I recently attached a tube made of thin sheet steel to the tailpipe of the 130R and I ran it. This extension consists of three segments, each implements a 30 degree bend. After the first two there is a short straight section followed by the third bend. There is also a straight section after the last...

Quite a while ago Mr. Gluhareff and I ran one of the 130R engines at 80lbf of thrust. This happened when I visited him in Hesperia. The engine was mounted on his test stand. I myself recently (1 year ago) got two 130R engines and a thrust stand. I have only ran my engines to about 60 lbs of thrust. ...

Still no luck finding a place to run engines. I am working on a boiler to preheat propane for my engines. The 130R gives me 115dB noise at 30 feet so I am hoping to make a new design without the acoustics. Try to get smooth flow coming out. I don't see a limit for the thrust, up to about 800 lbs for...

I have tried to establish a number for the fuel consumption. I took an engine (130R) out to the desert and ran it. I videotaped the run and timed it. I also weighed the fuel tank before and after using a strain gage scale. The fuel consumption I got was better than 2. My uncertainty came from the fa...

Raymond, I am still locking forward to your comment on my question : Out of the 3 events that gave use data, the CFD simulation, yesterday's running and the Gluhareff manual theorie and data. What are the 2 events that that have the closest similarity. for example, if yesterdays run and the CFD sim...
