  1. Need help with stock propeller

    If you keep going for electric propellers... Here's my design on propeller SSTO on kerbin. It uses Aerospike + Nerva combination. I think ions are too weak to get this work, as the drag is too much. Also, I found later that mixing engine resulted in worse performance. So I recommend choose one best engine to use. Also this thread helps greatly with propeller design: Besides, I observed that the drag of the total plane matches with the lift generated from the propellers..
  2. Need help with stock propeller

    Now this is what I was thinking about years. I decided to forget about it, due to the weakness of propellers. Electric propellers are very weak on its TWR side. I had hard time getting it over 2 on operation. And - Eve has higher gravity, which makes this weakness worse. So 8km on kerbin won't guarantee good high altitude performance on eve. I got a prop plane to 10km with 1g, but it refused to go over 5km with 1.7g. I recommend rocket-turboprop. It can gain both higher TWR and higher effective ISP in atmosphere, so why not try it? Well, and yeah I agree that it's an exploit, but at least for me it is so fun to make!
  3. Worked on turboprops, got these with great fun! Thanks, especially to @Majorjim! (and @klond ) for the RCS-Thermometer hinges! http://imgur.com/a/wsL4O Since I'm too into the performance of these engines to resist putting all the effort on optimizing the engine, I tried to maximize its TWR output. Here's TWR 7~8 in action. (Looks a bit wierd) Here are 8 juno engines lifting 35t. Engine section weighs 4.73t excluding the mk3 cargo bay. Think I can say tgat the effective ISP is 14000. Currently fabricating something actually useful out of this engine. Not going to be completed soon for no time is allowed for me to work with this simulator.
  4. Because I want to kill Kerbals with a reason. More specifically: By reward I mean special resources/parts/conditions from the kerbal or the kraken. Or something that is not reputation/fund - because these does not make sense. Moreover, I think there should be corresponding penalty on this. But I don't care about this point too much. Are there any?
  5. Is it practical to aerobrake with airbrakes on Duna? I'm planning for fully fledged Duna mission involving tankers. I was a bit worried as I heard that Duna's atmosphere is too thin for a heavy craft to shave off reasonable amount of speed. As its atmosphere is mild as to heating, would it be possible to use airbreaks? Or wouldn't it be needed? (Or, should I use inflatable headshields?)
  6. Impact Confirmed Challenge

    Hmm... Fairings?
  7. SRB and Eve

    Well, I should've elaborated this: SRBs are not useful if the goal is not about money. (i.e. I meant 'if only' with the word 'only') No need to use it for either simplicity, aesthetics or mass. On the other hand, now I realized there is one more case for SRBs: when you challenged yourself to create eve ascent vehicle out of SRBs.
  8. SRB and Eve

    I'm quite sure that SRBs will only worth it for the money. They are pretty cheap to dispose of, but have no good Isp. (which is especially critical on Eve)
  9. As far as I know, SQUAD added support for pretty much every language so that language packs can easily be incorporated(by individual user) - Take a look at fonts. It's just that the stock install contains 5 languages, which I think is to boost up the sale by supporting the languages with large(st-ish) potential playerbase.
  10. You mean this? Couldn't resist... Well you were partly right. What I want is some kind of space-altar which can be activated in specific positions/orbits. You can gain special resources/parts to gain some engine/ISRU/whatever. If there is nothing for this, I woyld seriously consider making a mod. Before that: how much work would be needed for this kind of mod?
  11. Proper Re-entry question

    You don't need ablators in heatshields during reentry from LKO-scale speed - adjacent parts might be subjected to more heat, but I don't think it will ruin your ship as the part there is the cargo bay. Imo direct reentry is sometimes not feasible, and it could be better to bounce off and enter again in kerbal universe.
  12. This one is simple challenge of flying VTOL as long as you can, without landing or crashing it. Rules: 1. No cheating, no debug menu, no physics exploits. Electric engines are allowed and counted as honorable entry. 2. There will be a main mission and several missions to show capability of your craft. Any landing or takeoff in any mission should be vertical. 3. The scoring will be based on the mission time from the main mission. Your craft should maintain altitude under 5km overall, and you should not touch any ground in the meantime. * Mission time is the time from the craft takes off to land. 4. Your craft should be able to land on VAB, and take off again. (Proof needed - these capabilities can be done on the separate mission) 5. Your craft should be able to reach the island runway. (Proof needed) 6. Do not stage. Disposal of any part is prohibited. 6. Air-to-air refueling is allowed, provided you can. Refueling time is subtracted from total mission time. All other types of refueling is prohibited. 7. If your craft is stable and maintains altitude well, then you can add (Remaining Fuel)/(Fuel Consumption Rate) to the mission time and recover the craft. Score: Base score is the mission time you flied the VTOL during the main mission There are multipliers based on capability of your craft. Proof needed, can be done on a separate mission. X1.1 (multiply) if the craft can land on SPH. X1.1 if the craft can fly under R&D bridge. X1.2 if engine section of the craft is either ducted or secured in cargo bay. X1.2 if the craft can land on R&D bridge. X1.5 if the craft can reach orbit. X1.6 if the craft can circumnavigate under 5km of altitude. X3 if the craft can land on Duna intact. X4 if the craft can land on Laythe intact. X1000 if the craft can get to and land on Laythe and back. (Don't panic, the multiplier will be x5 once this is proven to be possible) X10000 if the craft can get to and land on Tylo and back. - This alone is a challenge, isn't it? Leaderboards: 1. 65,405 seconds, @sevenperforce , with great tiltplane VTOL SSTO capable of Duna! Judging from the pictures it also seems to have great manueverability, which is hard for a SSTO(especially long-range one). 2.
  13. What did you do in KSP today?

    Made a compact mk3 SSTO. Maybe this could be useful for my career save. Realized that now LF-only SSTO is easy to make, and stock jet engines are, indeed, overpowered compared either to reality or to stock rocket engines.
  14. SSTOs! Post your pictures here~

    Wanted to create a "small" mk3 spaceplane with decent crew capacity, without any oxidizer. A few adjustments would make this plane great for passenger delivery to LKO in career.
  15. What did you do in KSP today?

    Designing new model of a broadcast hoverdrone. This hovercraft features longer table and more reporters/casters. If flies! Not so well, and needs to be gentle and careful, but it flies anyway. Here we landed! Now you can broadcast something on the R&D bridge! So what to introduce, that is the question...
  16. VTOL longevity challenge

    @sevenperforce, that's splendid! Thanks for sharing your great plane & entry. I didn't seriously thought that long-range VTOL SSTO is actually a thing, with tilting the whole plane. Great job you've done there. Also passing under the R&D bridge SSTO... I just want to give one more karma for this! By the way, I'm trying my own hovercraft on this challenge. Hopefully this will show how a non-plane VTOL could be more efficient on flight..
  17. It's definitely be possible with a heatshield, and more practical with parts with heat tolerance over 2000K -without heatshield this time. Shallow reentry is forgiving for the latter case. Also mk3 spaceplane can be excellent for recovery of small parts, as it can get to orbit for nearly nothing and grants 100% recovery. But even with rockets, lifting 350/t is possible. As the hulk will cost more than 300 and recovery equipment don't cost much, there should be net gain in funds if you aim it right. The real question is: Is it worth the real time spent for the mission?
  18. VTOL longevity challenge

    Oooh.. Actually the part was a joke for the debunked VTOL SSTO video.(Thus strikeout) I thought additional vtol engine would be too much dry mass preventing the Laythe capability. Also there's drag issues. For the craft in the picture, over 320kN of upward thrust is needed. It means over 3 thuds or 2 darts are needed. But now I see that the Nerv could make it possible. So, I'm going to adjust the multiplier to x5 when it's done. Great point. I'll change it so that circumnavigation run is separate from the main mission, since it's more about capabilities. Then the lower speed one will count.
  19. How to get friends addicted to ksp?

    Just don't try, it won't work unless they are special. I've seen that KSP is generally not considered as a game for majority of game players, since this 'game' lacks concrete goals and requires fair amount of knowledge. This alone rules out majority of players from playing KSP, as it's usually headache to create their own goal even in usual circumstances. Moreover, it's hard to be interesting without great interest on space exploration, as there are next to no attractions other than spacey-things and so-called kerbal-ism. Which means most players won't try to get into this game and just fed up with - face it - boring and low-quality explosions. I guess you would be asked 'is this a game, or a simulator?'. For them it is too much of realism, so they will just think it's a realistic simulator to mess up with. You need to accept that it's just a boring simulator for quite a bit of players. But. This game could be fatal for your science teachers/teaching assistants. (Don't know about professors. Maybe I have to try it later)
  20. VTOL longevity challenge

    Yes, it's fine.
  21. VTOL longevity challenge

    Hm, I didn't thought about this. Because.. you need to be capable of VAB landing. This is interesting, Please let me know if you manage to do it!
  22. VTOL longevity challenge

    @The_Rocketeer parasails are fine, given that they take off vertically.
  23. VTOL longevity challenge

    Good catch! 1. You can do as many attempts as you want to satisfy the conditions - as there are no restrictions with it -, except for the circumnavigation one. The circumnavigation should be done during the main timed mission. 2. No, you just need to show that your craft has the capabilities. No need to do it during the same mission. 3. Yes you can adjust the fuel load. As I've got used to those electric engines, I made these rules with them in my mind. Good luck maintaining altitude with electric engines! It will count as honored entry. (Out of scoring system)
  24. VTOL longevity challenge

    Only circumnavigation should be done during the mission(timed run). Other than that, separate mission is fine. (And recommended as well)
  25. What did you do in KSP today?

    Not today, but here's screenshots of swingbys on Jool system. Laythe capture is not only practical, but also allows voyage to other moons in relatively shorter period. Why Tylo? Just more pics: (Immersive on personal appetite - edit: kerbal system in a nutshell?) Besides, spinning top seems to be a thing in ksp. This thing refused to stop spinning until I accidentally timewarped. This thing needs to be shaped.
