Fastest Speed in Ten Seconds [STOCK]

[dogon11]

This challenge is to see who can reach the fastest speeds by burning their engines for no longer than ten seconds. Stock parts only.

Rules:

1) Stock only.

2) No magic turbines or RCS.

3) Can be launched from pad or runway.

4) Can either fly or be on the ground, it is up to you.

5) Three screenshots are needed: Before launch, at the ten second mark just after the engines have cut out, and once the vehicle has come to a halt at the mission report screen.

6) All kerbals must survive all the way up to the point the flight ends.

Leaderboard:

Fermun: 346.5 m/s

Vostok: 327 m/s

Pushingrobot: 318 m/s

Madmak: 307.9 m/s

Hebdomad: 302 m/s

Analogy: 290 m/s

UmbralRaptor: 290 m/s

Rich: 288.6 m/s

Dogon11: 280 m/s

Kerbalnaut: 280 m/s

SteevyT: 266 m/s

Apotheosist: 254 m/s

P512: 241.4 m/s

Knyght: 241 m/s

Sorry for double posting here is my result.

You seem to have encountered a bug...

When you use the restart flight button, it messes up fastest speed achieved.

Could you redo the end flight pictures so that we have an accurate speed?

[Cooly568]

My after rocket cutout showed the speed.

187.1 M/S

[dogon11]

Allright, adding.

I was just concerned that it might have actually gone a tad bit faster then the screenshot shows, but okay.

[Knyght]

Here is my more minimalist approach. Could have eked out an extra 10m/s by pressing F1 a fraction of a second later, but the max speed in the end results seems accurate enough.

[Apotheosist]

Damn, someone beat me to it! I made a similar craft to Knyght, although even more minimalist, here it is. 254m/s final speed. Fuel runs out bang on 10 seconds, which is convenient I used lithobraking to ensure kerbal survival. Didn\'t manage to get a screenshot on 10 seconds exactly, will try again.

[dogon11]

Lithobraking?

[SteevyT]

Top speed of 228. If I could keep control it would go faster.

On the pad.

Just after burn out (I lost control, top speed was around 7 seconds)

On the ground, they survived.

Top speed.

[Knyght]

Damn you, I was just about to try that! In fact I already had that designed first but I couldn\'t fly it without ASAS because I\'m terrible.

Also, yes, the running out of fuel at 10 seconds is convenient indeed... I wonder if it could be scaled up without adding weight...

I also tried a cart for a land attempt but it does like to flip around and explode a lot...

[infatuatedPP]

Here is my attempt. I call it more boosters. Max speed reached 292.3 m/s

On the pad:

Max speed (Sorry, cannot cut off engines)

Final screen (Only a second or two after the 10 second mark

[pushingrobot]

I\'m thinking you also need a 'no RCS' rule...or else you\'ll end up with this:

[SteevyT]

New record 266m/s.

On the pad.

Just after engine cut off.

Any landing you can walk away from....

Top speed 266 m/s

Here is my attempt. I call it more boosters. Max speed reached 292.3 m/s

On the pad:

Max speed (Sorry, cannot cut off engines)

Final screen (Only a second or two after the 10 second mark

The Kerbals didn\'t survive though....

[dogon11]

Here\'s my attempt, propelling me to 280 m/s.

[pushingrobot]

Here\'s a more traditional rocket:

[Rich]

288.6 m/s

290!

I guess I am not quite sure I understand rule number 6. Do you mean that the crew has land safely, or do you mean that the crew must survive until you hit the end mission button (which can be anytime in flight)

Most people have interpreted it as 'land safely.' Nothing\'s been said about stage separations so it\'s pretty easy to just throw in a decoupler and a parachute to satisfy that. Having to land the entire craft safely would make this much much more difficult.

BTW, I\'ve made another craft for this challenge but I can\'t load it up on the launchpad without the thing falling apart... Anyone have any ideas?

May I suggest putting decouplers on the bottom with fuel tanks under them as stands?

[Cooly568]

I crushed you guys.

READ THE RULES!

Rule 1: MUST BE COMPLETELY STOCK

[UmbralRaptor]

I assume that if I run out of fuel before the 10s are up, my max speed (290 m/s) still counts?

edit: feh. I had a 313 m/s design, but it was actually burning for ~10.7 s. This 302 m/s design is doable, though:

Edit 2: I need a clarification: do the engines need to be off as of the start of 10 seconds MET, or the end? With my current designs, this is the difference between 316 m/s and 327 m/s (bracketing pushingrobot\'s 318 m/s). Also, I\'m fairly sure that these exploit fuel bugs in 0.15.x. Is that an issue?

[hebdomad]

I got 302m/s

Trying to fine tune it at the moment, I\'ve still got 'wasted' fuel I\'ve not burnt after 10s....

*edit*

>< I might get back to this one once I\'ve got my three screen shots.

[Guest]

I re-attempted this and got 280 m/s. (Note how screeny was taken a second before 10)
