gun stabilization

Post by monster » Wed Apr 23, 2008 1:18 am

Hi guys,

Does anyone know if anyone and built or bought gun stabilization for their main gun in a 1:8 or 1:6 tank?

Do you reckon you could use a helicopter gyro?

Cheers

Hi Sean,

Yes I believe there are some who have done this using a submarine leveller, this is a similar idea to a gyro I guess but is used in R/C subs to keep them level when underwater.
In fact, I have just recently bought one which I intend to try in my 1/6 CR2 which I am currently overhauling.

you can get lateral and vertical stabilisation but the subleveller is a little bit sensitive, I believe someone got the maker to lower the sensitivity a bit. I tried it on the T90 it did work but tended to vibrate the barrel up & down on gravelly surfaces, it was very good when going across undulating ground. the lateral was taken care of by a GY502 avcs gyro this again worked but my turret turn motor isn't fast enough, the turret turn speed needs to be adjusted to the gyro the chally will prob be better as it has a faster turret turn...george..

Having tried both sub levelers and heli gyros we cam to the conclusion that they are useless for gun stab. My Chieftain has full stab/trav stab and off from a home made module, this is programmed to the tank on a PC so all parameters can be set/adjusted. my friend has also included full turret trav stab via a stepper motor and another computer. These are his own design but when in use replicate the real thing 100%, something you will not get with the other systems. Being a 1/1 user i can assure you therse are accurate. :D

I've seen a 1/6 scale Leopard in Germany who uses a laser beam and some electronic stuff to stabilize the gun to one set point. Just like the real thing ....

Just curious...DID the real Tiger 1/ KT's barrels bounces while moving cross country?

Gabriel,

Certainly from old film it seems that Tiger, KT, panther etc did 'suffer' from barrel bounce. I believe that the instructions for a JagTiger was that they must fit the barrel lock before 'marching' otherwise it could damage the gun mounts.
I haven't seen these running for real, but have it on good authority that the running 1:1's exhibit the same symptom.

Hi,

Get in contact with Bulldog, he has a stabilization unit in his 1/6th Challey, but dont know about his Leopard.

Cheers

All main guns in tanks go up and down when traveling across country the bigger the gun the worse this is, only if the gun is in the travel lock will this not happen Tiger I and Tiger II had an internal travel lock so if you see film of a Tiger without any bounce in the gun it's got the travel lock secured

Hi Rivet,

Modern stuff of course has automatic stabilisation but your answer makes sense for the observed Tiger I/II behaviour. Do you know if their 'internal travel lock' locked at a fixed position, e.g. horizontal, or at any chosen elevation ??

John, not looked at this section for a while, very good question I will have a look through my books and see what I can find out but I suspect that the gun was at an elevation, Centurion had a similar system where the gun was elevated but this was not adjustable

Hey John just looked through my book "Germany's Tiger Tanks Vol II - VK45.02 to TIGER II" and in one of its sections...there is a travel lock inside the KT's turret ... it's welded to the roof of the turret and would be lowered and "lock" the gun while travelling.

Bringing to life an old topic, but has anyone progressed with gyros and sub levellers for the main gun and turret turn?
