manual solutions and math

CptSimFreak · 01-21-2007, 09:21 PM

I need small assistance with manual solutions and math behind it. I’m playing torpedo training mission and practicing on C2. For some reason all of my fishes land way ahead of target. What am I doing wrong? It seems that actual speed of ship is much slower than my calculations.... can anyone find my mistake.

I think if you take the .368 multiply by 10 you will get knots which
is what you want. Not Kph.

CptSimFreak · 01-21-2007, 10:00 PM

386 meters to nmiles = .2084 . That makes speed of C2 to 4.16. That makes more sense. Thanks.

Why would metric system use imperial units......bah.

Too many numbers makes mookie a sad little Kaleun :rotfl:

All the math made my head spin too!

I just read the thread on kilometers verses Nautical miles
a bit ago and made sense to me.
:rotfl:
Even if I wasn't right, I'm glad if it helped!

I get 3.98350559 knots, which is the same as your answer.

I like your sig

hehehe

so, now we have speed. Lets get AOB.

Oww! My head hurts now!!

I'm going back to the mod work Gents!

Easier on me old head!

So finally lets get distance. (and now, I need to figure out calculations from a moving vessel)

Gezoes · 01-22-2007, 02:23 AM

Now this is plain scary.

Math... brrrrrrrrr! :rotfl:

melnibonian · 01-22-2007, 02:27 AM

Seems perfectly straight forward to me actually

But on the other hand I make my living from maths so I cannot really say anything more

Maths though are fun:p

I'm ready to watch you tackle firing the deck gun on a windy day... Near a gravity well... On the surface of a 9-dimensional sphere... With man-eating dolphins chasing you...

Sorry, it's late and I majored in math.

I could do that only if the space we're in has Hilbert properties and the deck gun ammo is Hermitian. If and only if those conditions apply then we can use Feynman's path integrals to calculate the best way to avoid the man-eating dolphins around the gravitational well. The 9-d sphere will cause some trouble but based on the boundary conditions we might avoid losing a limb to the carnivorous sea mamals

:p

Well, I am damn lucky to have a WO who calclated this for me. I as Kaleun of the ship just makes the decisions, they do their job.

I would let my self the luxury of being sneaky...

Let the time from 1st Reading to 2nd Reading be 3 minuttes and 15 seconds......

You will be able to cross check speed on the plot and the final computation

SqRot 136067 = 368 meters per 3 min 15 sec would equal 3,6 knots (knowing that that does not represent the ACTUAL correct number in this example as angle 2nd Reading would have been about 360 or more for the extra 15 seconds.

You could then quickly plot it on the map and check to see if your final speed and Range calculations look good.

But a very cool and thorough sheet you made there....I should make them draggable in the Attack Peri view..

The only thing you did wrong was to time the readings at 3 min's - Instead time them at 3 min 15 sec. and you will have straight Knot calculation in the end.
