How do I turn off the torpedo computer?

[ttraveler]

Id like to make some dead reckoning torpedo shots using only the heading of my uboat to make a straight forward shot straight out on that heading.

But if I'm tracking a ship in the view finder of the periscope, don't the figures showing automatically go into the settings on the shot? How do I turn off these setting from going into the shot calculation and track the whereabouts of my target at the same time? I know the course heading of my uboat and I just want to track him to a certain bearing and range before pushing the button and launching my dead reckoning shot. How do I do this?

If I understand you correctly, this is easier than you think - just switch your TDC to manual, set your periscope to '0' and hit fire when you are aligned with the target.

Of course, you might want to make some adjustment to the range but your AOB would be still be '0' and any maneuvering would then be done with your rudder while watching the target thru your periscope!

If your target is moving - and most ships do! then you will have to determine at what point you fire your torp, the nearer you are to the target - in these circumstances the better, as it will quickly cross thru your periscope view...

Firing your torp 10 degrees before the bow of the ship reaches '0' may give you a hit - again if you are close and your target is moving (slowly) you will have good results!

Hope this makes sense and I (from your post) assume you are just wanting to 'AIM' instead of making regular manual TDC adjustments!

Geez bud going back to WWI? The uboot did use their TDCs, mind you sounds like an interesting way to aim.

[ttraveler]

Aim. Great choice of words! I like that description. That's what I want to do. Aim at a spot on the ocean. Not at a ship.

Here's an example of only one of the things that I want to do.

I want to do a bow shot on a pesky destroyer. I have no time for settings anywhere. He's coming straight at me. I'm going straight at him. I launch my dead on bow shot. Next I want to make two more quick torpedo shots. One by turning my sub to port and launching the second quick torpedo at whatever bearing my gut tells me at that moment to port, and the third torpedo shot by turning my sub quickly to starboard and launching that third quick torpedo at whatever bearing my gut tells me to at that moment in that direction. I just boxed him in.

I need to have that target locked in my periscope view so I can see the bearing and range on him at all times in my periscope for him. So at, for example, if he is bearing eight degrees off my sub's compass course at such and such a range showing and I have determined I want to shoot at that bearing and at that range based on his actions that I see in the scope then I need to make that instantaneous decision to launch that torpedo straight on that compass heading at that imaginary location that I think he will be at to port IF he goes to port. And then the same mental calculation to starboard IF he goes to statboard. After my third fish goes, then I stay on starboard (or port) to dive out of the way.

I am moving. This is at close range. I don't have time for torpedo data computer settings.

I need the TDC dead turned off so it effects my aiming my torpedoes in no way. I need to shoot my fish only at my sub's heading in the compass direction of my course and I need that shot launched fast because of the close range tactics. And I need to continuously see the range and bearing.

So I need to figure out how to set my torpedo launches at dead center forward on the compass heading of my sub while being able to view the quickly changing range and bearing data while viewing my target continuously in my periscope.

Is there a tutorial somewhere about How To Set The Torpedo Data Computer for SH3 that will explain using it to me so I can learn how to do this?

Aiming and 'shooting from the hip' can be accomplished two ways -

1. just go to TDC, set manual and observe your target on the TDC screen!

2. As I already suggested - set your TDC to 'manual' and turn your boat to aim and just hit fire (enter) when you are ready

Of course you can do these things in camera mode (F12) and use the little'orange' marker as your sighting tool!

Anyway this link will probably set you right:

Thanks for the link. I'll check it out.

TTraveler, I understand what you are saying completely.

When we're 'dogfighting' with a destroyer, we don't have time to take measurements, especially the targets-speed. By the time that measurement is taken, its too late to take the shot.

BTW, I play with as much realism as possible. I don't use the 'satalite overhead imaging system' / 'birds eye view.'

I too will look at that site.

Thanks.

After checking into things further, I'm on the way to doing what I need except for one thing.

After using the TDC for previous torpedo shots, how do I reset all settings to zero quickly after clicking on the Manual Button and seeing it turn green? Is there a reset to zero hotkey or mouse click?

Exactly! Good to see another dogfighter posting. :up:

Also, depending on the circumstances, reloading for another shot may not be possible.

Turning the TDC off would also help from when struggling to get a good angle on those squirely merchant ships when at close range.

I'm new too, and little time to play, but I'll post here when I find out.

Yep!

That's one of the other dead reckoning shots that require the bloody thing to be off and set to all zeros.

So how do we get it reset on exactly all zeros? When leaving base it is set on all zeros. But trying to reset it after an auto reading while on a mission seems impossible. I can get it down to about a half degree but it needs to be reset to all zeros!

You don't need all the inputs set back to zero, just the speed. With a speed of zero, none of the other calculations make a damn bit of difference.

That's interesting. I'll give that a try.

I do like to set the range. That way you get a time to impact reading.

I just tried it. That is ABSOLUTELY NOT CORRECT.

It's the bearing that must be set to zero. Range, angle on bow, and speed do not matter. However, and I repeat however, the angle on bow setting CAN be used for fine tuning to get that important Gyroangle back to perfect zero. It's the Gyroangle that must be at perfect zero to get that straight ahead torpedo shot.


A successful discussion in this thread. Thank you mates.


:cool:

[Knotical]

Actually Trav_R is correct, if you set the TDC target speed to zero, the torpedo will fire directly down the bearing the periscope or UZO is pointing, making it into a point and shoot system. Therefore point your sight to 0 degrees bearing and it will fire straight down the bow.

[Marhkimov]

Actaully, I think this is what ttraveler wants:

He wants to shoot a torpedo directly ahead (0 degree gyroangle) and still be able to turn the periscope without it directly affecting his gyroangle.

Is that a correct assessment of your request?

If this is the case, then the solution is simple. Set your bearing to zero. Don't worry about setting speed, range, or AOB; I don't think it matters. The important thing is to leave your TDC button on green (as opposed to red). A green button will give you exactly what you want: a manual torpedo shot.

With this setting, you should be able to move the periscope around without it affecting the direction of the the torpedo shot.

At least that's what I think... I haven't tried it yet...

[Marhkimov]

But it IS more useful to set your target speed to zero knots and use your periscope as an aiming device. "Firing from the hip" as it's called...

It's just IMHO, but firing "straight and center" is useless.

[Trav_R]

Markhimov: You're right except for the speed, you still need the speed at zero. Bearing 0, Speed zero, leave it in manual (green light) and there you have it. If the speed is nonzero (target is moving), the TDC will calculate the lead for it and the angle will not be straight ahead anymore. Therefore, speed is the #1 most important input for affecting gyroangle. With no speed, there's no need to lead the target.

[Marhkimov]

Oh, you're right. :up:
