[00:49:16] https://i.gyazo.com/db3db762f14a0e26e30552d2ea73d4d4.png [00:54:53] beautiful [00:56:32] Flies like crap though, but it's possible to keep it under control. [01:01:20] so liquid fueled craft in stock are still a bit new to me. On second thought, I think this is worth asking about. [01:02:33] With boosters, I'd assume, roughly, boosters to get off the pad and ideally into fairly horizontal flight in the stratosphere. First stage to 1500ish m/s, and second (and a bit of the transfer stage) to circularize. [01:03:34] Obviously without, the first and second stage have a bigger job (though they're lifting a much lighter craft). Should the second stage still get into an intercontinental, if not quite orbital, trajectory? [01:03:56] To the point where you only need a small apo kick, like in RSS? [01:05:14] I know I could fly this craft and get enough science to do it "right", but pushing the limits is fun. [02:51:06] In stock, does relaying cost EC? [02:54:05] Sciece I think so, remote control I don't. [02:54:42] How many hours would it take a competent programmer, but woeful artist, to get familiar with making props? I'm thinking making cockpits for some of my vessels in my KSP career. Personalized cockpits to the vessels capabilities. I figure there is probably a learning curve, of maybe 5-10 hours. Unity and PropTools etc. How long does taking an IVA take, ~1, ~3, ~5, >10 hours each? [02:55:00] s/taking/making/ [02:58:34] NeverCast: there are some great blender tutorials [02:58:49] It depends on the person I suppose [03:05:24] NeverCast: it's not perfect (many many flaws, sadly), but I have a tool for importing and exporting .mu models to/from blender [03:05:48] https://github.com/taniwha/io_object_mu [03:08:52] Awesome! So that'll do exterior and interior modelling? Then I just slap some ASET Props on ? [03:11:32] taniwha: There is an open issue for IVA Props. Is that the interior view that is lacking? [03:12:14] interior views are done as separate models [03:13:00] that issue (#2) is about making it easier to place props in an internal model [03:13:10] ie, it will create the .cfg file for you [03:13:44] unfortunately, doing such in blender in a nice way is not something I've been able solve yet [03:14:35] hmm, however, I've got my hands on some interesting tools (hardops) that might provide some inspiration [03:14:42] taniwha: It can be done fairly interactively in Unity can it not? I thought I saw screenshots demonstrating that it should be laid out in Unity, my assumption was that the config was generated. [03:14:47] (just remembered /why/ I got them) [03:15:07] NeverCast: my goal is to remove the need for unity [03:16:24] taniwha: Are you focusing on RPM or MAS? [03:16:39] ??? [03:16:49] raster prop monitor? and what's MAS? [03:16:58] (and no, no focus on any mods) [03:17:51] It was my assumption that the layout of props was not mod independant. Is this incorrect [03:18:43] I'm not sure how to answer that. Even stock does prop layout [03:19:36] I could just be misinformed. I thought that some extra config work was required for non-stock props. [03:20:05] only in that you need to modify the configs in Squad/Spaces [03:20:16] ie, not really any different to creating new parts [03:20:31] RPM is just a very specific set of props [03:20:38] dunno about MAS, first I've heard of it [03:20:59] Alternative (and in some ways, a rewrite) of RPM: https://forum.kerbalspaceprogram.com/index.php?/topic/160856-wip-13x-moardvs-avionics-systems-mas-interactive-iva-v0120-27-january-2018/ [03:21:17] yeah, just found it [03:22:16] anyway, IVA prop creation and placement is independent of RPM or MAS [03:22:20] Things like the hitbox, guards, toggle switches, lights and "glowy" bits can be stacked together to create a single prop. That's the premise of it anyway. [03:22:33] though RPM or MAS will provide nice functionality for your props [03:23:09] fundamentally, IVA props aren't any different to parts [03:23:31] This is good to know. Saves learning the details of RPM/MAS for another day. [03:23:35] hmm... /that/ would be an interesting mod: an in-game IVA editor [03:23:41] ^ Agreed. [03:23:56] (not something for which I have the time or motivation, though) [03:24:27] Obviously still requires external modelling, but the placement and "Property Editing" of props in game would be, nice. [03:24:30] (nor I) [03:26:00] taniwha: Your tool. Can I pull in a stock part and tweak it's model from there? I'm assuming I can. [03:26:16] you can, within limits [03:26:18] I assume it's import/export in both directions. [03:26:36] many animations won't survive (textures, lights(?) etc) [03:26:55] but location/scale/rotation animations /do/ survive [03:27:22] Ah. Lights are in model data? [03:27:33] "textures, etc" What else is there? [03:27:38] ah, it looks like light animations do survive [03:27:45] I assumed most of it was in cfg. The model being, as it sounds, a model. [03:28:16] Light animations I assumed is a lerp between two textures. But again I've not worked on a prop before. [03:30:07] things like the animation of emissivity for engine bells [03:30:48] Ah I see. Essentially shader properties can have their values transitioned [03:30:51] That's stored in the .mu [03:32:12] yeah, shader values are in the .mu [03:32:57] Is the format of the .mu fairly "Modular", or is the format specific? i.e. Can you skip over the shader values, and then patch them in again when you export? [03:33:45] it's /fairly/ specific, but the actual loader/writer module is very separate (mu.py) [03:33:48] The format being some hierarchy format for example may allow part of the tree to be ignored on import, but rewritten on export. It'll take me a little while to derive the .mu format from your source [03:34:08] I've used it at the core of several non-blender utilities (all in the same directory) [03:34:31] so you can load a model, do some scripted tweaks, and write it out again [03:34:50] That means that MuEnum is complete then, nothing is discarded? [03:35:04] correct [03:35:06] Only that there isn't a Blender use for it. Gotcha [03:36:40] due to some blender specific tweaks being done to the data when loading (triangle vertex order, vector handedness), the load/save cycle isn't perfect [03:36:47] Animation has Clips has Curves has Keyframes ? [03:37:05] also, there were some bugs in the older versions of the format that my code cleaned up [03:37:14] I think so, yeah [03:37:23] I've forgotten the details [03:37:47] Well done on the implementation. It looks painfully tedious [03:38:13] I got some help from Mike (Mu) :) [03:39:17] If this could be broken in to a tree of values. That would probably be sufficient. [03:39:49] the loaded data becomes a tree of objects [03:40:04] Just no way at this time to see it in Blender. I understand. [03:41:09] What if the output from mu->blender drops blender model + tree file. Properties are edible in the blender->mu process? I assume you have a desired implementation already in mind tho [03:41:55] take a look at export_mu.py, I guess [03:43:08] Ah I see, MuObject is the tree nodes [03:46:28] taniwha: export_mu takes the blender info, builds the .mu. You have a collect animations. Where are they coming from? Nowhere at this stage? [03:47:01] blender's animation data [03:47:16] NLA strips etc [03:47:30] er, tracks [03:47:32] I've got confused along the way. What adata is lost? [03:47:38] s/adata/data [03:48:26] mostly non-positional animations (ran out of steam while figuring out how to translate between blender and mu) [03:48:33] hello [03:49:12] I've enabled Advanced Tweakables in this new save, but autostrut isn't showing up? 1.3.1 [03:49:28] How do I go faster in the atmosphere without burning up [03:49:33] ? [03:49:53] Aviatior101: Higher up, or radiators might help [03:49:55] Aviatior101, for what reason? [03:50:13] To circum navigate the globe [03:50:21] I was racing a friend [03:50:38] Aviatior101: Go to 22k, you can cruise comfortably at 1000m/s there, almost no heat [03:50:52] ok [03:51:19] also what is the best high altitude stock engine [03:51:32] is it the whiplash afterburner? [03:51:41] Whiplash doesn't have afterburner I don't think [03:51:51] Though at Mach 3.5ish, that's the fastest speed [03:51:52] oh [03:52:04] I've a dual Whiplash plane that does 1020m/s at 21.5k [03:52:14] isn't the whiplash the ramjet? [03:52:21] cool [03:52:32] I believe so, it's a high velocity engine. No afterburner [03:52:54] I made a concorde plane but afte pasing 1200m/s it would explode [03:53:02] Altitude? [03:53:56] taniwha: That sounds like your import/export is mostly done then. I'm not sure what you mean by non-positional. You mean animations that alter other properties, like the shader properties? [03:53:57] i don't know but It was the highest I could go without the engine losing performance [03:54:06] Let it lose performance. [03:54:13] ok [03:54:18] if you say so [03:54:22] If the air is thinner, as long as you still gain speed [03:54:30] yeah [03:54:47] NeverCast: correct, other properties [03:54:49] You're racing. Efficiency isn't really the point. [03:55:04] I guess [03:55:08] light intensity is the only non-positional property that works [03:55:20] (positional includes scale and rotation) [03:56:00] Aviatior101: At 22k, the Whiplash is only making about 40kN of thrust, each. But since the air is thin, you don't need a lot of thrust to maintain speed [03:56:14] yeah [03:56:42] I will just have to change my design so I dont lose altitude [03:57:00] Thanks guys [03:57:08] I have to get going [03:58:12] Faster is always the answer for altitude loss (Y) [03:58:19] Also idk why he isn't using RAPIER. [03:58:50] more importantly, anybody flying planes should use FAR [03:58:52] taniwha: Is the issue integrating it in to Blender, or understanding the format to begin with? [03:59:08] integration [03:59:09] Welcome back, use FAR, use RAPIER [03:59:31] I kinda hate that there are no options that are at all better than the rapier [03:59:44] Go faster. That'll keep your altitude [03:59:54] tawny-: You mean in stock? [03:59:57] haha [04:00:00] yeah [04:00:03] NeverCast: rapiers are overrated ;) https://www.youtube.com/watch?v=99pJQKyFi6k&t=1s [04:00:04] YouTube - Tobineko to Orbit [04:00:28] I always felt rapiers were under powered [04:00:31] tawny: Aye. But at 2100m/s you're probably trying to leave atmo. [04:00:47] Aviatior101: Go faster. Their power comes on around Mach 4 [04:01:19] (sorry about the tedium of the vid) [04:01:33] taniwha: 2.0x play speed [04:01:51] that would help :) [04:01:56] do engine precoolers do anything [04:02:44] Yes. They cool the engine. [04:02:51] Also I believe they are heavy. [04:02:54] do they ad power [04:03:03] *add [04:03:12] Hm. I can't accurately answer that one. I've never seen a performance/temperature chart for an engine [04:03:27] I figure, if it doesn't go over 99 percent max heat. It's fine [04:03:37] Aviatior101: I suspect they rob some power [04:03:53] really [04:03:55] They are intakes iirc. So they add drag [04:04:08] the point of precoolers is to prevent the engine from melting from compression heat [04:04:18] I thought that by adding more oxygen they add more thrust [04:04:36] ok [04:04:58] I know there was some changes around 1.0.2 that meant spamming intakes doesn't make your planes superhuman anymore. But I can't weigh in on the new mechanics because I haven't spent the time looking in to it [04:05:33] so I should keep them on my plane just to reduce the percentage of flamout [04:05:52] Honestly I'd advise testing it. [04:06:15] Get a plane auto-pilot, lock your vertical assent to +2m/s and timewarp [04:06:20] See what altitude it flames out at [04:06:51] Feel free to use faster ascent if your plane doesn't care. Just keep it the same for each test [04:07:01] ok [04:07:25] I will test that later [04:07:42] KIS question not answered in the manual: how do I bring an object along that says "Carrried by the kerbal" and "KIS Item Carried on: jetpack"? [04:07:47] I cannot put it in seat inventory. [04:07:53] I can put it on the craft, but that seems amazingly dumb. [04:08:04] Kramax Autopilot Continued, Aviatior101. It's auto-land/takeoff still needs baby-sitting. [04:08:07] Oh you left ok. [04:08:07] I can't put it on the kerbal in the crew portion of the SPH. [04:08:31] My favorite autopilot is Atmosphere Autopilot or something. Its fly-by-wire is sweet. [04:08:45] I'll look in to it. [04:09:13] As for your issue. Not one I've encounted but iirc, carried by Kerbal still needs to be stored in a kerbal accessable storage during flight. Retrieved by EVA [04:09:35] Sure. Isn't the seat inventory "kerbal-accessible storage"? [04:09:44] Yes, so is the storage pods [04:09:46] Or do I need to bolt a container on my plane just to hold this thing? [04:09:53] Depends on it's volume [04:10:10] Right-clicked the cabin, clicked 'Seat 0 inventory'. [04:10:17] I have an eight-slot inventory window. [04:10:21] Aye [04:10:47] I go to the science tab, click on SALLI the laser thing. [04:11:15] Drag it in to the inventory window? [04:11:17] what happens [04:11:33] It hides behind th einventory window [04:11:37] I did it three times just to make sure. [04:11:43] Did you drag or click and move? [04:11:50] Only drag works [04:11:54] Wrenches aren't working either [04:11:57] Okay, trying drag [04:12:07] Click and move is for placing on vessel. [04:12:38] Okay, Carriable items cannot be stored in the seat's inventory. [04:12:52] Can you put it in a storage pod? [04:12:57] or whatever they are called. [04:13:12] Make sure it says it can be accessed by EVA, I don't think it needs to be accessed internally [04:13:33] SC-62 Portable Container [04:13:40] I have to bolt this onto my plane first? [04:14:32] There is an inline option. But you can probably put it in a service bay also [04:14:38] Especially if you have TweakScale [04:15:05] Oh no. I need to put on a bracket. [04:15:08] No service bays here [04:15:24] You haven't unlocked them? [04:15:27] I have installed an SM-62 Container Mount. [04:15:39] If you have EEX, then pressing T lets you surface mount almost anything. [04:16:50] Also, once you get the item in to the kerbals inventory, it needs to be unstacked, then I think you right click and equip [04:16:59] Okay. I now have a giant stupid box on the spine of my plane. [04:17:04] Airflow sigh. [04:17:12] The giant stupid box has a single laser beam thing in it. [04:17:17] Just put the box inside the plane inside a service bay or something [04:17:30] I don't have a service bay. [04:17:34] Not unlocked? [04:17:39] That is correct. [04:17:47] Do you have any cargo parts? [04:17:50] No. [04:18:02] Are you using ferram aerospace? [04:18:31] If yes, clip it in to the plane with enough space for your kerbal to click on it. If not. Yes, Rip Airflow [04:20:31] hey does anyone want to have a casual chat about something in ksp [04:20:33] So for fun on the runway, I got out and tried to get the widget to put it on the backpack. [04:21:11] Mathuin: Let me know when KIS makes you rage. [04:21:19] Once you learn it, you rage less. [04:21:37] Right now I don't see how it could ever work. [04:21:48] What is KIS? [04:22:20] When I get the item out of the box, how do I put it on the kerbal? [04:22:36] ok [04:22:55] Mathuin: Drag it in to the Kerbals inventory to start, I think [04:22:58] Then you can right-click it [04:23:08] Also if you drop it. Use G to grab [04:23:18] Gosh I wish I knew Grab before I lost a bunch of batteries in orbit around Kerbin [04:24:20] Hi [04:24:34] Wat is this [04:25:26] hi Ksprocks [04:25:47] It is your friend [04:26:21] Hi [04:26:24] hi [04:26:26] Aviator [04:26:29] Yo [04:26:38] So wat is this [04:27:08] It is a live chat room to ask questions, give answers, and have fun [04:27:19] NeverCast: Okay, dragged it into the kerbal's inventory, and it's now my huge backpack. [04:29:11] When I go to *use* it, it says "Not enough ElectricCharge, shutting down experiment". [04:29:15] are there any mods with pulse jets [04:30:21] Mathuin: Maybe you need to rip a battery off the plane and carry that with you? haha [04:30:32] Or you need to charge it while it's in the vessel? I do not know [04:30:39] hello [04:31:11] Aviatior101: I don't know personally. But if you google "KSP Pulse Jet" you might get lucky. [04:31:23] ok [04:38:50] Searching the fine web for that string doesn't help. [04:39:02] Mine, I mean, not yours. :-) [04:39:40] I tried carring a battery, I tried putting the device on the ground (which makes the motions look right) and putting the battery on it, nothing worked. [04:42:50] O M G [04:43:00] I just bolted it onto the plane, and it worked. [04:45:59] I guess if I *had* a service bay, I could store it there, take it out, put it on, get the science, then put it away. [04:46:05] But that seems a little insane. [06:01:51] "xor edi,edi" XORing the same register doesn't seem like the most efficient use of time, Visual Studio... *chin scratch* [06:10:14] Neal: I think it's a cheap way to put a zero into a register [06:10:54] https://stackoverflow.com/questions/33666617/what-is-the-best-way-to-set-a-register-to-zero-in-x86-assembly-xor-mov-or-and [06:10:58] ["TL;DR summary: xor same, same is the best choice for all CPUs. No other method has any advantage over it, and it has at least some advantage over any other method. It's officially recommended by Intel and AMD"] [06:11:09] ^ confirmed [06:12:24] looks like I need to pick up a book on asm optimization [06:13:15] alternatively, have a peek at how compilers turn intermediate representations of a program into compiled code [06:13:43] like - it gets compiled to an IL before being turned into the specific instructions [06:13:59] that last step is a lot of dark magic [06:15:10] il = intermediate language? [06:15:13] aye [06:15:50] like java bytecode or .NET / mono assemblies, I think [06:17:29] either way is fine - compilers are full of dark magic, but various script engines like V8 (node.js and chrome) are doing low level optimizations too [06:19:28] http://jayconrod.com/posts/54/a-tour-of-v8-crankshaft-the-optimizing-compiler - ["in this final stage, Crankshaft emits a sequence of native instructions for each Lithium instruction."] [06:21:11] before that, there's yet another representation (the first abstraction in V8 before it turns into lithium is called hydrogen, apparently) [06:21:39] too much dark magic - my brain just noped out of this topic. sorry for biting off more than I wanted to chew or comment on :( [06:23:25] http://mars.jpl.nasa.gov/msl-raw-images/proj/msl/redops/ods/surface/sol/01949/opgs/edr/ncam/NLB_570519386EDR_F0680000NCAM00289M_.JPG [06:25:53] Came so close to Mun orbit without nodes. [06:26:09] you can go there, land and come back without nodes [06:26:18] https://imgur.com/a/XHN2T [06:26:18] https://i.imgur.com/wrxUY0L.png [06:26:31] that is way too far [06:26:51] the usual� way to do it is to start injection burn when the mun rises on the horizson [06:27:07] then you will be at your apoapsis when the mun is there too [06:27:31] Since it's at double the period? [06:27:47] double of what [06:27:54] of the transfer orbit [06:28:03] i should know that... [06:28:05] Neal: good luck [06:28:14] i dont know, never looked at that [06:28:31] either way, though, I was aiming for when the mun rises, but trying to guesstimate from map view to also watch the orbit. [06:28:39] issue was more a bad gravity turn [06:28:56] I think I have the option to take an asm class next semester [06:29:14] (more an over cautious one, but generally FAR doesn't seem kind to long 1.25m designs) [06:29:25] yesterday was tough. day 12 full in swing, all the mun and minmus missions running in parallel, i still havent run out of the 10 minute nodes coming up constantly as i finish the previous. they are so close i cant even launch new ships [06:29:37] dang. [06:30:04] i even postponed the current mun landing [06:30:57] I've been coming up with all kinds of fun goals, but I'm just glad to have Jeb and Val at their first star [06:31:35] I could sit in this orbit until the Mun reaches it at the same time, but I don't think I have enough spare delta-v to enter orbit and still make it back. [06:32:10] if you have enough for a flyby you have to do it the free return trajectory way [06:32:20] unfortunately for that you need the maneuver nodes [06:32:29] kuzetsa, OR eax, eax would probably set the register to 1 right? [06:33:00] wait no [06:33:07] wrong [06:34:08] high space eva/crew report collected [06:34:45] I am proud that even in my FAR induced disassemblies, there's been nothing that would have led to crew loss. [06:35:12] Generally they were supersonic, but a drogue and main chute on a mk1 pod is plenty [06:36:35] Ooh, and Mun was nice and helped me get home. [06:36:36] https://imgur.com/a/UNRju [06:36:37] https://i.imgur.com/Bi3gvr8.png [06:37:13] I think a bit higher periapse would be safer. [06:37:41] my usual goal is to launch the first mun flyby mission on day 1 [06:39:38] ok, so how do I raise my periapse when I'm already past apo? [06:39:51] radial burn [06:39:56] not as efficient [06:40:12] or rather a combination of radial and prograde [06:42:54] still have a fair amount of fuel, got to a 36 km x 10.3 Mm "suborbital" trajectory. [06:43:19] have heatshield? [06:43:28] yes but no ablator [06:43:32] it'll be fine. [06:44:23] I wasn't as worried about heat, as coming in so steeply that I didn't reach terminal velocity in time to open the chutes. [06:44:53] for that i use the small drogue chute [06:46:48] yeah, I want to say I've been using that around 10 km [06:47:27] Pakaran, if you have maneuevre nodes open you can set up one and then play with prograde and radial handles to get periapsis higher [06:48:55] Gasher[work], that's on the list to get. This is, like, launch 5 total I think. [06:50:01] ah ok [06:50:03] VAB parts limit isn't bugging me as much [06:50:25] it's maneuver nodes I miss from science games. Not money as such either. [06:50:35] 30 parts is a bit tough for the first mun landing [06:50:49] but it is ok for a flyby [06:51:20] especially with beginner parts and the weight limit of the launchpad [06:55:19] launchpad is upgraded [06:55:46] things are a bit harder in the hard mode settigns [06:55:53] so I'm figuring to next get some 2.5m parts (and, particularly, long fuel tanks) [06:55:58] because you earn less money? [06:56:00] all the research an the upgrades are expensive [06:56:37] I've definitely done things specifically to get money, but it's more often that I see a mission that looks fun to try. [06:56:46] but ultimately because i am juggling a dozen missions in parallel, the income is high [06:57:25] next big is 10 tourists mun landing. maybe i do 3 hitch hiker containers and add 2 of my own too [06:57:54] bob is way out at minmus, pioneering the science [06:58:18] but since it took him days to get there, i got 2 new instruments [06:58:20] no, 3 [06:58:30] but only 1 is missing [06:58:50] but for that i still need millions for the science building upgrade [07:01:13] https://imgur.com/a/rpXut [07:01:14] https://i.imgur.com/pxjyel2.png [07:01:23] yep val will be fine, even if she does lose the drogue shoot [07:01:40] chute* [07:02:30] just a matter of waiting to see how much money we got for records... [07:23:01] Hmm, tourists to Kerbin orbit. might be a nice test for the rescue craft... [07:25:18] beware that long return craft can wobble and turn the wrong side to the atmosphere [07:26:56] hmm thanks [07:27:17] at the moment it'll be a pod with a probe core, then think about combining rides etc... hmm... [07:34:03] thinking I want aviation. I'll get more science parts later. [07:34:17] hardly behind the curve, and planes sound fun (science car?) [07:38:26] Pakaran, science flyer+car [07:38:33] This looks tempting for money. https://imgur.com/a/3146i [07:38:33] https://i.imgur.com/E81nl1L.png [07:38:50] hmm. [07:39:23] a flying science car could get to the mountains west of KSC, too? [07:40:10] it can get anywhere if the landing zone is flat enough [07:40:33] also beware that takeoff velocity usually exceed the wheel max speed [07:43:32] thanks. [07:43:52] check those etc [07:44:26] one way is to make landing wheels longer when unfolded, take off on them, land then retact them and drive on rover wheels [07:45:25] Hello! Is any body here? Need help with my spaceplane. [07:45:40] hi rat :D [07:47:01] Nezumi [07:48:07] I'm gona find somewhere to upload my design. [07:49:26] Here is my spaceplane https://ibb.co/hV3966 [07:50:16] And I went with stock ksp without F.A.R. [07:51:39] I'm using Kramax autopilot, it's good until I reach to 1 mach. [07:53:04] The plane kept nose up and down. I can recover this by disable autopilot and active S.A.S. [07:54:39] Dose any one know what I did wrong? [07:56:16] Gasher u still there? [07:56:24] damn [07:56:30] sorry gtg [07:56:32] Nezumi: Sounds like your control surfaces are too agressive [07:56:35] at high velocity [07:56:42] Pakaran, or this https://i.imgur.com/jpJ8zxz.jpg [07:56:55] That and the PID in Kramax is over compensating. [07:57:34] If you can do several G manuvers with your control surfaces, have less of them, or limit their deflection. [07:59:03] NeverCast: Indeed I tried 11G turn and it works. [07:59:39] So it is way too much than what I need. [10:38:35] Did not know this was a thing! https://forum.kerbalspaceprogram.com/index.php?/topic/137293-wait-caps-lock-does-something-in-ksp/ [11:55:07] so my dude doesn't have a lathe but I can probably use my press drill and amke a wooden former for my nozzles [12:17:37] #KSPOfficial: mode change '+o APlayer' by ChanServ!ChanServ@services.esper.net [12:18:10] so I made this based on guidelines I found on the internet but that diesn't look optimal https://cdn.discordapp.com/attachments/405528003997859842/408234426804469760/rocket2.jpg [12:18:24] but then I guess rocket candy doesn't generate a super high presure [12:19:11] AFAIK most rocket candy boosters don't have special nozzles at all [12:19:32] People just stuff it into a pipe and leave some room at the end to act as a "nozzle" [12:20:05] I found stuff like that https://www.nakka-rocketry.net/knight2/desfig1.gif [12:20:16] and I followed those guidelines http://www.jacobsrocketry.com/aer/designing_rocket_motors.htm [12:20:24] Uh what [12:20:30] A concrete nozzle? [12:20:47] yeah because those peoples don't care about weight apparently [12:20:56] gonna make mine with plaster I think [12:21:04] at least the test ones then I will see [12:21:16] What about a sheet of tin or so? [12:21:27] harder to make I guess [12:21:34] But concrete [12:21:52] Sounds... sub-optimal [12:22:27] at least it's somewhat strong [12:25:07] I have doubts regarding what will happen to a blob of concrete surrounded by, presumably, plastic, heated to a few 100 deg C and violently shaken [12:25:48]
