Foreningen Rakett-teknikk写的视屏介绍
This is the 2. test of the Hav?rn rocket engine with 5,4 kg kner propellant. The data recording was unfortunately activated after the motor roared to life so only the last 1,5 seconds was logged. The motor exceeded design pressure and reached 380 kg of delivered thrust at 108/1566 BAR/PSI chamber pressure. You can see in the video the nozzle is underexpanded because of the higher pressure.
