Thread: The K Prize - 100% reusable spaceplane to orbit and back

  1. #1

    The K Prize - 100% reusable spaceplane to orbit and back

    The K-Prize Party Thread.


    K-Prize badge by WafflesToo (sig badges).


    The K Prize challenge is to make the obvious craft, a spaceplane, and make it work. All those who succeed will be included on the roll of honour and get a free back stage pass to hang with Kay Kool and the Kerbettes after their next live performance at the Dog and Booster (where free beer will be available).

    Rules
    1. The craft may not lose any parts in flight, no decoupling allowed.
    2. The craft must lift off horizontally, reach orbit (PE > 70,000m) and land intact ready for 'refuelling'.
    3. All fuel tanks, wings (lift generators) and engine parts must be stock, for fairness.

    Provisos to rule 1.
    A. Payloads may decouple from the craft providing all payload tanks are as full on decoupling as at launch and any thrust (or lift) generators on the payload were not used prior to decoupling.
    B. Docking is permitted providing no fuel is transferred (net per fuel type) into the K-Prize craft (it can be transferred out). Crew transfers are permitted.


    Kudos
    1. Smallest ship (by weight). Minimalist record.
    2. Largest ship (by weight). Maximalist record.
    3. Highest orbit. Altitudinalist record.
    4. Landing on KSC terrain. Pilot proficiency medal.
    5. Landing on any KSC runway or docking in orbit. Advanced pilot precision award (1stClass for both).
    6. Visiting other SOIs. Kosmokerbal Commendation.
    7. Planetoid landings. Astrokerbal Distinction.
    8. Payload to orbit. Utilitarial Commendation.
    9. Payload to planet surface. Utilitarial Distinction.
    Prefixes: Exploratory applies to planetoid missions and Expeditionary applies to planetary lander missions outside Kerbin's sphere of influence. (Planets are defined as the central body in their own SOI within Kerbols SOI or gravity exceeding 0.75 of Kerbins.)

    Re: The K Prize - 100% reusable spaceplane to orbit and back

    Craft files would be nice by the end of this challenge. Making space planes is hard! making SSTO space plane is extra hard.
    Can\'t wait to see what people come up with...

    One question. Vertical launches are perfectly ok right?

    Re: The K Prize - 100% reusable spaceplane to orbit and back

    Woot! I have an SSTO spaceplane in orbit at 230km, I\'ll land at the KSC and upload the pics, watch this post!

    Update: Aircraft failed to return to Kerbin, the weight distribution was such that the engine flew through the airframe and the craft disintegrated, I have another more stable plane but I need to get out in this sun, it\'s been cold for so long here.

    Can't wait to see what people come up with...

    One question. Vertical launches are perfectly ok right?
    I welcome your enthusiasm hebdomad. Did you see rule #2?

    Rule #2, the launch has to be horizontal by which I mean has to happen on the runway and begin with horizontal movement, after which you can fly it any way you want. 8)

    Damn... well there goes my one and only SSTO that might have parts 'accidently' fall off...

    Made this over the weekend,

    The Wespe:

    Gets to at least 70km, all one piece, 2 stages, enough RCS fuel for orbital maneuvering, and enough jet fuel to do a controlled landing. All 0.15 vanilla parts.

    Looks like my glorified rocket approach is... iffy.

    It needs the drop at the end of the runway to get airborne, is barely capable of a 70 km orbit, and has a L/D of ~2 with empty tanks and below ~2 km altitude. It cannot safely ditch on water. Land capability is currently unknown. =/

The interesting answer is that it's a social experiment to see how people react to something that is harder, but that they think is easier.

    When the rocket fuel tanks finally get separated from jet fuel ones (0.16 i think), I\'m sure this challenge would be much more challenging. The Rocket fuel tanks simply carry so much more for their weight.

    Heh, looks like I need to step up my spaceplane game. The one spaceplane I\'ve gotten into orbit ran out of fuel doing so, partially due to mis-routed fuel lines, and ditched a pair of lower-atmosphere engines, an SRB, and the landing gear (attached to the engines and SRB) on the way up. (The pod decouples and lands via parachute. I\'m not that mean.)

    First, though, I need to build something that can rendezvous with my stranded spaceplane and nudge it back into the atmosphere.

    You have no idea how much I have tried to do that. Try and try, space is huge. I still haven\'t had a plane or ship that can do that.

    Tested your design out, I really like it Worked fantastically, got a stable 150km orbit, and brought it back down on the pad
