[0.17 .cfg edits] Eve-Sim 'Stock' Parts

Eve Simulation Stock Parts

Don't like wasting time? Instead of flying all the way to Eve to test out your Eve lander designs use the Eve-Sim^TM parts!

The pack consists of the .cfg files for all of the standard parts available in 0.17 with a crucial difference; for each and every part mass values have been increased 1.7 times so as to accurately simulate Eve's gravity on Kerbin.

Not only that, but each and every parts' drag values have been increased by 5 times to simulate the density of Eve's atmosphere on Kerbin.

No more wasting time flying to Eve to find out that your lander design ain't worth a d**n, simply use the Eve-Sim^TM parts pack and do your testing from the comfort of the KSC!

One word of warning, this pack is still only allows for pseudo-realistic testing as Kerbin's atmosphere is only 70% of the thickness of Eve's. Still, should give you a good idea on what works and what doesn't!

Below is a comparison of launch vehicles; One using standard parts, the other using Eve-Sim^TM parts.

As you can see, with the Eve-Sim^TM parts the vehicle reaches about ¹/5th of the stock vehicle's altitude.

Good luck with your testing!

DISCLAIMER: I in no way claim the parts in the pack as my own, they are SQUAD's work. I simply edited the .cfg files so that you didn't have to!

EDIT: I quickly realised I'd uploaded the wrong zip, with all the models etc. Now you can simply download the .cfg files. If you decide to use these edited files do not forget to back up your originals, as changing them back manually is time consuming!

This is a fantastic idea! Now i can stop designing catastophic failures!

Could you do some simulated lift parts please?

[Excalibur]

I got rather fed up with the catastrophic failures too - hence why I spent an inordinate amount of time changing numbers around.

Regarding the lift parts (wings, winglets and control surfaces); I only changed the drag values, but kept the lift coefficients the same. At the time I thought that would simulate Eve the most accurately but now I'm a bit unsure since you bring it up. Should I leave them as they are or multiply them by a factor of 5 as well?

An issue with the mass edits (the edited drag is fine).

A similar idea was attempted when the Mun was released, after discussion it was concluded that physics doesn't work that way.

Using these parts you will find two things to be true:

First, that the response to lateral and angular RCS input is slugish. If you do build a lander with a quick response time you will have an overpowered RCS setup when you get to Eve and you'll be hauling too much RCS fuel to compensate.

Second, this is only accurate if your net force is 0. Your engines will not provide a representative amount of Delta V, successfully landing a modified lander from kerbin orbit, means that it is drastically over powered, and usually means you're carrying more fuel than you should be.

If you like, or think I'm wrong, I'd be more than happy to walk you through the physics involved. If you get a working test lander with these parts, the stock version should still work on Eve, but you'll notice your RCS and fuel tanks are quite a bit fuller.

-Happy flying!

I'm guessing this is due to increased inertia since on the real Eve only 'weight' has increased, and not mass? I should really think things through before going ahead with them!
