When afterburner engages the rear nozzle should increase in diameter to prevent back pressure going into the turbine. Also only engage afterburner at 95% rpm and up to prevent this even more. At lower Mass air flow the efficiency will be dramatic. Almost there good luck.
Hi friend. You're building a new little engine? I'm almost finished with the mass production model now. I look forward to a fun video. I'm planning to install it on a quad bike.
@@Praendy Hi, I hope to build a turbocharger based engine over the next year. I'm still researching and gathering parts right now. Have you seen the Tech Ingredients channel? He has a very informative video on the twin tube afterburner design: ruclips.net/video/EP4Hf63zR6w/видео.html Essentially, airflow between the inner and outer tubes cools the inner tube which contains the combustion. Furthermore, due to the geometry, the inside tube helps mix the air and fuel for efficient combustion and expansion of the gases. I really like your channel, look forward to further videos. Cheers!
Hi, Could you share the ideas on how have you made the afterburner for such small engine? Do you have any models or drawings that you used or made? Regards, Eduard
@@Praendy is the compressed air start shown and explained in any of your other videos? I'm curious how it is placed inside the engine. Edit: also what pressure and rate is being used? I am curious if an air brush pump could accomplish it.
@@Yaivenov the air start is not shown in one of my videos, but its very simple. Its only a small hole in a certain angle and is located in the air intake. The compressed air is directed onto the compressor wheel outer diameter. An air brush compressor is not able to do the job. Andy
Krass, wie hast du die Turbine gebaut? Hattest du Formeln für Treibstofffluss, Brennkammervolumen etc. oder hast du einfach mal angefangen bis es klappt?😅
Hi, Die Turbine ist nicht selber gebaut. Sie ist von der holländischen Firma AMT. Ich habe nur die fehlenden Teile ersetzt und sie wieder zum Leben erweckt. Andy
Das ist eine seriengefertigte AMT aus Holland. Die konnte man mal so kaufen. Ich habe lediglich die fehlenden Teile gefertigt und sie wieder zum Leben erweckt. Andy
hello friend..its so hard for me to follow the step by step process of making a jet engine...i have watched most of your videos and mostly its like you have already sourced most parts and not making them yourself could you kindly consider such a video comprising how to make each part??Thank you

Dang, same day as the teaser on JATO?! You beautifully efficient devil, you!
Hi friend.
You're building a new little engine?
I'm almost finished with the mass production model now.
I look forward to a fun video. I'm planning to install it on a quad bike.
I wish you good luck andy! hopefully we can see this on an rc plane on youtube!
Looks awesome! Good job on this afterburner. Do you have plans for a twin tube design that could withstand more heat without damage?
Hi,
no, in this case I will try a single tubing.
Upgrading is no problem.
Do you have plans?
Andy

Your afterburner is realistic with a roar of an actual afterburner. No need of LED bulbs to emulate a burner. Is there increase of thrust too?
Hi,
Yes there is more thrust than without burner.
I have to try, how much😊
Andy

Do you have any models or drawings that you used or made?

I like the compressed air start method. Is it viable for larger turbines?
Hi,
Its the best method, to start a jet engine but you need a compressor, or an air tank. (Scuba tank)

Gana gut! Danke!
The afterburner is awesome 8:08 ,but unfortunately it happend
Hi, your videos are great as always, may i know where do u order metal parts online? Thanks
Hi,
most things needed, I find on ebay and in household stores like IKEA.
Andy
Too much backpressure. Needs an adjustable nozzle
Wow

du nutzt einen zentrifugal kompressor oder ?
Hi,
ja, ist eins.
Andy
@@Praendy Alles klar vielen Dank ich hatte auch vor ein Turbojet zu bauen hattest du bei etwas bestimmten grosse probleme?

Bác để nại em 1 cái turbine lực đẩy khoảng 50 kg cũ cũng được bác ơi
Please, your blueprint, I want to build it to Please
Hi,
Check the AMT site.
There are no blueprints, only technical specs.
The turbine is built in the Netherlands.
Andy
Give it a afterburner on the big one
Hi,
Already done 😉

This can never be put into a model plane. There is no material suitable for the heat and at the same time light enough for toy planes. Its moot
Hi,
never say never😉
With a nice layer of cooling air, its no problem to install it on a rc plane.
Will see soon.
Andy
