Would you really need a muzzle brake on a rail gun?  There's a lot less forward momentum of gas.  It's basically just the gas the projectile is pushing in front of it.  Since there is no need to seal in propellant gasses, the barrel could actually be vented along its length.  There wouldn't have to be any gas recoil to speak of.

Of course, that's anal retentive scifi technical silliness.  It's a nice looking model.

That's a nice conversion, WMN! :)  Any chance it'll be official in the EW rules, :;): :cool:

Hehe, you're right of course. There's no reason to have the recoil pistons on the side of the barrel either :D
Basically I've just built the model in a way I thought looked cool. The railgun technology bit is more of an attempt to tie it into some of the tech available to the Royal Empire.

Thanks :D

Well you'd have to ask Tom about that :D However it is a fairly straightforward conversion so threre might be a chance I think. If nothing else as a house rule :)

Looks Great WMN !  She does look a bit like M47's muzzle brake !  I like the modeling concept and execution. I remember seeing a line of a dozen or so M47s at the Desert Training Center in '88. Unfortunatley they were being used for targets :(

As someone with working experience with such guns: Is there any particular reason for the rather unusual muzzlebreak on these tanks?
I mean: plenty of tanks have the more conventional style break but I've only ever recalled seeing them on tanks from the 60ies. Any particular reason why it was abandoned again?

its simple high power low technoligy gives that kind of muzzlebreaks it was becaus back then the amunition was bordelining the posible for technoligy

I can't remember which tank the speciel muzzle break reminds me of?

M 47?

The M48 also had a similar horizontal break.

Actually WMN your on safe ground with the recoil hydraulics.

To immensely oversimplify recoil is as much a function of muzzle energy as well as propellant gas. Removing the propellant  gases will drop the recoil and the barrel is also going to be heavier on a rail gun which will also reduce the recoil transmitted but it will still recoil a fair amount.

The last study I saw for a naval rail cannon to replace the 5" naval gun was projecting a 63mj muzzle energy and a 18" recoil for the rail gun versus the current 18mj and 30" recoil for the current mod of 5" gun in service with the US Navy.

That particular set of specs on the rail gun also requires an electrical input of about 30 megawatts as well. Not a power plant your going to be able put on something short of say... a super heavy tank.  :;):

Yep, the earlier versions of the M48 also had the horizonal muzzle brake too, as shown in the pic. ?As well as the M41. As duz and "H" mentioned ... The technology of the time required a high velocity for range and penetration. And at the time that is what they came up with to reduce the recoil and even the muzzle flash to a certain extent ... ?If you notice, many tanks today don't have muzzle brakes; designs and technology advances ... However, some Armies today still use the M47, M48 and M41 ... ?They still get the job done.  When the Turks invaded Cyprus, in '74, IIRC, they were using M48s against Cypriot T34/85s. The ARVN used the M41. The Lebanese Army is still using the M48. But it may be upgunned to the 105mm instead of the 90mm. ?So those old warhorses are still around.

I've just spent the last 2 hours reading this thread from start to finish - the sheer level of output, consistently high modelling and painting skills really have been exciting and inspiring!

I look forward to continued posts of more incredible work!

WMN - I love reading threads like this one. So inspiring and FULL of excellent, helpful ideas. Just makes you want to go straight out to the workshop and build something (then put it on the battlefield and blow it up! ?:D ).

That Chemical Plant kit is SO useful (have you done anymore work on the Titan repair facility yet? )... and I just realised that I have a couple of the polystyrene buildings spare aswell... :p

Great work mate.

Thanks guys :) I love reading about other people's stuff so sbmitting my own is the least I can do. If someone actually likes some of it and can use it as inspiration then all the better :D

Anyway here's a pic of my workbench as it looks right now. Trying to finish off some old projects really. My ambition is to have the entire Legio Metalica painted up at some point but progress is slow so I though I'd better get some work done. Thus 3 reavers, the warlord and two warhounds are in the works. IN the background the model for the "Steel Hammer" Imperator titan of Princeps Senioris and Grand Master of the Legio MEtalica Thaddeus Wilson. I might submit that model to the EpicComp if I can get it finished in time but I don't want to rush it either. IN the mean time I'll just practice painting red on the other titans :p :D
