<div dir="ltr"><div>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.</div><div><br></div><div>Enjoy the video!</div><div><br></div><div>Jeff Moore -- KE7ACY<br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">---------- Forwarded message ---------<br>From: <b class="gmail_sendername" dir="auto">Rick Maschek</b> <span dir="auto"><<a href="mailto:dmarc-noreply@freelists.org">dmarc-noreply@freelists.org</a>></span><br>Date: Mon, Sep 30, 2019 at 6:24 AM<br>Subject: [SS2S-Main] Our largest flown sugar rocket...12" diameter<br>To: Sugarshot <<a href="mailto:sugarshot@freelists.org">sugarshot@freelists.org</a>><br></div><br><br>We launched a 12" diameter and 12' long sugar powered rocket this week.<br>
<br>Great launch and recovery on this test flight of the airframe, avionics, and recovery.<br>
<br>Rocket weighed 135 pounds without the motor...our 12" grains weigh 135 pounds each.<br>
