    ... Transfer to a Polar Orbit.

    in KSP1 Gameplay Questions and Tutorials

    Posted · Edited by Atimed

    -If you want to go from a equatorial orbit on Kerbin directly to Muns Polar orbit, you need to incline your Kerbinns orbit by a few degrees (3-5°) relative to the Mun..

    -Its allays 90° before your Munar Injection Point.. Then you just do a Munar Insertion.. after that when you get into Muns SOI burn until the orbital path is alighned vertically.. (passing over the poles) After that is just a fact to do a circularization and viola.. Just deploy your mapper and you're good to go..

    Am I the only person?

    -I have reached all the planets, but landed just on Duna...

    -However i have ISA Mapping satellites in polar orbits around all planets and moons.. Gilly is giving me problems..

    -I like having height maps 1st.. Before i go to the surface..

    I have a somewhat difficult time believing that electrical power-generating solar panels would actually be viable options for Kerbals.

    -The guys will sure find a way to make it happen, if panels are to safe, use nuclear generators, or thermo nuclear...

    -Since they already got the tech ..

    -But id like to see something like ..

    -Its not like they do anything, besides smile and scream...

    -Make a part that has got 3 bicycles hooked to the ship battery, and Viola free energy..And it will keep them fit.. :P

    I like the Idea of the NERVA.

    So much energy we can bring up in orbit now.

    (Energy = Total Movement Change / Fuel) (ms^2/kg)

    So ISP 800 m/s means 800 Ns/kg or 800 Newtonseconds per kg fuel)

    A Newtonsecond is about 1 meter and 1 kg per second movement.

    If we apply that to TMC (weigth assumed= 1kg) we get 800 meters per second

    So the small tanks have about 300 units of fuel (300 kg assumed)

    Applied to Fuel and Calced: 8/3 ms^2/kg ~ 3 ms^2/kg

    Means this engine would move 1kg (hope its right) at a velocity of 3 m/s² per kg fuel.

    I think that is good.

    Your formulas are correct,but remember that 1t = 200l of fuel

    So so 1l = 0,005t = 5kg

    Getting back to NERVA engines and thrust to weight ratio: its not true that NTR (NuclearThermalRocket) engines had TWR less than 1 or they had really low thrust - NTR had TWR of ~4-6, this mean that this engine could lift (but go very slow or none, so for serious acceleration payload should be lighter) 4-6 times more payload than engine weight... it seems not bad (stock engines aren't pretty better), but chemical rocket engines had average TWR between 60-80 to 1, for example Saturn V F-1 engine had TWR of 91 and new SpaceX merlin 1D engine had TWR of 160 to 1 (this mean that falcon 9 rocket engine can held 160 times heavier payload than it's own mass !!!), so NTR engines aren't very weak (little worse TWR than Concorde aircraft engines) but they can't compete with chemical rocket engines in this field (thrust).

    Btw, stock engines in KSP aren't had good Trust to weight ratio either, so difference between them could be smaller :P.

    True we should compete to realistic engines and crafts, even if little green jelly Kerbals are flying on ICBMS..

    But things should be fun, and be changing.. If you ask me Hard as hell...

    One thing I hope that they make NERVA engines, Heavy, Prone Overheating and Powerful..

    Compared to LV-Ts.. 50%-80% more Thrust..

    I'v tried to emulate them by some basic .cfg edits.. and if u use the 800 IPS you can do wonders with just one tank..

    A 1m engine around 6t, thrust 300 and ISP~600 would be perfect for my rocket(s).. :P

    They are in fact the same/more less.. I use relative distances for my insertion calculations because i need jut the angle...

    While you use the whole equation with 2Pi and the Gravitational Constants of the orbiting body..

    I just noticed how i could approximate gravity of the target body, without consulting the wiki..

    Time to test it on Kerbal.. :D

    Thx for sharing and Keep up the good work..

    I have the equations for interplanetary transfer angles prepared and ready to go for official distance data; when that data's available, I'll post diagrams which will let people eyeball the transfer windows, like I did for the Mun.

    -Would you mind sharing the formula you use?

    -I'v got used to this formula, its not the best... I'v picked it up somewhere a long time ago.. Modified it a bit..

    -Looks nicer on paper with roots and fractions, rather than a linear formula..

    zmDzF.jpg

    X= Target Orbit

    Y= Parking Orbit

    R= Orbiting body Radius

    |{|Square root|(X+r)^3]/Square root|(X+Y+2r)^3|}*180-180|=

    -It looks intimidating first glance, but its basically two orbital period formulas

    (one being your target, other the excentirc transfer orbit)..

    -Divided by each other to get the relative periods..

    (when one dose a full revolution the other one dose x % of that..)..

    -Multiplied by the 180 and subtract by 180..

    (to get the burn angle)..

    Simple as that.. :D

    Guys, this thread is dying. There are no news about 0.17 and no one knows when it's gonna be released. The pleasant anticipation is killing me, I checked this thread like 12 times today just to see a new picture from Nova. It eats my soul and infiltrates my dreams, it's a bad influence for my marks and my private life. It's a drug in my bottle rocketeers vains. I would like to hear a release date from the Devs, even it would be in 2013 or just a random date, so I could finally turn this computer of and sleep. :(

    -This is a good sign, it means that thy are working so hard so that they don't have time posting on the forums.. Patience..

    -We will have landings on all planets/moons in the 24 hours the update is released..
    I doubt every player will have landed on all the planets and moons within 24 hours of 0.17 coming out..

    I stated that some players will land in the 1st 24 hrs.. Not that all players will land...

    Its safe to assume that most of us will visit one, if not more of the new planets.. ie, achieve stable orbit around the planet..
