Good tutorial!  |
When you're on a perpendicular attack course, you have formed a right triangle (from you to the target, from you to the intercept point on the target track, and from the target to the intercept point). The distances the target and the torpedo travel to the intercept point (where your torpedo goes boom) is related to their speeds. The ratio of the two (target speed / torpedo speed) is equal to the tangent of the lead angle (the bearing to the target at the time you fire). It is not necessary to know the range to the target, except to make sure your torpedo can travel that far).
It's just trigonometry!
See the Angriffsscheibe Handbuch, example # 16 for a more detailed explanation with pictures.
