We are looking to restart engine testing soon, likely with a propellant catalyst. This will hopefully improve thrust on Ashengine. We may also try out a new propellant packing system, though this is just a suggestion at the moment and hasn't been developed at all yet.

Ashengine-3 static fires with odd results. The engine performed worse than last time, likely due to the goofy ahh propellant experiment. The case and nozzle proved themselves again though! Thrust curve and additional info will be available later.

Slow-motion video and an out of focus shot of the Ashengine-2 static fire. These are definitely not the greatest but here they are anyway.

Adjusting again to Thursday. This should be the last change.

We are adjusting test day to Wednesday following a propellant packing crashout of epic proportions.

Stupid Propellant Experiments vol. 1: We are adding copper sulfate pentahydrate to our latest batch of propellant. A motor will fire with this propellant tomorrow. Hopefully, the flame color is affected at least a bit. idk

Ashengine-3's chamber will begin printing today. The nozzle is being redesigned, and could also be ready today, but will likely start printing tomorrow.

The smoothed profile of the nozzle on the inside along with the blowby prevention eliminated the two failure points of Ashengine-1, meaning this design should now be able to handle higher thrust.

The inside of a fired Ashengine. The bottom of the nozzle section is clearly visible and shows minimal ablation. The addition of epoxy into the nozzle-chamber joint seems to have helped immensely by preventing blowby. Image 3 shows the cross-section of the engine for reference.

A SUCCESSFUL static fire of Ashengine on its second test!! Thrust measurement data was acquired. Expect more video soon!

We are targeting a time around 3:30 PM for the Ashengine-2 static fire. There will be no public livestream.

Data measurement checkouts have been performed on TS-2 prior to tomorrow's anticipated static fire and the test stand is operating properly. As shown in this image, it was able to measure a maximum of 94 newtons of thrust during testing.

Development on Ashengine for its second static fire will resume within the coming days. Expect more news soon.

The test stand has been completed and is functioning properly. The design is much better. There are no glue joints, the Arduino is protected, and the holddown system is much simpler (just two bricks, no rope). The shortened Ashengine will fire in this stand soon.

Construction is going much smoother than the first test stand and is well underway!
