Also if you need your arrows to land all at the same time so you can fool the enemy into thinking you are many archers fire like this.

bottom projectile traveling at mach 5

[–] Tja@programming.dev 11 points 3 days ago (2 children)

Bottom projectile is traveling at a normal speed, just fired last.

Then the distance must be almost zero, as it exhibits no drop over that range.

That might have something to do with this being a chart for powered missiles.

[–] FishFace@piefed.social 4 points 3 days ago (1 children)

The diagram is about normal unpowered shells. They use different amounts of propellant to achieve different projectile speeds

[–] Cawifre@lemmy.world 3 points 2 days ago (1 children)

Y'know, I think you're right. That gray bit looks like the tank barrel. I mistook that as part of the projectile path, and I misinterpreted the overall design as a missile battery.

If you want to know more, look up Multiple Round Simultaneous Impact

However, the comment was talking about arrows...

[–] HowAbt2day@futurology.today 17 points 3 days ago

I’m over here with some popcorn as nerds debate the project motion of a hypersonic missile named “arrow” and shit.

Go with a fantasy arrow made of light, for the last one.

Are we looking at the same image? DO I NEED TO GET A RULER?

[–] FishFace@piefed.social 1 points 3 days ago (1 children)

That is not how this concept, time on target, works

[–] Tja@programming.dev 1 points 2 days ago (1 children)

It works by firing at mach 5?

[–] FishFace@piefed.social 2 points 2 days ago

It's easier to just refer to "multiple round simultaneous impact" than to try to explain succinctly, especially since I already got the term kinda wrong (time on target is more of an umbrella category/earlier version)

I wanna see a reverse brachistochrone!
