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

boolybooly · September 12, 2012

I launched again and made a fully successfull laning (no damage) because the wheels actually hit the ground that time!
So no, the ship did not lose parts on the second landing, and on the first only becasue the Wheel parts need work.....

zekes, thanks for explaining, I know the terrain outside KSC is almost impossible to land on in v16 as I have tried and watched many craft disintegrate myself, so you have my sympathies for the first attempt and congratulations on completing the K-Prize mission successfully with your 100% reusable craft on your second. You are the right stuff! Your name is on the guest list, aka Roll of Honour, welcome to the party. (btw mechjeb is allowed by the rules see below.)

It does indeed reach an orbit of much higher than the required, I was just tired and trying to shorten the video, so I did not really think about the fact I might have cut out parts you wanted to see for factual info, and it does come to a complete stop as well, at the end of the video it is barely going 40 m/s so I think you can find that easy enough to believe. Either way I will record a new video in a day or two of it going and landing on Mun and then coming back just for ****s and giggles.

Exclipse, thanks for clarifyin. Would be interested by a MÃƒÂ¼n or Minmus mission, X-Wing looks capable. I understand tired, I get very tired and confused sometimes due to an illness I have so I can sympathise with that. And in a way because of that tiredness my dilemma remains. Obviously the apogee is much higher than required and I cannot see the parts cut from the video and I do believe whatever you tell me but when you say it reached much higher then required I am not quite sure if you understand about the rule that the PE also has to be above 70,000m as well as the AP. (Alternatively leaving Kerbin SOI and entering another also qualifies.)

I feel I should explain to make sure there is no doubt.

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.

Its just that from 11 mins onwards the velocity, altitude and elapsed time numbers in the vid of the X-Wing's orbit all correspond with a 62,000m PE, according to the elliptical orbit tab in KSP calculator! Hence my dilemma. So I am not sure if you understood the PE rule or whether you made a burn and retro burn, in the 5 mins you cut, which cancelled each other out but raised the PE briefly, or even whether you successfully landed another mission where the PE was above 70,000m. Either of the last two is a K Prize whereas the first is an unintentional gate crash ! Sorry if I seem pedantic, its just I tend to have to force myself to think clearly to counter my illness and I hate to make mistakes where other people are concerned, its almost an obsession!!

Exclipse · September 13, 2012

Haha, no I did two burns, I can post the bit with my initial PE being above 70km. I had retro'd out of my first orbit not really thinking about wanting to land near KSC, and then realized my blunder and climbed back up to orbit to get over to the KSC and then start final descent. Part of why I cut it is I felt stupid for going down and then up again... :blush:

zekes · September 13, 2012

To right all my half-right flying, I've made the Zokesia Precision Lifter 1.

I think I get the "precision pilot" award as I managed to land on the KSP runway without damage..... Awesome flyer!

This plane is my first without chutes!

EDIT: One needs to deny fuel drain from the forward tank to keep it form draining first (or the plane is tail heavy on landing) I normally use it only for retrograde burn for reentry, or emergencies..... in all an efficient flyer!

Actually later im ging to post the .craft, but only with a complete manual of how to fly it..... It is a B**CH if you didn't design it..... Tail heavy all the time if you don't know how to fix it.

djnekkid, sorry I missed out your entertaining video set to the strains of "Mario Kart 7 - Rainbow World" ! That was an intriguing workaround you used to disable the aerospike without decoupling it, well played. You did indeed complete the K Prize mission and earned the coveted advanced pilot precision award for landing at runway 27 (the other end of runway 09). While there is no prize specifically for this, the fact that you set it as your goal and did not give up until you achieved it deserves recognition and since you requested recognition for it I made a unique mention of it on the Roll of Honour aka the guest list. Thanks for posting your video and congratulations to you and your team!

Exclipse, thanks for explaining and in the light of that explanation there can be no doubt that you take your rightful place on the Roll of Honour and are a very welcome guest at the K-Prize party. Thanks again for the vid and participating in the challenge and would be interested to watch any further records of the adventures of EX0-1.

zekes, well done with your latest mission and thanks for the screenies. Since the magnificent Zokesia Precision Lifter 1 made a precise landing on the runway before taxiing off you have earned the prestigious Advanced Pilot Precision Award... yaaay! :wink:

Hmm, I seem to not be on the list...

Well, looks like it's time to build a space plane that doesn't focus on the fuel glitch!

iplop · September 13, 2012

I'll probably re-tweak this ship/post the requirements later but this is my go-to spaceplane:

boolybooly · September 14, 2012

TheHengeProphet, sorry about that, entirely forgot to add you to the list, though you were clearly awarded the K Prize above so I hope you saw that and did not think it was related to the fuel bug. I have already said more than once that the fuel bug is fair game in v16 to counter the landing issues.

Personally I am disappointed that both those bugs remain outstanding when there is a good patching system in place. IMHO current version play experience should be given a higher priority. Suffice to say I am waiting for v17 and occupying myself beta testing other games so I apologise for being a bit distracted. At the end of the day I am only human and occasionally I am slightly incompetent, which goes for us all I rather suspect!!

iplop, that's a handsome craft and a good orbit. Does it have a name and have you managed to land it in one piece?

Sorry! I really need to think about how what I type sounds. XD I did see it, but was confused why I wasn't on the list. I was planning on making a plane for this challenge that used the hacky fuel bug fix, so I didn't feel like I was cheating to get this done!

A few smileys can go a long way, when text seems so very serious.

iplop · September 15, 2012

I remade my ship to make it easier to get off the ground/control while tanks empty.

This is the new ship with the required screenshots:

(I know, not the most creative of names )

Congratulations and thanks for your K-Prize mission report iplop. These images told the story of your successful K Prize flight concisely showing an unambiguously circular 100km orbit was clearly achieved as was a safe landing, all the more remarkable for apparently being outside KSC terrain which in this version is quite a feat! You have earned your place on the roll of honour aka invitation list for the party at the Dog and Booster.

please oh please for the love of jeb could the spoilers work. With that being said i present to you the star ship noob prize. It flies it lands and finds time to bench press other planes.

EndlessWaves · September 15, 2012

Here you go:

Your spoiler worked fine, you just used it to hide a load of links, tags, rather than images, tags. On Imgur copy the BB code links rather than the direct links to the pictures.

Congratulations on completing the K Prize challenge mission razgriz86er and thanks for your screenshot record of the flight, your muscular craft made the demands of the K prize and high precision landing look easy and you are fully entitled to the kudos of an advanced pilot precision award. Well done and welcome to the Roll of Honour aka the guest list.

Archangel Lucifer, "pleased to meet you" (hope you guessed the reference) what an artful craft the White Raven is, since it does look like a large bird and appeared to fly like one, even to the point of reaching orbit around MÃƒÂ¼n which has earned you the rare accolade of a Kosmokerbal Commendation to go with your skillfully earned advanced pilot precision award, on the Roll of Honour. Well played and thanks for your mission report. Welcome to the K Prize party.

Matticus88 · September 15, 2012

Archangel Lucifer, That looks fantastic! I've never thought of using the tail part as a nose like that! i will now! Is it capable of landing on the Mun?

Archangel Lucifer · September 16, 2012

Thanks Boolybooly, its a pleasure to be inducted onto the Roll of Honour. With some better mission planning I'm sure I sure I could visit Minmus aswell but I didn't budget my fuel well enough for that on that particular run.

@Iplop - Thanks for the help but I still couldn't get it to work. Clicking on reply with quote copied your post but not the spoiler part

@Matticus88 - Thanks man, using the tail part like that had crossed my mind a few times before but I couldn't figure out a cool design for it. However it worked great on this ship. It can kind of land on the Mun but its really hard. I land it like you would a normal rocket and at the last minute use RCS to tilt the nose down but currently I have more failures than successes (damn the lack of atmposhpere :wink: ). I'm working on using seperate downwards facing rockets but this is easier said than done.

RogueMason · September 16, 2012

After hours of toying around with designs for SSTO (I'm assuming that stands for Single Stage To Orbit) spaceplanes for this challenge, I've FINALLY managed to complete it.

The design, Heavy 1 (imaginative name, I know) isn't my favourite, but it gets the job done.

Front view

Rear view

Orbital view, with a roughly 85,000km Periapsis clearly visible. The Apoapsis was around 140,000km.

Still enough fuel in the tanks to de-orbit and bring this thing down safely.

Sherrey Kerman, undoubtedly my most veteran Kerbonaut, has the honour of flying the first orbit-capable spaceplane.

A nice picture that I thought I'd take because it was... well, nice

...And it's safely down on the surface. Sure, it uses 'chutes to slow itself down, but I only deployed them once I had touchdown just to reduce speed quickly.

I managed to bring it down not terribly far from the KSC as well.

Mission statistics, for those who want to know.

I'd been wanting to test out the 'triple barrel' engine design on a spaceplane for a while, so I thought I'd use it when the previous attempt ultimately failed to get into orbit. It works well.

Just so you know, there is 1 decoupler, just behind the cockpit, but it is only used in an emergency, such as a Kraken attack.

Anyway, I hope you like it

RogueMason · September 16, 2012

Yeah, I just noticed that you can't really read the mission stats in the last picture. Oh well.

boolybooly · September 16, 2012

Looks good to me RogueMason, well done on building a bonafide Kerbal space plane and completing the K Prize mission, I know its harder than it looks. Thanks for your screenies and report. Heavy 1 does have a satisfyingly powerful C5 / Vulcan look to it and chutes are definitely allowed (is not decoupling, can be repacked!) Landing outside KSC terrain is a risky business so you have done well there too and fully deserve your place on the Roll of Honour and invitation to the K Prize party at the Dog and Booster... :wink:

Foursh · September 17, 2012

I have two submissions to this challenge.

Take-off!
Achieving orbit
Orbit achieved
SPAAAAAACE!!!
Re-entering the atmosphere
Final approach
Success! In spite of the runway's atempts to eat my plane, it survived in one piece!
Here's the flight statistics
But that's not all; with some minor modifications, it can also land on the Mun
Minmus too (much, much easier actually)
It can return easily from Minmus, but I think the Mun is a one-way trip.

It's not exactly pretty
But it makes up for it with RAW POWER!
Ascending into the heavens
Once again, orbit achieved
More space
My re-entry was a bit steep, but I needed to burn off some fuel anyways
If you leave some fuel for the turbojets, it can fly for quite a distance
In retrospect, this was a dangerously steep approach
Thankfully it's very nimble for a ship of its size (once it's used up all its fuel, that is)
And the flight stats
Unfortunately, the Delta Wing III uses up most of its fuel hauling its own bloated body though the atmosphere, so it can't really go very far past LKO. It can't even manage a munar fly-by. Still, for such a massive aircraft, it flies pretty well.

I think the Delta Wing is the new maximalist record holder

Suzaku · September 17, 2012

Wow, how much does Delta Wing weigh?

Foursh · September 17, 2012

I have no clue.

Edit: about 390 tons at launch

Edited September 17, 2012 by Foursh

Archangel Lucifer · September 17, 2012

I've been thinking - is there an award for the highest and perhaps most circular orbit with the smallest craft (by weight)? Kind of a mixture of both the altitudinalist and minimalist awards. Or perhaps one for the smallest craft to visit or land on both the mun and minmus and return safely.

Hooligan Labs · September 17, 2012

Here is my submittal for the K-Prize, a single stage spaceplane that goes to the Mun and Minimus without any mods!
