I'll edit my first post for this. darnit... knowing that you made a vessel 4 times less heavy than mine, makes me want to redo the challenge! haha! thanks for the idea dude! I'm loving this challenge! -
After a week of designing and testing I finally came up with a working version for this challenge, where I have to design a Heli STTO that's able to get to Duna and back! I made a Single Stage to Duna vessel with ISRU capabilities. HHere are its specs: - Weight: 127 tonnes (wet) / 37 tonnes (dry) - Delta v budget: 4900 m/s - Rocket engines: 2 vectors, 1 nuke - Helicopter: 2 large shift-able motors with 8 propellers each. It was an awesome challenge, but I did come to a conclusion that MY Heli-SSTD ships are very impractical and bulky. It is soooo much easier just doing a multiple stage to duna design. But that wouldn’t be a challenge, now would it! I made a small video of the mission. I hope you guys like it!

epic! I can't wait to see your design! My expierence with ducted fans is that they work perfectly on kerbin, but not so much on Duna. Guess I was wrong!

I'm trying to build a chopper and I'm balancing out the centre of mass into the centre of lift. however, the centre of lift is wrongly shown on the ground. is there a way to get it on the proper location again? this current chopper is able to fly btw. https://imgur.com/0sZeG1Y https://imgur.com/0sZeG1Y

I only encounter blade stretching when I timewarp 2x...4x. so I can't help you out. holy moly that's impressive! this is enough motivation te keep me going!

Very interesting idea. I haven't succeeded in making a prop plane fly on duna though. There is so little atmospheric pressure to play with that wings just make things heavy without providing enough lift/speed. I did make a helicopter once but that thing was stripped to its core haha. Adding fuel to that would make the craft too heavy to lift.. I think... I'm hoping other people are having better luck at finishing this challenge. I'm constantly reminded why I dont like to build ssto's: they rapidly get so damn bulky and difficult to handle. XD I wont stop trying though My first planes didn't use the kal1000 units either. The rotors had fixed angles and the motor was either on or off... this works perfectly for planes. Helicopters are a whole different subject though
-
awesome ship and pictures! thanks for sharing
-
I don't think you'll save that much delta v. did you actually get to an altitude of 20km in a prop vessel? I'm not getting anything higher than 14 km. 2 days ago I launched a ship from a floating platform at 10km and found that i almost had to use 3100 m/s to get into orbit. I do have to confess that the ascend profile wasn't very optimal though.
-
Thanks eveybody. it makes sense now! i also tested it, just for chips and giggles and found the wrong assumption i made. thanks for contributing.
-
haha ah, so that assumption is where i "fornicated up" XD...
-
the thing i just can't wrap my head around is that if i go straight up I should somehow see the satalite coming closer and closer, right? because, when I go down again, I land back at the same place I started, am I right? so during this whole flight, I would be able to "see" the satelite in front of me? but when I get really close to the ship, what will happen then? my peripasis is way different so there must be a huge velocity difference somehow... argh... i want to test this!!!
-
So I had this shower thought… if you have a satellite in geosynchronous orbit… and you’re standing straight under its position on the ground… What would happen if you fly straight up in a rocket towards the position of the satellite (so pitch @ 90 degrees)? Would you encounter the vessel? The relative velocities wouldn’t match, right? Since there is a difference in horizontal velocity… does anybody know?
-
yeah, i've been toying around with helicopter SSTO vessels for several evenings now and man what do those things tend to get bulky fast! My first design was meant for a trip from Kerbin to Duna, but getting a heavy craft off the ground on Duna is nearly impossible with the thin atmosphere. Jool is probably a bit more easy, but it needs quite a lot of delta v and there's hardly anything useful reasons for going there. Thanks mister! it took me quite some time to design a ship that could transport everything over there. It was a great challenge!
-
YO DAWG, I heard you like spaceplanes, so we build a spacaplace that carries spaceplanes! epic design dude! RIP your CPU haha
-
Lifting vessels of the ground is soooo 2019! With the airspace platform, you're able to launch vessels into space with only vacuum engines! it saves like... uhm.. at least.. 100 m/s delta v? Or something hehe. ok.. so it's not that efficient, but hey..it looks cool... right?

Sorry for being off topic, but I got into an Joolian orbit with approximately ~5500-6000 m/s delta v after visiting my holiday home near the surface of Jool. I noticed that the drag in the upper Joolian atmosphere is much lower compared to the drag on Eve's upper atmosphere. because of Jool's low gravitational force, I think it's easier to reach orbit from Jool than from Eve. But you do need more delta v to get there... hmm.. I'll stop rambling now... On topic: This challenge looks awesome and I will give it a go when I've got the time.
-
wow, that's a nice compact build you've got there! thanks for sharing.
-
I circumnavigated Eve with a lightweight chopper and brought my Kerbal safely back home afterwards using a Helicopter-Rocket hybrid. The idea was to make the chopper small and fast. I ended up with a compact design that flies very stable. Here are its specs: The circumnavigation took around 7 hours to complete, which is a record for me (hurray). I made a small video of the mission.

thanks for the comment @AHHans. This would work on Jool as well. In this particular case I was building a floating "village" (2 cottages and a ascend vehicle to get back in orbit). reloading would mean I would have to get all 3 rotor up and running again and fine tune every velocity so that the cottages and ascend vehicle would be aligned next to each other.. every times. that is not what I had in mind haha. It's a shame KSP doesn't work like that but there are probably many reasons why this feature wasn't included in the game.
-
Well.. I've noticed the same issue when I was circumnavigating Kerban in a helicopter. It didn't happen every time, but I've experienced situations where I missed a crucial quicksaves due to this "bug" and i had to redo hours of work.
-
Why does it take so long to realize you forgot something?

did you pull a "the martian" on a kerbal? how did you find this 2 year old post btw? necroing is apparently frowned upon. -
I recently did a mission near the "surface" of Jool with a couple of floating helicopters. It worked perfectly, but I had to do everything in one go, because after reloading a savegame, the rotors of the floating vessels would stop rotating and plumut to the ground ...uh..I mean abyss. Is there a way to keep the rotors spinning, maintaining their angle of attack and lift?
