Hitech are M2 50cals on buffs better ?

[Samm]

From the tailgunner position on a b17 I can hit and shoot down planes that are 1500meters away, I have even hit them from 1.7.
I have never hit a plane farther away than 1100 with the 50cals on a fighter. Are the mg's on buffs modeled differently ? If so, why ?

[Samm]

Ok just did a test offline, 50cals on p38 will hit target up to 1300meters, they don't hit at 1400.

Front guns of b17 will hit target up to 1400 meters, they don't hit at 1500.

Tail guns of b17 hit target up to 1700 meters, they don't hit at 1800.

What's up with that ?

denial incoming!

[Samm]

The b17guns have greater range, so I presume the projectiles have greater velocity, and of course if they have greater velocity they will do more kinetic energy damage than the 50cals on fighters .

Please don't get angry, I'm not ragging on the game . I just want to understand this better .

Please no hijackers from Mandoland, I want this thread to be taken seriously .

Samm search for previous topics on this, the guns are 100% identical, but do to drag firing a gun backwards, the bullet will travel farther relative to your air plane.

[Samm]

Ok Hitech, thanks for replying. But what about the forward firing guns ?

[Samm]

Ok I did the test again, this time with both aircraft at 200mph, and guess what. The p38 guns had the same range as the forward firing guns of the b17(1400) . But once you go faster than about 250 in the p38 the range drops to 1300.  I have a better grasp of it now .

And do the guns firing backward get a lower velocity then the ones firing forward? For the guns firing forward it should be velocity + airplane speed while the ones firing backward should be velocity - airplane speed.

Is this modelled?

head on collision= bullets v + plane v (plane is flying into the bullets)
rear end is= bullet v - plane (plane is flying away from the bullets)


i think thats right, but i'm no phyics expert

[hitech]

It's V1 + V2 in all cases.

We are dealing with a 3d vel vector.  not speed.

And you can see that it is modeled by samm's test.

Btw even thow the bullet is travling less distance relaitve to the ground when shooting back, it's effective range relative to the plane is increased.

[Wilbus]

When the rear guns of the B17 shoot to the rear, their speed should be the velocity of the gun - (minus) the speed of which the plane is moving forward, wether the bullets hit harder because a plane behind is closing in fast is another thing, they should have less V then normal though.

[hitech]

Wilbus, you are mixing terms, speed and vel are not the same thing. Vel is speed and direction.

So if a plane is doing {0,100,0} and the bullet is launched {0,-10,0} they just get summed for all cases.

This may help .

[Wilbus]

But, let's say, without using any kind of real numbers, just make up some fantasy numbers.

A plane is moving with 300 feet per second in East bound direction. The rear gunner, fires a Bullet straight West (straight 6 oc) with 1000fps.

Shouldn't the bullet have a speed of 600 feet per second heading West?

[Samm]

In relation to the ground .
Not in relation to the gun that fired it, or the plane that is chasing the aft firing gun .
