Th3F3aR

Well my week-ends drift away, this weekend i might have time on saturday, anyone of you guys up?

I know This is to estimate the dV output of the rocket

I'd suggest mounting it upside down

You just need to use the rocket equation Normally you calculate with: Ve * LN(Mfull/Mdry) -> To calculate payload just add it to Mfull and Mdry => Ve * LN(Mfull+P/Mdry+P) = dV There you go

You are right in terms of the first stage capi3101, but what is with stage 2 if there is one? I doubt that he created a one staged lifter with 5000+ dv? It's possible yeah, but i doubt that. If you assume that stage 2 has 150t less (with a basic TWR of 1,6) of the mass left and therefore approximately a thrust of ~3200kN. Then it might be different with the TWR, that results in approximately 1,03 which is quite low. So i won't say TWR is no limitation for that lifter Edit: My 50T lifter (well it might not be the best configuration) Mfull : 430250Kg dV: 5200m/s (with Payload set to 50Tonnes) s1 : 430t/302t | 8000kN | 1,9 TWR -> with payload 1,7 s2 : 262t/118t | 3200kN | 1,24 TWR -> with payload !1,04! s3 : 88,5t/16,5t | 2500kN | 2,88 TWR -> with payload 1,84 My limiting factor is stage 2, that definately needs a rework on thrust. But the 5200m/s are okay, and i can squeze out bit more by reducing thrust while in stage 1 and 3 Edit 2: okay Grotoiler, Isp is given in seconds just like on the ksp wiki parts page, i use the Ve with is given in m/s (Isp is Ve basically but not in terms of units ), you can read that by hovering over the isp values on the wiki Yes g0 is the gravity of the body you are taking off from Edit 3: If i didn't mess up and you use a 112,4t Payload you'll get a total dv of lousy 2493,8m/s So yeah TWR is not limiting in this case but you just don#t have enough fuel Equation parameters Ve : 3142m/s | Mfull : 460t | Mdry : 208t (fuel used 252t) With a payload of 50t you'll get at least 3123,9 m/s dV With a payload of 25t you'll get 3659m/s dV You see, without staging you lose way too much dV cause you transport a some 100t of b**** with you all the way up

You could do this with the following equation (?Rocket equation?) : dV = Ve * LN((Mf+P)/(Md+P)) dV = you know that already Ve = basically Isp but with the g0 in it (Isp*g0) LN = Logarithm n Mf = Mass full (without payload) Md = Mass dry (without payload) P = Payload There you go, do this equation for every stage and sum it up to get your output dv and you see if you got enough power to lift it up EDIT: Important, also watch your TWR on adding a payload, it could happen you get a good dv and a TWR less than 1, so check that always

Well i can only assume, but maybe you find those saves somewhere deep in your user directory. Roaming or Temp, but i can just assume. Never had that problem as i run it with admin permissions :/

My 50 cents on that, it'll be like dwarf fortress, it'll be hard, it'll be just another way you need to think. And after all, Kerbals without Lifesystems will disappear. I took that step and was absoloutly frightened, but i did it and it was awesome, more funny and more intense BTW: Nice report, well done on that training flight

Aye, I'll send you a message if i need it up. Will do the crafts in a local save and then copy them to the server

I didn't manage to the stuff properly, thats why i have nothing sent to orbit on the server, the stuff i had to do this weekend took way more time than i expected :/

Basically, i'd say, forgett it. I tried it myself and you just can't get the airresistance equation get to work without a knot in your head. That's why even in real world such things are estimated and from time to time acknowledged by tests. To get it "right" you should be physicist (does one write that like that XD?) or something like that to just understand whats going on! If you still wanna give it try (although it seems totally unnessesary for KSP) check out this linky -> http://exploration.grc.nasa.gov/education/rocket/dragco.html Nasa got all the things you need, described step by step. Maybe you get it done, i was to lazy to get all of it in my head

Yes, i do know If that's all so "easy" the fleet could be up on saturday night, got quite a lot to do on saturday but well it would be your afternoon then XD

Nice work on that beast Looks promising to lift some tonnes of payload to the most destinations !

Wow That is the amount of fuel/power you have to change your velocity (Basically) For a moar detailed insight -> http://en.wikipedia.org/wiki/Delta-v

This story really made my day Reading it on one side and meanwhile watching the todays spacewalk, great combination! Keep up your good work, although it's "newbie", it's interesting, and you did one of the best things with it, to share it while you are progressing BTW: Hope that mun mess cleans up soon
