First rocket engine assembly!! Not all parts are shown, injector is complete but not inserted.

Nozzle! It's like....ridiculously light. Also, massive props to people who work with composites, this stuff is gnarly... but amazing.

Ah, Texas. The land of trailers. Here's ours. We are going to mount a rocket engine test stand on it!

Engine mount tubing :)

We got our cryogenic lip seal!

This isn't them but they have a wound steel spring inside them to seal against dynamic surfaces with significant thermal expansion due to large thermal gradients. In our application it's used to seal the injector to the LOx dome.

I like venturis. Especially cavitating venturis. They prevent engine from disassembling upon firing. More on them soon.

We got a 3d printer!

This is AJ the frog. Say hi to AJ.

Cool view of 5 axis CNC machine. This machine made our injector.

Thanks to Multi Machining for sponsoring us.

The final objective....

#rocket #render

[Lloki MK1 ( archived account) @LlokiMk1]

Possibly the world's simplest ROCKET ENGINE test stand.

Can withstand over 10klbf in sims.
Hollow square steel tubing.
Just over 3 feet long.
Portable.
Crazy strong...

Wondering where the real injector is? See our other posts, and thanks to Multi Machining for making us not one but TWO injectors. Best machine shop ever.

Under certain conditions, including in rocket exhaust, gases can become OPAQUE. Using the shape of the mach diamonds, the speed of the gases can also be determined.

Rocket engine injector.

Milled from Cu145, based off of the LR-101 injector, 50% more thrust at 1.5klbf. Cold flow looked good!

One valve
Two valve
Red valve
Blue valve
Here's our Press valve :)

A nice military surplus Marotta solenoid poppet valve. Crazy high specs: normally closed or normally open, super high cv, 5000psi max.

Test stand propellant valve. We got our hands on a LR-101 propellant valve. It handles both oxidizer and fuel. Might fly it too...

Aluminum Rocket tank tubes!

From left to right, these tanks, once bulkheads are welded, will house LOx, Kerosene, and Helium.

Picture Monday :)

Sponsor Sunday!

Thanks to Sergio Bustamente and Blake Boyd from Matador Engineering and Arrideo for supporting the project and leading our latest round of fundraising.

Matador provides owner training services and Arrideo helps prepare HVAC professionals for the PE exam.

machine shop. We are expecting a shipment of items from our mentor in California which will include parts of the engine, the test stand tanks and the flight tank tubes.

Status update Saturday!

These are our test stand tanks. Over the past week the design of the engine test stand has been completed. Data acquisition system has been sourced and is on order. In terms of machining, our flight tank bulkheads are nearly complete but still at the ....
