Homemade Jet Engine, New NGV Building And First Start

[@drsamuelk]

Finally a home built jet engine that works with few glitches. Bravo

​@@PraendyGroßartige Arbeit, Sir. 👏 Anscheinend verfügen Sie über jahrelange Erfahrung und ich wäre Ihnen dankbar, wenn Sie mir helfen könnten Als Abschlussprojekt möchte ich ein Turbinenstrahltriebwerk mit 10 kg Schub bauen. Aber ich habe Mühe, ein zuverlässiges Design zu finden. Haben Sie eine Idee, wie ich ein praktisches Design bekommen kann? Und können Sie mir aus Ihrer Erfahrung bitte einen Rat geben?

[@williamwinsor7376]

Best start so far! I would be very happy.

[@moviemenia9276]

What is the max thrust? And what is the fuel consumption rate?? Can you confirm that?

[@plav032]

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?

[@ArcturanMegadonkey]

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

[@Praendy]

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? I like the axial comp sound👍👍👍 At the moment I am building a bigger housing and diffuser section. Still looking for thrust😁 Andy

[@ArcturanMegadonkey]

@@Praendy Hi Andy, the axial engine and the Barjay replica are Phills although I do have a couple of his engines which are smaller. I used to help Phill at this workshop when he was making the Wasp engines and others and sometime about 6 years ago we met up so I could film the axial and Barjay replica. Look forward to seeing more runs and improvements Paul

[@RV-ky1dr]

Congratulations!!!

[@HansMueller661]

Cool! Toller sound. Kannst ja den Nachbarn erzählen, das ist die neue Wärmepumpe 😂😂😂

[@Yaivenov]

Your work is an inspiration!

[@pauljs75]

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?

[@Praendy]

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

[@0512d1d]

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.

[@yeetmeat_]

about the compressor part, were you able to buy a shroud that fit well with the compressor? if not, how did you design and machine the shroud to reduce the gap between the compressor and shroud?

[@raygun26]

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.

[@melissarainchild]

Hallo, das ist eine tolle Leistung, aber ich möchte wissen, welches Metall in den Klingen verwendet wird

[@donniewatson9120]

I love that sound!!!!!!!!!!!!!!!!

[@therflash]

Just a little PSA, if the turbine or a compressor stage explodes, it will send a lot of very fast shrapnel in all directions perpendicular to the main axis. Please don't have people sitting in the death zone.

[@djisydneyaustralia]

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]

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

[@djisydneyaustralia]

question... Thermal expansion of the blades and inner walls ? may have them grinding the wall and blades grinding?

[@321aguila]

Right but the walls expands to, not at same rate but it expand

[@BekKOWF]

what is the most efficent blade angle for n1 n2 and n3 shaft for turbojet engines (totaly not for backyard f16c viper)

[@Praendy]

??? I dont know😵‍💫

[@ArneChristianRosenfeldt]

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.

[@af0ulwind115]

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?

[@boydjensen3161]

Quite an engineering feat! Now you will have to find something to mount it on... a huge model plane!

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.
