The Havørn rocket is 2.85m long and 0.09m in diameter and is powered by an ‘M-class’ KNER solid rocket motor. The rocket will launch from the group’s purpose-built offshore launch platform in the North Sea.
Check out the group’s website, Facebook and YouTube for more information.
Video Caption: Long time since we posted a video, but we are still going strong. This video shows some of the work we have done in 2017 and until now.
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.
Not strictly in the amateur experimental type of news but well worth posting.
This is a video of the DLR MAPHEUS-5 sounding rocket from the Esrange Space Centre in Norway.
The rocket was launched on June 30th 2015 and reached a peak altitude of 256.2km, the rocket featured a Brazilian two stage S30/S31 motor combination, which gave the rocket a max speed of Mach 6.5, enabling 6 minutes of weightlessness.
