Checkout my email of the 11 Oct about spoolups , sounds like you are blowing the fuel away from the sparkplug.

Ya I saw that post but you told me to follow me this procedure when using piezo lighter not spark plug.

[racket]

A spark is a spark .......duh !!

LOL.......why do I try :-(

[Bhuvan Aerospace]

That means first I have to put the blower, then turn on the fuel and turn on the ignition, then remove the blower. Let the rpm to decay, then again reapply the blower. Isn’t it sir?

Here is an image of it:-

Turn the ignition on first before introducing fuel in the engine. That way you wont get a puddle of fuel accumulating in the engine before it ignites.

Can you share more pics of your engine?

[jetric]

That engine is not going to last very long with no oil system, also the tyre inner tube used for the compressor discharge will expand like a balloon but that will be ok because it will fly off first because of the twisted wire that's not holding it on. 😂😂

Let’s see what happens.

……..LOL……..THIS ENGINE SUCKS!!!!! WITH A TIN COMBUSTION CHAMBER!!!!

[Bhuvan Aerospace]

It is just a prototype engine for our main 1kN Turbofan Engine which is under construction.

Some images of the engine are here (nozzle not installed) :-

Hello. I don't know if this has been discussed here or in another thread. But if you use gaseous oxygen to start the engine, is it easier?.
Does it multiply the power by 5?.
What free power turbine would handle this?

[Bhuvan Aerospace]

Ya!! Using Gaseous oxygen is good only during ignition as it helps the fuel to ignite faster. It gives 3x more power not 5x. But it is risky if oxygen is used after ignition when the engine starts. It is because the fuel will burn more violently to pure oxygen causing more temperature and pressure inside the combustion chamber. If the combustion chamber is made out of thin and weak metals like Tin, it will get melted easily. So in conclusion, adding oxygen is safe only when igniting the fuel (I also have Oxygen Cylinder at my home so I am gonna use that).

[joescuti]

Ok. I was just saying that because air has 1/5 oxygen but based on your experience it may only give you 3 times more.

[Bhuvan Aerospace]

Yes sir. But I am thinking of using a bit oxygen. The oxygen pipe will be 60cm away from the compressor hole of the engine so that the engine receives 1/2 of the oxygen coming from the pipe as too much oxygen can make the combustion chamber explode!!

[Bhuvan Aerospace]

Cuz my previous combustion chamber exploded for this reason only!!

Good Night…

Oxygen? What are you making ? A bomb? You kids are gonna hurt yourself. Work on your fuel and ignition system instead No oxygen required. Bever heard of this.

If you can't make a conventional system work try again or just drop the whole project but keep oxygen away !
