That's a great design1 Are those M2 Browning MGs?

I think the guy with the raised fist is saying "Я пукнул! Я признаюсь!"

You git I almost sprayed tea all over the screens when I translated that :)
What makes it more funny it that he is a she. The title of the image is "Ura" which is a Russian battle cry .... I hope.

The MG's on the side are pretty non specific and to be honest whenever I do an MG they nearly always look like a Browning.
Its not that its not real but it could be that its not true.

I'm not at all sure you care, however...

One issue with these sorts of mechs, including the Star Wars AT-ST, is that they actually can't walk, at least not as depicted. They aren't balanced correctly to allow the wide stance of the legs to manage the balance of the vehicle when perched on one leg while the other leg advances. The human body manages this by having the distance between the hip joints and the centre of mass be a small fraction of the length of the leg, that small offset of the joint meaning that the moment arm between the body's centre of mass and the vertical position of one foot is small meaning that the torque looking to pitch the body off to one side is also small. The body starts to pitch over, nonetheless, but with a small torque, it doesn't do so very quickly and then the other foot touches the ground and balance is restored until the other foot leaves the ground and the process reverses. This provides the rolling gait of a normal human walk. When running, when the downward forces are greater due to the higher vertical accelerations experienced, you notice that people's feet start to hit the ground ever closer to the body centreline, reducing the moment arm further and, again, we don't pitch over.

These mechs, pretty much all of them, have wide spread hips and relatively short legs and move those legs relatively slowly. By the time one leg manages to lift, advance and return to contact, the mech will have angled over considerably. The only gait that works for these mechs (as depicted virtually everywhere) is the rather hopping gait of someone walking on two older style prosthetic legs. They have to virtually hop their mass up as their legs move between steps to prevent tipping over and the usual pattern mech would have to be at least as bad or worse as the legs get shorter and the hips further apart.

To remain upright in your tech world probably requires some sort of lift generator to offset the toppling torque such that the mech would remain upright. Note, of course, that this also means that the traction on the legs gets less as the weight is offset, so it might want to be a variable lift force and maybe something coupled to the walking control system to provide for the right amount of weight offset depending on what the mech is doing.

If you don't want to do that, then with the usual wider hips and short legs you probably need foot pads that cross over the centreline of the vehicle, like some of the old, win-up, tin toy robots.

But, like I say, this may be faaaaar too much engineering thought being put into this. All I can plead is that I'm an aerospace engineer and I can't help m'self.

I love the feedback and believe me I wrestle all the time with this sort of thing.
You are of course totally correct and to be honest I have never been happy with mechs largely for those very reasons. I  also think that the development  may never have taken place in my universe but I had this half finished mech idea I started about 3 years ago and it was one of those scrap it or finish decisions.
The Russians did away with their mechs anyway as alternatives like the Solokov Volkosob which is much more in keeping with my universe.which I could post if you like.


You have described what I instinctively felt was a problem for walking mechs for a long time. I'm glade someone was able to finally explain it properly.


I like the look of mechs I must admit but the tech required to keep them upright. balanced and under control seems even more crazy than the crap I come up with.
Quads just look wrong to me  .. Star Wars ATAT for instance and Spider types too leave me cold as do the real ones. Tripods as per WoW can look pretty awesome.

I have only ever done one other mech thing which is called Steel Raptor

I remember reading somewhere that Volkosob is Russian term for a wolf hybrid breed bred by the Russian military to protect the borders.
Oh, the Wolfdog - I didn't know the Russian name of that beast. :smiley:

I guess it was the Bf 219. ??? The one you have shown at the ATF: two engines, 4-guns nose, yellow cowlings.

I found the shop too.
Its nice of you to say but I'm not sure my stuff would fit in.

As for the scale I not sure either. Technically its an AFV but it does sort of fly .. maybe 1/41.5 scale  just to average it :)
Well, the scale decision is usually the site owner's call, Mike Fitchenmeyer (I think it's spelled), and he would also ultimately make the call as to whether it "fit" or not into his stable of products. But, to my eye, it would certainly compliment the various styles he has produced.

If you were interested, you could easily submit your designs to him., The worst he can say is "no". And he might say "da".

What ever happens Iím going to save those pics and see if I can gather enough parts to attempt to build this if you donít mind. It would probably be 1/35 because of the number of tank parts required. Would the main gun be from an early model T-34?

I would have to commit time and effort which could be fun at first and then it may bug the hell out of me.

I have no probs with my stuff being used as long as I get a credit for the design and/or a pointer to the orginal concept.
I think it would be great if you did so please go ahead. I have some other non textured renders that might help too. The cannon was not based on anything in particular and a T34 would be ideal I would say.

The story of the North American P551 and its later transformation into perhaps the most outstanding fighter aircraft of WW2  is well known. However, often forgotten is the story of the contra spool arrangement or "dual spool" as it was known in the service.
 
The D model took advantage of the latest Tesla-Royce Merlin Electric, the TRM61, the power output of which was staggering and currently being used on early RAF Ion thrust hybrid  bomber aircraft. NA, working in conjunction with Aero Electric in the UK,were interested in expanding the field generation capabilities in order to increase the range the of Five-Fiftyone.  The type already possessed a useful range but even more was being asked for  which drop tanks and increased internal fuel capacity could not provide. However,  experiments carried out in England with double field  coil spools seemed to offer the solution.

It was found that by sliding a contra rotating  spool inside a parent spool generated a greatly expanded field. Having the master spools of both winglets spinning in opposite directions expanded both fields to a point where the normal figure of eight field expanded to a super ellipse. It was extremely power hungry but now with the TR Merlin Electric TRM61 it was possible to do so. Additionally, and much appreciated by future D variant pilots, the inner spools could be shut down requiring much less energy and so emergency capacitor power could be used if required.

The field enveloped the whole winglet area and the fuselage mid section smoothing vortices and reducing drag as well as generating lift. This reduction gave a  significant increase in fuel economy and therefore the increased range that had been called for. The increased weight of the spool assemblies was offset by an ingenious spool intake and exhaust system making full use of the Meredith effect.

D Models were initially prioritised for escort services in the Pacific attached to the B229 super heavy groups which until recently had been largely unmolested by the Japanese. However, a special detachment group of B229 was formed in England in early 1944 for  "wipe out raids" against known German vengeance and so called miracle weapon manufacturing sites. 



Even though air superiority had swung in to the allies favour after "the big week" of February 1944, there was still a real danger to the B229 in Europe in the shape of the ageing but still very effective ME626 flak fighter.  Proximity fuse development meant that the ME626 could stand off further and worry less about accuracy.  In addition they could stay outside of the target ground flak zone and fire into the bomber stream causing high casualties amongst aircraft committed to a bombing run.

The trick was to learn the patterns of attack they used and see them as they got into position. High level raids  helped as tell tale contrails often gave them away and the escorting fighters could go in pursuit. However, there was a rumour that the Germans were using some kind of exhaust gas cooling equipment that almost stopped contrail creation by the ME626.

So it came about that almost as important as a potent long range fighter was a pair of long range eyes balls.  One such pair of eyes belonged to Major James Peterson  whose incredible eyesight would become legend.  On July 24th 1944, Peterson was leading the 357th FS on B229 escort. He knew they were being stalked, he could feel it.  Now all he  had to do was spot them. 

He scanned sky again calling up the squadron as he did so saying " keep 'em peeled guys the bastards are out there somewhere I can smell 'em". And that is exactly what each pilot of the 357th FS did  as time without number they had survived and gained the upper hand and all thanks to Peterson's peepers.



Duxford is home to an airworthy P551 owned by the fighter collection. Disappointingly  the TFC P551D “Sue says hi” had to be towed away after developing what turned out to be  quite a serious field coil issue during ground running on the Friday before the Duxford Flying Legends display.  This was a disappointment for many hoping to take pictures of her over the weekend.  I was lucky to be in the right place at the right time to grab this image.



There is also a static example of the B229 at Duxford American air force museum. After making a 7000 mile journey, B229A Behemoth makes her final touch down at Duxford on 2nd March 1980. I was there too and the sound of the B229 is something you never forget. Under the turbocharged muted throb of the 6x super wasp radials there is an almost eerie howl from the Ion thrust tunnels.



Sorry for the state of the photograph but it is nearly 40 years old.
Note in the foreground the novelty retro aerofoil lifting surface types were quite the trend in the late 70's/early 80's. Cheap to build and run too.

I'll gladly credit your work, as soon as I get around to building it. So many ideas, so little time!

While the corpse of his double lay still smouldering in the Reich Chancellery garden, a surprisingly spritely Adolf Hitler was being prepared for his coming space flight.  His ship, an A16 Mondrakete, was ready for gantry retraction and lift off once the Fuhrer and crew were onboard.

Germany had made swift progress with Ion propulsion engines and the A16 had 4 of their most powerful to date but still she would need a last kick from a chemical rocket to achieve escape velocity.
 
No one would ever  know  if the Slavic slave worker team responsible for the mixture control assembly used unhardened taper valve pins on purpose or not but  it was effective sabotage. The assembly would work faultlessly under inspection and perhaps for one or two  low power ground runs but under load they would fail.

They say the explosion  was spectacular and oddly beautiful.
