SEDS UCSD: Ignus-II Static Fire

SEDS UCSD conducted the second successful test fire of their 3D printed Ignus-II bi-propellant rocket engine, running it through its full duration burn of 11 seconds. Producing ~800lbf of thrust and fueled by liquid oxygen and kerosene, Ignus-II is the 2nd generation engine of its namesake and will power the team’s Vulcan-II rocket to 45,000 ft.

Because of the igniter design, we hard-started the engine, and because of a procedural error we ran slightly fuel rich for the burn. More details to come as we further analyze the data!

Monash Aerospike

This deserved a post on its own.
I found a couple more video’s of this 3D printed aerospike online which go into a bit more detail.

Of note, the engine has multiple internal chambers, which in the future could be used for thrust vector control, as well as the regen cooled chamber, the spike is also cooled. The engine burns Methane and Gaseous Oxygen producing a thrust of 4kN or 1000lbf, the video below shows a burn time of 60sec.
