ROCKET STATUS:     Retired
The rocket has undergone many developmental changes through
its design and launches. Our first model was 72" long,
had three fins in the for and aft sections, and used a G-64-7W
rocket motor. It used a piston system to drive the internal
recovery devices out at ejection, but it failed in execution.
It used a 42" Ultra X-Type chute to bring the sustainer
back to Earth while the nosecone was recovered using an autogyro
"helicopter" method. Check out test launch #1 for
the flight of this design.
The second revision was 12" shorter than its predecessor.
It featured four fins in the aft section alone. This seemed
to help the stability tremendously. It would use a piston
system as well as 42" Ultra X-Type chute and autogyro
rotation for means of recovery. A G-64-7W rocket motor powered
its flight. Check out launch #2 for this design's test flight.
The third revision is almost the same as revision 2, but
the piston was removed and the rocket was lightened by the
removal of extra unnecessary mass. It used the same 42"
chute and rotor blades as those before it.
Revision four reintroduces the piston system, although improved
upon, due to the ejection troubles we have experienced with
the others. A smaller 30" X-type chute is being used
for the body, as well as stock 600mm rotor blades.
The latest update has been changed so that the rotor system
has been removed. The rocket now uses two seperate parachutes.
This provides more reliabiliy, simpler design, and easy adjustment.
Plastic tubing in the payload bay and sustainer is used to
strengthen the body, but a paper tube midsection allows the
rocket to remain light and repairable. |
