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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EP4Hf63zR6w.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!
@@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
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
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
