What is this brick with a round back and a stud on the side used for? [Stock] Brikoleur's Guide to VTOL Aircraft, fuel and trying to add more fuel means you need. Pasted as rich text. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). In that vein I drag optimized the Karmilla, and added science parts. Paint a picture in that little head of yours, imagine that the Mass was in the back, when you stall it, it will ALWAYS fall backwards and. I think it might be so small it starts with floating-point rounding errors; it's exponential and compounds every frame. if that does not work, lower the spring strength until it works properly. 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. Next you need landing gear. Nothing bad will happen. This item has been removed from the community because it violates Steam Community & Content Guidelines. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Note: Your post will require moderator approval before it will be visible. The main challenge for hover control is to keep the craft horizontal. If you have an account, sign in now to post with your account. As with everything in KSP, experiment, experiment, experiment. In 5e D&D and Grim Hollow, how does the Specter transformation affect a human PC in regards to the 'undead' characteristics and spells? In the crash log, it says that at 00:00:00 there is "Lift-Off!" Another pointer is to make your wings larger with the same amount of control surface. It is entirely powered by Terriers. 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. You need to sign in or create an account to do that. More air is better. Also stock fuel priority is in 1.2, allowing very stable CoM builds. People put waaaaaaaaay too many control surfaces on things from a lot of the screenshots I see. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. If you have a perturbation that gives your left engine a tiny bit more thrust, you will turn slightly right. An aircraft without control surfaces is like a rocket without RCS or reaction wheels - it will hardly turn and will be equally hard to control (perhaps even impossible!). Your main lift, though, should always be as closely centered on your CoM as you can manage. 1) Before adding your pitch control surfaces, move the main wing to make sure that CoM is very very slightly in front of CoL, or exactly on the same spot (if you want more maneuverability). Congratulations! principle. The more intakes added, the higher a plane can go before a flame-out, which makes multiple intakes a must on SSTO spaceplanes. Try reducing control authority (or even generally amount) of control surfaces - rudder, ailerons, the front wheel (maybe even make it a fixed one). front, then it automatically disbalances the weight moving the weight to the back. Your very own tutorial.). Also there it's important to place small landing gear after setting up CoL to CoM relation since it's mass is calculated in CoM in SPH/VAB but not counted in flight. If you forget to put an air intake on your airplane, don't worry! You can pick the main cockpit and rotate the whole craft with it in SPH to see where your CoL will drift. Adding a vertical intake helps. 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. ps: use caps lock(fine control) to reduce the amount you're actually moving the control surfaces. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. Ok, you will want to start building. They both create a dihedral effect, tending to return you to level through a roll-sideslip interaction. (KSP 1.9.1) Subscribe - http://www.youtube.com/c/MikeAben?sub-confirmation=1 Patreon - https://. Better still, three screenshots showing side, top, and rear views. After the drag was sorted out, it wasn't very hard to create a dockable SSTO version. 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. Do you have a picture? Interesting design!! That is something I am really looking forward to. The BAK Drakula. A Screenshot of Kerbal Space Program. With a decent lever arm to work with you can be both perfectly stable in level flight and very agile in pitch and yaw controls. There are multiple ways to place them: Ailerons control the roll of the aircraft, and are (almost) always placed on the wings, as far out as possible and as centered (compared to the center of mass) as could be. Valentina would really appreciate if I could get my airplane off the ground, but it keeps exploding on the runway by the exact same failure mode: The plane veers to one side or another, either I or SAS correct it, which starts a left/right wobble, which builds until one of the wings hits pavement, at which point the craft quickly brings Valentina to her untimely end. That should just about do it for basic planes. Usually, having one or two medium-sized intakes will more than suffice on a regular plane. And start small. This page was last edited on 19 February 2020, at 07:08. 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. Nah, the stabilizer will do it. So the ones that go straight up and down can only be straight up and down, no angling left, right, backwards or forwards such as when you place the little wheel on the angled body of the cockpit part. All trademarks are property of their respective owners in the US and other countries. 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). When braking most of the power should be on the rear, or you may see Kerbin up close. For what it's worth - watching 1.2 pre-release streams, the upcoming changes to SAS are profound. 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. Thanks for any answers! You would need a lot of orbits at 69 km to come down into the ground. You can post now and register later. Display as a link instead, Edit: After reading it again, it just seems to have a bit too many errors. Guest, Except for the parts regarding drag and number of intakes, everything else is still very valid. You can horse hundreds of tonnes, up and down both, with the standard canard pieces. You want to keep the CoL slightly behind the CoM, but not too much to not create torque. They're obviously bigger and less efficient than conventional landers again because of the extra engines you're hauling; the advantage is being able to land them exactly where you want, while having the capability to explore the planet with atmospheric flight. For most small-to-normal-sized craft, you should end up with CoL sitting right at the back of the yellow CoM ball. If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. New comments cannot be posted and votes cannot be cast. For more information, please see our The downside is that it isn't as pretty, but it *does* top out at mach 1.8 with a humble wheesly. If his problem is the plane doing backflips at a touch of 's', I wouldn't go with 'slightly'. Connect and share knowledge within a single location that is structured and easy to search. Your CoT vector will disappear. Your airspeed will also fall. My Hats off to Brikoleur, as a fellow VTOL/general spaceplane [stock] enthusiast, your tips were easy to read and right on the money! Set up your control scheme: one action group for toggling the hover jets, another action group for toggling the main jets, plus yet another one to toggle the hover jet bays, if you're using them (as you should). The first challenge you're likely to hit is choice of hoverjet. Arqade is a question and answer site for passionate videogamers on all platforms. The buttons show you CoM (Center of Mass, The anvil button), CoL (Center of, Lift, the canard button), and finally CoT (Center of Thrust, the thruster button). This should reduce ground control authority and make oscillations less powerful. I don't have that other stuff yet. And above all: have fun! 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.

Level:Intermediate/Advanced:You need to be able to slap together a plane that flies reasonably well before attempting a VTOL.Background reading:Start with the fantastic Basic Aircraft Design tutorial in this very forum.Craft used to illustrate this tutorial: VTOL stands for "Vertical Take-Off and Landing." 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. One challenge I've run into for myself with more elegant VTOL SSTOs is low-speed-hover controllability; beyond using brute-force RCS or SAS. Any plane needs speed - so you need thrust (usually). Why did DOS-based Windows require HIMEM.SYS to boot? 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. Always look at your aircraft from a 90* angle on the side. You've just unlocked "Aviation" tech, you have a bunch of contracts that require you to stay at low altitude, and you want to build your first plane? Now stick a jet engine on the back, and don't forget to put an air intake or other air-sucking device (you can find them in aerodynamics) on the airplane. They'll still happen but you'll have more time to get off the ground. This item will only be visible in searches to you, your friends, and admins. 2) Then add the pitch control surfaces. The solution is to house the hoverjets in a cargo bay of some kind, with the doors opening downwards. How to force Unity Editor/TestRunner to run at full speed when in background? To land a VTOL aircraft, approach the landing zone as you would with a regular HTOL craft, until on final approach. If the fuel flows from the. All rights reserved. Is there any way to reliably fix this? 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. If additionally you can give it a controlled tilt and hold it there, then it'll start accelerating in that direction, like a helicopter. hope you and others find that useful in the future! The CoL should be in the center or just behind the CoM. For comparison the speed of a stable Low Kerbin Orbit at 70 km (outside the atmosphere . They sometimes coincide with elevators. From your description of your plane I would check the following: You seem to have done a lot of things right. We're also not discussing helicopters here, because stock kerbals have not invented the propeller, and stock propellers are a whole big topic of their own. Please see the. and our All you need to do is add landing gear (one right before the cockpit, and two on the tips or middle of the wings), and you're done! How do I build a good stable basic plane? In this tutorial we cover the basics of building and flying a jet in Kerbal Space Program. Subscribe - http://www.youtube.com/c/MikeAben?sub-confirmation=. rev2023.5.1.43405. Such a simple and basic tip, but so unknown throughout KSP. 2. You can either go with four "LY-O1 Fixed" or a tricycle of two LY-01 near the back and one "LY-05 Steerable" at the front; either is fine for now. Intriguingly, there is one thing I've found that does prevent the wobble from starting, and that is to use a single engine mounted directly on the back of the fuselage, which prevents using a tail and is ultimately a fairly significant restriction to build around. In principle it's simple just place your fuel symmetrically around the dry CoM, and centre your vertical thrust vector on it but how? For the CoM / CoL relationship to get a stable-yet-maneuverable craft, I'd recommend doing the tweaks in two stages. Which was the first Sci-Fi story to predict obnoxious "robo calls"? Sparks will fit in Mk 1 utility bays, the bigger ones will fit in the bigger cargo bays (Mk 2, 2.5m utility bay, Mk 3). You're one of the few I've read that recognized the potential of Junos in vtol vs the more popular panthers or using rotating clamp-o-tron assemblies- bigger engines have the huge design downside of shifting COM above fuselage longitudinal axis, which makes rocket placement difficult for SSTOs. Rasterpropmonitor for Kerbal Space Program, How can I cheat docking in Kerbal Space Program. Reaction wheels will balance smaller craft just fine, but are probably insufficient for bigger ones. If you have an account, sign in now to post with your account. 2023 Take-Two Interactive Software, Inc. Once you got a hang of these, try bigger stuff. 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. Aim to get your speed below 50m/s, and have plenty of water ahead of you; keep the plane level, and pitch up to shed velocity. First off, make whatever you want, just, start off making sense. Espaol - Latinoamrica (Spanish - Latin America). However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using. 2. The absurdly big wing and control surfaces make it highly economical for high-altitude supercruising. But it should most definitely be in front of it, and preferably NEVER move behind it, even with empty fuel tanks. 4. I actually like canard layouts, but I'm going to endorse this post because it's a simple, easy way to do it. Simply changing the intakes made it fly completely out of control and impossible to land. Unfortunately, with only these basic parts, landing on the runway won't be easy; a viable alternative is to throttle down to nothing, then belly-flop in the ocean. Hovering is expensive but you don't really need all that many seconds of hover either for take-off or for landing. Making a fuselage. Powered by Invision Community. the vertical stabilizer only handles yaw? 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. However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using. When you're close to it, INCREASE THROTTLE until your rate of descent nears zero. The further along in plane-building experience and flying you go, the more designing them becomes more natural(and the more this guide becomes irrelevant :( ). Elevators are usually places in the front or back of an aircraft, and their function, as the name implies, is to change the pitch of the nose up and down. Then I'd go with moving it towards more maneuvrable by moving CoL towards CoM. (Yes, you personally, you lucky thing! You may need to add several on bigger craft. For the vertical engines, do you also need to have some verticalintakes? the front should be close to double the rear gears strength) And Good Guide! Start with simplest, easiest planes you can and then increase complexity observing and mitigating problems as they arise. Clear editor. First, @TheEnvironmentalist There is one more method I'm sure would work in your case, although I didn't write about it because I think it's, Hahaha absolutely right, but distinctly less satisfying. +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." 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. In vanilla KSP, wings have a predefined lift factor. For all your gaming related, space exploration needs. Smaller wings on the cockpit can be good. I'm going to strongly suggest using the angle set to 90 degrees + symmetry mode to place landing gears. and i usually find having my dampening a little lower then the spring strength keeps the wheels from "biting". i dont know what kind of range youre looking for but i would make a significantly smaller plane. About the landing gear, the best way to stop the weird self steering issue is to increase the spring and damper strength. My question is really about controllability. It's said that takeoffs are optional but landings are mandatory. What version is the Kerbal Space Program demo? 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. You arent doing anything wrong. Roll is the main way to change direction in flight, and best way to crash the plane on the ground. 2023 Take-Two Interactive Software, Inc. Flying planes will be much simpler, with much reduced cross-control issues. This thread is quite old. Here is your convenient solution to this problem! Air-breathing hoverjetsneedintakes. The CoL (Center of Lift) is a blue ball. The BAK Cyclone hard at work on Duna. When off the ground at a sufficient altitude to clear obstacles, main jets ON, When at sufficient speed for aerodynamic flight, hoverjets OFF, pods CLOSED, gear UP. You can "smooth" controls by toggling capslock on your keyboard, the control indicators in the bottom left will turn blue from orange and they are instance dependant (if you revert your flight you'll have to toggle capslock again). LTTP but anyway: the question is, practical for what? You know you don't have enough if you're getting engine flame-outs on take-off or, worse, landing. Any insights? Whiplash is the engine you would want to use on a plane meant to go 20km. - SF. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). Sometimes though, planes need to do more complex jobs, like flying farther or making it to space, so I am planning on adding another guide to explain how to make and what to consider in an SSTO spaceplane. Mount your rear wheels out on the wings for better stability. To fly a VTOL craft, you need to be able to perform the following actions, which must be bound to a an action group: If you have full RCS control, you will additionally need control for that, and if your hoverjets are inside pods, you will want a control for toggling them too. Interesting, though even being exponential theres a chance it starts out so small it takes longer than a takeoff to reach noticeable levels. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. Put the big wings right at the back of the plane. How to keep an airplane stable on the runway in Kerbal Space Program? For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. User without create permission can create a custom object from Managed package using Custom Rest API. Also: high proportion of lifting surfaces to non-lifting surfaces. I didn't try for 20000m as it probably wouldn't do well. 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). 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 should have something called an "Elevon 1"; this will be the moving part for your wings. Upload or insert images from URL. I'm finding it quite surprising you didn't manage to get the plane to fly yet. I've covered all my bases, as far as I can tell: It seems if I turn off SAS, I can prevent the oscillation from starting as it's initiated by some control input, whether from me or SAS, but then the plane veers off the runway until it hits something. Thank you for posting this. 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. The BAK Zephyr, a rocket-powered VTOL craft designed for conducting science missions on Duna. So, if you're having this problem then. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Use Pilot Assistant - it's SAS is meant for aircraft rather than general ( read: rocket ) use. Now right click each elevon and the tail fin and set what movement each controls; the ones on the large wings control roll only, the ones on the back wings control pitch only, and the tail fin controls yaw only. What are the arguments for/against anonymous authorship of the Gospels. Your plane is almost finished. Clear editor. This is my current best hi alt plane. The ones that are at an angle must be placed at that exact angle, you can't angle them to make them wider. You can post now and register later. Embedded hyperlinks in a thesis or research paper. It is usually placed back because it can be placed further back than it is possible in the front (if it is placed in the front, it can obstruct the view of the pilot, which is undesired) as well as making the plane unstable (by the same effect that you would get if the center of lift (horizontal lifting surfaces) were in front of the center of mass, but with vertical surfaces). So if you're getting those flame-outs, add more intakes until you don't get them anymore. Right click on the control surfaces and knock down the control authority of each item. I moved the wheels from the tail to the fuel fuselage, and now she takes off like a dream! Note: Your post will require moderator approval before it will be visible. Check out Mike from Merrimack, New Hampshire as he explains to filmmaker Rod Webber what' NEVER go forwards, causing the aircraft to crash itself. 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. Designing a First Plane - KSP Beginner's Tutorial - YouTube Cookie Notice 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). - but they were talking about having two intakes/engine. 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. Why don't we use the 7805 for car phone chargers? Intakes are your friend when you use liquid fuel. It is certainly possible to make VTOLs that can circumnavigate the planet. Kerbal Space Program: Propeller Plane Tutorial - YouTube Can't remember where I saw/read about it - Scott Manley maybe? 2023 Take-Two Interactive Software, Inc. And start small. Enable mirror symmetry to save yourself some alignment effort. How to keep an airplane stable on the runway in Kerbal Space - Arqade You want an elevon on each set of wings. Aircraft are surprisingly difficult beasts to build and control, building a stable, flyable aircraft is surprising complicated, so this is the first of a num. 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. Things get ugly!!). The Kerbal Space Program subreddit. Another way to manage this is to mount your wings above your CoM. Is there such a thing as "right to be heard" by the authorities? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Espaol - Latinoamrica (Spanish - Latin America), https://steamcommunity.com/sharedfiles/filedetails/?id=1933948095, https://steamcommunity.com/sharedfiles/filedetails/?id=1933948668, https://steamcommunity.com/sharedfiles/filedetails/?id=1934517923, https://steamcommunity.com/sharedfiles/filedetails/?id=1335577943, https://steamcommunity.com/sharedfiles/filedetails/?id=1640213502, https://steamcommunity.com/sharedfiles/filedetails/?id=1640214586, https://steamcommunity.com/sharedfiles/filedetails/?id=1937826505, https://steamcommunity.com/sharedfiles/filedetails/?id=1937931692. Additionally if you have any off-center fuel tanks, double check the fuel is drawn from both at the same rate (same priority). I've found that all my runway wiggling planes are caused by the wheels. First thing you're going to want to do in the SPH is turn on your centre of mass indicator (this is the point that the plane will rotate around when rolling, pitching, or yawing) and your centre of lift indicator (the Aerodynamic Overlay). Please consider starting a new thread rather than reviving this one. 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. It may be too far forward, especially if the tail is too small relative to the plane's wings. Also stock fuel priority is in 1.2, allowing very stable CoM builds. If it doesn't, he can just make the stabilizer bigger; instead of turning down control authority, just add more fixed wing. A Mk1 Cockpit, two Mk 1 Liquid Fuel Tanks, and then cap the back with a round nose cone (use the A/D keys to rotate it as necessary). 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.
