Have you tried "run as administrator"?
I downloaded a new component and it is now running successfully

Re: Questions about pressure and flow rate

theoretically, A and B should use the same amount of fuel, so their calorific values should be the same. They use the same amount of fuel, but B generates higher pressure and will therefore outperform A by a considerable margin, because projectile acceleration will be greater. Edit: here is a compa...

Re: Questions about pressure and flow rate

Assuming that there are two combustion chambers A and B, the volume of A is twice that of B, and the initial pressure of B is twice that of A, then theoretically, A and B should use the same amount of fuel, so their calorific values should be the same. Then the question comes, which one, A and B, c...

Re: Questions about pressure and flow rate

To put it another way: If your cannon does not inject additional fuel and air, but only compresses the mixture at normal atmospheric pressure, will its performance change?

You can use my mother-in-law as a target... JOKE! :twisted: What I'm dying to know is if the whole concept will work well. In my opinion YES! she will do it.
I agree

Re: A brand-new ignition method

Looking good! I assume that in the interest of safety you've made sure that all the pipes and fittings are rated for the expected pressures after ignition ;) I note that while the paper you shared concluded that "When the volume of the initiation end is larger than that of the booster end, you can ...

Re: Is there a more active website than this?

I think the fact that this forum is slightly active at all is because it's more or less the only such forum left, at least in the Anglosphere. There is also the Francophone "Patator" forum that used to be very active but it's even more quiet now, there is a post from more than 5 years ago lamenting...

Re: A brand-new ignition method

I would like to focus the conversation on the possibility of turning on a high pressure chamber with a lower pressure one, which is the subject of your publication. what you explain about increasing the pressure with two connected chambers, I know well, because I have already talked about it here. ...

Is there a more active website than this?

I think I'm late. Most of the posts were made 15 years ago. I missed the most active period of the forum. Is there a more active forum now? Or a telegraph group or something?
