Ulric Posted February 24, 2015 Report Share Posted February 24, 2015 So, a bit of a technical question because I am too lazy to do the maths involved (and also, the maths are a bitch, depending on how deep you want to dig into it): Is there an acceptable or optimal ratio between gas port diameter and piston face area, or is gas port diameter the only thing we really care about (obviously in relation to its distance from the chamber). Basically, I am trying to understand the finer points of gas flowing through a constriction and back into a larger volume of space in the context of gas operated rifles.

Sturgeon Posted February 24, 2015 Report Share Posted February 24, 2015 I don't know if there's a hard and fast relationship to ensure good functioning, but there definitely is a relationship between gas port diameter and piston diameter. Wider piston face means more area for the gas pressure to act on the bolt carrier, and wider gas port means more gas allowed into the gas block, so widen either and you increase the amount of force acting on the bolt carrier.

Ulric Posted February 24, 2015 Report Share Posted February 24, 2015 Im just trying to figure out what the pressure in the gas cylinder would be for given port size and pressure at the port. Am I making it more complicated than it is, or is it a rather complex calculation? Quote Link to comment Share on other sites More sharing options...
Sturgeon Posted February 25, 2015 Report Share Posted February 25, 2015 More complex. It depends on the shape, as well as diameter, of the gas port, as well as the characteristics of the propellant. It's a fluid dynamics problem, basically. Quote Link to comment Share on other sites More sharing options...
Ulric Posted February 25, 2015 Report Share Posted February 25, 2015 That is what I was worried about. I guess I really should go for that BSME after all. Or the other option is to get quite a bit of rather expensive testing gear and gather a bunch of data on this. Either way this is not going to be cheap.

Ulric Posted February 27, 2015 Report Share Posted February 27, 2015 M53, and yes, it would appear to be so. I don't know if there are any visible external differences between the MG 42 and the M53, but I do know that the M53 has a reduced ROF. It's just a shame that the M4 isn't the Yugo D-25T refit.

Khand-e Posted February 27, 2015 Author Report Share Posted February 27, 2015 So, Popenker did an article on shooting knives, I actually did email him asking if he'd consider doing one, though, considering he doesn't know who I am I'm not sure how much, if any influence that actually had on him deciding to do so.
