Sugar rockets in Norway

I recently discovered a group in Norway, Foreningen Rakett-teknikk, building KNO3 rocket motors and rockets. The most recent video of a test, posted below, shows the groups work towards an L class size motor.

“This is the 7. test of the Havørn rocket engine and the first qualification test. We now believe the engine can reach our goal of 160-190 kg. thrust over a 3-4 second burn. The burn was nominal and met our requirements, outside chamber temperature reached 150 degrees celsius in nozzle end. Total impulse of 5000 Newton-sec means a full L class on this test. Next qualification test is with a better igniter and some fine tuning on the nozzle.”

The group have also been working on an offshore launch platform which can be floated out, then utilizing a counterweight system is able to be stood vertical, ready for launch operations.

“Vertical test in calm waters. The platform is a 200mm, 6 meters long sewer pipe and a 4 meters high aluminium tower. With a 162kg counterweight, we can have a 20kg rocket mounted.”

You can see more videos of their projects in action on YouTube or visit their website.
