rocket engine came in the mail :3

@kegrocket who up tapping injector ports in the ethereal plane

Big tap. Expensive part. 3D printed fixture. Undisclosed location.

A front-row seat to SpaceX CRS-34 docking 🚀

just landed a job working on rockets :)

I just realized why all of my FEA models are trash: I’m the target of a sophisticated and sustained cyber-physical sabotage campaign attributable only to a nation-state adversary with near unlimited resources

@83dollaroring try c145 / tellurium copper its goated

printing copper parts that absolutely did not need to be printed just because Cutting Copper Fucking Sucks As Well

@stefan_salaices i think i need to post more

Got my Ares internship thru 𝕏, got fired from SpaceX thru 𝕏, got hired at Orbital from my boss seeing my 𝕏 post. I’m lifetime up baby.

@83dollaroring undergrad brazed tubes wen

have undergrads ever built a non-saddle jacket or printed regen chamber

@LukeLuk10574362 cheap electric linear actuators they have a decent amount of backlash but work well enough for our purpose

@YikesItsTim What kind of actuators do you use?

Tee Vee Cee

@kegrocket its closer to +/- 20deg, constrained by the tierod ends at the ends of each actuator we only use +/- 10deg in software tho

@YikesItsTim Looks like its got capacity for +/- 40 degrees

@83dollaroring jackass workholding you say?

another DIY project with jackass workholding has hit the timeline

@unrocket ended up switching to a CSJ design for exactly this reason

Had lots of issues getting the DMLS powder out of assemblies like this. Whatever you do don't flow liquid until you know with 100% certainty the trapped powder is out. I ended up making a fixture that would pressurize the bottom and open one an only one upper hole where I could verify dry airflow (dry nitrogen best, really dry compressed air if you cant...) Had to clear passages with stainless wire or pipe cleaners.... a lot of hand work.

Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

fully sheet metal rocket engine? @emm0sh i'm thinking rolled sheet metal, separate chamber, converging, diverging sections thin lasercut strips for the cooling channel ribs some kind of tab system for alignment the internal welds would be the hard part

@candydog23 we all gonna make it 🗣️

@YikesItsTim 11 months of searching, we out here

didn't get the job gg :(

mechE**

in totally unrelated news, if anyone is hiring me hE/aero new grads lmk :)

ball up top, etc, etc

fuckass flap
