Question on game physics: BULLET SPEED ( simulator )

[McQ59]

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?

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 ( In real bullets travel very fast, it's impossible for a ww2 propelled plane to catch their own bullets, even during dives i think )

[SEE]

Fire a high velocity bullet horizontal to the ground and drop one at the same time from the same height - both will hit the ground at exactly the same time. The force of gravity acts equally on both irrespective of the horzontal force use to fire the high velocity round.

Its all meaningless in BoP anyway because the bullets really arn't affected by gravity or drag at all. They just fly off at muzzle velocity and into infinity if they don't hit anything. Thats one reason why in BoP its so easy to shoot down someone who is in a climb. And why with unlimited ammo you can shoot down planes with the G-6 nose cannon from outside the range of a modern short range IR missile.

dude i will have you answer your own Q. ok ok ok land ok ok ok stop ok ok ok shoot! do yo move when shooting? well shit there you go!

LOL

i did what you said and.. the plane was going backward due recoil!
But, what does it mean? initial speed is taken in count or plane speed just reduced a little while shooting?
