SEDS at UCSD will attempt the launch of their Vulcan-II rocket on Saturday, featuring the team’s second iteration 3D print Ignus rocket engine. Ignus-II, as it is dubbed, is printed from Inconel 718 and fueled by liquid oxygen and kerosene, producing 800 lbf (3558 N).
Ignus-II will power the 8″ dia (0.2 m), 22 ft (6.7 m) long Vulcan-II rocket to 35,000 ft, becoming the second rocket the team have flown with a 3D printed rocket engine.
Vulcan-I first flew on May 21st, 2016, becoming the first undergraduate rocket powered by a 3D printed rocket engine to fly.
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!

The student team conducted the first hot fire on their new test stand, which also happened to include the first hot fire of their newest 3D printed rocket engine, Ignus-II. Ignus-II is printed from Inconel 718, produces ~ 800lbf (3.5kN) of thrust and burns liquid oxygen and kerosene, the engine improves upon the earlier Ignus-I engine.
The test stand is also up for hire for your own university projects!. Check out the link here for more info!

The test was conducted on June 16th, 2018 and marked the first test of both Colossus and Ignus-II. This completes the Verification and Validation stage of Colossus, meaning that Colossus is now available for other university team use!
And no better way to test the new test stand than with the new engine!
SEDS UCSD has wrapped up work on their new static fire system, Colossus.
The universal test stand offers cryo compatible tanks on both the fuel and oxidiser side, a structure designed to withstand 5000lbf, multiple pressure transducers and load cells and is available for YOU to rent to test your own rocket engines!
Check the video out below, it is great to see a student team put so much work into a test stand. This will definitely make life easier down the track when it comes to multiple engine testing/configurations with such a robust and thought out system.
Video Caption: Thank you for joining us for our unveiling of Colossus, our student-built static fire test stand! Colossus is rapidly approaching completion and will soon be made available for student propulsion research at minimal cost.

The team have been making steady progress on their Colossus Static Fire System, when complete the stand will be able to handle rocket engines up to 5000lbf and will be available to rent for your own projects! Such a great idea, enabling easy and cheaper access to engine testing.
The Students of SEDS UCSD have been hard at work lately putting together their Colossus Static Firing System.
The static engine test stand mounted to a car trailer will be capable of testing engines up to 5000lbf of thrust at 1350psi, with cryogenic capability on both the fuel and oxidiser side. This opens up the possibility to use liquid methane as a fuel for your project.
The trailer will be made available to rent around October 2017.
This is such a great idea for individuals/groups starting to design their own liquid fueled rocket engines and not wanting to pour a lot of money into a test stand while keeping the project relatively low risk. I hope this see’s a lot of business!
