    Here's another craft operating on mostly the same design I had before, but stripped down as much as possible. Inflatable airlocks aren't the most comfy, especially when they're deflated with Jeb inside them, but they are really good for fuel efficiency. In VAB. 1.3 units of fuel remaining, just above the turboshaft entry, with potential to go down even further. 722 kg mass - this won't win any mass efficiency awards but I'm not going for that. Airlock is extended on runway Jeb gets out of a conveniently placed rover and then the airlock is retracted with him in it, so it can fit in the fairing. Kerbals must be very flexible Lower weight means less wing area, and thus less drag + thrust at a faster cruise speed - great for efficiency Engine cut with 0.24 fuel remaining - 1.06 fuel actually used (equal to my command chair entry!), and it's possible that it might be pushed below 1 fuel Parachute isn't the most efficient option but it's certainly the easiest Landed

    After some ill fated design changes, I managed to get Jeb to the island airfield on just 1700 mL of fuel. 1184 kg start mass, 1.7 liters of fuel - score is 0.0014 Boost to 110 m/s - this is the point where I can maintain level flight at a -1 degree pitch, which minimizes drag and thus minimizes thrust needed. I keep the throttle at about 5-6% for the rest of the fllight Engine flames out at this point so I point horizontal to maximize lift to drag ratio and thus glide distance I'm barely able to glide to the airfield at which point I deploy the parachute just like normal. However I come in a lot lower this time because of the reduced fuel Landed and no parts broken Without a pretty major design change, I probably won't be able to improve at all on this design. However I am thinking of some potential changes to this craft. Mainly I want to reduce mass as much as possible. This will reduce the amount of fuel I use for takeoff and for the initial boost, as well as reducing wing area which will cut drag. I can't really think of any other way to improve this. The benefit of this mass reduction is apparent in the command chair craft that I mistakenly tried to enter - it used significantly less fuel than this craft even though it had a much less optimized flight profile

    Ok, here's a quick new submission. I added more basic fins and reduced the initial fuel load to 2.1 units, but left the craft otherwise unchanged. (This is to leave room for later improvement) In VAB. 2.1 units of fuel, 1188 kg - score of 0.0017 Boost is done, throttling way down to cruise at about Mach 0.5 for the rest of the way. You can see that most of the fuel is used here Cruising further - I might have been able to cut the engine here actually, but I wanted to be sure of making it to the airfield. I definitely could have launched with 1.9 units of fuel however Engine cut - I have a lot more energy than I need here Parachute deployed Landed

    Coffee can planes just won't be as efficient as a Goliath powered plane, because the Goliath is larger but has higher specific impulse. The ideal plane for fuel/mass would probably be something like: Single Goliath powered, engine is occluded and a shock cone is used for drag purposes instead As many fairing occluded parts as possible to reduce drag Big wings While the ideal plane for raw fuel consumption would probably be something similar to my earlier design but with bigger wings and a better flight profile.

    Atmospheric EVA isn't allowed - no paragliding

    They were talking about engine overclocking using KAL, which is a glitch but not a cheat

    Ok, new submission with command pod: In VAB, mass 1117 kg On runway, 5.4 units of fuel loaded Boost ended Boost was just short of the airfield so I did a second boost. Probably not the most efficient way to go Fairing and parachute deployed Landed with 3.04 units of fuel left, 2.36 units of fuel used, and no parts broken. I think some possible improvements would be: -Instead of a boost to Mach 1, cruise for a bit at a lower speed and have a bit more wing area to reduce energy lost to drag - maybe? -Figure out how to boost for less fuel - better takeoff profile, etc However, if this challenge were to be repurposed for a longer run, then the optimal flight profile would change significantly. Maybe have Dessert Airfield / Baikerbanur (for non-DLC friendly) as well as Island Airfield destinations

    @ralanboyle Here's a submission without a turboshaft. It uses a Juno engine and a drag occluded fairing. The general flight profile is to get to just under Mach 1 to avoid any transonic drag losses then cut the engine and cruise the rest of the way to the island airfield. I didn't get the timing quite right - you'll see I had quite a bit of speed excess at the airfield, meaning I boosted too long. Craft in VAB. It weighs 639 kg and has 3.6 units of liquid fuel. On runway, with 3.6 units of fuel loaded Boosting up to just under Mach 1 Engine cut - glides the rest of the way to the airfield Pulling up to maintain speed Detaching the fairing, deploying chute Landed - 1.06 units of fuel used Edit - I completely missed the requirement that there are no command seats allowed. Guess I'll redo this with a command pod
  9. camacju
    Are turboshafts allowed?
  10. camacju
    I used bettertimewarp so I assume it's allowed. I can't find any reason why it wouldn't be

    I haven't had much time to do this challenge but here's me getting my submission into orbit. It consists of an oversized fuel tanker and a tiny probe. In VAB. 125 parts, well under height limit, two layers of boosters, one with eight boosters and one with six more Launch Boosters detached Sustainer detached Circularizing In orbit. Tanker has 3800 m/s left and probe has a bunch of delta-v also, I can do a ton of flybys with this much fuel
  12. camacju
    Sorry if I wasn't clear - I used orbital mechanics to gain more velocity than a run-up was able to give.
  13. camacju
    My waverider was a 15 ton nuclear rocket launched from 19 km. From there it went to orbit and did all the other things. I don't need to add it to ballistic class. To acknowledge speed I didn't use the F3 menu because it's pretty inaccurate, I used the navball instead.
  14. camacju
    Actually, leaving the SOI of Kerbin might be the best way to gain large amounts of speed for comparatively little delta-v. You'd need maybe 2000 m/s in low Kerbin orbit. -Use Mun assists for an Eve transfer -Eve and Kerbin assists to Jool -Jool assist brings your orbit high above Kerbol -At apoapsis reverse your orbit and bring periapsis to Kerbin -At periapsis adjust your orbital period for a Kerbin encounter Now you have >20 km/s of relative velocity. That's what I did for the waverider category

    Stacked service bays make everything inside them completely immune to reentry heating
  16. camacju
    I had a feeling hovering would be the ideal way to go here. I think the only way to beat that score would be to reduce dry mass as much as possible
  17. camacju
    I might try an unmanned mission, I feel like they'll be competitive
  18. camacju
    Judging from the F3 screen you boosted to a super high speed and exploded at 43 km due to overheating. Not sure how much that accomplishes the challenge
  19. camacju
    I feel like parachutes would be a pretty good option for high drag. Either that or empty sepratrons
  20. camacju
    Probably the best (worst?) way to do this will be to have a jet engine angled almost all the way down and as heavy of a craft as possible. Then go full throttle, inch down the runway until your wings provide that extra tiny bit of lift, and float eastward to the island airfield.
  21. camacju
    Yeah, I would not be able to do a weeks-long mission I think my longest ever mission (my grand tour) took three days and I was pretty burnt out by the end of it. I prefer short and modestly optimized missions with efficient flying which might seem repetitive to some people however
  22. camacju
    Bradley Whistance's discord has something like this. Level 1 Fly a SSTO and land it back at Kerbin Level 2 Land a SSTO on top of the VAB Helipad Get to 1 km/s on the surface of Kerbin Level 3 Get a Kerbal to the surface of Eve and back to Kerbin Level 4 Land the Jool 5 Level 5 Go to Laythe and back on a single stage, no ISRU Level 6 [nothing listed officially] Level 7 Get from the surface of Eve to orbit on a single stage By this scale I'm probably level 6 since Laythe SSTO is very doable for me and I've done SSTO missions to Laythe + other places. I might try for level 7 but idk if I have the time

    I feel like this should go in the Spacecraft Exchange or be a mission report
  24. camacju
    KAL overclocking is a cheat in my opinion, as it's not available to all KSP players and is definitely not intended behavior
  25. camacju
    The plane as-is should easily be able to get up to 1400-1500 m/s. Are you accelerating to Mach 1 at sea level or at altitude?
