    It is just a first attempt. It had almost no thrust. But i made it longer and added a more powerful fan. I will add more pictures, and show more videos. In this form it is just a large blow torch.

    I wonder if he should look at this?

    Might help.

    Sigh, to be a jet engine you need to be producing thrust - From what I could see this is not so.

    When you have air + Propane + combustion chamber is a goo blow lamp at present. Nice hot flame but not much jet engine

    I just watched the video (hold the camera the right way up next time!), and I don't see any "jet" at all.

    You need to show us photographs (not video-grabs) of the actual build - as far as I can see, this is currently just a fairly large Bunsen burner.

    How much thrust are you developing?  Or, unless the color correction is WAY off in the first picture, are you just burning stuff in a can?
