Question on game physics: BULLET SPEED ( simulator )
 

Hello boppers!

I would like to ask a question to you, about bullet speed in this game:

Do you think that phisical game engine make the bullet speed affected by the plane speed as well?

( Example: Lets say my machine gun bullet speed is X. I dive, flying at 600 km/h and i shoot. Will my bullet speed be X + 600? Or, i climb at 90° angle, shooting almost at 80 km/h. Will my bullet speed will be X + 80? )

I am not a good "boom and zoomer" so i am not sure how to lead a target from far away,
I am not sure about it, what do you think?

thanks for reading!

What happens is the bullets very quickly slow down due to the airflow. There were some cases in WW2 where aircaft shot themselves
down when firing at a target and diving into thier own rounds.

It also happened to a Grumman F-11F Tiger. 11 seconds after it fired a burst the flightpaths met and down it went.

That's very interesting Winny, I didn't know that had occurred. I wonder if it was tracers that caused that as I presume they travel slower

the randomness of war,i see a tv show about ww1,there were allied bodys found around the edge of an allied fired shell crater in enemy territory,they had blown the whistle after the barrage stopped but 30 seconds later(could be longer)all the mud and crap came down

Good question vdomini... I think it must be a question about output speed. The moment the projectile has left the barrel, it is 'out there on it's own' dealing with gravity and friction - and the plane, if fast enough, is capable of catching up with it's own projectile. The analogi is ex. firing from a car or a train. The projectile does not carry with it the speed of the vehicle. I think... But to be honest, it's a while ago since I f*#d up my exams in physics...
Do anyone know what the output speed was for ex. a 20 mm?

Here's a link to the F11 shooting itself down.

Muzzle Velocity for a 20mm is between 500 and 800 m/sec for guns of that era. Hispano is about 750 m/sec. 400mph is 179 m/sec.

Thanks winny. Take it that it would be a hell of a dive for a Spit to catch up...

I'm guessing that the drop off in speed of the rounds must happen quickly, balistics give me a headache.

A Spitfire broke the sound barrier in a dive once.. I think it also fell apart.

Thank you for all your kind answering, my question was concerned more about the game physics than real. Still wondering if initial shooting speed is involved :cool: ( In real bullets travel very fast, it's impossible for a ww2 propelled plane to catch their own bullets, even during dives i think )
