have you considered crimping the copper tube?the "projectile seal" idea
That's the crux of the matter, but with a bit of lateral thinking...POLAND_SPUD wrote:flying brass is cool... but in order for this to be practical you need to focus on making the cartridges as simple to produce as possible
Hmmm... metal on metal won't guarantee a seal and it's not really reusable. I can easily envisage casting epoxy around a section of rubber or silicon tubing though.have you considered crimping the copper tube?
I don't doubt that flying brass is cool, but when said brass is something that takes a lot of time and effort to prepare, it's less desirable to be spraying it everywhere.jackssmirkingrevenge wrote:Valid points, however on the plus side...
The problem in my opinion is what happens if the fuel that will have no doubt leaked into the pilot volume gets ignited. With piston hybrids, the "pilot area" has to be kept vented to atmosphere.jackssmirkingrevenge wrote:The problem though in my opinion would be guaranteeing a correct fuel-air mix in the chamber.
well yeah there is nothing else than just the coolness factor...it does seem like a more plausible way of achieving sustained fire
I really doubt cartridges would be lost or damaged, and once manufactured filling them should not be that much of a hassle.Ragnarok wrote:I don't doubt that flying brass is cool, but when said brass is something that takes a lot of time and effort to prepare, it's less desirable to be spraying it everywhere.
That's the BBMG approach, with the power potential of a hybrind you can do more with lessAlso, while you can do some serious damage to a target with 5 to 10 rounds, you can do a lot more damage than that with more - even potentially to the point of cutting things in half.
Sustained (10 second bursts, that sort of thing) fire would be out of the question with homemade cartridges, if this is one of the design objectives then an on board fuel-air system is the way to go.Not that I'm saying that the way I propose is the only way to go about it, but it does seem like a more plausible way of achieving sustained fire.
Details that can be worked on, as I proposed the projectile-seal approach is probably better.The problem in my opinion is what happens if the fuel that will have no doubt leaked into the pilot volume gets ignited. With piston hybrids, the "pilot area" has to be kept vented to atmosphere.
Also, that particular design runs the risk of sparking on the outside of the cartridge (uselessly, of course).
You have to factor in the weight of compressed air and fuel tanks which a cartridge launcher avoids.for the number of shots typical for a full auto/semi auto gun cartridges + launcher will weight more than launcher + projectiles...
