Rotorless Turbojet Development Update 2 

I have some steel parts that will be used for testing the combustors and attempting to get a first engine running.

Thanks!

The idea is that the high speed of the air at the outer circumference of the vortex combined with the centrifugal compression will provide what compression we can get at the mouth of each burner. The burners would have a throat at the inlet and a double layer mesh where the combustion happens. There will be certainly elevated pressure there but I don't have a way to model how much exactly. I will be experimenting with the burners as the next phase, I don't think it will require incredible pressure to get it working. It would just be a limiting factor on efficiency. The prototypes will tell the real answer...

@@JaycubL I look forward to watching your progress. As an aeronautical engineer, I find this subject inspiring and hope to start my own engineering channel @some point next year, starting with a small axial flow engine that will power a fairly large drone. Keep up the good work 👍

@@caitgems1 Awesome I look forward to subscribing to your engineering channel! Since you are a real aeronautical engineer I would be honored to receive any critique or ideas you feel like contributing.

Cool that is what I will do then!

This flow-testing model is made of PLA, a plastic commonly used for 3D printing.

@@JaycubL what about carbon fiber

@@crafter2u Carbon fiber cannot stand heat like you would get in an engine like this. Steel is much better for this application. This model is plastic because it is just for testing flow with compressed air so it was easy to make the parts with a 3D printer.

Yes, Washington. I am fortunate to work at an aerospace-focused precision manufacturing company!

At home I use Autodesk Fusion360 now and Google Sketchup. I am working on ditching Sketchup mostly though, because Fusion360 just works better and has integrated CAM features.

You could use hydrogen as fuel sure. Storage and production are real problems for more than small-scale hydrogen use as fuel though. A much denser hydrocarbon liquid is what I have in mind.

There will be yes. Basically the next thing is experimenting with the combustion chambers and getting that part working, and I can model up a full-detail version with every air passage etc.

"You have to know these things when you are a king." (Monty Python reference). I would say that personality has a lot to do with it. Just natural differences in preferred cognitive functions lead some people to be good at learning certain types of things, and other people to be better at learning other types of things.

Excellent response... I’m an accountant by trade but over the past 6 months I’ve learned that I’m a tinkerer at heart.. Everything I’ve learned over that time period just came through vids, research, etc and I can’t get enough of it... It’s actually cutting into my job a bit lol
