  1. And one with bold ISA: Credit to Cydonian Monk for the kerbal image.
  2. Cydonian Monk's image design with the career name I always use. ISA
  3. So I registered on the squad bugtracker. Does an admin have to add me so I can login?

  4. Just a tip, put your RCS thrusters farther from the center of mass. It would take about 1/4 of the monoprop to rotate that if they were on each side. Of course, translation would still cost the same.
  5. This is a silly question isn't it? It depends entirely on your rocket's TWR and the destination. First of all, the most efficient parking orbit, is to not have one at all. Just burn straight into the transfer from the launchpad. But of course, it is much easier to use a parking orbit. The next best thing is to transfer from a low altitude of 69,078 meters. Then again, you can't have a TWR of infinity, and it is more efficient to burn along the maneuver node instead of the prograde. You'll have to set a parking orbit altitude higher based on the time it will take you to do the maneuver to prevent your rocket from going into the atmosphere again. You can improve your TWR efficiency and prevent dropping into the atmosphere by doing several orbits on the transfer burn too.
  6. Other: Some kind of limit to antenna range or a remote tech type of thing. Right now, there is no reason to not have the lightest antenna. Right now, the small difference in the time it takes to send data is hardly a motivation.
  7. Thrust to weight. The in-flight TWRs are dynamic with local gravity and altitude. The launchpad TWRs are what you would see as if it was on Kerbin's surface. I can add the calculations later. I'm on mobile now. to rkman: It isn't a whole lot different. I'm working on it next, but I'm guessing the velocity difference for a 10 deg angle would be 1.015 times the terminal velocity. 1.41 for a 45 deg angle. By the time you get to a 45 deg turn, I hope you aren't relying on these numbers anyway. The fuel and engine mass for such high TWRs isnt worth the gravitational losses.
  8. TriggerAu will decide which ones he wants to add. I'll make a few specifically requested ones from him for the mod too.
  9. These guides will eventually cover everything from the very basics to the most advanced stuff. http://scottkerman.imgur.com/ Basic Orbital Maneuvers covers what an orbit is and how to get into one. Intermediate Orbital Maneuvers covers the most efficient ways to travel to the moons. Advanced Orbital Maneuvers will cover interplanetary travel, docking, and optimal ascent profiles for each body. Basic Plane Design covers the very basics of building a stable and controllable plane. Intermediate Plane Design covers spaceplane design and will have more to come. Advanced Plane Design (not completed yet, waiting for aerodynamics update) Basic Rocket Design covers the very basics of rockets. Intermediate Rocket Design (working on it) Advanced Rocket Design (not completed yet)
  10. I did some calculations for optimal TWR assuming your rocket has a coefficient of drag = 0.2 (Which is almost always the case in v.90) TWR and Ascent Velocity Charts I plan on adding one for each atmospheric body you can land on. Non-atmospheric bodies have an optimal TWR of infinity as you may already know. Link to the guides these come from. They aren't complete, so you wont see all of them yet.
  11. I'm toying with a delta-v map layout. Take a look at what I'm thinking about: If the numbers look different than what you're used to seeing in delta-v maps, it's because they are based off of my old personal notes. EDIT: The distances are scaled logorithmically by delta-v. EDIT: New image with red arrows.
  12. TriggerAu, this is looking really good. If anybody has any questions or comments for the images, I'm the guy to contact. I'm only like 20-25% done with what was my original plan for them, and the ones that are up are still getting some love. If you think of something to add or find something confusing or just plain wrong, let me know. It's been awhile since my studies in orbital mechanics and engineering. Anyone can message me on reddit. I check there more often: http://www.reddit.com/user/ScottKerman/
