Everyone: Is it a spaceplane?
Shadow Zone: Well yes, but actually no.
Of course the fairing is necessary. It builds suspense until you can finally open it and reveal the spacecraft. Isn't that why they have fairings in real life?
Jonassoe ikr
Damn your creativity never ceases to amaze me.
I need to watch this video...
Again!
May I give you a couple of pieces of advice?
1) If you plan to make a Spaceplane to Duna you have to make sure it has much larger wing area than it needs to fly around Kerbin. And here I mean that it has to have a *ridiculous* amount of wing area, like a ,,flying wing" profile.
2) When building any kind of plane try to look your CoM (Center of Mass) and CoL (Center of Lift; in real life: wing focus). Just like in real aviation, planes have three balances: constant, neutral and unstable (think it as like with this experiment with a ball in kitchen sink, flat table and mountain).
a) When Center of Lift is in front of Center of Mass, your plane is unstable statically (strange name, isn't it?🙃), that means it can fly normally but only, if you don't ,,touch" it (here: e.c. trying to pitch (,, Pitch" in real aviation is called ,,tilt")). If you do, plane won't recover from this situation by itself and it's up to you to do it. It's hard even on Kerbin, so think how hard it is on Duna.
b) When CoL is in the exact same place as CoM, your plane is ,,stable statically, but not dynamically" (or ,,neutral statically") - that means it won't doomed with even the smallest of manoeuvre, but it won't recover from this as well.
c) If CoL is behind CoM, then it's brilliant. In aviation we say it's ,,stable statically and dynamically", so if you make small mistake while flying (I do them, everyone does them, SAS (fun fact: it's equivalent in real aviation is *not* Autopilot) does them either), so don't be shy) plane (sometimes even without SAS) will recover by itself. Of course you can even count how static it can be (staticall stability has one of only three values: -1 (unstable statically), 0 (neutral statically) and 1 (stable statically), as it's only a tendency, and dynamical staticness is a tendency, whether your plane will recover or not (it doesn't exist when there's no statical staticness)), but if anyone does it, let him/her throw a stone first.
3) while re-entring in atmosphere try not to lose speed at any cost. Slow down in higher layers of atmosphere, trying to avoid doing crazy stunts with it and slowly decent. Then, when you're in Stratosphere (let's say it's about 10-12.000m (I mean I don't know, but it works there)) it's the most efficient to use any kind of engines there (excluding those providing subsonic speeds). Drag is small, but there is still enough oxygen to sustain an air-breathing flight - what else you would ask for? Try to keep in that limit of altitude (when you're about to fly out of this limit click Prograde and then, when plane start defends to just below the withe 0° line on Navball return to that first mode) and not fly faster than 1200m/s. Is it worth it? I will tell you this way: with this tactic I was able to get from KSC to North Pole using the Ravenspear Mk3 in around 3 minutes, and make a constant no-refueling flight all around Kerbin (it took me 20 minutes and I still had 25% of fuel I was starting with).
I mostly Use parachutes as "extra wings" for the landing, so i can land with less speed and not crash
i tried that once. my problem initially was that i couldnt even slow down enough to be able to deploy them
You never stop to amaze me with your designs, I tried something similar, never got it to work, nor was it close to half as elegant as what you come up with! Keep it up Shadowzone and stay safe!
Dude...thats a kickass idea. I've tried rover in plane....never plane is rover. Your killing it.
Well that was a true Kerbal launchvehicle!

Im a simple man
I see yeet, i click
I've been wondering about making an aero & gyro stabilised rover, so it maintains a preferred angle when hopping along planetary surfaces.
Nice video during this chaotic time irl! How are you handling it?
Thanks for asking. I'm doing well. None of my family got the virus so far. Austria really put the kibosh on the spread early on and it worked.
ShadowZone for a second i thought you said Australia lol
@@ShadowZone glad your country handled it well!!
KSP Aero 101:
- Enable CoM overlay in SPH. (The yellow ball);
- Enable CoL overlay in SPH. (The blue ball);
- Move fuel/wings around so the *yellow* ball is always infront of the *blue* ball;
- Done.
Tip: Get RCS Build Aid mod so you also get a *red* overlay, which is "no fuel". This helps gauge at a glance whether CoM stays infront of CoL even when low on fuel.
Edit: I usually build my planes so the blue and yellow ball centers are within roughly 1m of eachother, with the yellow one infront of the blue one.
Another fantastic video 👌 I can say from experience that trying to land spaceplanes on Duna is very challenging unless it’s designed to fly only in Duna’s atmosphere
Awesome contraption!
One of the darn cleverest things I've seen... and it looks great too!
Wow you know how to have a good time during these times! Hope you are doing ok
And this is why you should put retro-thrusters on your Duna airplanes.
Transfer as much fuel as possible to the front tanks. Extra weight in the front will make the plane more stable in re-entry.
I did not expect the rover to come out like that
If your plane flips over, the center of mass is too far back. You can improve stability by pumping fuel forward. While building aircrafts I always check how the centre of mass shifts when tanks are emptying.
he probably knows that
haha, this exact problem i had 2 years ago when building a base on Duna.. too faaaast!
Spectacular design, congrats...
That was so awesome!!!!! :)
The rover and how it works with the space plane is genius!
The actual space plane though... maybe not so much? 😂
But it’s all just refining the engineering and aerodynamics at this point. A future version will only be better! Excellent work!
This is awesome! :3
Humans respect rocket scientists, Kerbals respect airplane scientists. ;)
Good landing in the end. It's cool that you could touch down at only 95m/s in Duna's thin atmosphere.
Oh! Nice use of part of the plane as the rover. :) I thought the whole plane would drive around, but of course that makes it hard for the scanning arm to reach.
Both reentries have the plane flipping around. I wonder why? _think think think_ Ah! It's probably because the cockpit doesn't couple directly to the next piece and so the game treats the forward cargo bay as open, counting all the rover parts as drag. I was positively horrified when I heard KSP2 will use the same aerodynamics model.
Amazing!
Hey Shadow good to see you. Hope you and your family are doing well.
This is probably as close as you can get to multi purpose shuttles in Sci Fi.
Wow....
You are a real engineer
I always stuck with big rover to get enough wheel spacing.
It's amazing to solve it by hinges or actuators
I need to update mine
I had something similar once, but with dedicated vtol-engines, which made landing and starting a breeze ...
Yeah.... Easter egg.. that's where my mind went first..
That rover is so ganster!!!
Not sure if anybody remembers Thompbles' "Long Term Laythe" missions (from like 2013) but this is basically a more advanced derivative of his BirdDog Aircraft/Rover Hybrid.
I'm sure he'd be tickled pink if he sees this.
The stability issue was due to aft CG, pump fuel forward if you can if the plane is trying to fly backwards.
Your control surfaces are on backwards. The wider section should be the root and the thinner portion the tip. It's about leverage. Having the surfaces taper down toward the tip helps to equalize the force acting across the whole surface. Therefore, the tip provides the same amount of force as the root. Your craft will also be more stable this way.
KSP does not model this
@@sebastiaomendonca1477Yes, it does. Ksp doesnt model aerodynamics perfectly, but such simple things like this are easy for ksp to handle.
@@milkhbox It doesnt model things like that. Its way too specific
My success with wheel landings on Duna is maybe 5%. Frustrating but highly addictive.
This is type of spacecraft a interstellar colony would use
I shall confirm, the engine IS called Wolfhound.
Is it just me or your video making skills have increased 10 folds?
ShadowZone if you want i can teash some simple rules for plans
What visual mods were used here? Love the cloud effects!
EVE
Duna planes need a hell of a lot of wings and to fly really slowly ( or maybe mine just had insufficient thrust for the amount of lift). I eventually gave up and hyper edited my plane there for testing before launching it
Edit: ok yeah... It was just mine which was slow
im so early the video hasnt even rendered.
fuck
Shadowwww zooomnnnneee
You could've just refuled the plane at the end, but you are right if there is a rover why don't use it. Anyway have a good day ( ;
Can this be done without clipping the wheels inside the cargo bay?
Welp... One time (day ago actually) i decide to build my first SSTO and after multiply crashes and due to unstable aerodynamic profile i chose to close my space agency called "Space Colonezation Company" (yes... colon I zation, i know ok? But it's hard to draw things in Photoshop!)
200iq
when i see... wtf and laugh
change formation，it's gattai time!
Äpic
No one ever gets Duna landings first time :)
I did get a Duna landing first try once... with a plane that had massive wings and very strong landing gear specifically designed for the task
Sebastião Mendonça Oh that’s cool!
Looks like your CG (center of gravity) is to far forward of your CL (center of lift that) I.E. the heave rover batteries with no rear counter weight .. will cause the tumbling .. you should have unfolded your rover wheels dropped your landing legs and towed the whole plane back lol
The only reason I’m building my first PC is to get KSP to look at least close to ShadowZones installations, has anyone got any recommendations for what I should use to get EVE to run well?
Up until November I was doing my stuff on an i7 6700 from 2015 and a Radeon RX580.
Key upgrade is RAM! KSP even now on my very powerful new PC hogs sometimes 20GB and more.
ShadowZone thanks!
any chance we could get the craft file? I would love to reverse engineer this so I can make one in my own style.
Sure, I'll upload it to kerbalx as usual. Link in the description. Might take a few hours though until I'll be able to do so.
@@ShadowZone thank you
kinda looks like your profile picture
Is that a stock engine, or is it from Making History?
It's from MH. Closest stock alternative is the Poodle.
Your plane skills don't suck, just your landing on rough terrain skills.
It's a rover plane that's really crazy. Both work so it's not a build problem!!
Plus at least yours a PRETTY mine all look like shit!
Bro we need to talk about your fairings...
Where is invictus?
lol the plane putting a leg up to get ore looked a bit like a dog at a treetrunk doing it's business ^^ EDIT: This is the worst sentence I've ever written and I'm sticking by it.
desperate for help. trying to recreate this and its going well, i dont have the dlc needed to do his craft file anyway-
the cockpit rover despite having 2 decouplers holding it in place still wiggles like a wet noodle no matter what i do , i clearly lack the understanding or am missing something and if someone who knows their shit reads this and can offer advice it'd be greatly appreciated
