This isn't really much of an update, as there aren't really any pictures to see or a lot of text to read. What there is, is a couple of videos that speak for themselves. The videos were taken during testing this week, which I decided to do because the new scale came in.

Test results with 63 lbs of thrust

I tested the engine again, and hooked up the new game scale I had ordered on Ebay. The scale reads all the way to 300 lbs, so it should be capable of handling just about anything I can throw at it. It also has a nifty slider on it that will show the maximum thrust levels the engine has achieved and hold that reading until it is manually reset. These tests were run with the 10 gallon per hour fuel nozzle, and the thrust nozzle attached to the engine.

Testing fluke

During this test, I pushed the engine by throttling up and down quickly, and finally I throttled it all the way up from almost idle speed. I did this very quickly, and the results were a bit strange. I have not repeated this yet, so I do not want to call this a definitive result. You can be the judge for now and see the thrust results as they happen and are captured on the scale. If the flame out had not occurred I would have been happier. If I can achieve this thrust rating again, and consistently obtain the result without a flame out of the combustor, I will then recognize it as an achievable level of power.

More testing results to come, along with a few surprises too. I will start working on the afterburner soon as well, once I have sustainable and repeatable test data. Thanks for stopping by, and be sure to help us out so we can bring further results to you faster. See you soon!
