Hybrid ThorJack

[POLAND_SPUD]

I saw them somewhere and I thought 'damn these would be useful for an ignition module when I eventually get round to building my own hybrid in 2073'

Damn I wish it was as easy as you say - don't worry now I have some spare time but my fridge compressor has broken down... guess I need to find a new one and spend some extra $$$ on it

[jackssmirkingrevenge]

shock pump and syringe don't need that much $$$

[Petitlu]

with a syringe, you can make big Mix?

with a syringe, you can make big Mix?

In your case with a 200mL chamber, you will need to put 7mL in the chamber per mix. This means that 10x needs a 70mL injection, so you need a pretty big syringe

You can go up to 28x with this method, and for that number you don't even need a syringe - simply purge the chamber with fuel at atmospheric pressure, then pressurise it with air to 27 bar.

[Petitlu]

ok
A28x is the volume of the chamber, but to purge the air I need to put the BP in the long time chamber without bursting disc and then close all right?

[jackssmirkingrevenge]

That's basically it. Connect fuel supply, purge, close off supply, add burst disk, pressurise to 27 bar, boom

[Petitlu]

I love the boom!
Thank

I have not been able to test Mix20 today because of bad weather.
I'll do it tomorrow

How did you measured the effective chamber volume so precisely??
I always had mix problems that´s why I´m sticking with pneumatics together with my fridge compressor

[Petitlu]

I measured with water!
the room and I meter goes like this:
weigh the whole Chamber + + flexible connector (which will contain all of the air) with an accurate scale (0.1g)
fill with water and weigh all again, the difference in weight gives the cc

the electrode :

I don´t quite understand how the electrode works... Does the spark happens between the pin and the chamber wall?
I was thinking about fill the chamber with water using a big syringe, will it work?

[Petitlu]

I used a syringe to put water to be precise !

the spark occurs between the copper wire (blue) and the fitting which is screwed into the chamber

[wyz2285]

Ah I though so, Thanks Petitlu!
So, time for me to build hybrid

[Petitlu]

You made we a Mix80! 4" caliber !

[wyz2285]

Then I´m going to launch myself to the moon

[Petitlu]

In France they say "I'll get the moon" when you are ready to do anything!
