Die Panzerung hat mit dem Bounce nichts zu tun, sondern nur der Einschlagswinkel.
Ricochet Simplification The projectiles and the angles of impact are idealised, to make calculations less complex. Every angle of impact lower than 20 degrees counts as a ricochet! (10 degrees plus the 10 degree shell normalization). With one exception: If caliber of the projectile is three times greater than the armor and the angle is greater than 8 degrees, the shot will penetrate. All shells have a ricochet value and an idealization value. These are 20 and 8 degrees, for the most part, of the shells.
1. Check for ricochet.
If your attack angle is lower than 10 degrees (or, in other words, almost parallels the armor), your Shell will ricochet and you will not penetrate. If your Shell size (in mm) is at least three times the amount of armor (in mm) you are attacking, your Shell will not ricochet (unless angle is less than 8 degrees). If your Shell’s penetration (in mm) is at least two times the amount of armor (in mm) you are attacking, your Shell will not ricochet (unless angle is less than 8 degrees).
2. The Shell is normalized to the center line.
When a Shell first comes in contact with armor, it will screw itself somewhat into the armor. This action increases the angle of attack, as the Shell tends to „right“ itself towards a right angle (90 degrees) to the armor. Each Shell has a different value of normalization, but it normally increases the attack angle by 10 degrees.
3.Calculate thickness of armor.
The minimum armor thickness is the tank’s section of armor that you are hitting. If there is an attack angle to the shell, due to armor slope and/or angle from which you fired at the target, this increases the armor thickness that your Shell has to penetrate. For a more thorough explanation (and very helpful picture), see here.
The basic formula for LOS (line of sight) armor is: LOS armor = base thickness / cos(angle of incidence){ed note: this formula not reversed}.
Remember that for an attack angle shot (where 90 degrees is a straight side shot), the formula is effective armor = base thickness / sin (attack angle).
Also note that in Excel (which uses radians, not degrees), the formula would be effective armor = base thickness / sin(Radians(attack angle).
Armor with with a 30 degree slope would be effective armor = base thickness / cos(sloop angle) {Slope angles are typically not reversed. Thus, a 30 degree slope provides better protection than a 60 slope}
4. Calculate penetration value of the shell.
The base stat of your tank’s gun and Shell are used as the basis for this calculation. The distance between you and the target is also considered. At 100m, you will have 100% of your Shell penetration, but this decreases linearly down to 80% at 500m. Next, the penetration value is modified by Gaussian distribution with an upper limit of +25% and a lower limit of -25%. In other words, your Shell may have an actual penetration value of 75% – 125% of the displayed value (without range figured).
5. Compare the calculated penetration value to the calculated thickness of the armor.
If the penetration value is larger than the thickness value, you penetrate and deal damage.
