I admire the time you have invested into this project. You created something spectacular from scratch, and it was a success at all levels. You did something extraordinary, you are listed as a professional. The unit is cooled at high Temperatures, and the operation system is constant with no defaults detected. If the fuel capacity consumptions is low at high Rpms, it is gauged as an efficient power plant using more Air than fuel to transmit maximum power. Overall? Good Job! I like your Work. Your doing something many individuals never think about.
Thank you for the bilingual captions, my high school German was for too long ago and too basic to keep up otherwise! Did I see something dripping from the bottom of the engine between 5:20 and 5:35? Hopefully that was expected behaviour!
Hi Richard, thats a bit fuel. My connectors leaking sometimes and I have to replace the plastic tubing. They getting tough after some time. Thank you👍👍👍 Andy
Ein neues Video von Praendy zu sehen macht mir sofort den Tag! Freue mich immer auf neue Videos, ich würde gerne $ beitragen. Schau mal in ein Patreon :D
With potential for high frequency vibration, wouldn't you want your diffuser made of a forged aluminum? Get yourself some used forged aluminum piston from a high compression engine and mill them from that. Don't get me wrong the whole project super cool. Well done!!
Негода ver0, для него это запредельные технологии. Ему 3-5 кг (возможно меньше, точно не помню) тяги на его двигателях дались слишком тяжело. Ему проще купить Б/У движок, а не самому сделать.
Dann könnte man doch evtl ein Urmodell 3D drucken (pla oder petg). Oberfläche aufbereiten. Schleifen grundieren. Silikonabdruck erstellen und mit JB Weld ausgießen (quasi das Rapid Prototype Verfahren) unter Vakuum? Grüße in Richtung Hannover!
Moin, das würde gehen. Die Lufttemperatur unter Kompression liegt bei ca. 170°C. Wenn man das Triebwerk noch dem Abstellen runterkühlt, gibts keine Probleme. Ansonsten hat man Stauwärme, die über 300°C erreichen kann und den Diffusor möglicherweise verformt. Danke😉 Andy
Ah ok! Weißt Du ob die aktuelle UT-160 am Diffusor diese groben Diffusor Keile hat oder ob da außen nochmal die kleinen Schaufeln auf dem Mantel sind. Viele Grüße Christian
Also was ich eben so bei Jetmax gesehen habe, gibts den in beiden Ausführungen, wobei die "normale" UT 160 den gemischten Diff hat. Die LA Version (was immer das bedeutet) hat den einfachen Vollkeildiff. Andy
Ja was das LA bedeuten soll frage ich mich auch. Ich habe mal gelesen das es Letzte Ausführung heißen soll (quasi latest revision?). Klingt aber etwas komisch. Ich würde gerne mal in eine aktuelle Bauplan Version reinschauen um abzuschätzen ob ich das gefertigt bekomme. Turbinenrad und -stator würde ich wahrscheinlich kaufen. Beim Kompressorläufer frage ich mich ob man den konventionell gedreht bekommt! (Ich hoffe das ist ok wenn wir hier so viel schreiben?)
Hi, the engine only works with liquid fuel. I tried a 5 Liter Propan gas bottle, but there is not enough flow to the engine. So the gas is for preheating the combustion chamber until fuel is entering. Andy
Hi Oilaf, 25 Kg sinds leider nur. Die innere Skala ist in Pfund. Beim heutigen Test habe ich 35 Kg erreicht und noch 7000 Umdrehungen Luft nach oben. Also 40-45 Kg sind möglich😉 Andy
How the faq did you make a jet engine ,let alone by hand , i was under impression turbines need some exotic materials and some fine craftsmanship because they spin fast , have to be very precise , you cant make that by hand , you hand is not that precise . Its like Telescope , cant grind telescope mirror by hand it will be real bad , you need tools . Tho i never made a turbine , so i dont know , maybe you can make it .
Hi, thats no problem in Germany. There would be only a restriction if the engine would fly. In Germany we have a max take off weight of 25 Kg. Above 25 Kg the plane needs an official check from the LBA. Thats a kind of safety board, or NTSB. Andy
Hi, its not dangerous. The inner cone settles down, after the heat from the startup is gone. There are 3 stainless screws they centers the cone. During startup, the getting a bit longer of the heat. When the engine is in idle, the temperature drops and the screws taking their normal shape. Andy

Thanks a lot Andy👍👍👍
Still working on performance and thrust.
Today the engine spit out 34 Kg and still some rpm to go😉
Andy
Great! You should Make a electronic starter for the engine and use the Xicoy Fadec V10 ECU . Then you'll be set.
Hello. Great stuff. Been waiting an update from your project. Nicely done.
Thanks👍

Молодцы! Есть еще рукастые и за бугром))))
Beautiful sounding. 👍
Too good, love the safety boots while pouring 🤣🤣👍🇦🇺🇦🇺🇦🇺🇦🇺
Fantastic!
Amazing. As usual, thought.
At the startup exaust looked asymmetrical, is this an expexted behavior?
So cool :)
its a beast!
Ha ha. Wih this engine you can alredy fly the human ultralight jet! 😃 Great work! 🙂

Awesome turbojet. Will it be commercially available?
What alloy you used for the turbines?
very good
YES ANOTHER UPLOAD
If you use this in lower speed, what will it sound like? Could you please try it?
What sort of machine do you have to trim down the diffuser?
Great
How much HP does it give?

Sehr gut 👌🏾
Hi sir I have a question. How do you calculate the diffuser angles ?
nices teil :)
do you mind sharing plans? planning to build one :)
Hi.
I dont have plans from the engine.
All is created in my brain.
Andy
Du bist eine wirklich kluge und genaue Person
Hi Ramiz,
Danke dir☺

Игорь Негода ver2))
Класс.
Негоде до него как до Москвы раком
Негода ver0, для него это запредельные технологии. Ему 3-5 кг (возможно меньше, точно не помню) тяги на его двигателях дались слишком тяжело. Ему проще купить Б/У движок, а не самому сделать.
Wirklich genial! Ich grübele grad was der Diffusor thermisch aushalten muss. Reichen da knapp unter 300grad Celsius?
Dann könnte man doch evtl ein Urmodell 3D drucken (pla oder petg). Oberfläche aufbereiten. Schleifen grundieren. Silikonabdruck erstellen und mit JB Weld ausgießen (quasi das Rapid Prototype Verfahren) unter Vakuum? Grüße in Richtung Hannover!

How does this engine work with gas fuel and liquid fuel?
Hi,
the engine only works with liquid fuel.
I tried a 5 Liter Propan gas bottle, but there is not enough flow to the engine.
So the gas is for preheating the combustion chamber until fuel is entering.
Andy
Habe ich das richtig gesehen, 55kg Schub?
Hi Oilaf,
25 Kg sinds leider nur.
Die innere Skala ist in Pfund.

Und sie haben einen starken Willen
I hope to see runing in a RC plane some day xd
He worked very hard on the engine. If he puts it on the plane and it crashes. It would be so terrible
He already stated that it
1. was to heavy
2. is meant for display
Tho, it would be hella cool if it would fly :)
@@elitenoobinator so sad
@@hamzaterzi8801 bruh, indeed
8:14 scheiss auf die Brennnesseln da bin ich voll bei dir
Danke👍👍👍
What happened if i get my fingers in turbine when it start
What are the legalities of this? Is this allowed?
Yes.

4:59 - 5:05 Back part moving, looks dangerous.
