I always thought those Germans have a factory at their backyard

LOOL I use the EXACT same electric lighter for the ignition on my home turbine build. Im going to wire it into the combustor liner, to keep me as far from the monster i created as possible, however the voltage drops the longer you make the wires. I had a thought of stripping the rubber off the wire ends, & inserting them into thin glass capillary tubing for higher temp electrical insulation. you're an inspiration.

German precision consisting of grind stones and brute force. Das is gud. 😂

Das was du machst, das war mein Kindheitstraum, sowas zu bauen. Absolut stark! 💪

Your work is an inspiration!

This is working really well, that NGV made a difference. please don't allow anyone to stand in line of the rotational axis of the turbine wheel when it's running, when they let go the parts fly out sideways especially with no nozzle on. I've seen it/had it happen a few times

Hi, I know the hazard areas around jet engines. So far all went well and the max rpm (70 000) is far away. Do you own some jet engines from Phill, or did you record the videos during a testrun?

Look forward to seeing more runs and improvements Paul

good job wonderfull machine respect and well made. cooling is important especialy the bearings. i had the same problem with cooling and lubrication to the bearings it sounds that the turbine touches the NGV system axiale. i think maybe 2 mm more clearance will solve it.

Best start so far! I would be very happy.

Very cool, throttle response seems good.

Seems like it runs pretty good once started. Might need to figure a way to keep it spinning on cool-down so you don't get any warping or other similar issues. My limited understanding is stopping a jet turbine while it's still hot may lead to bad news regarding its maintenance. And is the scraping at the end on the outer periphery or is it the bearings?

Hi, the ngv is not the problem. I figured out the engine housing, where the ngv is screwed in, is a bit warped. At the moment I build a new "bigger" housing and the problem will be solved. Usualy I use a 90mm electric impeller in front of the air intake to cool down the engine. Thank you😉 Andy

So i am a bit of a curious man, and i wonder if one could have the fins mounted from a rail on the housing that spins inward with no central shaft or secondary purpose for a shaft such as to move the air around it in a configuration to cause the bottle neck at a rocket expansion cone just after the fuel is mixed, so that when the air fuel mixture exits the choke point the compression of the air is great enough for it to combust the fuel in the cone for maximum thrust... secondary air stream around the outer circumference of the rocket cone to create force vectoring?

That’s a lot of dank Mathiases.

Needs some cooling air around the outside of the stator to prevent too much expansion. I'm worried about material strength with that kind of RPM and heat, did you account for blade creep?

I know of several companies that make small jet engines in Europe. Could you possibly buy fuel pumps for jet engines with a thrust of 100 kg or more? For example the fuel pump of jet cat p1000 or pbs tj 100 and tj150. I'm looking for a fuel pump with 3lpm performance at 6bar. They don't answer my emails. can you do my favor? If I can't buy a pump, I'll have to make the pump myself. Pump development is difficult because there is no company that makes a small amount of small gears or the like.

Ah einfach super!!!!kann leider nur einen Daumen hoch gehen !

On startup the flame was ignited around 8 o'clock, I noticed flame exhausted around 3-430 o'clock on warm-up. Is this because there's a localised flame front for each combustion cycle as it warms? Do you have internal ignition? Or once running it's in auto-ignition from previous combustion?

@Praendy

Жыл бұрын

Hi, There is a lighter in my hand to ignite the fuel. Once ignited there is a steady combustion like a gas torch. During spoolup the fuel is on the lowest point and because of the direction of rotation the flame appears 4-5 o clock, until the idle speed and the pressure inside the engine has stabilized. Andy

1:43 it should be opposite, blades facing the hole inwards, and an outer mounting system with ball bearings, like a tank turret ring. Then, the turbine can be made any length.... creates a fire tornado, which is great, also quieter.

Another way of increasing efficiency in a somatic way (same thing, slightly different variation), is changing the type of air intake, and the type of nozzle. At that point, you want it to run as effectively as possible, on the lowest quality fuels, so it can always go up a fuel grade and work even better.

Hydro turbines introduced so funny names, but I understand that axial compressor blades mostly lie in a plane ( small angle ) to press into the chamber. Turbine blades on the other hand are "vertical" at angle 90° for maximum torque. So I understood that the exhaust velocity is far above the velocity of the blades? So it seems like that we could just place counter rotating n1, n2, and n3 ( co to n1 ) turbines in series. With guide vanes before and after this stack.

Beautiful

I think it will be Whats we call 1.4301 oder auch AISI 304 (V2A) und 1.4404 oder AISI 316 (V4A). I’m pretty sure!

Hi John, The engine casinh in the back is not very hot in idle. ~150-200°C The exhaust temperature is much hotter 500-700°C. So it is possible to touch the engine a short time, to feel any vibrations. Andy
