Shooting curveballs

[Xist]

First of all, I would like suggestions for a better title. I came to work today with every intention of, you know, working, but I had a Jalopnik article on my screen, and then descended into madness in the only site that I know with decent comments.

I had not realized any of these existed. Someone please explain why they had, you know, performance issues:

There is no point in curving the barrel except that it would allow someone to shoot from behind cover. You can't curve bullets.

I think most of the bent barrels came from WW1 trench warfare.

Disagree on not being about to shoot a curve bullet. Say instead of swinging a gun, lets just change it to shooting straight out the out the window of a car traveling 60 mph (88 ft/second). Say the bullet is going 1000 fps, In 1 second the bullet will travel 1000 ft(333.3 yards) away, and travel 88 ft in the direction the car is traveling so, you could shoot something obstructed by a building closer to you.

Krummlauf. Call it Krummlauf.

The bent barrel attachments had very short lifespans – approx. 300 rounds for the 30° version, and 160 rounds for the 45° variant–as the barrel and bullets fired were put under great stress.

It took me about three minutes to learn that. You're welcome. Steerable bullets is a different technology.

I read https://jalopnik.com/ten-obvious-eng...nto-1700377652, which contained:

“Porsche was so confident he would win the contract for the Tiger tank that he began producing chassis before the contract was awarded. When his design was judged inferior to the Henschel he convinced the military to let him build tank destroyers out of the chassis he had already began producing. So it began life as a loser.

Then they built it, but forgot to add opening for machine guns, or openings for vision to the side or the rear.

[...]

Not willing to call it a day and melt the things down as scrap the tanks were “retrofitted” by providing the crew with a machine gun with bent barrel so that they could fire at nearby troops through an open hatch. This of course meant they had to open the hatch in the middle of the battle, which kind of defeats the purpose of an enclosed armored vehicle.

That is not curving a bullet, as it still travels in a straight (diagonal) path from the point at which it leaves the barrel. Firing from a moving vehicle will not allow a bullet to curve around an obstruction.

Curved paths are an indication of continued acceleration by some force. A baseball curves towards the ground due to the continued acceleration of gravity towards the earth.

You would need to utilize the magnus effect, or other aerodynamic property to curve a projectile around an obstacle.

Just shoot it past something that warps gravity. Duh.
