KILO monolithic moonburner – liner
To cope with the extended exposure to hot gases due to the moonburner grain configuration I decided to apply additional phenolic protection on the inside of the liner. Rather than adding a full length casting tube I decided to cut the casting tube in two pieces and applied an additional layer of phenolic near the core
KILO monolithic moonburner – casting set up
This post is used as a repository. Pictures are pretty self explanatory. Off set core 17,5mm.
KILO monolithic grain fin core – sneak preview
Sneak preview of a new to be developped motor. The core design was copied after excellent test results from AV. The plan is to step up our APCP motors in size without the need of costly matching phenolic liners and casting tubes normally required for BATES grain motors. This fin core design allows for a monolithic cast grain with a neutral burn,
LRE 2018 – Launch
We had a blast! GIGA II flew to 8.792m and approx Mach 1.7. Click here for for further details.
GIGA II – Nose cone avionics and electronics bay
Nose cone avionics The nose cone avionics of the GIGA II have been re-built after the CATO. Keeping the original basic design with some minor modifications. One of the failure modes evident was that the nose cone tip with central M6 threaded rod was missing and ripped itself, including the nut, through an aluminium U-profile taking
KILO 5GXL – Slow white static test 04-02-2018
On Saturday 04.02.2018 we organized a small static test party. I wanted to test the KILO 5GXL motor measuring both thrust as well as chamber pressure. My current set up only allows for chamber pressure and to determine the Isp I needed actual thrust readings for which I needed the static test stand from LD.

Slow White unimodal pourable propellant – Charaterization tests
Characterization tests of the Slow White pourable propellant with unimodal AP 200um propellant at Kn 424-643. This is a 60mm OD / 50mm ID test motor with 2G neutral burning bates grains. As the name already implies the propellant is indeed slow burning and needs a high Kn to get the most out of the Isp in this short motor.
Slow white pourable propellant mixing with all 200um AP
Mixing of a small 700gr batch of “slow white” APCP pourable propellant for characterization tests. Actually this bimodal formula calls for ¼ part op 90µm AP but I have found this difficult to obtain. Hence the all 200µm AP. The AP I have contains 25% by weight of particles 0-150µm so I hope this comes close to the
