Setting The CIRCUMNAVIGATION World Record in Kerbal Space Program 2

How did I get mach 122? Well, 4200m/s is mach 12.2, and distances in the ksp system are 1/10 that of real life, so 122!

ikr

[@nork7045]

I know that this comment is 1 year old and you've probably became a wiser person by now, but that veer is clearly not the result of turning on one engine before the other. The initial spin it gets as a result of that is neutralized and only after it gets going straigh again the plane starts veering to the side again. Probably something to do with the landing gear.

[@KrazyKaiser]

That final trajectory was mindblowing, you could have scraped across the runway and STILL escaped Kerbins SOI you were going so damn fast.

[@NOT_A_ROBOT]

that also happens on ksp1's land speed record, although they used wings to push the craft downwards. also, it was so fast they had to use multiple fairings to block the heat

[@LowIntGamer]

@@NOT_A_ROBOT Land speed record might be something i try later on nice to see we watch some of the same youtubers

[@thatsstoguy]

I bet the reason why the first plane didn't work is because the jets were blocked by the elevators.

[@ReidCaptain]

I kinda decided to skip over the real reason that I didn't want to use jets, and it's that I can't operate them in the upper atmosphere where there is less drag, so I would be stuck around only 15-2000 m/s or so

[@phoggishadow6008]

hi there :))@@ReidCaptain

[@DecidedlyNinja]

I was so proud of Reid for making a plane with horizontal stabilizers. Then he made a nuclear rocket plane that throws its reactor at the space center.

[@hatman44]

Well since there's no heat in ksp2 yet, you could do that in a lower orbit with an air and fuel mixture, you just have to make a craft that doesn't have alot of drag Btw you should try a speed record to the moon and back for funsies lol

[@ReidCaptain]

True, but getting up to 4000m/s under 30km might be asking a lot. Will consider a moon run!

[@Roaxial]

it might be possible to get it quicker by doing 2 circumnavigations, the first one to build speed and get into position, and the second one to actually get the time

[@ReidCaptain]

Time starts from liftoff 😉

[@Roaxial]

@@ReidCaptain with 2 circumnavigations i think it would be reasonable to divide the end time by two, which would still be faster assuming you can get the extra fuel up there without loosing too much time

[@ChargeQM]

​@@Roaxial But that isn't how it works, you have to start on the ground and end on the ground.

[@mrmunchkin2181]

[@zunnen4347]

the whole point is to have a craft that starts and lands on the same spot to truly circumnavigate the whole planat once

[@phyllostomus]

You should upload the unedited full circumnavigation if you can. That way there's a good standard of comparison for people to compete with.

[@Audaylon]

for sure

[@OrbitalGirl]

ok but the speed of sound isn't affected by the size of the Kerbol system, so speed of sound would still be sqrt(gamma*R*T), so tho it wouldn't necessarily be the usual 340 m/s of low atmosphere it would probably not be mach 122 checking Earth standard atmosphere tables and assuming similar atmosphere composition, 60 km above Kerbin would probably be similar to ~80 km above earth bc density and pressure, so that gives us a speed of sound of ~282.5 m/s. So based on the fastest speed I saw while watching the video (~4550 m/s), we get Mach 16.1. so pretty fast

Your engines are partially occluded which matters in KSP2. …can still angle wings behind the engines even post-patch for weird vtol-like thrust at the cost of engine power…but you can always just sepraton the deflector-wings once you are airborn until we get robotics parts.

[@Glitch315]

It's higher than 12.2, because you are on the tip of the atmosphere. I'm assuming you used the sea level reading of mach 1 to get mach 12.2 from 4200/340. But remember that mach 1 is not constant, it changes depending on the density of the medium. At 70000km the speed of sound is about 290m/s and since you are pretty close to that it should be 4200/290, which is mach 14.5

[@ReidCaptain]

I mean technicallyyy there is nearly no atmosphere at 65k in ksp, so it would probably be far slower than that anyway, making it a way higher mach number

[@warriorsabe1792]

@@ReidCaptain Speed of sound actually doesn't depend on air pressure, only the composition and temperature

[@Powderlover1]

that seems like a dumb way to measure the speed of an object, but I’m not a rocket scientist, and I use Fahrenheit soooo

[@Glitch315]

​@@Powderlover1 It's not to measure the speed of the object. It's to know how far away you are from the speed of sound. That's important because aerodynamic forces change drastically when approaching/passing the sound barrier. Airspeed is still measured in m/s, knots, etc. People just like to show speed as X times the speed of sound sometimes to add wow effect.

[@yoinki_sploinki]

Seeing this done genuinely is really impressive. If it were me I would have just made a simple kraken drive. Keep up the good work!

[@dontworrybout2664]

For some reason it wanted to veer off to the side while giving it tens of thousands of pounds of asymmetric thrust.

[@MonkeySimius]

That's awesome. I'm really enjoying your content. I also appreciate you leaving some of the bugs still in the game in your footage. I do want to buy the game and play with this version of KSP but I also want to have fun when I do it. These bugs would likely sour me on the experience if I played it as is... So seeing them reminds me of why I am waiting and is preventing me from jumping in too soon. Long story short: Thanks.

[@lonnierh0dgejr41]

to get faster, you need as low an orbit as possible and do your reentry burn backwards enough to get an overshot of the airstrip. if you can, you need a jet engine to speed up enough that you come in fast but not too fast so you can hit parachutes at the last moment.

[@medoche]

Nice challenge, hope some peoples will try to do it too I tried it in ksp 1 few days ago, It took me roughly 1h30min to make it with a Concorde I made flying at Mach 2.7 at around 12 000m and landed back at the ksc

[@AshSteelFist]

[@user-cr4sc1ht9t]

The reason why your earlier designs kept veering off runway and unable to take off has to do with your landing leg configuration. If your nose gear is lower than main, or your gears are behind center of lift, that makes it impossible to take off. That is exactly how Space Shuttle looks like and it's ideal for the Shuttle, because they don't want to even be able to go around, but not so much for planes.

[@juliuscaesar5197]

In ksp 1 I just used whiplash engines like two of them or 4 and it would get me to 1400m\s on like 500m of altitude after which the plane just exploded from drag so I guess doing that and keeping the speed below exploding levels would work

could it be faster to stay low in the atmosphere, use a lot of horizontal thrust for maximum speed and use wings to do the pushing down bit?

[@nightbringar7558]

I know this might seem silly but this video finally allowed me to intuitively understand why it's so hard to launch a rocket into the sun. It's something I've always begrudgingly accepted as fact even though it made zero sense. The amount of fuel spent pushing the rocket straight towards Kerbal so that your current relative velocity wouldn't throw you into orbit or break out of orbit made it all click. Thank you for your crazy engineering videos!

I think the booster idea is good but I think it would've been better if you used them to gain high ground speed and decouple them to lift into the air just under momentum, once you gain high enough altitude you could use a jet engine to keep yourself moving

[@genesisreaper2113]

hey, noticed on some of your planes that they were kinda unstable, if you enable the center of lift/mass overlays, and make sure they are aligned (or the center of lift is slightly behind) it'll be much more stable!

[@TheArtikae]

This, soooo much this. If you want to make planes, do this. Making planes without it is like building rockets without symmetry enabled.

[@clashofcraft9725]

To prevent you're planes to go spinny on the runway, you need to turn of autofiction control on the front landing Gears, yeah, this is a bug...

[@psikho144]

Idea: Make a spin launcher in KSP2

[@spankyjeffro5320]

I would also add to the challenge that the design must work IRL, no jank, and you must actually land on the runway then taxi to the main building.

[@irekkrzyzan3956]

the little lander/plane thing is realy cute

[@theriddler8375]

you could turn off friction control on the front landing gear to stop the instability

[@Hellsarchon]

isnt the darkest blue the end of the atmosphere, and the black with stars technical "space". Because at 40,000 meters, Kerbin has an atmosphere of 0.001, and at 50,000 meters its 0.000 atm. So i think for a challenge like this to be relevant keeping it under 49,999 meters is key. As you are still fighting an atmosphere, without venturing too far into a 0 atmosphere zone and cheesing the whole thing.
