Currently using a KNO3 and powdered sugar rocket mix with Fe2O3 catalyst and also use coffee grinder to reduce the particulate size of the KNO3 and Fe2O3. My weight ratio is:
64.5% KNO3 34.5% Sugar 1% Fe2O3
In the video, I’m using a 1 inch diameter PVC tube as my shell but I’ve been having a lot of difficulty with getting an actual liftoff. I’ve been able to get the rocket to shift a little but other than that, nothing.
Any thoughts or recommendations would be greatly appreciated! I’m tempted to change up my oxidizer to KClO4 or NH4ClO4 to increase the reaction rate but, for now, I’m not really in the market to spend more money on this hobby, especially if there’s something to tweak with my fuel ratio or something simple.
