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?

Re: A brand-new ignition method

What is his method? I don't understand. Do you use electric heating wire to ignite? Using a hot wire doesn't really work well, I've tried this with an atmospheric combustion to make the point: https://youtu.be/OmLNm6Myg7s Compare the delay with a spark: https://www.youtube.com/watch?v=CyaMRqjAfKo W...

Re: A brand-new ignition method

I see it more practical to turn on, for example, a camera at 80X, use an intermediate disk that breaks at 100X, and a camera turned on at 15X, which I think will break the disk. It should generate about 120 bar, the ignition chamber. To make it practical, design engineering is needed. I am afraid t...

Re: A brand-new ignition method

I'm thinking of using 1mpa low mix to ignite 5mpa high mix. 5 mpa would be 50x, I haven't got any personal experience with it but I would say the wire method Larda used is a simpler way to go about it - you have to replace the wire every time, but it is easier than having to fill two separate chamb...

Re: Questions about mixing multiples

Firearms generate tens of thousands of psi of chamber pressure, so if you keep the same caliber and projectile weight, achieving similar power is impractical with a hybrid. https://i.imgur.com/32QQPsG.jpg Using a 50x mix and a 30 inch barrel with approximately 2:1 chamber:barrel volume ratio, I got...

I don't know if anyone has made a specific side by side comparison, but while the ratio of oxygen to propane is the same in both cases, there are important differences. Working with pure oxygen is a lot more dangerous so it is less practical, and there is a danger of DDT especially at higher mixes....

Re: Questions about mixing multiples

In fact, I have used 12 times of pure oxygen and propane to accelerate a steel ball with a diameter of 10.5mm and a weight of 5g to 575m/s. According to the kinetic energy formula, this steel ball carries 800j of energy, which has far exceeded the kinetic energy of a 9mm pistol, so I think it is pos...
