fastest jet in ksp *UPDATED* 2/28/2019

[ExaltedDuck]

check out the circumnavigation thread. A lot of us taking part in it have built jets that cruise at 1720-1740. That's a bit over mach 5. I've gotten my own over 1750 in a powerdive. Rapier in air mode, no oxidizer, low drag, high altitude.

Yes, but per the rules of this challenge we cannot use rapier engines or go above 50 km. So

oh. well then in that case, there's this from another thread that was kind of an offshoot.

top displayed surface speed in-flight was 1495.5. (other parts of that challenge were single engine, no non-cosmetic mods, a successful no-parts-lost landing, and speed taken from the F3 screen) Sometime tomorrow I'll see what I can do if I lift those restrictions and really unleash the beast.

[Bioman222]

This baby hit a little over 1500 m/s in stock KSP.

I'll come back with a picture of it with UI open.

[Sharkman Briton]

I made a plane, that, with unbreakable joints and ignore max temp enabled (I didn't bother testing it without) reached massive speeds, it might've been like 1900m/s or 2000m/s

[ExaltedDuck]

So I took my fastest circumnavigator (it held the world record briefly, but was beaten by 2 seconds and a subsequent rule change has made the new record unassailable), swapped out the engines for whiplashes, stuck some lower drag flight surfaces on it and put this together:

I could have sworn I saw it hit an even 1530.0, but the best I managed to screencap was 1529.7. And it has a few draggy parts that were necessary for the circumnavigation challenge but not this one, so I'll probably be back soon.

[fire219]

The best I've been able to achieve is 1469.0 m/s (though I didn't get it screenshotted), despite several tries and drastic methods to reduce weight/drag.

~1500m/s seems to be the maximum that can be eked out of the stock Whiplash turbojet. At the needed altitude (~20k) and these speeds, it's thrust is negligible.

I had just learned that fairings make the best nose cones and had to try it out.

I didn't know about the challenge, but I think this qualifies?

mach 5.06 according to the Kerbal Engineer and the last screen before I blew up.

highest speed over land 1483 m/s

oh and hai first post

Fairings have been implemented for stock pats so they are allowed and ill add your entry in to the leader board

[Lego8_bit]

OK I will be updating the Leader board with all entries that are recent

bioman222 your using RAIPIERS with is forbidden in this challenge and makes your attempt null and voided.

sounds like you were messing with alt f12 which is forbidden but its a nice try

if its the same craft you used i will update the leaderboard otherwise it might not count

[Nefrums]

I made a very simple ship out of a mk1 cockpit, 8 precoolers, 7 turbojets and 6 fairings.

I got it up to 1554.7 m/s just before it exploded.

keep up the good work guys >

[partyphoenix]

this is my prized aircraft, the HSP-VII. It got up to mach 7.30 at 25,000 alt 25000

[AeroArchonite_]

Got my flying wing up to 1036 m/s in atmosphere, though it was for a challenge, so I could prob get its speed higher.

I got it to 9036m at 1172 m/s. Then it exploded.

[Yakuzi]

I fiddled around with Nefrum's design and with some modifications (and no Jeb to disintegrate) I managed to squeeze it up 1,560 m/s (Mach 5.28 according to KER). Overheating is definitely the limiting factor here... if only the turbojet could maintain its max thrust at higher altitudes.

EDIT: Anyone know what the most heat resistant stock parts are?

Edited November 1, 2015 by Yakuzi

[legoclone09]

I think a pointy heat shield would be very heat resistant, if it existed. Or you can Offset and Rotate heat shields to make that effect.

[Yakuzi]

a heat shield

mind=blown... thanks mate

[legoclone09]

I can *probably* throw together a heat shield nosecone. I actually should do that.

[Lego8_bit]

sorry if ive been away from this challenge a while but i will update the scorebords for ya

[andykhang]

Using 2 advanced turboramjet and 8 radial scramjet, i managed to 3,248 m/s before i flung myself out of kerbin

No FAR by the way. Forgot to do from start to finish

http://imgur.com/a/e7rmP

 

Edit 1: managed to mach 10.67 (3628 m/s) with some slight modification. Again, still flung myself out of kerbin. Proof will be showed in the previous album

Edit 2: with 8 air intake (4 of which was hypersonic), 2 advanced turboramjet, 8 radial scramjet and 5 (1 inside the plane) houdini. I have pushed myself to 5969 m/s (17.4 mach) before exploded in mid-space. Guarantee real deal.

Cool Challenge!

Guys iam now trying to reach 6000 m\s ! and iam on 3000 !

Pics?

 

[algwat]

Not really sure if this config meets the rules, this craft made 4200m/s at 36Km on LQ fuel before it auto switched to LQ/OX mode.

So, I'll try again to limit ALT to 30km and see how fast it goes....Let me know if it meets the challenge. hmmm... 6000m/s ???

1000m/s  2000m/s....3000m/s . . .4200m/s....oh! and orbit and can leave kerbal to a solar orbit....

[ihtoit]

pretty sure the rule says no Rapiers...

 

Oh, looky, right there:

" 3. No rapier engines "
