Our Rocket Needs A Recovery System!
We've made enough craters, it's time to bring back our
rocket on a parachute. In order to eject the parachute from
the rocket some energy must be stored, and then released to
push the parachute out when the rocket reaches apogee. Model
rockets use a little chemical energy stored in gunpowder to
pop the 'chute out. In keeping with our environmentally
friendly rocket propulsion system we will use as little
chemical energy as possible. Rubber bands will push a
plunger to force the parachute out.
|
The two pins on this release mechanism are retracted by
rubber bands underneath. A length of mono filament fishing
line holds the pins out until an Estes rocket ignitor melts
through to release the parachute.
|

|
A can to contain the parachute mates with the release
mechanism, and is held in place by the pins.
|
|
A plunger inside the can, sprung with a rubber band,
pushes down on the parachute. You can see the ignitor and
fish line on the outside of the small can.
|
|
This animation shows how the cans separate after the
ignitor fires and the pins retract.

Our new recovery system needs a few more features:
- A Parachute
- A Delay Mechanism
- A Trigger for the Delay
