ksp how to make a stable plane

@gokcet @DANKTER I usually run my front wheel override friction on 0.3 when the front gear has steering disabled, it needs lower friction. Usually, having one or two medium-sized intakes will more than suffice on a regular plane. @gocket the reason why your solution works is because you are counteracting the imbalance of friction in the wheels as they wobble. Intakes aren't something usually causing planes to fail, however need some thought. And start small. The BAK Karmilla. If the fuel flows from the. Another pointer is to make your wings larger with the same amount of control surface. +1 for "If that all fails, you may try building your plane lighter and with mightier (or just more) engines, so it just doesn't have the time to start misbehaving on the runway before you bring it up in the air." front, then it automatically disbalances the weight moving the weight to the back. Can you check what happens if you swap in larger gear? Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. User without create permission can create a custom object from Managed package using Custom Rest API. In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. Tutorial: Basic Plane Design - Kerbal Space Program Wiki If you're going for full VTOL you need to have a TWR > 1.0 at take-off weight; adding more vertical engines will make vertical landings easier and (if they're air-breathers) will make it possible to operate at higher elevations. You've landed. Check out Mike from Merrimack, New Hampshire as he explains to filmmaker Rod Webber what' For what it's worth - watching 1.2 pre-release streams, the upcoming changes to SAS are profound. Even though it just spawned. CoL (Blue ball) position relative to CoM (Yellow ball) is very important. 5. How to keep an airplane stable on the runway in Kerbal Space Program? Your plane is almost finished. It is also said that a good landing is one you can walk away from. @TheEnvironmentalist No clue, but it doesn't need to be much because it's a feedback loop. If I'm running something with a long delta-wing layout, I'll then use canards and have the dynamic instability to allow for manouvering; if it's something without a lot of pitch inertia, I'll go tail stabilizer. So you want to make a plane but all your contraptions explode on the runway, crash into the runway a few seconds after taking off, crash into the side of the runway, crash into the ocean after doing a tight turn or otherwise fail to do what you intended? Another way to manage this is to mount your wings above your CoM. Drive gently off the runway and use the huge grassy field to take off, without care in the world about the plane veering to a side. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. The main challenge for hover control is to keep the craft horizontal. You don'thave touse their fuel capacity you might want to leave them dry if they're not symmetrical to the CoM. In 5e D&D and Grim Hollow, how does the Specter transformation affect a human PC in regards to the 'undead' characteristics and spells? As you reach 100m/s, hold S to pull the stick back, and you should be in the air! The more intakes added, the higher a plane can go before a flame-out, which makes multiple intakes a must on SSTO spaceplanes. Clear editor. For more information, please see our I'm finding it quite surprising you didn't manage to get the plane to fly yet. First off, make whatever you want, just, start off making sense. QAnon follower explains that Trump is the shadow President and James How do I make aircraft stable & smooth to control? You can pick the main cockpit and rotate the whole craft with it in SPH to see where your CoL will drift. Cookie Notice Once you got a hang of these, try bigger stuff. You cannot paste images directly. Privacy Policy. Yes, although they have only been flown with nearly full tanks. Try not to make your first airplanes longer than 3 MK1 fuselages. Build yourself a plane. It only takes a minute to sign up. You should be able to navigate fairly readily, and with the superb efficiency of jet engines, you should have plenty of fuel to go anywhere you need to go. Now I have a plane that will fly around the world at an altitude of the low-20s. Upload or insert images from URL. You can horse hundreds of tonnes, up and down both, with the standard canard pieces. But it flies horribly, it's all over the place even with SAS on it doesn't fly even remotely stable. The twin-boom design is one of my favourites, largely because it looks cool. Smaller wings on the cockpit can be good. Kerbal Space Program max Surface Sample storage? Center of Mass - The average of all weight on the plane, this tool will show where gravity will pull . What is this brick with a round back and a stud on the side used for? Keep pitching up as you approach stall speed. hope you and others find that useful in the future! They can be placed on wings. Then this tutorial is for you. 2. If you have more than one engine, you can get asymmetric thrust at low speeds. How do I make aircraft stable & smooth to control? On 11/1/2018 at 10:54 AM, Brikoleur said: On 1/25/2019 at 4:03 AM, panzerknack said: This thread is quite old. My question is really about controllability. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. Powered by Invision Community. Unless you are using canards (not ideal for lots of reasons, IMHO), adding elevons will pull the CoL backwards since they also provide lift in their neutral position. That's what this guide is all about, so we're not talking about VTOL rockets that don't make use of wings to produce lift. Remember the, fuel flows from the front in KSP, so you might want to start off with the CoM in front of the CoL. You can park a ship into an elliptical . That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Designing a First Plane - KSP Beginner's Tutorial - YouTube Better still, three screenshots showing side, top, and rear views. They sometimes coincide with ailerons on some, more space-economical, aircraft. In particular, there's one constraint that needs special attention: centre of mass, and the invariance thereof, as you burn fuel. Getting all of this into one craft is a pretty intricate business, however. I had my rear wheels mounted on the tail, and it seems the taper of the tail messed up the angle of the wheels creating instability. http://kerbalspaceprogram.com. Guest, Try not to make your first airplanes longer than 3 MK1 fuselages. Then: I hope you've found this short tutorial useful. When you're close to it, INCREASE THROTTLE until your rate of descent nears zero. (Yes, you personally, you lucky thing! Whether VTOL craft arepracticalor efficientcompared to other solutions is a different matter -- and to be perfectly honest, I'm inclined to think not really. Clear editor. I don't have many aerodynamic parts unlocked yet though. I moved the wheels from the tail to the fuel fuselage, and now she takes off like a dream! What is Wario dropping at the end of Super Mario Land 2 and why? If you have a delta wing with a slight AoA and pitch-control elevons at the back, I also find it works well to rotate the elevons back to the pure horizontal. But mostly, the answer is still "because they're fun and educational and you can.". I've found a few body plans to be especially amenable to conversion to VTOL. To start off with, use ANY cockpit you want, this tutorial is going to teach you how to make anything using anything, as long as you follow these directions. Sorry if this is just too basic, it is kind of for beginners, edit: [snipped the stupid thought] i need to stop trying to post when dead tired, I like rules of thumb like these All the info you need without getting bogged down with specifics, Just a quick FYI, you say that CoL is center of thrust and CoT is center of lift; these are the wrong way around. Part of the reason I like the standard canards so much, though, is because they're an all-moving surface, which means you get the maximum possible profile changes with your commands. There's no tutorial in KSP that explains plane design to you and this guide could have taken the lead on that. RCS will get the job done nicely, and looks cool to boot. We look at the principles behind designing a basic jet. Plane - Kerbal Space Program Wiki Also: high proportion of lifting surfaces to non-lifting surfaces. A V/STOL atmospheric craft built for Duna can drop you on any dime, anywhere on the surface. In addition to the tips others have suggested, try locking steering on all your wheels. Additionally if you have any off-center fuel tanks, double check the fuel is drawn from both at the same rate (same priority). Now put on center of mass and center of lift view, and move the delta wings until the center of lift is slightly behind of the center of mass - not in front, otherwise your aircraft will be able to easily flip out of control. They optimize use of oxidizer in SSTOs. In a twin-boom design, you have one hoverjet at the nose, and one in each of the booms. On the other hand, something with a wide wingspan but narrow wings (like the connector Cs) will pitch easily but need more oomph to roll. Hopefully this gets you your first aircraft that can take off and land, which is the biggest hurdle to being able to make KSP aircraft. This item will only be visible to you, admins, and anyone marked as a creator. Building planes is one of the more fun things to do in Kerbal Space Program, and also leads to more science on kerbin and eventually SSTO spaceplanes. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. Note: Your post will require moderator approval before it will be visible. Tutorial: Your First Plane - Kerbal Space Program Wiki The CoT (Center of Thrust) is purple. Body deformation can be caused by heavy parts, many parts connected together, or forces on the plane. Valve Corporation. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Next you need landing gear. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). This item has been removed from the community because it violates Steam Community & Content Guidelines. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Things get ugly!!). TO achieve the easisest way to balance the fuel tanks i never put usable fuel tank in where i cant move ti easily eg. In the crash log, it says that at 00:00:00 there is "Lift-Off!" The CoL should be behind the CoM on a horizontal angle, unless you're building a shuttle. Similar to the fuel pump mods out there now. and i usually find having my dampening a little lower then the spring strength keeps the wheels from "biting". For most small-to-normal-sized craft, you should end up with CoL sitting right at the back of the yellow CoM ball. (However, it must be noted that it is bad practice to use ailerons as elevators since it makes it hard to control the aircraft), The rudder moves the tip of the plane left and right; it is rarely used, since it is hard to put it both up and down due to the possibility of hitting the ground. Also, a good tip: If you use a Panther as a lifting engine, and link the 'Dry/Wet' control to the Stage action group, it allows you to have a lot of control over your lifting thrust (by toggling the Space bar). Otherwise, you can either shift your wings till it's right (though this may crowd them near the back), or you can very slightly rotate the big wings so they're slightly higher near the front of the plane. The hoverjets are housed in the big wing-mounted pods. Remember the, fuel flows from the front in KSP, so you might want to start off with the CoM in front of the CoL. You may need to add several on bigger craft. Finally, it is really difficult to land a HTOL atmospheric craft on Duna because of the thin air: you'll be going really fast and terrain is really bumpy, so there's a huge risk of ending up as a big ball of fire, whereas it's very hard to land a conventional rocket lander precisely,like when you're aiming for your surface base. This makes one engine generate more thrust than the other, exacerbating the turn. and our As with everything in KSP, experiment, experiment, experiment. Your previous content has been restored. All trademarks are property of their respective owners in the US and other countries. Valve Corporation. However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. @davidalangay all of the wings provide lift, and some of them also act as a control surfaces, its pretty self explanitory, Im having a weird glitch, where whenever I make a plane (I even tried copying your design in this guide, to the T, and it broke too) they spawn, and if it's a big plane will always veer off to the left and be completely unable to turn right, and if it's small, then it'll start rocking side to side and flip over. Firstly you're going to want to make a short fuselage. Building planes is one of the more fun things to do in Kerbal Space Program, and also leads to more science on kerbin and eventually SSTO spaceplanes. So this guide is about atmospheric craft designed to fly by makinguse of lift generated by wings, which can take off and land vertically by use of downward-pointing jets or rockets. I might try to write a more advanced guide for spaceplane construction. 19000m. This plane will be able to take off, travel somewhere, perform a crew report, and then land. If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. Build yourself a plane. Also as others have pointed out, keeping the COM/COL/COT alignments proper is essential for aircraft. Making a fuselage. When braking most of the power should be on the rear, or you may see Kerbin up close. Absolutely! This item will only be visible in searches to you, your friends, and admins. Also stock fuel priority is in 1.2, allowing very stable CoM builds. My first VTOL craft was the Bumblebee, and it's still one of my favourites! The juno 8-pack in a mk2 bay is my go-to, plus, a single Engine nacelle will provide enough air for them all and fuel is self-contained, making the design easy to scale for larger craft. This page was last edited on 17 December 2021, at 13:14. principle. The writing is a bit disjointed, because it's been edited and restructured a few times andI'm not a native english speaker. Kerbal Space Program: Propeller Plane Tutorial - YouTube You too!Like - Subscribe - Check out my other tutorials. Now, imagine it forward, it will stall like a REAL plane and will go forward, Front is on the left, and back is on the right. I only very recently got into planes. The ones that are at an angle must be placed at that exact angle, you can't angle them to make them wider. Also: high proportion of lifting surfaces to non-lifting surfaces. You can also use fine controls with the Caps key, or change control surface sensitivity and assigned movements. Then you want to put something called a "Small Circular Intake" on the front of the tank, and a "J-20 Juno" engine on the back of the tank. That should just about do it for basic planes. if that does not work, lower the spring strength until it works properly. One point I would mention is that the more wing area you have relative to your control surfaces, the less angle of attack you can generate. air) that high up. I have not had much success usingonly horizontally oriented intakes - the engines do not have sufficient air flow to generate enough thrust to actually lift the craft. Just sounds like the engines can't get enough air, in KSP high speed also generates air intake so I'm guessing what is happening is that you have the initial speed to get to altitude but the lack of air at altitude is starving the engine resulting in lower speed which further reduces air intake and it cascades until either the engine shuts down or you return to denser atmosphere at a lower altitude. How to Make a Perfect Space Plane - KSP1 Tutorials - Kerbal Space The Panther engine can hold 19,000 steady and oscillates around 20,000. Finally you need to make sure it's all balanced, this means the centre of lift marker needs to be very slightly behind the centre of mass marker. The downside is that it isn't as pretty, but it *does* top out at mach 1.8 with a humble wheesly. Before building planes though, there are some inportant things to know. Good, strong control authority - instead of reducing the pitch control authority, make the plane aerodynamically stable, so that even if you do flip it, it will right itself. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. Wheels need to be touching the ground exactly as they were intended to, you cannot angle them in any direction other then their intended direction when placing them. Control surfaces are your friend. Always look at your aircraft from a 90* angle on the side. 1. When your airspeed is low enough that aerodynamic control is getting sluggish. 2. They sometimes coincide with elevators. I can make a design that's quite good at hovering, landing, and maneuvering around a site like a helicopter, but it'll be crap as an actual aerodynamic plane- as the control surfaces and wing setup are designed for forward flight - and for hovering I want something that has no forward-bias (ever started sliding backwards in a vtol craft designed for otherwise normal forward flight? "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. I decided to look into that two intakes thing, and it turns out to make 11-12 m/s difference at 19,000m with my plane. If you have an account, sign in now to post with your account. Nah, the stabilizer will do it. I have a simple Vtol SSTO that can take off with junos, hit LKO with rapiers, maybe with 100 m/s left on the rocket side, then return to spaceport and have sufficient liquid fuel for vertical landing. You need about 150 m/s for the landing, less than that for take-off. I'm going to strongly suggest using the angle set to 90 degrees + symmetry mode to place landing gears. The parts regarding landing gear placement is especially relevant in 1.1.x. You do need rather a lot of them. Put the big wings right at the back of the plane. They both create a dihedral effect, tending to return you to level through a roll-sideslip interaction. OK, I have a really pedantic question here: Is it even possible to have a practical VTOL craft without using the unlimited fuel cheat? What i do when i build a plane (except the tings others allready mentioned) is playing a lot with the Fuel sliders on fuel tanks in SPH and then moving the tanks and adding removing "balance mass" to the plane untill the COM doesnt move at all relatively to COL, no matter how much fuel i have with tanks. For the vertical engines, do you also need to have some verticalintakes? This guide also applies to STOL (Short Take-Off and Landing) aircraft which do their thing using downward-pointing jets or rockets, because they're pretty much the same thing. That SAS can hold a craft stable doesn't mean it's a stable craft. Kerbin has some biomes that are difficult to reach any other way. Go on, and take the plane capsule which looks like a converted fuel storage device. Plane body deformations can cause the wheels to touch the ground at a slightly different angle. and our These should be in the bottom left next to the display of the cost of the aircraft. Control surfaces near center of mass sometimes get "confused" as to their role and do stupid things. Eventually you either crash, or you reach a high enough speed that SAS wiggling can't cause a significant enough difference in engine speeds. Is it even possible to have a practicalVTOLcraft without using the unlimited fuel cheat? Ok, you will want to start building. The BAK Zephyr, a rocket-powered VTOL craft designed for conducting science missions on Duna. Some general pointers to make more stable aircraft, one is to set your COL just behind your COM, another is that your centre of drag should be as far back as possible - there's no way to visually show this as far as I know but a light but aerodynamically bulky rear to an aircraft generally makes it more stable. Pasted as rich text. May 19, 2013 in KSP1 Tutorials. How do I build a good stable basic plane? SAS sees this and turns the other way, which just causes the same problem in the other direction. It is certainly possible to make VTOLs that can circumnavigate the planet. This reduces the amount of trim you need to apply to get the craft level in flight. Things that work at low altitude don't work so well up high and the plane ends up going up and down while slowly losing speed until it can't maintain altitude anymore. @italian man Great guide, and for people who would like to know the basics of plane building i will be pointing them here. Control your vector primarily with pitch, and your descent rate with throttle.

You might still be able to turn very quickly, but if you don't have enough wing you won't drag your velocity vector with you, which means you force your wings into a stall and bleed energy in a hurry (and can also lose control, depending). By Lift, the canard button), and finally CoT (Center of Thrust, the thruster button) 2. A VTOLaircraftas discussed here is a craft that's designed to fly aerodynamically, using lift produced by lifting surfaces, but take off and land vertically. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. I've never found them to be practical (at least on Kerbin) for anything except short flights around the KSC and flying to the island runway and back. That way you can tuck them away for normal flight, and expose them for hovering. Your airspeed will also fall. The two engines have been mounted every imaginable way with the same result: Over the wings, on the fuselage, on girder segments, on the wingtips, etc. Then go into the move part thing with the "2" key in the editor, remove the degree setting, and then drag them apart manually and position parts with fine tuning that way. First off, make sure you are using the newest version of Kerbal Space Program, and it is NOT pirated, when you buy it, the devs get helped out. While I couldn't accept this one because ultimately it was changing wheel positioning that increased stability enough to elegantly take off, I don't think it's unreasonable to imagine that the oscillations originated or were exacerbated through asymmetric thrust. Connect and share knowledge within a single location that is structured and easy to search. Reddit and its partners use cookies and similar technologies to provide you with a better experience. If it starts tipping in one direction, you're really likely to flip over and crash dramatically, like a tree falling over. Basic Plane Design - KSP Tutorials #9 - YouTube There are lots of ways to make this work, but here are some designs I've used successfully: For rocket-powered hover, use Spark,Aerospike, or Vector (if you really need a lotof hover power). Learn more about Stack Overflow the company, and our products. If the fuel flows from the.

The gear of the craft can also easily be overlooked, but can make the difference between flying masterpiece and soon-to-be-scraps. Love it!! Another possibility to add to the existing answers (it's a bit hard to diagnose without seeing the plane) is that your landing gear might be insufficient for your plane's mass.
