UPDATE 20170907: Due to the KNER propellant misbehaving during casting, I opted not to invest any resources in this KILO 12G KNER project anymore. What I noticed during casting KNER in the casting tube is that the solid KN particles settled towards the bottom of the grain. Leaving 25mm of plain ER at the top. With the normal

Final thoughts on the CATO / overpressurization of the KILO 12G KNSB motor at the LRE 2017 launch: The motor had a very conservative port-to-throat area ratio of 1.5 to prevent velocity based erosive burning. This resulted in a higher than necessary, Knaverage of 700 and thus higher Maximum Expected Operating Pressure (MEOP). Mass flux based erosive burning. Little has been described about
She’s finished and with the LRE launch confirmed for 29-30 April 2017, we are go for launch. There is some backlog on the construction updates but these will come shortly.
After some struggles with the high L/D ratio EDPM liner I managed to find an approach which worked well both inserting the liner into the casing as wells as inserting the grains into the liner. Below sequence seemed to work best: Talc both the casing and liner (in & out), remove excess talc. Insert both Full
After having loads of fun with the Wildman – Intimidator 5 it is time for a new experimental rocket. A minimum diameter rocket for some serious altitude. Based on the very succesful KILO 6G motor with a higher total impulse, more grains and updated with a light weight 86x3mm motor casing. Rocket will be made “sustainer-ready” similar like de DECA
