B Bullet lead with given parameters

Click For Summary
The discussion focuses on creating a bullet lead calculation system similar to the M1 Abrams tank's aiming mechanism. Participants are considering parameters such as wind velocity and specific projectile types, including .50 caliber and 20mm rounds, with ranges from 10 meters to 5 kilometers. The aim is to develop a model that accurately predicts lead for these historical aircraft weapons. The conversation emphasizes the importance of understanding both projectile velocity and target distance in the calculations. Overall, the goal is to refine the aiming system for effective targeting.

TL;DR
I am creating software that gets the following parameters ( bullet velocity, ballistic coefficient of a bullet, distance to the target, my velocity, enemies velocity) the program needs to calculate where to shoot to hit the enemy. I need an equation that calculates that After countless hours of wasted googling, I decided to ask you all, maybe some of you will be able to help.

Thank you for any help you give
:)

Welcome to PF. :smile:

Kind of like the M1 Abrams tank main gun aiming system?

Are you wanting to include wind velocity? What ranges and round velocities are you thinking about?
Yes kind of like abrams aiming system , no wind and WW2 Aircraft gun velocities (0.5cals, 20mm mg 151, 30mm mk 108/103, hispanos etc.) And ranges from 10m to 5km

Thread 'Why higher speeds need more power if backward force is the same?'

Thread 'Why higher speeds need more power if backward force is the same?'

Power = Force v Speed Power of my horse = 104kgx9.81m/s^2 x 0.732m/s = 1HP =746W Force/tension in rope stay the same if horse run at 0.73m/s or at 15m/s, so why then horse need to be more powerfull to pull at higher speed even if backward force at him(rope tension) stay the same? I understand that if I increase weight, it is hrader for horse to pull at higher speed because now is backward force increased, but don't understand why is harder to pull at higher speed if weight(backward force)...
