Looking for factual data on fireworks physics.

Okay i'm interested in learning more about fireworks for a game project of mine, but it seems that either nobody took actual measurements, or it's a trade secret. WHat's i am looking for is basically technical informations about firework pieces, like the different size, their maximum velocity, how high they go, how big is the explosion supposed to be, etc etc...

I know that all fireworks are different, but they probably all obey to the same principles and stick to certain regulations.

I' starting to think that most of the hard data is kept solely in the pyrotechnician communities and only shared with those who are certified pyrotechnicians (which i can somewhat understand, it's dangerous after all.)

Does any of you is, or know a certified pyrotechnician than would be willing to enlight me on the specificities of the pyrotechnic supplies available out there (both consumer and display grade), so i can produce a model that is as accurate as possible?
