Baffle design idea (3D printed)
How does this baffle design look? I’m thinking the vanes would take energy out of the air by spinning it. At first i was going to make my shroud with internals like the Weirauch/Hogan/Hugget with two discs and some open cell material wrapped around a vented central cylinder (the red part in the shroud assembly pic). These designs are well liked in the UK. My shroud is for a 5fpe Steyr LP that also has 3 flip reducing upward vents behind the muzzle. But then I thought simple might be better using M baffles printed as one piece with the shroud. But I still liked the open cell material idea … then i thought of vanes to dissipate energy by changing the direction of the flow and looked at some turbo impellers and went from there. The vanes have RH twist and end before the OD to allow circulation of the air.
Thoughts? Criticisms?

Thanks!
The 3 pieces in the shroud assembly are about $70 printed by Shapeways. If all three were integrated as one piece it would probably cost around $65.
The muzzle vents into the first chamber between the grey perforated disc and the red conical disc. The perforations allow the air to flow into the shroud which is vented all the way back into the blue shroud mount. The blue shroud mount has 4 small holes venting to the atmosphere. The blue mount is a separate piece so some open cell material, like a used scotch brite pad can be slid into the grey shroud which will dampen the air coming back from the muzzle and also the air coming out the three anti-flip vents in the top of the barrel behind the muzzle.
Looks cool, But I am no expert by a long shot,
What would something like that cost to make a run of them,
I do no if there is to much back pressure on the pellet leaving the barrel, Its going to throw pellets everywhere…
If you have the means the knowhow and the stuff to test with you may set the new standard for air gun LCDs.
I say do it,

So when can we see the new baffle on the market? All your designs sound great, But I think its going to be up to the pellet,
