Delta V Cheat sheet.

[Kizami z3r0]

I was just wondering if there was a Cheat sheet to calulate Delta V to say make a round trip from kerbin to the mun on a orbit and then back again.

Nevermind i found one. http://wiki.kerbalspaceprogram.com/wiki/Cheat_Sheet#Thrust_to_Weight_Ratio_.28TWR.29 But could someone by any chance teach me how to read this?

What part of the map is unclear to you?

Reaching Mun:
4550dV to reach a stable orbit, 860 to intercept Mun, 210 to establish a stable orbit, 640 to land.

Returning from Mun:
640dV to lift off, 210 to make a nice orbit, 860 to intercept and then aerobrake.

Reaching the sun:
4550dV to reach a stable orbit, 950 to leave Kerbins SOI.

Rinse and repeat for other places.
Note: You can also use this map. http://www.skyrender.net/lp/ksp/system_map.png

So basicly I take all the delta v numbers and just add them up for a total estimation for a round trip?

Basically.

Another helpful tool for the calculation of dV is this one:
http://alexmoon.github.io/ksp/

It doesn´t include dV values to land or get into Orbit, but it is incredibly hepful in planning your start dates (and then point into the right direction (and attain the right speed) for your departure from KerbinI) so that you can choose an optimal launch window/approach with regards to minimum dV to be spent.
(and it also helps if you want to see the range between worst and best case for the different routes)

Cheat sheet? AKA vital info.

I use this map : http://i.imgur.com/UUU8yCk.png

Best all around i guess

[Maverick]

Just do what I do.

10) I build.
20) I fly.
30) If I get there I had enough dV. goto 50
40) If I did not get there, I did not have enough dV. goto 10
50) Go somewhere else.
55) If past 5.00pm, goto 56
56) Get beer
57) Drink beer
58) Check forums to see who I can annoy
59) Pretend I am involved in complicated space flight rather than talk to wife
60) If after 11pm, goto 64 else goto 55
64) If wife mad at me goto 70
65) Goto bed
66) End.
70) Sleep on couch
75) End.

Pretty "basic" really :)

PS: It's 2pm, why am I drunk?????

how do you know how much Dv you used then or have in your tanks? IF youre not using mechjeb? i dont have mechjeb so i just guess everything

[Kizami z3r0]

I make it a point to use the DeltaV on mech jeb. I have no intention of driveing my self insaine running out of fuel to get to my targets.

Either by using another mod like Egineer Redux mod or by calculating dV manually.

[IkkYuSoJuN]

thnx iv seen that helpsheet, i didnt understand the formulas, never was good at maths, so i should try mehcjeb just for dV

[Langkard]

Either Kerbal Engineer Redux or Mechjeb will work fine for calculating your delta-V.

The map gxs posted in his answer above is the easiest to use. The one posted by Zzabur is much more accurate and detailed, and thus better in some ways.

http://ksp.olex.biz/ does the same thing as the launch calculator posted by Proteus. It has a graphical representation of the relative angles of the origin and destination in their orbits around Kerbol and the point in a 100km parking orbit at which you want to begin your burn. I find it easier to use. I just accelerate time while my ship is on the launchpad until the orbits match the one given by the calculator. It's not as exact, but it helps train you to visualize the necessary orbital positions for a decent launch window.
