  1. Hi, as far as my knowledge goes, delta-v is not calculated with drag. Only without drag. The reason for this might because drag is highly depended on the flight profile (pressure, speed, rocket shape, ...). For Kerbin, there is a delta-v map (search for "Kerbin delta-v map" if you want it) which shows the delta-v needed for inter-planetary travel, incl. landing and ascent. The delta-v needed for LKO, for example, includes drag. For my rockets, I take a few hundred more because I know that my ascent path is far from ideal. If you want to know what your rocket's delta-v is, there
  2. Hello, is there a simulation environment for Scilab / CelestLab that can simulate rockets? My goal is to simulate a rocket’s ascent path and then execute the ascent path in-game with kOS. Same with a descent path – but first I have to get the rocket into Kerbin’s orbit. I have CelestLab installed with CelestLab on top but I can’t quite figure out how I can simulate a delta-v change. I haven’t found a function that gives me the orbital parameters after a delta-v change at any point on orbit. If I can't find a way, I will try to assemble my own simulation environment.
  3. Yes, I have one station currently orbiting the sun. In a few years, a maneuver node has to be executed to bring the station back into Kerbin SOI. Because I kinda forgot that there is some personnel on it. I still don't know how to brake the station but this is a problem for the future. The station's design is way outdated and is way to clumsy for operational use. Another two stations are orbiting Kerbin but without any Kerbals on them. I don't know what to do with them but I don't want to de-orbit them. The only useful station I have is a equatorial station that serves as a hub for travel
  4. It is possible to switch to any object that is in range, regardless of what type it is. I am not sure if it is possible to set the maximum debris count to 0. When you describe us what you are trying to do (e.g. the situation), maybe we can help.
  5. I think, on a space station around Mun or Kerbin. Not sure. Maybe on the ground, drinking rocket fuel. It's hard to keep track of all of them
  6. Hello. Can someone direct me to older versions? I need it to work with KSP 1.0.4. Neither TextureReplacer 2.4.13 nor v2.4.14 seem to work. I have placed new textures in the folder \GameData\TextureReplacer\Default\ and named them GalaxyTex_PositiveX, GalaxyTex_PositiveY, etc. Didn't work. Then I downloaded textures from someone else to test it and even placed just half of them. I took a few files and made them completely black but after the game load, there are no 'holes' in the sky. No changes were made to the .cfg files. I restarted the game every time I changed the files in t
  7. I tried to rebuild a Vega rocket and used this concept in career once. But it never had too much relevance to be used on a regular basis. Maybe when the satellite contracts come up more frequently but up until now it's mostly a little toys. And now, costs are not so much a factor now.
  8. I have two space stations orbiting Kerbin at an inclination of about 51° that are unmanned. Mostly because there's no science to be gained when at this inclination but it's harder to reach them. But it was fun to try to put them up there. I am still unsure whether I should de-orbit them or leave them for future use. A third space station with 0° inclination serves a real purpose as a pit stop between the surface and Mun. Several satellites are orbiting Kerbin, unsused. I once set up a GPS constellation of satellites, a space telescope, and some pseudo-communication satellites. I don't use
  9. Maybe. As an option to be selected in the difficulty menu.
  10. A similar observation involves not RCS but electricity. When I tell the craft to orient to prograde it will use more power to stay at prograde than telling it to go to prograde and then enabling attitude control (tapping "F" once). I think in the same way it uses RCS. This might be due to the inaccuracies of the simulation. If I need to look at power I usually switch to "attitude control" after orientation is done. With some minor corrections just before the main event.
  11. As far as I know, neither the direction nor the length of a strut influences the aerodynamic drag of a rocket or the force it can hold. This mean you could use only one single strut in a any way possible without making influence on aerodynamics.
  12. De-activating batteries and activating them again when the spacecraft is dead no longer works in 1.1.2. It was my preferred method to have a backup in case of electric starvation. Orientating the craft Normal or Anti-Normal (point the nose north or south) and putting 3 solar panels in radial symmetry on the craft makes sure that a little bit of solar panel is always pointing to the sun. That's what I always use. I haven't tested is entirely but I think that spacecrafts that are on rails don't use any electric energy in 1.1.2. If not, most of my probes are dead by now because they don
  13. That's what I mostly do. When I know that I have enough TWR I exceed this rule and come in hotter than usual. In addition to overlapping the speed marker and the target marker. So it's overlapping the speed marker and the target marker, and having 10% of the distance as speed (at 3'000m with 300m/s, adjusted for the situation accordingly).
  14. Up until now I never used the Thud engine, any radial engines, actually. The cases where I needed some kinda of radial engine, I used the LV45 Swivel and some structure parts. The Flea I only used during the first stages of the career. But since the Ant is little bit better (in 0.24 was it, I think) it sometimes ends up on satellites.
