  2. Jet engines work as normal in atmosphere. They need an air intake to work. Yes it's unrealistic. Breaking Ground props were explicitly coded not to work underwater. Yes, I think that's a stupid decision. Normal wing/control surface pieces WILL work as props when attached to Breaking Ground rotors. I's pretty fiddly, so most people avoid it. (I've never done it, and I LIKE fiddling with details.) Tips: A submarine is just an airplane in a much denser medium, so minimizing drag should be your primary design constraint if you want any speed at all. A jet sub that can do 20m/s seems to be a good average target, although I've gotten up to 40m/s on more optimized (but not outlandish) designs. Very few parts are natively denser than water, so making a sub sink is hard. The most commonly used one is LOTS of full ore tanks. I've ended up building a few subs in the 600-1000 ton range. I've not been able to maintain approximate neutral buoyancy with more than about an hour's worth of fuel. Once that gets burnt, you're headed to the surface without active control. There are design tricks/exploits you can do to have variable buoyancy. The primary one is clipping a lot of the smallest ore containers into a cargo bay. It works in reverse of normal physics, since the mass stays the same, but when you open the bay, suddenly the volume of all those ore containers is in the water and you float. I recommend using the Vessel Mover mod to get to the water from the runway, although trying to get there with wheels is a fun challenge.
  3. A scene where they actually do gold mass correctly:
  4. The mechanism is exactly as you describe it in World Out of Time, and he uses it twice, but the setting is different. I have the book and re-read the relevant parts this morning. We might be conflating two (or more) different stories. "Falling into a hole and discovering magic" is older than Merlin. My ex wife let me keep a big chunk of her extensive science fiction collection. I should call her and go bum some more.
  5. In the not-too-distant future these kinds of torturous odysseys of failed remembrance will be trivial to resolve. It will be a loss. Thus far I've dug into The Closet Of Dooooom to retrieve my two Saberhagen books, and speed-flipped through them to see if I can find any references. I've slowed down to devour a few choice chapters, then moved on to wikipedia to see if I can get a sense of which author would have written such a thing, or if any titles ring a bell. Thus far I suspect it was written somewhere in the 50s to the 70s, by one of the New Wave-or-adjacent authors. However, I recall the story being more prosaic than something that Delaney or Bester would have written. Somebody functioning in the space between New Wave and Golden Age SF. I've re-familiarized my self with quite a few authors who I now KNOW didn't write it. Taking a journey and chasing down rabbit holes and dead ends is fun and enriching. I hope people always find ways to continue to be driven mad by their own obsessive curiosity. In any case, if there's any two other people here who I think might know the answer, it's @Gargamel and @NovaSilisko. (Sorry for the ping fellas, there's a literary conundrum afoot--You know how it is.)
  6. I know I've read this, but it's such a common trope, I can't remember. My gut is saying Saberhagen, but I've never read the Empire of the East. Perhaps this event was referenced in the later Swords books, which I HAVE read. Otherwise, possibly https://en.wikipedia.org/wiki/A_World_Out_of_Time https://tvtropes.org/pmwiki/pmwiki.php/Main/LongevityTreatment https://tvtropes.org/pmwiki/pmwiki.php/Main/FountainOfYouth
  7. You Fool! RIP to one of the dirtiest, nicest men in Hollywood. (This is probably a SFW video.)
  8. I didn't read the news item, but I'm assuming they're intended to be at least partially sacrificial and rapidly replaceable. In which case we have our old friend, Elastic Failure. Band name, calling dibs!
  9. Hey FLAP YOU, buddy! Hey, I'm glad it worked. (I bet it would have taken off without the flaps ;P ) They've definitely changed some stuff since I last played (1.9ish)-The turboprops didn't have alternators, and the optimal AoA for all blades was the same. Did you have the aero debug options on? The PAWs will show lift AND drag from the blades. I still have never gotten dihedral main wings with incidence to contribute to roll stability in any configuration. I HAVE gotten a zero incidence T-tail to work with 5 deg ANhedral, because Surface Prograde tends to hold my planes a fraction of a degree nose-down. I set my abort button to undeploy the props. Magic airbrake.
  10. Your COL is still way too far back. Put it right on top of the COM and let SAS handle the stability. I think those engines decrease in mass if you set the max torque lower on the part (the electric ones do). Drop them to about 10-15%, they have PLENTY of torque. That should push your COM back to a reasonable spot. Don't bother with flaps in KSP, they just push your nose into the ground. If you have to, put some control surfaces on the leading edge that deploy upward. I think one of those icons is RCS Build Aid--Check your center of thrust by putting a tiny rocket engine on the axis of the motor. You can also get a better handle on the aerodynamics by temporarily taking the blades off and looking at the plane with CorrectCOL. Incidence + dihedral on wings is generally counterproductive in KSP. Anhedral vertical stabilizers is good to help the counter-roll issue from rudders. With props, max RPM always. Vary the torque to just barely keep the RPS maxxed. For blade angle, I build them as a flat disk, and deploy from 0 to about 65 deg. I keep a KAL linked to my throttle and do a linear torque from 0-100, and blade-pitch is 0-10% @ 0 deg, 10%-67% is 25-55deg with a slight curve. 67%-100% is 55deg-65deg, although most low-power builds can't get to 65 and it's actually counterproductive to go that high. So throttle ends up being about picking what's best for the speed regime, rather than just MORE POWER.
  11. Invited you to the PM conversation that contains the resources. I think once you've got your stuff dialed in, I might appropriate some of your methodology. It should be a similar process, just different things to optimize. Now to find the energy...
  12. I see we're still going with: "so glossy it looks like it has 2cm of ClearCoat on it." "enough light bloom to embarrass JJ Abrams" The recent fad of flat monochrome UI buttons still hasn't died, eh? Despite studies pointing to serious usability issues? https://www.nngroup.com/articles/flat-design/
  13. In case anyone doesn't know: Booots wrote Kerbal Wind Tunnel. Booots, speaking as someone who finds the thermal system the most interesting and challenging aspect of KSP, and has done a LOT of atmo-diving in planes, you can only handwave it in cases like Duna and Sarnus. That said: I would definitely limit your calcs to between 5 and 25 degrees AOA, for reasons I'm sure you're aware. Disregard the subsonic regime, since it's a discontinuity, and will be pretty much a rounding error on range. Inclination/course is going to be your second-most influential variable, due to the effects of centripetal acceleration. You will get wildly different ranges flying east vs. west. I don't know that this project has an operational utility (other than fun) given that one can stay in orbit for "free", and just re-enter later. If you're looking to use it to make big changes in landing latitude (as opposed to longitude), see my prior point. This is really similar to a project I shelved last year, seeing if I could calculate re-entry flight paths that minimize total heating, and/or max radiated wattage. I suspect there are some fascinating windows in there. I have the atmo/temp models, I just don't have the drive to get it done.
  14. I doubt you're going to find any freely-accessible resources. Professionally, I often have a hard time getting good high-res imagery / orthophotography. There's probably something down this rabbit hole: https://www.bellingcat.com/resources/2021/11/09/first-steps-to-getting-started-in-open-source-research/
  15. Hiya Hanson, There are quite a few trans kerbals, including two very good friends of mine. Of course, it's not my place to say who is and who isn't. You know, I went through a couple of years where I thought "transness" was weird and I didn't understand, but I gradually got over it through exposure, and now it seems like just another facet of the human journey of figuring out who we are. That's probably the most important and significant thing any individual can do, so it goes without saying that trans rights are human rights and should be defended. If you ever need someone to be really mean to anti-trans people, let me know.
  16. I can't find any good information on the cost of radial burns. In general, I think it's more efficient to adjust your time to intersect by changing your Ap or Pe; leaving radial burns for minor corrections. You might be able to derive it from Figure 4.12 on the Orbit Maneuvers section of this website: http://www.braeunig.us/space/index.htm
  17. Only if the cargo bay ISN'T your root part. There's a long-standing bug where the drag occlusion doesn't function in this case.
  18. Out of all the things I should have been banned for, and THIS is what you pick?!? Well then, I aim to misbehave. Back in college, I used to pull all-nighters to write my English papers. My performance-enhancement of choice was to take a 32oz Sunny D, drink the top 12oz, then pour a Pepsi in. Repeat 2-3 times as necessary. Yes, it's as disgusting as you can imagine, and it will all but guarantee you spend the hours of 6-7AM in the bathroom.
  19. It's a two-stage lasagna. I like asparagus and all, but "lasagna-staging" sounds like the ultimate evolution.
  20. Those are Jool-numbers. Duna should be MUCH less from low-Kerbin orbit. I will respectfully suggest that you have a planning/timing issue.
  21. Man, there's a lot to respond to in this, but I'll stick to the above: I have a somewhat contrary but complementary opinion (what's new?): You're right in that purity and single-minded purpose look much better on the young. In the old, it's tragedy and madness (King Lear?). I don't think that one has to LIKE the protagonist, just understand them. Time and distance and clarity of hindsight make for easier writing...and the issues are simpler. I don't think there's ever a point where we cease making mistakes, it's just that the attitudes and responses are different, and the demands and inertia are higher. It's more of an internal story, and the backdrop tends to be much less important. Setting and environment is probably much more fun to write. The older person just makes different kinds of mistakes, and I think the journeys of self-exploration are more intentional. As is the self-destruction, if one identifies something in the self that one thinks needs to be destroyed. I've not actually read his books, but I think this is something that Steve Martin (that jerk) writes the preamble to in Shopgirl. Writing prompt/character study: Sam Elliot-type. Full of "common sense" and gravitas, and surety. Until one day, someone asks him, "If you've got it all figured out, then why are you an alcoholic?" Actually, Sam Elliot has probably already done that bit, and if he hasn't, I bet Kris Kristofferson has.
  22. I've taken to minimizing the amount of oxidizer capacity, or just going pure-LF only. I enjoy the long, slow ride to orbit though. You'll probably be interested in Editor Extensions, RCS Build Aid, and CorrectCoL. Really useful for us spaceplane zealots. Links are in my sig. Have you tried a https://wiki.kerbalspaceprogram.com/wiki/Constant_altitude_descent? If I did my math right (arccos 305/800), you can point up to 67deg above retrograde with the Nervs before you have the same effective ISP as the Rapiers thrusting pure retro. By coincidence, that's about the starting angle you need to land with a local TWR of 1.1 (arcsin 1.0/1.1 = 65 deg).
  23. Huh. a Wolfe fan...somehow fitting. I've finished a couple of novels by Gene Wolfe. I've started a few more novels and never finished due to hitting the "I don't have a Master's degree in Literature" wall. Similar problem with the equally-sophisticated Toni Morrison, although I love her work. I've ready many of Wolfe's short stories, and the one that sticks with and haunts me is: https://en.wikipedia.org/wiki/A_Cabin_on_the_Coast I tend to stick to Zelazny, Vonnegut, and Le Guin, where I can at least intuit 90% of what's going on. Now you've got me thinking about why Severian is who he is... Even in his later years, I still see him as a lonely, isolated, and detached little boy. All the self-mastery and philosophizing in the world won't fix that. I think he does arrive at some Buddhist state of Oneness with the Universe, but I don't recall that he ever truly connects with another human being, or with himself. I think a lot of young men (myself included) go through a phase of wanting to be as detached and dispassionate as Severian usually is. What aspiring Sigma Male wouldn't want that professional career? Variations on Autarchy are often though as an end-goal of many philosophical systems (exs. Stocism, Libertarianism, MGTOW). Or as I like to call them, "Philosophies for adolescents by people desperately trying to prove they don't have mommy and daddy issues." Ultimately, chasing Logic, Virtue, and Mastery is about seeking approval and justification from the universe, and all of that seeking is fear-based. Adulthood comes when one can exist and be present without the burning need to know why. Anyone who doesn't try first is a flarping quitter, though. Sorry for the tangent, literature gets me thinking. I got about 1/3 of the way through Knight before putting it down. I think it's covering a similar very distinct phase of young-malehood. I should finish it, and get into Wizard, as I'm interested to see where it goes. Wolfe seems to be a firm believer in "necessary phases", and I don't disagree with him. I'll probably re-read Zelazny's Amber series first because I understood and saw the character growth more clearly.
