Static Thrust Test Stand (STTS)

Details regarding the first iteration of the STTS system

I have been working on a way to measure thrust over time of my rockets for a while now

After a good friend of mine got me a 5kg load cell and alot of procrastinating I put it together

Minor Rocket Launch Failure

A minor failure of the launch, not a minor rocket failing to launch

I have recently made 3 rocket motors based on sorbitol
I still had 2 left over, so I decided to try them instead of letting them absorb moisture and become useless

Since the previous one was such an unsuspected success … Read More

The Plan

My very optimistic phase 2 plans

After the first really successful (if unintentional) launch I have decided to take this project to the next phase

This means getting the permits necessary to make propellant and launch rockets legally, and working on a full rocket that is … Read More

KNSB Rocket Propellant and Launch

First test launch of a Sorbitol based sugar rocket, and the procedure used to make it

First off all this will be in two parts
The making of and the first launch
This is to keep things organized and readable
so, first:

The Making

After some research, I had concluded that the best and easiest form … Read More

New Rocket Propellant (Gunpowder)

Details from a short detour about using gunpowder as rocket fuel (which ended up going nowhere, literally)

After some correspondence with a rocketry veteran I am shifting to rockets using gunpowder (This turned out to be not true, I instead switched to the superior KNSB propellant)
This would come at a increased burn rate and chamber pressure … Read More

Rocket Launch 3

Footage from the trails and tribulation of unguided short range near horizontal rocket tests

A Test had been conducted testing the Electrical Ignition System and the engines ability to propel themselves against gravity

Improvised Ball Mill, Followup

A short followup about the first ball mill experiment, detailing the resulting fuel

I have made a new batch of fuel with my new ball mill, and even though it was not perfect and I could have left it running longer, the fuel resulting from this process seems to be incredibly potent

The … Read More

Improvised Ball Mill

A short about The Wondrous Mechanical Maurits™, which was intended to grind down chemicals and mix them together

One of the problems I had was the effort required to make the rocket fuel mix, it took hours of grinding with a mortar and pestle, which just wont do
Introducing, the ball mill “Mechanical Maurits™”
