USCRPL Graveller II Static Fire

Of note, this was the largest composite case static test fire (total impulse) by an amateur group.


Rocket Project at UCLA Test Video

As posted earlier, the Rocket Project at UCLA had a successful test of their LOX/Ethanol rocket engine, here is the video.

Looks like a great burn!

GoPro Hero6: The First Spaceport America Cup in 4K

Video Caption: In June 2017, ESRA and Spaceport America held the 1st Annual Spaceport America Cup. Over 1000 students, from 12 countries brought 92 rockets to the event.

SDSU Rocket Project LOX/LCH4 Testing Footage

As reported earlier the SDSU Rocket Project had a successful test of their LOX/LCH4 rocket engine, below is newly uploaded footage of the test that happened just over a week ago.

Sounds like there may have been some combustion instability? Interested to hear your thoughts, leave a comment below.

WARR: Cryosphere – Battleship Test Campaign

Video Cation: After 4 years of development, WARR performed the first hotfire tests of Europe’s most powerful cryogenic hybrid rocket engine. With 3kg/s of liquid oxygen massflow, the “Battleship” generates 10kN thrust for up to 15 seconds burn time. The design point of 20bar chamber pressure was nearly hit and valuable performance data was collected for further improvements. The two-week campaign included verification coldflows, ignition checks and four hotfire tests with 5s, 10s (2x) and 15s burn time.
Special thanks to all members of the WARR Ex-3 Project as well as the members of the M11 Test facility at the German Aerospace Center (DLR) Lampoldshausen for the support and guidance. This project was funded by the Federal Ministry for Economic Affairs and Energy (BMWi) during the STERN Project.

Please note: We are predominantly master students of mechanical & aerospace engineering and spend most of the time before tests on calculations and preparations to prevent severe damages on material and personnel. Please don’t feel inspired to light your own rocket motor in your backyard. Rocket science is a serious issue – if you get the numbers wrong, people die. You have some experience in mechanical/electrical engineering and want to participate, become part of the team? Feel free to send your application to

It Was a LOX/LCH4 Engine Testing Kinda Weekend

Well, what a weekend it has been, both Purdue SEDS and the SDSU Rocket Project conducted successful tests of their own respective LOX/LCH4 rocket engines or methalox engines as they are sometimes called.

Both teams intend to fly these rocket engines in the FAR-MARS prize in May and therefore are eligible to win up to $100k of prize money!

Awesome work being done by both and great to see liquid methane being given a go by student teams.

We have ignition!
