[02:57:00] #KSPOfficial: mode change '+o Althego' by ChanServ!ChanServ@services.esper.net [02:58:20] zombanwa [03:03:39] That feeling when you [03:05:58] astronomers being silly, I think. (or is this one of those ultrahard SF articles that sometimes shows up?) https://arxiv.org/abs/2106.15181 [03:07:11] because it was not hard enough to beuil a dyson sphere around a star. no, build it around a black hole [03:07:18] there's no way [03:11:21] Like I said, sometimes papers on arχiv read like ultrahard SF [05:12:15] wait, there wasa virgin orbit launch [05:23:26] the roll oscillations seem to be better than the first time [05:35:10] Althego, hi [05:35:16] ho [05:35:37] lo [05:35:49] raptop, hi [06:35:33] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [11:35:55] 1337 [11:38:12] oh no [11:46:09] . [12:09:01] Action: darsie discovered he can trim his rover to drive forward unattendedly. [12:10:16] btw did you know there is now a separate ground throttle and airplane throttle? [12:11:03] no [12:11:31] the problem was for me, sas is coupled to car forward [12:12:11] so constant sas on-off [12:12:49] Dang, I accidently increased time warp than decreasing an flipped over. [12:13:07] that is why serious people use planes :) [12:13:23] at least now we have the space boat dock in ksp [12:13:33] so you can legit build boats [12:13:37] even if they dont work well [12:13:58] Hmm, maybe I can land a plane in the mountains and scan a huge quartz with an OP-E arm. [12:14:16] that is what i tried once [12:14:21] was total pain [12:14:25] :) [12:14:29] landing is almost impossible [12:14:39] not that rovers like 45 deg slopes [12:14:57] and then even if you landed, you need to get really close to the crystal thing [12:15:09] with a vtol it is probably possible [12:15:14] not with a normal plane [12:15:44] I landed with planes on mountains. Not high inclination, though. [12:15:57] Dunny if my planes are normal :). [12:16:07] yes i did too [12:16:09] on top [12:16:12] mhm [12:16:16] the crystal wasnt there [12:16:20] shh [12:16:24] :) [12:16:34] Hmm, I could search for it with a plane. [12:17:32] and/or drop a rover with a chute. [12:17:59] Electric plane :) [12:21:08] electric eye [12:26:32] It's silly to have the mount points on the motors vertically and the props are horizontally. [12:42:45] why do rockets need those high towers? for example what spacex is building now. why not just dig a hole and sink the rocket in? and if it explodes that also protects the surroundings [12:43:22] Althego: going down is always much more expensive than going up. [12:43:54] interesting i didnt know that [12:45:44] well, think about it. They are near an ocean, so the ground water is probably very low (and probably even salty) [12:45:52] so you dig a hole and have to pump out the water constantly [12:46:04] then you need to reinforce the hole [12:46:09] and where to put the stuff you dig out? [12:46:26] Maybe there's rock underneath it, it's 100 m you wanna dig down. [12:46:31] You have to get rid of that rock. [12:47:03] Colin Furze has dug a tunnel under his shed. Look him up and see how long it takes to dig just a bit down. [12:47:11] i know [12:47:26] not a fan of his, but saw some videos [12:49:43] other problem would be you have to get rid of the exhaust under ground. lead it up to the surface [12:50:08] i guess you cant ever make the hole water proof [12:52:33] Oh, you can [12:52:47] concrete can be built watertight [12:53:02] but you will get rain in. [12:53:12] put a lid on top [12:53:27] now you've got a bunker for an icbm. :D [12:53:35] yes [12:53:40] they could do it [12:53:57] but i didnt take into account they had infinite taxpayer money [13:29:07] !calc 30000/60/24 [13:29:08] Althego => ~20.83333333333333333333 [14:00:52] wait, what [14:01:47] 20 days [14:01:49] yes [14:01:51] :P [14:01:53] no, hours [14:01:58] or days? [14:02:00] 30000 records, takes 1 minute, so hours days [14:02:00] days. [14:02:02] oh no [14:02:06] 20 days [14:02:18] 20 days to delete 30k records from the db [14:03:53] but this is an estimate, some records are kept. so it may be only 2 weeks :) [14:07:42] !calc 2/3*300/24 [14:07:43] Althego => ~8.33333333333333333333 [14:07:56] good, may be only more tha na week [14:13:30] Althego: I think rocket exhaust would interfere with the rocket too much in a hole. [14:39:07] Why does my CCW motor with CCW blades produce negative thrust? [14:39:54] heh [14:39:57] complicated [14:40:06] you have 3 things you can invert [14:40:09] the rotation [14:40:13] the blade type [14:40:26] and the deploy angle [14:40:35] and you have to play with all 3 all the time [14:40:42] Hmm, leading blade edge is on the back. [14:40:54] Do I have to set negative deploy angle? [14:41:05] at least that is how i do it [14:41:12] i invert everything until it looks right [14:41:18] as a real prop would [14:41:27] so lower angle of attack on the outside [14:41:43] the leading edge in the right direction [14:41:47] and the angle of attack positive [14:43:07] and for that you have to use the paw of the motor to rotate direction (you can do it two ways), then the prop paw to switch to the other model, and then the deploy direction [14:43:25] incredibly cmplicatd [14:43:36] in an ideal world just selecting mirror symemtry would take care of this [14:44:25] i am in a circular orbit of 200km altitude. how much deltav would i need to raise my apoapsis to 300km? what's the formula for this? a link or search term would do [14:44:41] not much :) [14:44:44] :D [14:44:57] the game calculates it for you if you have maneuver nodes [14:45:06] yeah but i wanna calculate it myself [14:45:16] i think there is something in the wiki [14:45:31] if not, some of scott's old videos had orbital mechanics [14:46:55] i think it is NOT in this https://wiki.kerbalspaceprogram.com/wiki/Cheat_sheet [14:48:37] i think that has to do with rocket equation [14:48:53] there is a deltav map there but i'd like to be able to calculate those numbers myself [14:48:59] for any arbitrary orbit [14:49:08] that is not so simple [14:49:14] even these values are mostly measured [14:49:18] or simulated [14:49:54] for example the delta v between solar system bodies changes based on the time you do it. the bodies could be in better or wworse position [14:50:23] leaving the atmosphere can also be different between ships, since tehy have different twr and drag [14:50:41] however calulating the delta v required between two ellipses [14:50:59] i think you want to look into hohmann transfer [14:51:32] there were some square roots in it, i dont remember :) [14:51:55] https://en.wikipedia.org/wiki/Hohmann_transfer_orbit [15:04:49] nah [15:04:52] .1!!!!1111 [15:05:04] just needed to turn away for a day [15:16:33] Althego: Higher AoA outside. [15:16:56] no, lower. because it moves with higher speed [15:17:08] highest aoa at the axis [15:17:14] Deploy extended vs. retracted helps, too :). [15:17:44] Actually it's the same AoA everywhere, ideally. [15:23:36] I don't get it: https://i.postimg.cc/px9SmWT2/screenshot61.png [15:23:56] one arrow points backwards [15:24:07] that is how it visualizes me too [15:24:20] but as long as the plane is not trying to go to one side, it is ok [15:26:25] https://i.postimg.cc/xfP1Hvgz/screenshot65.png [15:27:04] It's moving slowly. [15:29:01] Props are moving in opposite directions with correct AoA. [15:30:01] I might have to mount them wrong to get it working. [15:31:23] ti think the yellow would be the prop thrust [15:31:33] red is drag [15:31:43] green is dont know what, probably torque [15:31:49] thrust [15:31:59] no, because one points backwards and that is fine [15:32:02] so it cant be thrust [15:32:17] It is thrust, and it's wrong on the *right* engine. [15:32:57] no, on the left engine. [15:33:46] it looks like the deploy direction thing vanished from my plane and it works fine [15:33:52] cant imagine what happened [15:33:58] maybe they removed one layer of useless complexisy [15:34:15] and i typing is worse than usual [15:34:37] anyway, the yellow thing is important. because it changes size with you speed [15:36:20] the green seems to be steady regardless of motor torque applied [15:36:29] but when i take away torque, the yellow shrinks [15:36:39] and in fact can point to the other direction [15:36:48] so it seems to be more important [15:37:30] then the green is angular momentum or something like that [15:37:44] and that would explain why it is pointing in the other direction [15:44:09] Maybe I attached the blades on the wrong side. [15:47:05] Hmm, both motors accelerated forward. Maybe it is torque. [15:47:08] the green [15:47:38] After all, motors don't produce thrust. [15:48:38] Blades might be stalling. [15:49:57] blades only produce thrust if they are deployed [15:50:05] regardless of how they look in the picture [15:50:30] by default they are not deployed [15:50:34] I'm flying.3 [15:50:37] -3 [15:50:54] it is useful to have them undeployed, because you can glide farther that way. i think it is the equivalent of the feathered position [15:53:06] Yellow is thrust. [15:55:24] No clue what the pink stuff is. https://i.postimg.cc/fwbbX2JQ/screenshot67.png [15:55:53] that may be control surface [15:56:20] because these blades can handle controls, and by default it is on [15:56:41] probably more useful on a helicopter [15:57:52] hmm ,but usually yellow is control [15:58:01] what is purpkle then [16:14:31] the purple only shows up on props. I _think_ it has to do with their virtually increased length and "forward lift", mumblemumble [16:14:50] ( https://formularfetischisten.de/~packbart/temp/kspa1.jpg / https://formularfetischisten.de/~packbart/temp/kspa1.mp4 ) [16:15:06] virtual increased length? [16:16:05] yeah, I don't find the explanation on the forum anymore, though. a dev explained that for physics calculation, the blades are longer than their visual appearance [16:16:12] Action: darsie found quartz. [16:16:16] lol [16:16:34] what? :) [16:16:59] so the purple is showing the tips or what [16:17:53] looks like it. man, I seem to remember reading an explanation for the colors but don't find it... the Internet is too deep :) [16:18:30] there's a mod to automatically adjust prop angle, too. "Pitch Perfect" [16:18:50] yes, it is kind of hard to fly with two throttles, so i usually fix the angle [16:19:01] in a compromise position [16:20:35] ( https://forum.kerbalspaceprogram.com/index.php?/topic/199464-x ) [16:24:01] the virtual length was a workaround for some limitation in the Unity physics engine [16:24:44] "The propellers, and to a lesser extent the helicopter blades, calculate their velocity/AOA from an artificially offset position. This allows them to act like they're at a higher RPM than they actually are, to get around the PhysX RPM limit, with the consequent effect on AOA, drag, and lift." [16:24:53] ( https://forum.kerbalspaceprogram.com/index.php?/topic/186073-ksp-loading-preview-breaking-ground-propeller-and-helicopter-blades/&do=findComment&comment=3631881 ) [16:25:29] grmbl [16:30:50] "If you truly have faith, you will be lifted by the Krakens arms!" :) [16:32:51] Action: raptop sets the kraken on fire and shoves it through a converging-diverging nozzel [16:48:23] so that is what people call a kraken drive [16:57:25] Action: darsie took a screenshot of quartz and crashed. https://i.postimg.cc/KxdR7tCs/screenshot76.png [16:57:45] hehe [16:57:49] at least you have coordinates [16:57:55] very ince location, flat [16:58:18] I'll fly there again and land. [16:58:46] Flys pretty nicely, now. [17:02:41] so china wants a manned mars landing on 2033 [17:02:47] in [17:03:07] i wonder if this kill sartemis [17:04:13] AIUI, China hasn't made any sort of formal announcement, and the 2033 date is just one study [17:04:52] ah [17:07:09] https://www.youtube.com/watch?v=XqPOe45VzK0 some tiny launch [17:07:13] cant watch it [17:42:00] Yess! I landed next to the quartz. Well, somewhere further away, but I rolled there, then. https://i.postimg.cc/3r5N2vSH/screenshot87.png [17:42:15] Slow touchdown is ke. [17:42:18] key [17:42:45] Should use flaps if they are available. [17:42:58] they are always available [17:43:09] even you dont have the control you can use the paw [17:43:19] paw? [17:43:31] Hand? [17:43:39] part action window [17:43:42] or whatever it is [17:43:45] the context menu of the part [17:43:51] you can always click deploy [17:43:57] even if you dont have action groups [17:44:04] ok [17:44:16] and if you have the basic action groups... the abort group is almost never used. :D [17:44:32] yes, abort, gear, and such [17:45:04] 23 km rove ... [17:45:09] at least rockets dont usually have gears or legs, so i can just bind antenna and solar panel deploy on it [17:57:17] oh no, phoenix at 10. and tomorrow morning is already olli's math stream [17:58:17] Action: raptop was confused for a moment, given that the phoenix lander arrived at mars 13 years ago >_> [18:13:04] Action: darsie scans the quartz: https://i.postimg.cc/37RvhXpd/screenshot91.png [19:26:46] Action: darsie needlessly accepted a 10 MVF contract. [19:27:23] \F [20:19:46] E:D does have some interesting disco lights... :> ( https://www.twitch.tv/cmdr_emulatedpenguin ) [20:22:22] well, now it's gone. many ships pointing beam lasers at a poor Thargoid alien [20:31:27] packbart, whos ed [20:32:51] it's mostly a space shooter. Elite Dangerous. no orbital mechanics involved [20:33:13] space shooter as in shmup? [20:33:26] the ships have magical electrical thrusters and FTL drives [20:34:30] minas_tirith: well, ramming is an option, too [20:37:01] I just wanted to point out the mesmerising view of colorful beam lasers and at that moment they stopped shooting [20:37:10] ah, it's on again [20:38:38] Is there a volcanic activity mod for KSP? [20:38:58] Having my base destroyed because I accidentally landed it in a volcano would be fun [20:40:19] Action: raptop is reminded of 0.17 Moho's atmosphere [20:40:42] FLHerne: switching between planet texture quality levels does have that effect :) [20:41:18] Action: flayer slaps packbart [20:42:41] The Fish-Slapping Dance? [20:48:49] pretty much [20:49:00] i dont have mirc anymore but i still like to slap people [20:51:03] Action: raptop slaps a trout with flayer [21:45:29] poor trout.
