Kerbin Circumnavigation 1.0.4/1.0.5 - Aviator Challenge Continuation

[nicky4096]

wow! I went through all 141 pictures... it was exciting

i think you have completed the first circumnavigation with basics so far!

[Xannari Ferrows]

So, I decided to have a go at this challenge last night, but decided I wanted to try it with basic jet engines and not have to worry about the heat. Naturally, a speed record is already out of the question for me. The attempt is below:

Basics? I'd make a programming school pun, but it's a little bit too subtle.

This is certainly a unique flight. Not going for awards, but just going to go. You know what they say: Slow and steady wins the race.

You got a lot of fuel...

Bad jokes aside, here's curtain #1!

would "Take Command" be allowed since it doesn't change aerodynamics?

Sure. It isn't really a different part; just a time saver. Don't see how I could deny such a thing. I might get it myself.

could you link the leader board to the individual post by that person achieving the challenge rather than their profile?

Challenge accepted. I'll do it tomorrow cause I don't have enough time today

Is landing (for resting fingers)allowed. And also is ISRU usage allowed (ISRU is damn heavy so it will cost you some bit of fuel to use it)

[nicky4096]

ISRU is not allowed because it allows infinite circumnavigations. landing is also not allowed. for resting fingers, hit Esc and get a beer

[HelmutK]

A complete new flight:

Those are some solid times and an intriguing design. Try a later and steeper descent (nose down around the mountains, or when it'll require about a 40-45 degree angle under horizon). You'll want to cut throttle and might require s turns and/or airbrakes to slow down fast enough, but it might get you under 40.

maybe there are a few seconds in a optimal landing, but unfortunately not 30. I must optimize the start and flight to cruising altitude.

To come under 40s is realy hard. My respect.

I have tested also a modified model with more fuel and flying in lower altitude (21000).

Not realy faster then the normal one in my first flight...only with a lucky suicide landing (11,2G) it was 9 seconds faster and needs 150 units LF more.

I think it takes more time with the extra weight to reach the cruising speed.

So, does that mean I'll have a challenger sometime? (someone else who uses basics?)

[322997am]

Is using rover wheels to power a prop okay?

[Xannari Ferrows]

Is using rover wheels to power a prop okay?

Umm... Good question. Doesn't the wheel have a max radians per second rotation limit? If yes, then it is allowed. If no, then I can't allow it.

And also is ISRU usage allowed (ISRU is damn heavy so it will cost you some bit of fuel to use it)

That's an interesting idea, actually. If you thought you could land, though, you're out of luck. The flight will still be finite, and maybe less than what you could achieve otherwise, but sure. Go right ahead.

could you link the leader board to the individual post by that person achieving the challenge rather than their profile?

I can link to specific page numbers, but the post that their entry is on changes along with every few posts.

I did the challenge but i forgot to include the screenshots

You can bake a pizza on that thing!

It's quite possible you could make a rocket-like takeoff structure and shave a few seconds off. Also, are you going a prograde circumnavigation, or retrograde? The way you landed suggests prograde, and I'd suggest retrograde instead.

Going on the board.

Nice run. If I could give you another rep point I would. Ascents are tricky and even more so with shock cones. Good acceleration is a rather narrow window between fatal heating and loss of thrust. In my experience, between about 9000 and 16000m altitude, reaching speeds more than tenth of the altitude (forgive the unit mismatch) seems to promote rapid disassembly but getting past 16000 without being up to about 1300 means it'll take far longer to reach 1700, maybe even requiring a dive. If your plane is able to hold 1700+, it's probably able to beat 40. My top time involved quite a few reversions to launch until I was in cruise within about T+2min.

[nicky4096]

xannari, be careful with take command. it broke my game :/

[klesh]

Okay fellas, I'm halfway around. I'll update it once she lands. A pretty unimpressive design, no speed records, nothing fancy. Just bored this morning so I thought I'd try it out quick.

Edit:

Okay, that was fun. Here is the ship. I didn't particularly math this out at all, I'm not that kind of player. I slapped together something reasonable, figured the bigS wings would gimmie lots of lift up high, and they carry some fuel too. I think I gave each wing 90. I landed with 280 to spare, not enough for another go around. If I filled the wings full, I could probably do 2 or maybe 3? I used a single whiplash.

Anyway, here are the relavant pictures. I hope you find them to your satisfaction for qualification.

I'm going to be livestreaming an attempt to do a double circumnavigation on just basic jet engines for this challenge.

See it here: http://www.twitch.tv/noname117spore

If the attempt is successful I will be posting it here.

[Xannari Ferrows]

Watching the stream! Grades will be temporarily halted.

EDIT: The Platypus first edition is being built!

EDIT: Smackdown! The plane flew apart, and quicksaves were needed after all, courtesy of Jon! Whoever that might be.

EDIT: For the record, going to the space center mid flight WILL revert you to the last point where you were landed.

don't worry noname117, i'm working on an entry using basics

[Gaming Kraken]

YAY my circumnavigation DONE! No parts lost!

nice!

[HelmutK]

Ok...update

@ExaltedDuck

I've optimized the ascent, reach cruising speed now in T+2min.

Hold altitude at nearly 22500 (3m/s more average speed. 1708 instead of 1705 at 23000)

And realy, i was earlier at the mountains, but...I must use a parachute or airbrake... lost too much time to lower the speed near and on the runway:confused:.

@Xannari Ferrows

Tomorrow i try it retrograde:)

Ok, i think these trying don't count

ok, there is no plane but a good time

SOOOOO close. I'll be honest, I've completed 4 or 5 circumnavs in my record plane, and that time is better than all but my fastest two. And that glowy pic is my favorite in the thread so far.

Hey you did my job for me!

Well, you've let yourself right in the door, so I might as well just put it on the board and end it here.

Did you by chance appear at the silly parade?

This looks like a true endurance plane! I'd imagine with a few modifications, 2 circumnavigations might just be possible.

But until then, your prize awaits you.

Huh, I don't know?

[Noname117]

So, as a couple of you know, I livestreamed another circumnavigation yesterday (again, on basic jets). The flight is below:

Javascript is disabled. View full album

Managed to stay below 2700m this time, with a total time of 7 hours 39 minutes and either 17 or 34 seconds, depending on if you are counting the time until touchdown or the time until full stop. Either way, I massively beat my fastest time and lowest max altitude records from my previous basic-jet-engine-only run.

Speaking of basic jet engine only circumnavigations, I am now offering up a couple of trophies for the first people to circumnavigate 2 and 3 consecutive times on pure basic jet power.

The Mundous trophy, to be rewarded to the first person to circumnavigate twice using only J-33 jets, following the rules of the competition.

The Tiena Trophy, to be rewarded to the first person to circumnavigate three times using only J-33 jets, again following the rules of the competition.

Both of these trophies will be very hard to get, as trying to design a plane with the range to complete 2 circumnavigations on basic jet engines is near impossible for me. I've built these trophies mainly to encourage innovation and more competition in the basic jet circumnavigation realm. I hope some of you guys decide to join me with using just basic jets for circumnavigations. I hope to see your attempts!

[HelmutK]

Puuuh...i did it

With a parachute it was possible to low speed on runway much faster (but it took several attempts).

Here the results, a little Video will follow soon.

Maybe retrograde is even faster. I'll try it.
