[HiDARG-MEMBERS] Fwd: [SS2S-Main] Our largest flown sugar rocket...12" diameter

[Jeff Moore]

A lot of you have an interest in my other hobby - high power rocketry.  The
forwarded message has a link to a short video of a launch of a 12-inch
diameter 12-foot tall rocket launching with a sugar motor.   Normally, we
use solid propellants based on APCP (ammonium perchlorate composite
propellant),  This rocket was powered by a KNSB motor (potassium nitrate
sorbitol) with the sugar being the sorbitol component.  Sugar motors are
not as energetic as APCP motors and are lower in performance as a result.
This launch was done by the Sugarshot to Space team and this represents the
upper stage of a 2 stage vehicle that will be launched into space
(sub-orbital).   This launch was reportedly under 5000 feet high and used a
much smaller motor 100mm than future flights will - the rocket is designed
for a 12-inch diameter motor and used an adapter to fly with the smaller
4-inch diameter motor.   This was a test of the avionics and recovery gear
and will likely be the lowest flight this vehicle will see.

Enjoy the video!

We launched a 12" diameter and 12' long sugar powered rocket this week.

Great launch and recovery on this test flight of the airframe, avionics,
and recovery.

Rocket weighed 135 pounds without the motor...our 12" grains weigh 135
pounds each.
