Eve equivalent to Earth for launching?

[kahlzun]

With it's ultra-thick and high atmosphere, and high gravity, Eve is the hardest planet to launch from.

What I am wondering is, how closely does it match launch requirements for a 'real' launch from Earth's surface?

I have heard that it takes about 8000ms to reach low orbit in both?

Thoughts?

12000 for Eve, the dV charts say.

Of course there's no real comparing as our universe has different energy density fuels and different scale engines to use that fuel as compared to the Kerbal universe.

In purely DV terms they are pretty similar, but due to the aerodynamics, the low TWR of Kerbal engines and the high empty mass of the tanks it takes a much more complicated rocket (more stages etc) to get of Eve.

From Earth's surface to LEO is about 9300-10000 m/s delta-v depending on the rocket.

If you want a better Earth analogue, try taking off from Jool at the 1 atmosphere level (around 27 km altitude). Jool is about the same size as Earth and has a similar orbital speed. Only difference is that Jool has a little less gravity at 0.8 g's, making it slightly easier to get into orbit.

Eve needs anywhere from 8000 to 12000 m/s delta-v depending on where you land, mostly because of its atmosphere being so thick. But Eve also requires much higher TWR since its gravity is a lot higher than Earth's.
