[05:05:54] my parents said ksp would never help me... well here I am designing a rover to deploy out of a high power rocket for a nasa competition [05:06:44] and how does all this help you< [05:06:47] ? [05:09:02] I guess not that much but I did make a lot of rovers deploy from rockets in ksp [05:09:28] from rockets? not drom landers? [05:10:27] for the competition the rocket flies with the rover in the payload bay, deploys a parachute, lands. rover is pushed out of fuselage and is free to drive around [05:20:42] eh...? [05:20:54] I did a 6 wheeled rover 'truck' outof a rocket. [05:21:03] landed with a a rocket pack [05:27:51] JVFoxy, is this real life you're talking about? [05:28:03] bc if you did powered descent I'm very impressed [05:28:10] hehe [05:28:14] that must be ksp [05:28:31] wait.. you talk'n about real life landing a rover sorta thing.. or in game? [05:28:41] he is talking about a real one [05:29:07] making a real life rover [05:29:11] I'd love to do real world lander.. just .. no funds [05:30:10] my case... was mostly an in game reference. I tried doing like how Russians did with Lunakod.. but then just a frame that had rockets that would disconnect on landing [05:30:53] someone is doing powered descent with hobby rocket motors [05:31:19] don't those need o2 to operate? [05:31:29] runs on apcp [05:31:35] same fuel as space shuttle srbs [05:31:51] on solid rockets? [05:31:53] that must be hard [05:32:01] ya but... according to instructions, to deactivate/dispose of them, immerse in water. [05:32:40] Surveyor landers did it on solids... at least part way [05:33:39] if you know exactly how much impulse you will get out of the motor it's doable... I doubt consumer grade motors are that reliable... guess I'll find out for myself soon [05:33:47] this is my favorite rocket video to date https://youtu.be/rbO7fXBad3o?t=10s [05:34:43] alternate angle https://youtu.be/2n_0PLoksDc?t=1m20s [05:36:46] there is some slight fudging on SRB figures.. even liquid ones.. just means have to allow for some leeway. [05:37:15] 'acceptable tolerances' [05:37:40] that's definitely not what you want when landing =P [05:38:25] any error in the fuel directly correlates with how hard you hit the ground [05:39:01] not unless you built it into the design... as with Surveyor.. it stopped engines a short distance up, costed down. It was design to land like that [05:39:58] depends on the gravity of the body you land on... if you stop moving one second before landing on earth... you're going to crash down going 9.81m/s [05:40:14] if the craft is fragile... [05:40:57] I'd wager shock dampening is more important [05:41:16] on moon, 1/6.. so going only 5.3kmh [05:41:51] well Surv had crush pads, shocks.. [05:46:04] anyways.. [06:44:17] yes thank you windows for rebooting without warning [06:44:23] not evne 30min notice [06:46:53] well at least chrome kept my tabs [06:59:32] had that problem with my laptop... middle of something, nope gotta shutdown, install updates. Needless to say, I went through all the settings so it worked how I wanted [07:02:44] JVFoxy: Yeah you have to use the GPedit.msc its so annoying [07:02:58] nah [07:03:06] just tell it you on a metered connection [07:03:14] well one of things you can do [08:05:26] the worst is when it decides to install updates when you turn on your laptop to work on something in class [09:06:16] heh windows rebooting is why I dont have windows anymore [10:37:30] #KSPOfficial: mode change '+o Deddly' by ChanServ!ChanServ@services.esper.net [13:40:09] Last message repeated 4 time(s).

[15:49:43] well larger slower props are more efficient [15:49:56] because you do the same amount of work on a larger area [15:50:54] many ships have fan like screws to reduce cavitation and lower the rpm and reduce fuel consumption at lower speeds [15:51:13] water is also much thicker than air [15:51:18] queen mary comes to mind [15:51:21] yes [15:52:21] https://imgc.allpostersimages.com/img/print/posters/queen-mary-propeller_a-G-8007252-14258389.jpg?w=670&h=894 [15:52:53] but boat props are also a different design [15:53:19] yes, because of the way water has surface tension and the higher density [15:53:20] but you can use air propellers in water, just spin them really slow [15:53:53] would a fan be better in RC use? [15:54:12] what kind of fan [15:55:04] maybe this kind of "paddle" shape? https://www.azpartsmaster.com/Images/products/hvac/FB60719601.jpg [15:55:16] it would work for boats [15:56:08] that one is for an AC condenser unit (the kind that sit outside) [15:56:34] well, they would work but it was probably not designed for efficiency [15:57:37] http://img.weiku.com//waterpicture/2011/11/9/5/Fan_Blades_408x134_8_axial_flow_blade_plastic_axial_impeller_634658184615439307_10.jpg [15:58:11] those look like they are meant to move a large amount of air at low speed and with relatively low loading [15:58:20] hmmm true [15:58:28] the idea rc plane prop would be a one bladed one as large as it can be [15:58:51] I don't know much about boat propellers design [16:00:35] hmmm [16:01:22] just thinking that lower rpm could be beneficial, but to do that, you'd need broader blades [16:01:51] yeah [16:02:02] not broader [16:02:04] longer [16:02:13] look at glider wings vs jet fighters [16:02:26] gliders are very efficient because they have long and thin wings [16:02:37] they do a small amount of work on a large amount of air [16:03:02] while a plane the same weight with short and stubby wings would need to do a much higher amount of work on a smaller amount of air [16:03:19] https://cdn8.bigcommerce.com/s-dwlxj/images/stencil/1024x1024/products/3180/5364/windmill-hanger__38637.1518018706.PNG?c=2 [16:03:24] when you are trying to distribute a load, you want to spread it evenly accros a large area [16:03:43] that's a windmill [16:04:32] mhm [16:04:53] and modern windmills also have long thin blades [16:05:01] but it is not exactly the same [16:05:06] hmmm [16:05:09] Action: transitbiker shrugs [16:05:12] heh [16:05:19] ok lets get this livestream going [16:07:37] let's get ready to rumble [16:07:49] ya that too [16:08:16] this fight is scheduled for one fall [16:08:25] let our powers combine [16:08:28] Action: transitbiker dies in lava [16:08:39] tlove that show, haha [16:11:08] Survival SMP minecraft livestream on Empire Minecraft!
