This is a recreation of the Atlas V launcher from ULA on it is the RD-180(1st stage) and two buffed RL-10A's
what do i mean by buffed? i mean instead of a thrust of 110kn its 330kn each. this is bc im a busy man and i am not waiting for 5 min for a burn. If you want to change this size down the engine and partscale up(the isp is unchanged. Another thing that i changed is that the rocket was alot heavier than its 330,000 Kg weight so i mass scaled the rocket to the weight.
so its not stock.
first stage: Thrust:3850 Kn Isp:320s
second stage: Thrust:660 Kn (combined) Isp:465s
- Total Delta V: 6.9km/s
- Total Thrust: 8.2MN
- Engines: 10
- Wet Mass: 640,923kg
