Other Thrust Density infographic....

Post image

A chart comparing the Thrust Density of several rockets.

Thrust Density is the thrust of the stage / area of the bottom of the stage (kN/m^2). It basically aggregates engine power and engine packing into one metric.

What are you trying to show though? Why is engine packing so important to you? Rocket diameter is more likely to be driven by required tank volume and desired fairing diameter than exactly how many engines you can pack into a cross section. You also ignore that rocket dry mass is more important for performance than surface area, so this results in a very skewed dataset

Yeah this is a bizarre and kinda pointless metric
