[#12137065]

Instead of riding my bike, I've been fiddling in my shed...

...and made a jet engine

Impressive! Is that a kit?

Brilliant, now go back in the shed and attach it to your bike - this is a bike forum after all 🙂

Fantastic! awesome noise.

I used to test Aircraft engines, you just transported me back to standing out next to one running at 25% power on a nightshift, in january 🙂

😀

The though had crossed my mind - I need to get it running on kerosene first as there isn't enough energy in propane to get it up to full power. (It'll also be very under-powered compared to modern commercial ones, but that's a limitation of a home made turbine wheel, rather than one cast from Inconel.)

Thanks - it's not a kit - it's an old design from the book by Thomas Kamps.

Everything was made in my shed (on my Chinese mini-lathe), except the compressor wheel which is a spare part for an Audi 100 turbocharger. 🙂 (There's some build photos on the MIG welding forum if anyone is interested!)

Made from plans! That is a serious achievement for any model maker. I like that a lot :o) Thx for posting.

Good Lord!
Although yours has been knitted by you, so is inherently better!

If I put one of these on a bike does it become an e-bike? Asking for a friend...

When you get it going on kerosene let us know how much thrust it generates.

Putting one jet engine on a bike would be a terrible idea.

You'd be all out of balance and wobble all over the shop. No, you'd definitely need a pair of them to balance out the power!

Lovely stuff. Got plans for an afterburner?

What's the plan? Flying Black & Decker workmate?!

Ha ha - yes, he's home. He was just visiting his other residence.

@creakingdoor - you've obviously seen me ride! 🙂

That's the plan - if it generates something meaningful, then I have eyes on the panier rack on my fat bike. (Afterburner optional!)

Thank you all! 😀

Fantastic!

Build a wind turbine next to offset the CO2 emissions 😉

nah, Propane is very energy Dense just like LNG, (Hydrogen is awesome) the probelm will be with the liquid density of the fuel. You'll need to wind it up on Porpane before having Kero injected and atomising - can you do that with you're build, otherwise you'll need an electric motor to get it spinning and the injectors doing their bit.

what would work quite well is some Russian TS1 grade, it's more volatile than JET A1 kero so easier to start - do you want some 🙂 - often find people mixing petrol and Kero for this purpose (not advised though)

Seriously impressive (Just been on the linked welding thread and trawled through the history of the build)....well done!

Thanks

You’ll need to wind it up on Porpane before having Kero injected and atomising – can you do that with you’re build,

Yes (sort of) - it’s got vaporiser tubes for the kerosene, rather than atomising nozzles (it’s the way that all these “toy” turbines work). There’s a separate injector for propane to pre-heat the vaporisers for starting. Spool-up will be by driving the compressor wheel with a jet of compressed air (as in the video).

Luckily we have a tank with several hundred litres of kerosene in outside the house.

Thrust will be low by commercial standards, as the home made compressor wheel is limited to ~95k RPM.

🙂

Who do you think you are, Frank Whittle?
Seriously, that’s awesome!

A mate of mine was a toolmaker at Durham Science labs & made things for students who were from the likes of Rolls Royce. He made some proper impressive stuff.

How did you make the outer case and stand? I wish I could make things out of metal. Or out of anything that is that good.

Well impressed.

Aren't you at risk of losing your hand or arm when you wave it around in front of the intake when you fiddle with the oil tank?

That is awesome.

Loved the build thread on the mig welding forum, especially for the ingenuity of how you built things with what tools you have or could rig up.

Thank you!

How did you make the outer case and stand?

The outer case is a sheet of 0.5mm stainless steel bent into a tube with an end cap of the same material spun over a plywood former.

The stand is welded up from some aluminium sheet, ground to be pretty & then anodised.

It's easy to come out with statements like the above, and give the impression that the outcome was assured. However, the truth is that I had no idea whether / if the result would be OK, but I'm chuffed to hell that it came out how it did.

If you want to make stuff, then start making stuff. You will learn.
