First time I've seen this in a sim (haven't played Janes mind you) - usually you get that annoying representation of your fire whereby every round expended seems to be a tracer.

yeah I have seen they tracer rounds and they are cool though I think the ones in b17 are better. You are right about the ones hitting the plane. I did not see them do so, so I thought oh well I missed how could I miss from that distant, then I got to my log book and to my suprise I have claimed 16 kills. SSH woooow

Interestingly, I heard from someone that the "wiggle" effect is due to the camera in the aircraft shaking. In real life, there is no "wiggle." It makes perfect sense.

I think thats the way Wayward, the makers of B-17, explained it on there homepage.

Hence the reason that rounds fired have a "mean point of impact" they will *never* hit the same spot on a target on a set range on a bench-test indoors in a climate controled atmosphere.Rather measured from extreme to the centre of the target ie 5 rounds grouped within a 3" circle gives it's "Mean point of impact"

No two rounds are truly the same

...which is bolted to the fuselage. The camera wiggle is the fuselage wiggle - porpoising. You can see the 109's doing this when pulling up hard.

You're right Gambit - once the rounds leave the barrel it's straight line Newtonian stuff. The wiggle is in the eye of the observer.

Vibration from the guns wouldn't cause the tracers to have a sine-wave component (sorry, not meaning to sound like a smartass <g> ) This is a standard component of a resonance in the airframe - sine-waves somewhere are easily identified as resonances.

>Even the smallest movement of your normal camera at a slowish shutter speed (say 125th/sec) will result in a blur.<

Yep - blur being the word. The sine-wave is the giveaway.

>The vibration of four-eight MGs firing that are strapped to the aircraft would have been more than enough to cause the film plane to move ever so slightly giving the squiggly effect.

Yep - and this is added to the vector and sine-wave component. The sine-wave is a dead giveaway that something is undergoing a simple harmonic oscillation, a flutter in the airframe.

>All projectiles follow a trajectory once they leave the barrel until they strike an object<

Hopefully yep

>Aircraft porpoising while firing will only increase the size of a beaten zone in the same way that kicking the rudder will allow you to increase your spread across a target<

You've hit the nail on the head. The rounds are spread because the plane spreads them as it revolves/oscillates *around* a forward vector while the rounds are leaving the barrel(s)

Kicking the rudder is a slow process - 0.5Hz to 2Hz.

Harmonic oscillation of an airframe is a very fast process at 200kts - almost any vibration mode is possible and certainly 5Hz - 100Hz.

Cool discussion this
