Yeah, the Y-Axis offset is a huge problem, also on an american style shuttle (probably still smaller than on a buran): On the bright side: A heavy payload will reduce the offset (this one is empty)^^ TCA looks promising but also pretty complicated on the first sight. Unfortunately, the thread doesn't seems to be supported very well, maybe some other shuttle pilots got some experience with the mod and can explain it a bit. By the way, there is another nuance about Energia which is not that obvious from the first look, but improves the handling greatly - second stage engines are not under center of the stage. They are closer to the payload/orbiter - which greatly reduces necessary engine deflection in final parts of the ascent (and for the early part boosters are meant to fix the balance by being on the other side of CoM) Link to comment Share on other sites More sharing options...
sturmhauke Posted December 17, 2018 Share Posted December 17, 2018 I tinkered with my old launch vehicle a bit more (I call it "Phoenix"), using some of you guys' suggestions, but I got impatient with it. I might go back at some point and try again. Meanwhile, I completed my less realistic but more Kerbally symmetrical launch system, called "Firetail", and used it to do the STS-3 mission.

michal.don Posted December 18, 2018 Author Share Posted December 18, 2018 Sorry for the slight delay again, full christmas-madness is starting to take more and more of my time.... Interesting debate about the CoM shifts and possible CoT adjustments - that's one of the things I love about this thread.... Anyway, let's check the entries: On 12/14/2018 at 1:28 AM, 4x4cheesecake said: So there is no new flight report in almost 2 weeks? Let's change that and fire up the engines again! STS - 5T Great execution of the free return maneuver - and without correction burns, good job! And great improvised change of landing site, that's a feat worthy of a great test pilot And, I don't know why, but I absolutely love the screenshot of the shuttle changing the inclination in the atmosphere - that's a great picture! On 12/16/2018 at 10:09 AM, 4x4cheesecake said: Let's hope everything is fine with STS - 5T because here is already: STS - 6T I was looking forward to seeing creative solutions of this one - and I'm certainly not disappointed - recovery via a giant bathtub Not the most elegant craft around, but gets the job done for sure. So, good job on both of your missions, and congratulations on being the first one to claim the new badge! Michal.don Link to comment Share on other sites More sharing options...

So, good job on both of your missions, and congratulations on being the first one to claim the new badge! Glad to hear you like my solution The first prototype of the craft actually got a full 'cup' on top of it: But I had to get rid of ~3/4 of the tube to lower the part count and especially the mass...there is also still another variation of the craft in development, basically the same craft but with wings...just for fun Oh and: WOOHOOO FIRST!! Apropos in development: I'm also working on a third shuttle to close the gab between the small, LKO capable one and the huge 'I can reache every planet' one I plan to use it in the Eve mission (the other shuttles cannot reach Eve or are not able to aerobreak into an orbit in one shot), really curious how it will perform but still needs some more finetuning regarding the balacing, which actually brought me back to the CoM shift issue^^ Spoiler It got a boxwing!

Thanks! I even had someone on imgur request the craft file, so I put it up on my KerbalX page. Now I'm thinking of some kind of shenanigans to justify the rescue mission. Oh, the rescue shuttle doesn't have to be the same design as the damaged shuttle, does it? I have an older Dreamchaser-style design specifically meant for rescues.

michal.don Posted December 22, 2018 Author Share Posted December 22, 2018 My fellow shuttle-holics, there is a special Christmas mission available for the duration of the holidays. You will be catching lost christmas presents in space and delivering them to the North pole (the full description is in the OP) There is also a special badge for anyone who completes this mission I hope you will have fun with this short mission, and I wish you all very happy holidays, hopefully spent with the people who you care for and who really matter in your life. All the best to all of you, lots of luck and happiness in the new year, And I'm looking forward to seeing each and every one of you around here and the rest of the forums.

I just startet to work on the Eve-STS 1 so I can hand it in tomorrow, because of 'christmas eve'...you know...yeah...bad joke xD But this is much better^^ I love the idea and the presents...the bow looks better than every real bow made by me Do you have a shuttle on your christmas tree for real? I guess some people wouldn't be pleased if I try that but it looks cool ^^ edit: The present got 117 parts?!

4x4cheesecake Posted December 22, 2018 Share Posted December 22, 2018 Phew, that's a huge mission if you decide to pick up all three presents But here we go: STS - 1C (really mad paint skills here^^) Well, not much to say about it....it is a really cool mission and more challenging than it looks like on the first moment. On the other hand, I didn't plan much for this mission, I bascially just put 3 docking ports into the orbiter and launched the shuttle, hoping for the best Spoiler Lift-off!: First destination: Duna Some basic aerobreaking: Capture the first present: Head back to Kerbin: Keep cool during a hot aerobreak: Second destination: Mun! Got a really nice shot while performing the rendevouz maneuver: Capture the second present: Third destination: Minmus! Always on the dark side One port is still available: Got it! Back at Kerbin: We should do more stuff around the poles, it looks really cool! Landed: Really close to the pole: So...where's Santa? Full album: https://imgur.com/a/KvtiwJS (picture heavy!)

sturmhauke Posted December 22, 2018 Share Posted December 22, 2018 You have a lot of dV on that thing, geez. I'd need to add some drop tanks to mine, or use a different shuttle. Link to comment Share on other sites More sharing options...
Starslinger999 Posted December 22, 2018 Share Posted December 22, 2018 (edited) Had to update my new shuttle because 1.6 dropped right after I finished. Using 3.75m Boosters now and no weird ET up front for now. Can fly an Orange tank to orbit and has nuclear engines for interplanetary missions. Will get pictures here ASAP *Edit* Pics: https://imgur.com/gallery/KSl7xyV It should be ok with the 40t payload as the fuel station was about 38.57t Edited December 23, 2018 by Starslinger999 Link to comment Share on other sites More sharing options...

Alchemist Posted December 23, 2018 Share Posted December 23, 2018 (edited) Payload recovery? Mun, Minmus and Duna? Well, let me just check where I put the latest version of HRO-M... Now need to plot the transfer to the third one ----- And here it goes Wait, why do the OMS perform worse than usual? They got nerfed!? Oh well, we still got the delta v to get everywhere we need. ---- Bob, do you know who calibrated the Kerbnet biome detection? And are you sure those are the correct coordinates? And somebody please remind Santa Kerman that picking deliveries from Duna takes around 3 years with normal means of transportation unlike whatever he uses. Full report will be... when it's finished (hopefully, tomorrow) ___ Oh, and 1 more thing: if somebody doesn't want to do all the setting it up stuff, here is the save file with the presents in the requested orbits Edited December 23, 2018 by Alchemist Link to comment Share on other sites More sharing options...

Starslinger999 Posted December 24, 2018 Share Posted December 24, 2018 (edited) @michal.don I'm having a bit of trouble with my STS 2a Mission. I accidentally removed 2 SAS wheels when I Refitted my shuttle and now it's unstable in atmosphere (I had to aerobrake to a lower orbit and it took a few quicksaves because it kept flipping out) but I do have a station in orbit with 2 drones with the large SAS wheels. Will it still be ok If I rendezvous with it and take a drone down for a landing? Edited December 24, 2018 by Starslinger999 Link to comment Share on other sites More sharing options...

I think this might be a problem...transfer of fuel from already existing vessels like stations isn't allowed either and I think the same accounts for parts. Also, payload design is part of the challenge, so you may have to prove that payload + reaction wheels still fit into the cargo bay. On the other hand, an additional rendevouz and docking maneuver will increase the difficulty and fuel requirements for the mission, so maybe there will be an exception for you Try shifting the CoM like suggest by Kerbolitto seem to be the better solution Edited December 24, 2018 by 4x4cheesecake Link to comment Share on other sites More sharing options...
chargan Posted December 24, 2018 Share Posted December 24, 2018 https://redd.it/9rkpdj I think this only qualifies for STS-1a but here's a pair of shuttles with reusable boosters I used to get to Duna and back. Link to comment Share on other sites More sharing options...

Will it still be ok If I rendezvous with it and take a drone down for a landing? Actually, that would be no-go. I have to draw a line somewhere, and while it would not be such a big issue in this mission, it's not possible to utilise infrastructure not built by the shuttle program. If I let this go, some people would launch all kinds of stuff to help them in their missions. So, try the fuel-balancing trick to land your shuttle - it might work. You don't need a lot of reaction wheels to land from LKO, if your design is aerodynamicaly decent I'm sorry and I hope you understand my reasons, Michal.don Link to comment Share on other sites More sharing options...
