It's a shperic form, go see the diagram in the first step of on shell. ^^ Yes I will need a mixture of at least 2 or 3 to start.

what is the thickness of a burst disc in general?

I did some tests on solidworks but I find them bad ...

To know the approximate necessary force at which its rupture disc breaks, you must assemble the disc inside the system and with a rod of the same diameter as the area exposed to the explosion pressure, gradually tighten and measure the force with a balance. So you can determine at what force it bre...

What is the volume of your chamber?

I have 1216,5ml for my combustion chamber

I have the results of my calculs for the power. However I ask a question, in the simulator, I put a tensile strength of 10 bar on theburst disc. How to obtain these 10 bar of resistance by adding layers of aluminum foil and by doing tests or can we determine the thickness by calculs ? :D these resul...

i think a warehead shell is the best form more than spheric one .. the weak power of the weapon and its range comapre to the real one I do not think necessary to use grooves. In addition, the machining of these guns is hell for an individual I have some projectile design for my pak36 like: I think I...

So tels me what is the rôle of rifling in the brenneke rounds ? It is for stability or something ? So its complicated to give a spin on a rounds ? I have no idea ^^ By night with tracer round i love it. I have an idea paint the round with phosphorescent paint. Maybe at night it works. Go for lot of ...

and make tracing rounds ! i thinks is not necessary. it's too complicated for a good results. I thought of vortex nerf rocket. I seem afraid of losing performance.
you have already tried to make rounds spinning inside the barrel with a smooth barrel like maybe .12 brenneke shell into a shotgun

good, now we have to draw rounds and make them whistle while passing !! xD

in real life I'm sure it's possible to do it ^^

AMAZING VIDEO !!! Poor soviet T26.... ^^

I will do the calculs at the evening, I will see if it is good. I send to you the resuslt to have a second check with people more competent than me

At this stage of the design, I have almost finished the 3D design, I still have a little work to do for the mechanism, but otherwise it's almost finished ^^

let us admit that I use the principle of filling with the syringe how to calculate the quantity to be injected into the chamber as well as the compressed air and how to calculate the ratio? can we determine the force that the gun will have on the projectile, ie how many newtons will have to resist t...

Yes in addition to being realistic, the percussion system is reliable. I don't trust electricity ^^. On the other hand, the loading of gas by syringe is not stupid! on the other hand, it is necessary to create another hole to fill the combustion chamber or to use the Shrader valve is possible? becau...

I will use the same principle as in this video. mixing takes place directly inside the combustion chamber. https://www.youtube.com/watch?v=JPSjwxvINF0&ab_channel=PerformanceCannons Step 1 : I put the gas 2nd step : compressed air for the rest yes I have the rest I am finishing the design. The .22 bl...

Hi everyone I introduce myself. My name is Alexy, I come from France. I am a student in an engineering school and passionate about history of the WWII. I have a project that has been going on for several years : make the most realistic German WWII Pak 36. To do this, I made CAD to make a breech load...
