Discussion on the best fuel type.

Not advised.

[Bhuvan Aerospace]

YA I know that but can I use that with extreme difficulties?

[racket]

YES , but don't complain when it fails

[Bhuvan Aerospace]

No, I will not complain but is there any possibilities to explode?

[racket]

Why do you think I answered "NOT ADVISED"

[Bhuvan Aerospace]

Ya I understood but I am getting feared a bit as I am using 2kg gas cylinder with my sucking tin combustion chamber.

Here' s my advice: If you dont have access to the required material, tools and dont have any idea about what to do just stay away from that kind of project.
Take a break, let your mind clear up and focus on some other project within your capabilities.

[Bhuvan Aerospace]

I have idea, tools but lack of material. Let's see what happens tomorrow because tomorrow I will test the engine with tin combustion chamber and propane gas cylinder.

[Bhuvan Aerospace]

Can I use piezoelectric gas lighter (like one which I have attached here) for igniting the gas inside the combustion chamber? Because I have Spark Plug but I don't have Ignition Coil as it is not available in our area.

[racket]

Easier to ignite the gas at the turbo exit otherwise you need to seal the piezo

[Bhuvan Aerospace]

I think piezo remains at the middle of the lighter. So I will only put the outermost portion of the lighter inside the combustion chamber. Is that okay?

[racket]

LOL.......I really don't know why you ask for advice when you go ahead and not take it.

How are you going to seal the piezo so that the air/gases within the flametube don't leak out , also is the end of the lighter able to cope with the intense temperatures within the flametube of >1000 deg C .

[Bhuvan Aerospace]

Yes you are right. I have to search more for ignition coil.

[racket]

No , just ignite the gas at the outlet of the turbine wheel , the flame will retract inside .

How are you rotating the rotor to start the engine ??

[Bhuvan Aerospace]

With airblower
