SA-2, S-75 Dvina antiaircraft missile propellant and total mass for each stage?
I want to calculate using "OpenRocket" the maximum altitude an SA-2 can reach in pure vertical flight. I am looking for an as detailed as possible presentation of this missile, especially for the parameters I listed below. If it happens you know a link to such a work please post it on this topic.
Searching on the internet I have found a single article that gives all the necessary data to calculate the flight path of an SA-2 as a function of time. Unfortunately having no other set of data to put the two side by side and make a comparison I can not know if I really have the genuine characteristics of an SA-2 (S-75) or some quite rough estimates.
SA-2 Stage 1
Propellant mass = 610 kg
Empty mass = 400 kg
Total mass = 1010 kg
Burn time = 3.1 seconds
Thrust = 350 kN
SA-2 Stage 2
Propellant mass = 715 kg
Empty mass + Payload = 200 kg + 475 kg
Total mass = 1390 kg
Burn time = 44.6 sec
Thrust = 35 kN
Total mass SA-2 = 2400 kg
