Eve Manned Mission- devolpment phase, RnD question

[xcorps]

How can I go about getting a rough feel for how a design will work on Eve?

I'm thinking I can use the test part from NRAP mod to simulate gravity by adding weight to the lander for the lift off portion of the mission. How can I figure out how much weight to add?

I hyperedit Kerbin to have Eve's atmosphere. Always do this in a save game other than your main one though.

Hyperedit is a mod?

Thanks, I'll give that a shot!

Alternatively, you can use Kerbal Engineer or MechJeb, which can report your TWR on Eve while constructing in the VAB. As long as your stages have a TWR high enough (1.5 is a good minimum) and around 12,000 m/s of total delta-V, you can get off of Eve. That way you can tell if the vehicle has the ability to leave Eve from the surface, just from math. The rest is up to you.

Besides taking into account the TWR which I also advice to check with mechjeb in the vab. I also recommend practicing in eves atmosphere with hyperedit as mentioned.

Even if you have enough delta V and TWR to get into orbit theoretically. You have very severe restrictions to terminal velocity on eve. That means you can very easily waste alot of Delta V by ascending to fast which then costs enormous amounts of delta V. So I would suggest practicing terminal velocities on ascend a couple of times so you know what ascend speed to maintain during different layers of eves atmosphere.

There is a table of recommended terminal velocities on this page. http://wiki.kerbalspaceprogram.com/wiki/Eve

And I recommend practice on the basis of those values.

Also don't forget that all your stages need to have a TWR sufficient enough. And usually you need multiple stages to ascend on eve. So besides carying alot of fuel you need a sufficient strategy of high energy engines on basically all but the last orbit insertion stage.
