Gyro Angle

cali03boss · 08-21-07, 04:25 PM

Maybe someone can help me....because I thought I was doing this all right but apparently not.

It is very rare that I ever use the gyro angle, and the rare times I do are usually when I'm faced with a convoy. I used to think that by setting the gyro angle 2-3 clicks over in the direction the convoy was traveling (relative to the bow)....you would be able to account for certain errors in targeting. It has worked so far. But recently I tried to do the same idea but at a single target, and at a closer distance. What ended up happening is the torpedo completely turned around on me and started going in the OPPOSITE direction.

My question is...how exactly do you use the gyro dial. When do you know to use it? And why is it not as simple as the Spread system used in Sh3?

you dont really "use" the gyro angle per-se. its mainly just an indication of how much the torpedo will turn.

the closer to 0 the gyro is when you fire.. the less the torpedo has to turn and the more accurate it will be.

but... you also want to keep an eye on impact angle. that is the pointer on the dial above that one. you want it to be close to 90 so the torpedo doesn't glance off the target.

it's a juggling act. waiting for the gyro to get to 0 might make your impact angle too great.

I was under the impression that the gyro angle does not change unless you set it to change.

The TDC automatically sets the gyro angle. That is any solution that has the fish on a heading other than the sub's heading.

Do you mean the spread angle on the torpedo setting control.

The spread angle is a relative angle off the TDC computed gyro angle.

Maybe I mean the spread angle...but the dial for it says Gyro.

If i'm wrong...how do I set the spread angle?

I've been spreading my shots by redoing range and bearing estimates.

if you use the PK, every torpedo fired will be aimed at the center mass of the ship (or whichever part you were aiming at when sending the bearing data).

to hit other parts of the ship with successive torpedos, you adjust that dial to gyro the torpedo more or less.

so basically. fire 1 torpedo, then set the dial left alittle.. fire a torpedo.. then set the dial right alittle and fire another one.

The spread angle is degrees off the current solution, left and right. It is GLOBAL, so if you are ready to shoot, and move to tube 2, set a 1 degree right, then to tube 3 and set 1 degree left, then open tube 1 and shoot, it will be 1 degree left. *(that make sense?).

So to fire a spread, shoot a tube at 0, then move to another tube, set the offset angle and shoot, then another tube, and whatever spread angle and shoot. I always try to set it back to zero when I'm done or I will certainly screw up the next shot, lol.

This is one of those cases where "full manual" shooting in unrealistic. The skipper would have a crew, and he could very well order a spread---the TDC wouldn't do it automatically, but his crew would (meaning to the skipper it doesn't matter if it's a black box, or a guy with a screwdriver, he says so, and it gets done).
