UB-40 Stock submarine

Recommended Posts

Something that may be of use to any budding marine biologists out there.

[B][U]Operation Manual[/U][/B]

Hyperedit may be the best way to get UB-40 into the water, but if you don't use hyperedit, just stage the engines and drive it off the end of the runway.

Once in the water, stage to jettison the land wheels

Throttle up to start moving. Once underway, press action group keys 1, 2 and 3 simultaneously to drop below the surface.

Once comfortably under the surface, press action group key 2 to reduce the amount of negative buoyancy. If you want to sink faster, omit this stage, but be aware that your rate of sink may be difficult to counter if the bottom suddenly looms large beneath you. Reducing the amount of negative buoyancy makes the craft easier to manoeuvre in the vertical plane just using the normal flight controls

Switching the external lights on will help you to determine when you are getting close to the bottom.

[B]Additional notes[/B]

Returning to the surface is best done in a controlled manner, just by 'flying' up. In emergencies, press action group keys 1 and 3 to introduce positive buoyancy in the fore and aft ballast tanks, but be aware that UB-40 in this configuration is likely to breach the surface at excessive speed, briefly becoming airborne and possibly resulting in damage as it smacks back down in to the water.

Once back on the surface, use action group keys 1 and 3 to maintain positive buoyancy.

Attitude trim whilst underwater can be done by transferring ore between the fore and aft ore tanks. More delicate changes can be made by making the transfers between the tanks closer to the middle of the boat.

Action group key 5 toggles the periscope.

Engines at 2/3 ahead give the best compromise for speed and distance, only losing a couple of m/s compared to full ahead.

The 'brake' action group key can be used to put the engines in reverse thrust if you need to slow down quickly.

She looks great in the water! I almost didn't click due to that most horrid collection of letters.. UB-40.. shudder.

Anywhoo, awful, awful music aside she really is a lovely looking vessel. Good job man.

The name was off-putting... But I love that ballast solution. How did you figure that out? I just [s]tried ripping it off[/s] learning from yours. Does it work with the bigger mark three cargo bays? So simple! Just open the doors and it sinks... Close them and it surfaces. +rep

[quote name='More Boosters']Ore tanks, dump ore and you gain buoyancy.[/QUOTE]

Not correct. Actually, that is true, but it's not how this boat works. If you dump ore you come back to the surface but are then unable to submerge again. The action group keys for diving are linked to the cargo bays, which become negatively buoyant when closed. No idea why. I did try using a greater number of the smaller cargo bays to give a more delicate control of the dive/surface process, but they don't seem to work.

I was wondering if the crew frequently enjoyed wine. Red, red wine.

You must use [U]separated[/U] cargo bays. Like fueltank-cargobay-fueltank-cargobay-fueltank, not fuel-cargo-cargo-fuel. Linked small bays count as one large in this case.

I'll have a look at it as I put it up using my mobile phone after having problems with Dropbox yesterday.

ETA: Original post updated. Should work now. Edited by Scarecrow88

Would you say it goes to their heads?

Neat little craft. When I finally get around to upd8ing to 1.0.5 I'll get her a whirl. Never could design boats, myself.

After a few glasses, Bob is thinking "Where did i go wrong" while Jeb and Bill are singing something about a Tyler Kerbin guy... :P
