I'm trying to understand how much different parts of a rocket engine weigh. For example, according to Wikipedia, Merlin engine weighs 470 kg, of which 70 kg is the turbopump. How is the remaining 400 kg break out? I'm guessing the broad categories could be:
- Combustion chamber
- Thrust frame
- Swing assembly
Totally understand that this breakdown might vary greatly for different engines, but if someone knows directional numbers for different types of engines (turbopump vs. staged combustion vs. expander cycle, maybe on an example of real engines - e.g. Merlin, RL10 etc.), would appreciate the info!
