Hi Dave, I personnaly beleive that the recording is still something we must do. Even if our engine is not performing, I beleive we need a milestone to start with. This event would teach us how and what it looks like, we could also try to image the wave form. After that, we would have something to st...

Heyyy Raymond, Don't say I am not a good boy for you ... he he he. A bit off topic. Does anyone know what the pressure range is for a Coleman propane canister? Does anyone have experience using them for propulsion experiments? To make sure my information on Coleman bottle were 100% accurate, I calle...

Hi Raymond, For your question : A bit off topic. Does anyone know what the pressure range is for a Coleman propane canister? Does anyone have experience using them for propulsion experiments? The answer is the same for all containers. From Colman bottles to 500 gal. tanks and ect ... The pressure is...

Hi Raymond, Nice to hear from you... Taugh you fell asleep on your desk ... he he he. As for the Gluey calculations not permitting new engine design, I am not surprise that you say that, because on my side, every time I try to do reverse calculations or even do normal calculations I always come to t...

Okey guys, As for the ram air issue ... Look in the attached image were the ram air is applied. Note that only stage 1 and 2 get pressurized. I even think that at high velocity rotation, stage 3 can become under vaccum (ventury effect) So .. For the guys that were interested or puzzled by the "Ram A...

Thanks for the reply, Calculation could probably not give the exact location or lengt, but it could at least give me an idear if I am way off, considering I operate in cold weather. Also remember what Eugene says in his analysis. The third stage (including the burner) and the second stage are tuned ...

Man ... I am a bad boy, Guys, I think I got it. I think I know what is wrong with my engine. Refering to the Gluey manual, section titled "Analysis of Sonically Tuned Intake" attached to this post, I think I know what is wrong and what tuning is (Thanks to you Paul ... he he he). Using Gluhareff cal...

Paul, By all means, I did not take that as an insult, far from that. I am only trying put every body at the same level, informations wise, solve all issues one by one and put aside the ones that we already know. Don't stand corrected my friend ... Continu to investigate, like we all do ... He he he....

Hi again guys, Okey ... I know that some of you that read this forum are new or come and go on this threat subject, wich is the Gluhareff 130R power failure. Alot of time, question about dimensions arise and that understandable, from someone that just arrive on the forum and did not get the entire s...

Paul, Since the engine in the 3 photos that you posted did not have complete flares, I thought it was worth asking... A 90° flair is complete when a 90° change of direction as occure. Of coarse, you can have different radius witch make then smaller or larger. After your post, I when my self to do ...

One more thing guys, I often heard some of you mention that the Gluey engine is like an organ pipe. Even Craig wall, on many discussion we had, told me the same thing. But a organ pipe ... Can be adjusted or tuned. They use a diapason, you know, that little thing that look like a snail fork and they...

Hi Paul ... Guys, Have you verified that the straight section in the propane ejector nozzle is approx. 2.5" long? Yes Paul, as mentioned in a previous posting our engine is an accurate production as per Gluhareff drawings. Finally, in the "Plans and Instructions for Building the G8-2 Jet" from Riley...

Raymond ... or others guys, if you have the answer, This made me think ... And I have a question : While the engine is not running, what if I would blow compressed air or other gas, into the intake stack at 225 psig. Would there be a simple way to record or visualize that 3/4 wave lengt? What would ...

Hi Raymond, To answer your questions : First when I operate the engine, we usually follows the Gluey method. At first, when we start the engine, we let it warm-up @ around 50 psig. At first, is only soft nozzle jet sound and the engine is just a torch. When getting warmer, is goes into a sort sonic ...

Hooo ... One more thing Zoltans.

If I understand you correctly in what you said, the engine performances can be screwed only by a bad operation or warm-up conditions, is that what you are saying?

Thanks,

Luc
