FIRST IDEA: ___________________________________ Dear Larry, delivering the exhaust gases of a turbocharger based turbojet engine to the "diffuser" of a ramejt is not surely called an "afterburner". I know you have come up with the same misunderstanding most of the people do when I talk about this id...

I have an idea i want to share it with you: What if we deliver the exhaust gases of a turbojet (turbocharge based turbojet) to the diffuser of the ramjet? is it possible to use the exhaust gases of the ramjet to spin the turbo turbine and then deliver the compressed air(coming from the turbo's comp)...

still no replies :(

Thanks my friend, you're right. this MONSTER needs two blowers instead of one to work. I'll be after that, and I'll inform you about any step forward in my work.

Thanks,

Arman.

Hello All, I wanna build a turbojet engine based on a car turbo, I wanna use the smallest possible turbo to make the engine as samll as possible. What kind of turbocharger do you offer? What compression ratio does a turbocharger produce? ________________________________________________ The most impo...

Thanks for your replies, the reason for not firing the engine up was that I haven't found a really powerful leaf blower yet.
as soon as I find a good and reliable leaf blower (supplying the airflow at it's max power) I'll fire that Dragon(!) up!

No one interested really???

any ideas are apriciated..

Here is some pics of the "Monster" I've made:

Hi, I'm now right back!

The nozzle flanges have been successfully constructed and now, the engine is complete and I've managed to test the engine by the next week.

I'll post some pics of the "NICEST HOME-MADE RAMJET EVER!" soon.

Thanks,

Arman

Dear Larry, Thanks a lot, You've clerified almost everything for me about the ramjets.

I have another idea about motor-jets. The idea is under Construction! as soon as I get to a logical result, I'll share it with you.

Again, Thanks for everything...

Waiting for your repiles... :D

What's your idea about delivering precompressed air to the engine? is it possible? How does this affect the engine's total thrust?

OK, for this diffuser area ratio, How fast does the air have to travel in order for the engine to be at "self-sustain" condition? What's your idea about delivering a pre-comressed air to the engine? will the engine produce much more thrust? Is the flame holder I showed a pic of suitable for my engine?

Hi, I'm Arman, I haven't been here for a while and now I'm back here with you. If you remember me, you will probably know I have been on a ramjet project which I've talked about extensivly on the "A question about home-made ramjets..." topic. By now, I have made almost all parts of my ramjet and as ...

Dear Najm, I've successfully made a very nice nozzle cone, it looks really beautiful and I'm quite happy I could have machined that, after a long period. Now, the only remaining parts waiting to be made are two flanges that are supposed to be welded to the nozzle and the CC. Then coupling of the noz...

I wanna go for testing, but I've got really big problems making the nozzle. You know constructing the nozzle which is actually a cone is difficult, cuz I can't machine it from a solid piece of metal, so the only way is to get something which it resembles a cone and then machine that, I really don't ...
