Effect of beam weapon on electrical system

Post by False Prophet » Fri Sep 08, 2017 8:10 am

A beam saber can generate several thousands degree Celsius. That much heat can melt down any circuitry and wiring system in split seconds. But we have seen MS which has been stabbed several times and still able to wobbly around. How did they make the MS damage-resistant like that?

The sabre part isn't very dense.

Yes, it is probably several dozen thousands degree, but the density is low and thus the energy carried by it isn't that great. The power consumption of the beam sabres are much lower than beam rifles.

Also, you need time to transfer the heat, if you pull the sabre away too fast or the slashing action is too fast, the heat don't have time to transfer to the target.
Just like if someone wave their hand over a candle fire fast enough, there's little to no damage, but if you place it on top for even a second, you'd get burnt.

They needed the melee part for reenacting the samurai/knight duel tension and for audiences who don't know what a gun is(kids actually have to learn during the show how a gun works if they didn't have that knowledge before)
and games have to make the melee attacks super powerful so they are not useless.
But in reality, they should suck very much.

The beam saber is not a coherent blade, as such... unless its i-field encounters another i-field, it's basically a Minovsky blowtorch. Mobile Suits are made from some impressively heat-resistant ceramic composites, which would be tough to burn completely through in a large area. Consequently, a stabbed mobile suit doesn't have the heat from the damaged area radiate very far outside the damaged area.

Plus, the control bus and power distribution bus are almost certainly equipped with redundancies... even cars have fault tolerant control networks.

How is the innards of a MS is cooled anyway (especially the fusion reactor)? There are heat sinks (as seen in the F91), but what about liquid or gas cooling systems?

Regarding the matter of heat transfer, then yeah, you guys are probably right. The damage of heat is probably negligible in the case of beam sabers. A continuous beam, however... Remember the Leo that explode without being hit?

But what if something like, say, the Gouf whip, managed to penetrate through an MS armor, can the electrical system still be fried?

They implied there is a cooling system that pump the heat towards the surface of the armour. (This is where the scene in 0080 comes from, when Al tried to touch the Zaku FZ and its still steaming hot)
They didn't say it is liquid cooling or what, but the RX-78 does have coolant spraying out as part of its atmospheric reentry system.
The nuclear launching models like the MS-06C and RX-78GP02A does specifically stated they have liquid cooling systems under their armour(and shield in the GP02A case) which introduced the confusion as to whether they are uniquely so or what. The 06F modification kinda implied the liquid cooling was removed to lower its mass. Maybe it's only partly removed (because the liquid was also used as a radiation shield for the nuclear war, as the 06F doesn't need to protect from such)

There are great big heat exchangers on the front of every Feddie mobile suit, and IIRC they're fed by a liquid cooling system.

That's more indicative of the power of the Wing Zero's beam rifle than anything, though OZ mobile suits explode like they're made out of party snaps if someone so much as sneezes in their direction.

Eh, I dunno... it'd really have to be an extraordinarily precise hit to the onboard computers. Otherwise, there ought to be circuit breakers in place to prevent overvoltage and overcurrent conditions.

A fun thing is, in 08th MS Team, the Gouf B-3 somehow did managed to damage the Gundam Ground type enough so Shiro needed to change the computer board in mid combat.

Granted, if the current is strong enough, it may damage the circuit before the circuit breaker can do anything, but that scene still makes little sense.

Oh well, the Apsaras III was still using AMD-K6, DirectX SDK and FATA-2...

Well, the electrical shock function of the heat rod is meant to damage internal components and stun the pilot as noted on the archived Gundam Official website. Damaging electrical components is also noted in the capabilities of the prototype heat rod used by the Origin's Prototype Gouf.

True. But as E08 pointed out, he did so using a weapon that was explicitly designed to do exactly that via application of an electrical current.
It's not quite the same as the question of whether using what amounts to a sword-sized plasma blowtorch could plausibly cause that kind of effect.

Unless they're being piloted by Treize or one of the Killer Pretty Boys. :lol:

That said, there are a handful of other examples of similar incidents happening. I clearly remember in Unicorn for instance, one of the Sleeves mooks was narrowly missed by the Unicorn's beam magnum, and still went boom.
But yeah, I agree that it's probably more indicative of just how powerful the weapons in question are than anything else. Because you don't see that happen very often, and when it does, it's usually being done by a weapon specifically noted in the setting for its high power.

Not to mention, in Victory Gundam (second to last episode, I think), when the Victory Gundam Assault-Buster fires its mega beam rifle, we see several immediate mobile suits get destroyed, and, IIRC I counted at least nine explosions total, with the last few being in the distance beyond those immediate mobile suits.

In terms of Wing Gundam's buster rifle, I think the explanation given was something about the air getting ionized or something, I don't remember all the science jargon, lol. :lol:
