If you get a chance look at the Heng Long tanks. they will run around ~$100 give or take and some people have made them up to just a crazy level of detail. I have a Pz III and did a quick once over with an air brush to weather and put a little snow on the tank....it did not come out too bad.
The link below is just amazing what someone did to one of these cheap tanks.
Nice concept. Works well for what it's made for. Nice, ultra low profile.
(this may have been covered previously)
I've often wondered and kinda assumed the bulge fat thing on tank gun barrels was a gas pressure release of some kind. Well, I just did a little googling and found the definitive answer.
It's a "bore evacuator"
What I didnt know, is it is to lessen the fumes from entering the crew cabin.
"A bore evacuator is a device on the gun barrel of an armoured fighting vehicle which helps prevent poisonous propellant gases from venting back into the vehicle's fighting compartment when the gun breech is opened to load another round"
any body got anything to add to this thread?
its been over year so I wondered?
I would have thought with how popular the World of Tanks thread this would have more activity.
Yep, and it's an extremely simple device too. All it really is, is a chamber that has ports angled towards the muzzle. The projo is fired, and as it passes the ports the propellant gasses are forced into the evacuator chamber. Once the projo is out the tube, the pressures start to equalize within the tube, to the point that the breech starts to open....right about then the extra volume of the equalizer chamber has started to purge itself towards the muzzle, and the gas flow pulls air from the breech end. Doesn't work perfectly, but it makes a huge difference between having and not having a bore evacuator.
I used to read that as a kid...
Maybe this thread slipped down the pages and the World of Tanks started after?
I am not in to that world of tanks, I dont play computer games, but I wonder if it evolves long enough if they will start to get new tanks, Chieftan, M60, Leopard 1, T72 on to Challenger, Abrams, T80, Leopard 2, What about Flakpanzer Gepard?
As it is WoT is very UN-realistic...it is a game not a sim. With history as our guide there would be no point in using eastern tanks. Fire control, optics, survivalability is just so much better on Challenger/Abrams over the soviet tanks it is not funny. It really showed their thoughts on tank design....quantity has a quality of its own, and there is always 4 more to replace the one you lost.
I almost quit the game as it drove me insane...but now I just drive around and shoot stuff....it is a good way to end the day after dealing with idiots all day long.
youve got to look at them in their timeslot, the later model shown in the pic was only really used by recce units and a wheeled armoured car does a better cheaper job.
but in '41/'42 when the early models were supplied to us by the states, and used in the western desert, they were comparable to anything else, italian bean tins mostly. the main gun was about as good as it got, dont forget nobody had figured a large exploding shell made a bigger mess of a tank than a weedy 2lb solid slug till rommel came along with his 88's. we called them "honey"s because they were comfortable, reliable, easy to work on and easy to live with.
Evolution. There was this one then some one came along with better and bigger. I guess the gun logic was to get the first shot in. a 2lb at a longer range, get them immobilised.
They where pretty good little tanks....and gave the brits something their 2lb guns did not give them.....HE. Also at the time it was on par with the 2lb and the short 37 and even the short 50 the germans had...it was not till the long 50 came along that the shells really started moving and it was found out that long barrel guns made holes in tanks better than the short low vel. guns.....a fact that is lost on the game WoT.
Really a better tank than the PzII and on par with brit armor at the time....Matilda had better armor but much slower.
Here are some pretty good videos....they have some on quite a few different tanks
more tracks, less wheels!
but its something to look at
got any more tracks
secound pic down is an Abbot from the UK on the Scopion / scimitar chassis family
one of the most enduring designs?
That turret is way too big. It's going to fall off the minute that tank gets moving.
