https://twitter.com/copsub/status/1309177296679579651Last video on soldering our machined rocket fuel injectors (bit.ly/3crKnMF ) got a few of you asking if we dropped the idea of testing 3D printed swirlers. The answer is no! Last week @DigitalMetal3D sent us a bunch of them, organized here in a BPM5 engine configuration:

Gearing up to test 6 different injector configurations on our 5kN engine soon, before we populate an injector area 25 times larger than this one for Spica's 100kN engine. 🚀

https://twitter.com/copsub/status/1314620463461654530Tuesday we received the long-awaited container for Spica's 100kN rocket engine test stand! More parts are on their way, but before they arrive, have a sneak peek at how it will roughly look like!🚀

https://twitter.com/copsub/status/1322262354365763585We have now upgraded electronics for our coaxial swirl injector water flow test stand to make the data collection process more automated and we have also machined a new metal housing for the swirl nozzles. This means we expect to start mass testing >100 swirlers this Saturday. 🚀

Looks good, but I found the "water on the window" effect a bit annoying.

https://twitter.com/copsub/status/1331675429309177861WE DID IT! We made our first coaxial swirl injectors for the BPM5 rocket engine! There's still a few variants to go, not to mention leak & water-flow testing, but we can wipe off some sweat now. Things are looking positive and we're aiming for lots of engine tests around Xmas! 🚀

https://twitter.com/spaceintellige3/status/1340936696934899713It's alive!🚀 Spica's 100kN rocket engine main valve actuator works thanks to Adam! It's his MSc project at @DTUtweet. Precise control of propellant feed valves is essential in the engine start-up sequence and we're thankful for @WITTENSTEIN_SE helping us find the right gearbox!

https://twitter.com/copsub/status/1355230172266508292Rocket engine fuel injectors go through a lot and are often under lots of pressure! 🚀
They definitely deserve a nice, warm, preferably ultrasonic, bath once in a while. Especially after they have just been soldered.
