The longest ramp jump on Kerbin


Recommended Posts

After doing this jump in my jet ATV mk6

and asking if it was the longest ramp jump ever attempted in KSP it became apparent to me that people want this to be a competition with clear guidelines so here i am to provide such a competition.

So who thinks they jump the furthest?

Entries close on the 29th of Febuary

Da Rules:

1 - Only stock craft can be used.

2 - No Aerodynamic modifications allowed. (no wings/control surfaces)

3 - No assistance while in the air. (Engines off at the start of ramp)

4 - Jump must be done using the small lip near the SPH to the right of the run way.

5- Vehicle must carry a kerbal.

6- Vehicle/kerbal must land successfully and survive the jump. (if the kerbal lives it will be accepted)

7- Jump must be recorded with screenshots/video

8- Craft file for vehicle used must be provided.

Good luck and have fun.

You broke your own rule 3 - no assistance while in the air.

You used jets which take a long time for their thrust to drop off. You had upward thrust for most of your jump.

About the only way I can see around it would be for all engines to be detached before hitting the ramp.

I got about the same distance as you without engine thrust while in flight with this:

The carriage was to get it in place and lined up. Then fire the engine. Drop the engine just before hitting the ramp. Then deploy the shutes a moment before hitting the ground.

I believe he didn't... He used jet engines, but stopped them by cutting of the air intakes which stops jets instantly. If you watch the video closely, you can see his throttle remained all the way up the whole time, so it must have been the intakes.

Ah, maybe. If so then that's kinda OK but that's not possible if other engines are used. I think the only way to be sure is to drop the engines.

yeah sorry didnt mention i used action groups to shut that all down so i could keep the power right up to the last moment.

The action group to toggle the engines shuts their air intake off to kill them, i am sure it works the same on rocket engines only with the fuel supply killing them instantly, should be fine as long as you set it up to shut them off completely, otherwise just set them up with a decoupler, less weight in the air after all, i am going to make an attempt with moar power later, i think the end of the runway is doable haha

Also rule 2. The OP's craft is festooned with strakes. I'm sure they were meant to keep it pinned down during acceleration, but they provide lift once the nose is high enough.

Which craft are you talking about exactly? the one that inspired the challenge or the one i used in the challenge lol?

The craft i used for the challenge i removed all the aerodynamic wings and added extra reaction wheels to try and compensate for the stability loss as well as an extra engine for more top speed.

The video in the first spoiler is in no way viable for entry into the contest.

Anywho here is my second attempt, this time more power, added a lot of down force in the shape of wings that are decoupled just before the jump as well.

I felt like taking a few meters off the jump distance im not 100% sure where i landed but i know i went past 11 of the light markers on the run way before landing.

Yeah, I was referring to the one that inspired the challenge.

Uhh... minor problem:

I'm hitting the ramp at 900 m/sec and jumping off into the ocean.

Does it still count if the vehicle goes "kerplunk"?

Thanks,

-Slashy

Haha you wot?

sadly no i did make it a rule that you have to be able to land the craft, i wonder if there could ever be a way because damn thats far.

btw how did you get to 900m/s :confused: ? your twr must be off the chart

It is... or rather *was* In my attempt to make it more stable, I've tinkered with it to the point where it no longer works :(

That isn't an official entry since I didn't fully document the run (everything was happening way too fast)...

I'll keep messing with it and see if I can make a run worthy of posting...

Thanks,

It`s probably driven by the kraken itself. Slashy made the kraken his little pet. I always see him posting infiniglide and krakendrive entries ^^

I myself built a solid booster version (the true kerbal style with explosions :P). Which gets to about 270 m/s at the ramp and lands at 1.5 km with stock aerodynamics. I also tried it with NEAR but it gets a lot further with stock.

But it`s missing the capsule now, the rules keep changing so fast :P

Keras,

Actually, nothing that fancy. It's just a lot of O-10 engines pushing an almost- massless cart.

the difficulty is in getting it to stay on the ground. It's just sorta skipping along the surface under boost, then sailing over the jump. I'm having a hard time taming it...

Perhaps not exactly what the OP had in mind but I don't think it breaks any of the rules...

I don`t think there is any definition where that qualifies as a jump. Clearly breaks rule 4 imo :P

I might be able to get my solid booster cart to the end of the runway. Will test further tomorrow.

Btw I had my boosters explode the whole craft on takeoff but leaving Jeb in his seat, firing him to the shore. The seat exploded and Jeb survived somehow (2.5km distance) but I won`t count that as valid ^^

Spoil sport :wink:. It did use the lip at the right location in that my 'thing' was on it to get the angle right. It just wasn't moving terribly quickly at the time.

I've got to either give up or start from scratch :(

No way I can make this thing survivable landing in the water on the rare occasion it actually makes it that far intact. I don't have the heart to strap a kerbal into it.

Best,

-Slashy

There has to be a way!, maybe a smaller version of the suspension used on my jet ATV? it was originally used for traversing into water, can drive it in at 50m/s.

would cut the jump distance a little bit with how far your jumping i dont think it will hurt :P

Edit:

Ohhh try making intake suspension like this guys craft uses.

There's no rule (yet) against 'chutes. Strap one on and use it just before landing.

Do this, i am not going to be making a parachute rule unless people think i should.

Here's a more officialish entry...

I can make it go a bit further with a couple more engines but then it often lands in the water.

And thats great man awesome attempt, going to be hard for anyone to even try and beat that!

Id give you some rep but i cant give you anymore atm.

btw do you have an idea on how far you went? i will add your attempt to the OP
