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 to...

Re: A brand-new ignition method

If in a closed chamber I manage to introduce propane and compressed air within the range of stoichiometric proportions, at 100 bar, with a proper ignition, will it explode? :? With the right ignition it should, and we have proof :) I don't know if you're aware of this example that was shooting at u...

I hope it is something simple the problem of your machine. Surely it is so.

Re: A brand-new ignition method

Why can't a compressed air-propane mixture burn at more than 28X? I didn't know this, and I don't understand why... It will burn at much higher mixes but if you are fueling with the propane at atmospheric pressure, then 28x is the highest mix you can achieve. If in a closed chamber I manage to intr...

Re: A brand-new ignition method

That sounds like it would work, but what sort of mix numbers are you thinking about? I was able to ignite mixes up to 16x using a simple piezo from a cigarette lighter, and about 28x (the highest you can go using just compressed air and not oxygen) with a high voltage stove ingitor . It seems like ...

Re: A brand-new ignition method

I am sure that what you propose will work well, it is an interesting solution. it must only be ensured that the intermediate rupture disc is destroyed at a pressure greater than the mixture pressure in the higher pressure combustion chamber. The practical limit is when the low pressure chamber needs...

Re: Is spudding dead?

I do not know. I have almost completely read the publication that Jack brought here on this topic, and I find it difficult to make this more than fun, for a few, the usual ones.

Re: Is spudding dead?

It is a good idea to organize an international support of built elements to make real, (noise and holes) a plane, generated right here, together with a prototype, which is surely built by those who have more tool possibilities than the rest. I imagine that users should be asked which of the projects...

Re: Is spudding dead?

perhaps going down the path of COOPERATION and not COMPETITION is more profitable. A simple project or a series of projects and not so much is the way to encourage participation. I mean, do it together. A chimera? perhaps, but surely it is trying to give it shape and viability. :)

oh yes, wielding the subjectivity of opinions and "analysis" is the first thing, especially when you think from the other side of the fucking planet! Cheers 8-)

Re: Is spudding dead?

There are a lot of people, hobbyists, who make their own stuff, from homemade PCP guns, to combustion springs, hybrids, and god knows how many more. It seems that only the scenario has changed, the forums for social networks. The hand above "I like it" is sometimes the only "affective" retribution o...

Re: Rapid Fire Hybrid System

Excellent, that's a lot of cans perforated! It's because it has more pressure... and therefore more fuel. Transfers 4 full cans safely, and at 11X, 5 1/2, from a short distance, about 6 meters. At 20 meters, it goes through 3 cans cleanly. I have not tried further, because it is very difficult to h...
