Testing

We went out to FAR and tested our H2O2 and Kerosene regen Motor.We ran it in Mon0-prop mode then in Bi-prop mode. It took a awhile to light in bi-prop mode, but We ran to about 80% throttle without damage in biprop mode. The Video does not really do it justice as it seems to have “sampling” effects. The Monolithic cat pack is clearly not getting good decomposition, probably leading to slow ignition. We need to rework the system test software so we can independently vary the proportions rather than have a fixed schedule. I have not yet reduced the data, but I’ll do that in the next 24 hours and post the result. You can find the you tube video .


It was a long day and when we packed up we failed to notice a melted spot on one of the vehicle tie down straps and being tired we did not double up as we usually do. So the front strap failed and the vehicle left the truck on the dirt road leaving FAR. The road is really rough and we were going about 40mph, we did not notice the vehicle depart. We noticed it was gone and had to drive back 1.5 miles to find it. Other than a cracked mounting tab and broken fitting on top of two the small stainless spheres it was largely undamaged. We were lucky.

Interesting video showing excellent progress. It is nice to see actual flames. I hope your getting close to the trust levels you had designed for.

Question:
Given the other cat-pack is working so well why did you not just use the same arrangement for this engine?

After about 100 seconds of running the other cat pack started to show signs of contamination. We don't want to run that pack until we are producing our own peroxide with less tin in it. We had high hopes for the platinum being tin immune.

Thank you for the explanation. I have my fingers crossed that it all comes together for you.

That flame was great looking, nice mach diamonds...

Looked like some chuffing in there though, do you get readings on pogo?

Hi Paul. I love your job. It takes great effort to do some tests with these substances. It's risky too. Kudos to you.
