N₂ORTH Rocket | Hybrid Propulsion System Test in Blow Down Operation

HyEnD is proud to announce that the N2ORTH propulsion system was successfully qualified in a hot fire test for a propellant throughput of more than 100 kg! This marks an important milestone for the project, as we now have a flight-worthy propulsion system for the launch. During the test, the rocket tank was operated in a blow down setup together with the fluid system and engine of the rocket. The ground support system of the rocket was used in order to fill the rocket's tank with nitrous oxide and helium. The test included the main operation phase of the engine and also the gas blow down after the depletion of liquid oxidizer, resulting in an overall hot fire duration of more than 50s. In the upcoming weeks, the team will prepare another test with increased propellant mass in order to unlock the full potential of N2ORTH.

The placement of that emergency phone is rather hilarious, but otherwise awesome!

Looks good! Looking forward to the launch and maybe a new European Record...

Thank you for including technical information. Was the partial flame quenching at 1:07 a deliberate part of the testing schedule, or a surprise? Either way, congratulations on an impressive achievement!

It was known that this phenomenon can happen during the gas blow down. You can see a somewhat similar behavior at our launch video of the HEROS 3 rocket. The quenching happens in the divergent nozzle section, as it can not be seen in the chamber pressure data. The influence on the thrust is not significant.

Cool. Congratulations
