Given that in the game pilots apparently randomly fail their shutdown check I have always envisioned it as basically a dead man switch that they have to keep mashing to stop the reactor turning off and sometimes they forget.

quote:

43. During the action, power on fire control and interior communication circuits throughout the ship was lost for approximately three minutes as a result of short-circuits due to the destruction by gunfire of cable and
equipment on I.C. and F.C. circuits in the superstructure. The short-circuits produced an overload such that the circuit breaker on the normal feeder to the I.C. switchboard tripped on main generator and distribution switchboard No. 1. The I.C. switchboard was equipped with automatic bus transfer to shift the power supply to the emergency Diesel generator switchboard No. 1 in case of interruption of normal power from the main board. As the capacity of the Diesel generator was considerably smaller than the connected load on the I.C. switchboard, the F.C. and I.C. bus was energized through a 1000 ampere circuit breaker which was designed to automatically open before the automatic bus transfer operated. Thus, only the load on the I.C. restricted bus, which was well within the capacity of the emergency generator, would remain on the board. The circuit breaker opened properly. But after the automatic bus transfer operated, the fuzes protecting the emergency supply "blew." Apparently several of the circuits connected to the I.C. restricted bus were still short-circuited. Defective circuits were isolated and power restored on all serviceable I.C. and F.C. circuits in approximately three minutes.

44. Ordinarily, matters which are not the result of damage by enemy action are not included in damage reports. In this case, however, the fact that electrical failure initiated by the shock of gunfire was a handicap to SOUTH DAKOTA while in action warrants some comment. As a result of this failure, numerous control shifts had to be made and it was reported that all power on the after part of the ship was lost for about a minute. This occurred before receiving the first hit.

45. At the time of the failure, normal power was being supplied to the after 5-inch director from generator and distribution switchboard No. 4 through a bus transfer panel, power distribution panel, and an automatic bus transfer switch (PLATE II). The automatic bus transfer switch received its alternate supply from generator and distribution switchboard No. 2 through a bus transfer panel and a power distribution panel. The AQB circuit breakers in the distribution panels, which were in unattended locations, were "locked in" in accordance with outstanding instructions.

46. The shock produced by Turret III firing astern caused the contactor for the alternate power supply in the automatic bus transfer switch to close, thereby paralleling generator and distribution switchboards No. 4 and No. 2. As the two power sources were not in phase the resulting synchronizing current surge welded the contacts on the automatic bus transfer switch closed and the normal feeder cable to the after 5-inch director (FE834) ruptured and short-circuited between phases on the No. 4 generator and distribution switchboard side of the rupture. Because no mention was made of trouble on the alternate power supply to the director, it is inferred that the rupture of the normal feeder cleared the short-circuit on the alternate supply which then continued to supply the director. As the AQB circuit breaker in the power distribution panel was "locked in" the fault on generator and distribution switchboard No. 4 was cleared by the tripping of generator No. 7 ACB circuit breaker. It was not reported whether the feeder ACB circuit breaker tripped also but it was implied that it did.

--12--

47. The operator then energized generator and distribution switchboard No. 4 from generator and distribution switchboard No. 3 by closing the bus tie (FE0404) circuit breaker. The circuit breaker for the normal feeder (FE0716) to the bus transfer panel was closed manually, causing the circuit breaker to generator No. 6 to trip. At this time, the circuit breakers on both normal feeder (FE0716) and alternate feeder (FE0420) to the bus transfer panel were opened. Power was restored to generator and distribution switchboards Nos. 3 and 4 by closing the circuit breakers to generators Nos. 5 and 6. The alternate feeder (FE0420) circuit breaker to the bus transfer panel was closed at generator and distribution switchboard No. 3, tripping out circuit breakers for generators Nos. 5 and 6 and the alternate feeder (FE0420). Circuit breakers for generators Nos. 5, 6 and 7 were immediately closed again, while circuit breakers on normal feeder (FE0716) and alternate feeder (FE0420) remained open. From the time of closure of the automatic bus transfer switch until closure of the circuit breakers for generators Nos. 5, 6 and 7 it was reported that about one minute elapsed. Repair parties then located the fault, isolated it and restored power to 5-inch mounts Nos. 6 and 8.

48. The source of these electrical failures was the unreliable operation of the automatic bus transfer switch. All of these switches have been replaced by a manual type transfer switch.

49. The power interruption on the after main switchboards was made more extensive by the failure of the feeder and the main generator circuit breakers to operate selectively under short-circuit conditions. As a result, instead of the feeder breaker operating alone to isolate the short-circuit, the generator breaker also tripped out at the same time. For proper operation, the generator circuit breakers should not open under fault conditions except when the fault is on the switchboard bus or between the generator and the switchboard. This means that the generator circuit breaker should have sufficient time delay at currents equal to the maximum short-circuit current of the generator to permit the feeder breakers only to trip. At the same time, the generator breakers must provide a reasonable amount of switchboard bus fault protection. After considerable study and development and subsequent to this casualty, improved circuit breaker performance was obtained by replacing the time delay dashpot trip devices on the main generator circuit breakers with a type PQ relay. The type PQ relays installed on the SOUTH DAKOTA were the first that became available. Nearly comparable improvement in selective breaker operation has been obtained on similar ships by the installation of special time delay dashpots on the generator breakers.

If anybody (nobody) needs further context:

I.C. - Interior communications
F.C. - Fire Control
AQB - An airgap circuit breaker in a full shell molded plastic case installed in a distribution panel.
ACB - A larger airgap circuit breaker with an open shell frame, installed in their distribution switchboards by large sliding rails and jackscrews.

Since I happen to have one sitting in my pile - Here is a fully functional if slightly mangled AQB-400LF, which is 400A with (the slightly mangled part) a 100kA fusepack slot. Used for 200+ HP pumps.

tl;dr: Get good quality circuit breakers or you risk losing all power to your 45000 ton Battleship, including all sensors, fire control and communications.



That's what I imagine your 'Mech shutting down is like. Tripping the right breaker turns everything back on. This is of some consequence when engaging enemy capital ships at point blank range at night.

From that standpoint making heat do internal structure damage is a decent enough way to approximate that in a computer game where you pilot isn't independently tracked re: health.

Now, taking this full circle to the game that this thread is ostensibly about, I kind of wonder why they went with the internal structure damage option in HBS BT rather than making you roll to prevent your character taking damage. In vanilla BT I'll just shrug and deal with a couple points of internal structure damage in an assault or heavy. Oh no my Stalker alpha'd for the third turn in a row and took 8 damage to all its internal hit boxes, the horror. But if it straight up dealt a point of damage to the pilot? LMAO I need that rear end in a top hat in the cockpit for the next mission, time to get serious about heat management.

I'm impressed as hell that the Damage Control crews managed to isolate and fix that poo poo in 1 minute and 3 minutes respectively.

A few years back I had to dig into some poo poo on the USS Stark for job related stuff and ended up reading a bunch of accounts of the ship both before and after she was attacked. The tl;dr on that for anyone who doesn't know is that Stark was patrolling the Gulf during the Iran-Iraq war and got slammed by two anti-ship missiles. Came really loving close to sinking, heroic damage control is the only reason she didn't.

Anyways, it turns out the Captain (who got royally and unjustly hosed during the investigation I may add, and who by all accounts knew this was coming based on telling his officers to throw him under the bus if need be while the ship was still flooding) was a massive, hardcore, damage control nut. One of the things he would do is basically randomly grab crewmen in the halls, throw a bag over their heads, spin them in a circle, and shout at them to get to their damage control station. He wanted everyone to be able to find their spot in the dark, when disoriented.

More than once in the book I had you find some seaman saying "yeah that was annoying as piss and we thought he was insane but then the missiles knocked out power in the ship while I was asleep in my berth and I got flung 40 feet into a dark, smoky hallway and wouldn't you know it I was able to find my DC station, guess Captain was right, thank god we had him."

Seriously, though, that poo poo was nuts and worth digging into if you find that stuff interesting.

I fully appreciate the details they added in the Crusader cockpit

Cyrano4747 posted:

Looking at my list I'd say the really useful ones are:

MechAttributeViewer
PilotOverhaul
TTRulez_AIMod (there are a few sub-mods for this, read the mod page)
BetterSpawns
YAML

required to make stuff above work:
Mod Options
MW 5 Compatibility Pack

Some nice QOL stuff:
BetterSalvageShares
PurchaseSalvage
ReputationLossCap
MechDelivery

Then on top of that I've got a ton of HD packs, shaders, improvements to the visuals and weather effects, etc. Just sort by most popular in Nexus and you'll find most of those.

VonBiomes is also really good for improving map diversity.

I installed YAML and now there are 500 more options for everything and for some reason my Hero Spider doesn't have an engine anymore?

Also a bunch of those mods showed compabitlity warnings, but it seems to be working okay for the time being.

I found an engine in a store so that works. How do I combine equipment to upgrade it? I don't see any menu options for that.

You remember the books? This is firmly in my dad's wheelhouse, and I'm kinda interested as well.

He had friends on the Samuel B, and I heard some amazing stories from that.

moroboshi posted:

Not sure what the question is, but you don't upgrade the engine directly. If you want to upgrade the engine in a mech you'd swap out whatever exists with a new one. For instance, swap an "Engine 200" for an "Engine 250" or something.

Ensign Expendable posted:

In the YAML settings it seems to suggest that you can combine multiple items of a lower tier to get one of a higher tier.

There's mods to change the number of parts required, but it's overall, not by weight/class. (Roger Tech runs from 3-8, which is probably "masochist" difficulty.)

Also RT, I need to get hold of a Salamander BA. If you lower the armor some a lot, you can stuff 3x BA Flamers in each suit. (Total 15.) Let Jamie pilot, for the additional 1 point of heat per shot, and apparently an additional flat 15% heat to the total inflicted, and someone is getting insta-shutdown, or at least "walk a little ways and do nothing".

Where the BA that swarmed them attacks again the next turn.

For Battletech is there a mod to change the number of salvage parts required by the mech's class? e.g. light mechs take 3 parts, heavies 5, etc...

I have found the standard IS BA drops work very well just because they jump on a mech, shoot it in the CT, then the mech basically powerbombs itself to get them off, then they jump back on it immediately on their next turn, so it spends the rest of the match repeatedly headbutting the floor trying to deal with the BA lmao.
