The throbbing of the engines...or not!

Vacillator · 03-30-07, 03:15 AM

I searched for this and see that it's been asked before but couldn't find a defintive answer, so...

Running either electric or diesel I have no engine noise inside my Type VIIB, all the way up to ahead flank. Now I know I'm not stood next to Johann in the engine room but surely I should get something? Going external gives me some noise close to the camera.

Going external also showed me an odd thing. Was running diesels at ahead flank (and getting 18kts) to test noise. I saw that only one screw was turning, starboard was stationary! I thought 'that can't be right' so I went to 20m and then re-surfaced. This time on ahead flank I got both screws turning! Anyone know what gives? Surely one screw (ooh err missus) wouldn't give me 18kts?

Minor problems anyway but curious.

Oh I should say it's GWX 1.03 but I don't think I've ever heard engine noise in the boat.

I'm runnuing GWX1.03 and I do get engine noise, throbbing diesels on the surface and on diving a pause followed by the reasuuring whine of the electric engines.

Silly question but you have got fx turned up?

cardician · 03-30-07, 04:20 AM

The one screw turning could be because you were charging the battery. By default the helmsman charges the battery whenever you surface, hence only one screw turns. Sometimes its annoying when you want to surface and pursue a target and need both screws.

Vacillator · 03-30-07, 04:49 AM

Good points gents!

1. Silly question but you have got fx turned up?

Not a silly question at all. I haven't cranked them up all the way but I think all sounds are at the same level, will check tonight and adjust to check what I can get. Reckon you may have nailed that one so thanks for that.

2. The one screw turning could be because you were charging the battery.

Yes it could be, didn't think of that (so thanks again). However, I was still making 18kts which I would've thought unlikely with just 1 screw turning?

cardician · 03-30-07, 04:52 AM

That I wouldn't know. Other than the naval academy missions, I've only had the pleasure of manning a IIA so far. With both screws, surfaced, I'm lucky to get 11knots in good weather. I think even with the whole crew paddling we might get up to 12 :p

But yeah, if you've been submerged at all, unless you specifically tell the helsman to run standard or whatever, he'll just run one screw and use the other to charge the battery.

Hmmm, the plot thickens. I had ordered ahead flank, so should that over-ride charging the batteries? Either way I seemed to get flank speed with only one screw turning so perhaps I shouldn't complain

That makes sense, but no. I've found that you have to literally tell him by clicking on the appropriate icon to not charge the battery. There are two icons for how to run the engines. Sorry, all the proper terms are escaping me. The one on the right is to charge the battery while the other is to run with both engines and not charge the battery. By default he always puts it to charge the battery when you surface and I haven't anything that changes this other than physically telling him to run both engines. Hope that makes sense.

For an exact location, click on the helmsman, or whatever he is. The officer on the officer's bar that is all the way to the left. Then again on the bar that pops up, select the far left icon. There you'll see the two icons on the left. One is a battery and the other is a propellor. Those are the ones I mean.

Wow that was a piss poor explanation on my part. Sorry.

Au contraire! Very informative as it's something I've never done and I could understand perfectly what you meant! Thanks.

PS Hope I don't get keel-hauled for use of French.

The board of enquiry will commence at 9am tomorrow morning

Don't feed jimbuna trolling

No problem at all
but i use a mix with NYGM

Vacillator · 03-30-07, 10:47 AM

9am on a Saturday, that's severe! I must stop hanging around the docks with those nice French ladies.

EDIT: Oops sorry 1mPHUNit0.

1mPHUNit0 · 03-30-07, 10:50 AM

I's not a problem...i was joking

NipplesTheCat · 03-30-07, 10:50 AM

After surfacing the battery will be charged untill it reaches 100%. Otherwise you have to turn off the battery charge manually. Running on one screw I wouldnt expect you to hit 18knts though. Maybe 14 or 16,...but not 18.

The bit about turning off charging is something I've learned today, which is nice. The second bit I totally agree with.

I'm quite often hanging at 9am on a Saturday but that's a different form of punishment
