Kerbin Circumnavigation 1.0.4/1.0.5 - Aviator Challenge Continuation

[Gahooligan]

I made an attempt to get the badge.

unfortunately i was a little over eager to get started and i spaced on taking a screenshot of the craft before flight.

Dunno if that disqualifies me. I do have everything else and i think everything is in order.

i'd hate to have to do it again, but rules are rules, indeed.

[Xannari Ferrows]

Took a crack at it.. designed the plane in a few minutes and did pretty well:

Is that a stinger? Be careful with that thing.

For some reason, that looks hard to fly. I don't know if it's because of the fact that it looks too neutrally stable or something, but I guess it worked.

It'd be weird if you were able to put this on your aircraft. I kind of want to do that now.

I know it seems extremely silly for an aircraft to not to take off from the runway, and ordinarily you would get a free pass since this is your first time, but I can't pass this because of having lost half the trip. Looks like a promising design though. That elevon in the back looks ready to cook a pizza.

[Gahooligan]

Fair enough, ill try it again.

Correctly this time.

[Gahooligan]

Hokay, Second verse, same as the first! Little bit louder and a little bit wor-actually it went much better.

Much better documentation this time around as well.

Even beat my pervious time, with better fuel consumption! Efficency +1

I hope this does it.

Can anyone tell me why the only thing that seems to heat up a lot is the Mk1 LF only tank?!

[ExaltedDuck]

hmm. thought I had a good idea. Turns out I did if one's definition of good is smoothly accelerating to mach 3 then spinning spectularly out of control and disintegrating.

revisions to the idea making the craft a little more traditional let me get up to 1700 m/s at 20000m in about 78 seconds, but from there it ran out out of steam at about 1715 m/s. And I couldn't find a way to spool up power before starting the mission clock. It would load in and start counting whether I hit ignition or not. Back to the drawing board.

Flies really well and can glide really well too. Here's the craft file:

[cikho]

tryed some improvements to the Cruiser, here is the mark4

single delta wing with double elevons on the back.. less controllable, but still nicely flying..

ready o the runway

halfway, with higher fuel consumption than before..

landed with a brand new record of 43:37 mins..

almost 2 min faster!

but i think i made some altitude mistake while flying..

target 40mins with single engine, i'm on the way!

velocity does no seem to work for me..

i've tryed to change it, but it does not work (using the old one atm)

[Xannari Ferrows]

Try them now.

[Dailey1082]

I'm hoping my signature works.. I've tried just about every option there is.

[Xannari Ferrows]

You're good now. Looks fine over here.

[zolotiyeruki]

Eight times around is a bit ridiculous. But I think I have one that will easily go 9, and might go 10. No tricks, no exploits.

With each flight, the gas mileage (proportional to (speed/thrust)) improves as the aircraft burns fuel and gets lighter. Generally, the MPG at the end of the flight is double what it is at the start. In any case, this craft is hitting an efficiency score of 104 while it has about a ton more fuel left than the 8x around craft had when it had that same efficiency. Depending on when that fuel gets burned, that's anywhere from 1 to 2 circles' worth of fuel. On the 8x run, there was enough fuel for another 1/4 circle, so....

You're already on the board.

oops.

the amount of egg on my face is immeasureable, my apologies.

I see all very small vessels. I'm wondering if it's possible to do the challenge with a Mk 3 fuselage with a big wing span and let it coast around kerbin? So far I have been unsuccessful with a design.

[Xannari Ferrows]

You should look for noname's entry. Or better yet,

Well, yes and no. I dont think i'd call my vessel small, but small seems to be the theme. As you probably already know smaller craft are easier to manuver, more aerodynamic, and cost less fuel to get to, and maintain speed.

I feel like if theres too much wing the drag would kill speed and cost fuel.

Im on the cusp of getting a circumnavigation in under an hour, and ive found it's reasonably economical to jump in and out of the air intake's usable range. like a fish jumping in and out of water. You lose a little speed but you get 3-5minute chunks of no fuel consumption -- havnt worked out of its just better to do it that way or maintain altitude where the engine is on the verge of flameout.

With a bigger craft i'd imagine getting it to speed would take a good but of fuel, and the mass of it would make manuvering a pain. But maybe not, it would be cool to see a design for a big circumnavigator vessel.

That was still an entry. I made a post here for it and everything.

Guys, I have just finished a circumnavigation in about 1:15:00. No pics since I was testing a long-range nuclear bomber with BDArmory. Since that I will retry the challenge. The plane had 1/3 fuel left, and exploded on landing because I hit the lights on the runway. Boring trip, tempted to land at the pyramids on the last leg. Highest Altitude: 29377m Cruise altitude: 25km Engine+Fuel: Wiplash + 4xMk1 jet fuel tank, fighter wings. I should be done within the day.

I did it with a subsonic B-52 replica, IIRC wierd stuff happened, but it's possible. So much fuel though - this took 23,000 units, yesterday I flew another using 26 times less fuel like 6 times as fast. You do get nice screenshots though, if you do it I recommend getting the Pilot Assistant mod and letting it fly while you just check in occasionally to check it's non-crashed and to take pictures. Otherwise that's 6 hours of your life gone.

Nice! Yes, pilot assistant is a must for the longer runs. It's amazing how little it takes to get them in the air when the fuel tanks are (almost) dry, isn't it?

Yeah, on that run I remember it starting off burning like 4 units a second and ending up going less than 1 a second. Right now I've got a light twin-wheesley plane heading west under 3x warp at 250m/s and 7600m where exactly half the mass is fuel, it'll be interesting to see how differently that flies when empty. Right now it's a brick.
