuum bag.
Cascading Timer
• Tim May
• Actual timing
– Resistor/Capacitor calculation
• Comparison to Camera timer
• Power requirements of the timer
itself
– Heater/deployment
requirements
• Function of the cascading timer
Hinge Testing
• We tested the power of a
single hinge.
• We attached a 500g
weight to the hinge.
• We used 27 volts to power
the hinge.
What We Found
• The Composite was more
then able to pull the 500g
mass.
• It will require three 9 volt
batteries to power.
What we still need to know
• Will the hinges still
activate after impact?
• Can we partially power
the hinges in order to heat
our sat?
• How the sat will deploy in
tall grass?
Drop Test
Materials Used:
• Foam core
• 460g rock
Process:
• Duct taped foam core to
rock
• Dropped it from ITLL
“Lego balcony”
• Hardly any damage to
foam core; rock was
shattered, mainly due to
improper attachment
•
Deductions:
• Going to need better
payload safety
• Perhaps use an
adhesive to better
secure insides
