BPM-17 Injector is complete!
The injector for BPM-17 is now complete. BPM-17 is a test engine built to prepare our test stand for the next generation of Spica’s large rocket engines. While the injector itself is a highly technical Read more…
See A Rocket Engine’s Fuel Consumption! It’s Amazing!
To characterize our BPM100 injector, we needed to go bigger than any other homemade project has gone before. The Spica rocket engine will burn through 50 liters of propellants each second. To simulate that on Read more…
Finding The Mass Flow of Rocket Fuel Injectors
After increasing the hole diameter of our swirl injectors, we need to confirm how that changes their mass flow. Jeppe guides you through how to do just that.
Rocket Heart Surgery – Swirlers Need A Bit More Fuel to FLY
A quick update on how we modify our swirl injectors to test how larger propellant holes influence their output.
1st swirler data
Dear Rocket Friends, After a bit of getting ready we are now in the process of measuring how our nice little swirlers are performing. As you may remember, we got them milled at PH Spaanteknik Read more…
This Is How We Solder Rocket Propellant Injectors
This weekend we had a go at soldering our first coaxial swirl injectors which we plan to use in our crewed Spica rocket.
The swirlers have landed
Dear readers, As you could read in our last blog, PH Spaanteknik has helped us to produce a number of prototype coaxial swirlers. We have now received them and I just think you should see Read more…
Swirlers from Jutland
Dear readers, As you know, we have decided to test the swirl injector concept for BPM100 in a BPM5 scale. We believe it increases the likelihood of landing a good BPM100 design and avoiding an Read more…
BPM-5 with swirlers ?
Dear readers, The first 100 days in the BPM-100 project has come and gone. And no, unfortunately we haven’t got a working engine here in the workshop. We’ve decided to be a little more thorough Read more…
