Firing Solution - Projectile Motion

Click For Summary
The discussion centers on calculating the lead angle for a turret in a sci-fi space battle scenario, where both the turret and target move in different directions without gravity or resistance. The user seeks a mathematical solution to determine where the turret should aim to successfully hit a moving target, factoring in the velocities of both the turret and the projectile. A basic understanding of trigonometry and geometry is mentioned, indicating a need for simplified explanations. The conversation emphasizes the importance of accurately predicting the target's future position based on its velocity. Visual aids, such as diagrams, are suggested to clarify the problem further.

This is problem that has been bugging me for the last few days and I fear I don't know the math to figure it out. (As is no education above geometry and a very basic introduction to trigonometry.)

I do 3D modeling and animation.

Assume this takes place in, say, a sci-fi space battle where there is no gravity or any resistance.

Within this scene are three things: a turret on a ship, a target, and a null (basically a single point that can be moved around and do other things).

The turret automatic points itself at the null.

I would like to apply an equation to this null that will move it to the point where it thinks the turret would need to fire in order to hit the target.

This would need to take into account the velocity of the target, the velocity the turret, and the speed at which the projectile travels.

Again, assume no competency in physics what so ever.

I think you are asking how to figure out how much the turret should lead the target, assuming they are traveling in different directions. Is that right?
 
Yes. Perhaps a picture might help.

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
