Now, I am currently testing out concepts for a reusable 1st rocket stage using FMRS, and here's my dilemma: I've tried SpaceX style, and I don't have enough for a boost-back RTLS. (I don't want to change my base expendable rocket so much that it's unrecognisable) I tried adding huge shuttle-like wings and sea floats to the booster, to land it into the ocean for a safe splashdown and recovery. But, my fuel tank kind of... I experienced a rapid unplanned disassembly, to say the least. And, also, the floats stick out so much that, if it were a real rocket, they would be sheared off during ascent. So, right now I'm toying around with ESA Adeline-style concepts, but I'm also looking for alternatives. I took a look at the ULA's Vulcan, but they don't specify on how they're going to recover it - so I would like some suggestions for other reusable 1st stage please! My solution to a similar problem was to not attach the first stage to the rear of the second stage but to the roof and floor. This way you can manage the CoM and the CoL easier. My first stages were big enough to (barely) reach orbit, so I could deorbit and land them near the KSC using parachutes (and the Trajectories mod).

KerikBalm Posted June 6, 2017 Share Posted June 6, 2017 (edited) Continued the 3x resize gameplay... got tired of how many trips my ISRU tanker was taking to refuel the shuttles for Duna and Rald: Unlike yesterday when I made a bigger ISRU craft for Mun and launched it on a disposable launcher, I decided to put my current large cargo SSTO to the limit, I hadn't actually reached the limit on payload dimensions, and launching mostly empty tanks is fine... but I figured I'd launch full tanks... surely if I could get off the ground and get supersonic, I'd end up with more fuel in orbit because of a higher fuel fraction, right? Well, just spawning on the runway was a challenge: I was almost ready to start spamming struts, or drain fuel from the payload tanks, but some tweaking of the angle that the craft spawns, some spring strength settings, and a lot of fiddling with autostrutting, and I was on my way to space: (redocked) Spoiler My fuel surplus was basically the same as when I've started with much less fuel. The added aero drag and reduced TWR ate up all the extra fuel. I could have done just as well launching with the payload tanks mostly empty. Anyway, this craft is a pure tanker, no ISRU on it. I broke up my surface base: Spoiler And just took one module that could support a kerbal (for an engineer bonus), and the miner/ ISRU, and hooked it up to my tanker: but then I decided to put the whole thing together while it refueled the tanker: My last landing of the mk3 cargo ship was the worst, its not in most of these shots because I landed it 140 meters away... I suppose I could hop it closer. I also finished setting up my com network for kerbin, and handled some other refueling operations...

XB-70A Posted June 7, 2017 Share Posted June 7, 2017 I made my WORST mistake ever today. So ridiculous and dumb that I still wonder how it could have happened... Being an off-day I decided to restart the work on my 1.2.1-made shuttle, the X-22A. I quickly saw that nothing seems problematic as I already made two test flights with her months ago. She just was a bit unstable, so in that case let's go for a new flight. But no, not a simple orbital flight, let's go to Minmus! Without any other test! () Such a beautiful umpteenth day for a flight! Samus Kerman got the honor to flew it. The climbing was pretty "normal", nothing to note apart of unpleasant tendency of being really reactive to the commands. Separation of the first stage and circularization at 200 km. At this point the spacecraft got around 2.9 km/s available. On the way to Minmus. Once again the orbital angle around the mint-ball was not pleasant for the returning trip. Return to Kerbin with still enough fuel to realize a last circularization. Even if the craft is light I was not about to risk a direct re-entry. One last maneuver and five minutes later Samus started feel the temperature rising in the cockpit... Controls were terrific at this point. After having slowed down enough with the whole surface the nose has to be lowered slowly to evade a flip but every single tap on the arrow keys immediately affect the craft comportment. It forced to control it only by making some quick and light tapping. KSC runway overshot... that's a trademark. Usually I would have re-routed to the Island airfield but as I equipped the X-22A with a "Juno" turbojet for some "powered gliding" the decision was to go back to turn back to the Space Center. The "Juno" was so helpful. Being so low in fuel was not a problem for its low consumption and the craft was so light at this time that it was able to fly instead of gliding. Then the ultimate shame happened... "Gear down and loc..." (...) "nose gear... WHERE IS THE NOSE GEAR?!!" Too low and too late to go around and find a solution. Samus HAD to land! Easy, eeeeaaasyyyyy... It probably my softest landing ever. Not using the gears brakes probably help too to make the nose touch as gently as possible. Well done Samus! I still don't understand what happened here. I still convinced that I haven't forgotten the nose gear when building it in 1.2.1... and once in the VAB it was possible to see that no gear were installed. Anyway I never felt so stupid in KSP than today at the time the landing gear lowered! Quote Link to comment Share on other sites More sharing options...

Azimech Posted June 7, 2017 Share Posted June 7, 2017 I've made a smaller hybrid helicopter based on the 77I- Azi24 Cronus, because I don't always need a stock helicopter with the length of a 747. Same engines (Asura II, 50 blowers per engine) but shorter, less wide and obviously less parts. While the Cronus is able to lift at least 65t cargo, this one might be able to haul even heavier stuff and is faster because it uses cargo bays instead of fuselage plating. We'll know for sure later, this is the first flight test. Quote Link to comment Share on other sites More sharing options...
JadeOfMaar Posted June 7, 2017 Share Posted June 7, 2017 (edited) Last night in KSP I built two SSTOs entirely from OPT parts. The first one is a somewhat replica of a streamer's all-stock SSTO freighter. I didn't go all out on cosmetics but functionally it's very similar. I even made sure it struggles paces slow and steady on ascent like a stock ship, but I forget if it's rated for payloads weighing 50 tons or 110 tons. Mine's rated for 60 tons. The second SSTO is a prototype....... Oh. There was plenty of GPP dev stuff too. Edited June 7, 2017 by JadeOfMaar Quote Link to comment Share on other sites More sharing options...
