Here we have footage from hotfire testing our self-developed bi-liquid rocket engine. We managed to get a running rocket engine on only four attempts, a big achievement for the team! We achieved an estimated 7.5 kN of thrust, a number we might be able to ramp-up!

Inc625🤤

New engine incoming

[Propulse NTNU @propulsentnu]

Recovery mortar tested in the propulsiomn test bench? Yes indeed🤝

[Propulse NTNU @propulsentnu]

this engine is gonna be a new type of cold🥶

[Propulse NTNU @propulsentnu]

New engine, new test rig👀

[Propulse NTNU @propulsentnu]

Two crashed, one flew Mach 1.8 and one placed 3rd in the 2022 Spaceport America Cup🏆

✨5 years 4 rockets✨

280+ students have worked on our rockets. The best extracurricular activity out there?😎

Performance stats🏅

Shorter burn-time due to higher consumption than expected, but on the other hand we got more thrust.

Main goal was to prove an off-rail vel of > 30 m/s to ensure that Bifrost was aerodynamically stable at launch (something the added thrust helped with)

Bifrost full-duration static-fire🔥

This had enough impulse to lift a 80 kg rocket to 3000 m (10’000 ft)

Slow-mo if the ignintion sequence💥

Ignition source was a small solid-motor lit by an e-match. Cam was a Phantom VEO-410L at some 2000 fps (dont remember exact frame rate👀)

Launching Bifrost is our greatest achievement since our founding in 2018:

The most powerful student-buildt bi-liquid rocket in Europe to fly🚀

Norways first bi-liquid rocket to be developed and to fly🇳🇴

The best performing rocket in the category “Liquid 3 km” at EuRoC 2023🏅

After sucessfull deployment of the drogue chute, the main failed to inflate, resulting in a harder than anticipated "landing"😮‍💨
