(This is key to making a simple functional plane in KSP.) Also stock fuel priority is in 1.2, allowing very stable CoM builds. So if you're getting those flame-outs, add more intakes until you don't get them anymore. Ill edit this sometime this week. So thanks for the pointers - I'll take a look (and try to cure my prejudice re canards). You should talk about the rocket engine's dV (approx., since not all users use Mechjeb or any other mod capable of showing dV for a given engine and tank). Hi @Brikoleur, nice work! 2023 Take-Two Interactive Software, Inc. They sometimes coincide with ailerons on some, more space-economical, aircraft. If you have a perturbation that gives your left engine a tiny bit more thrust, you will turn slightly right. 2) Then add the pitch control surfaces. Not so with VTOLs: if the CoM shifts, you're not going to be able to land vertically anymore. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. Lift, the canard button), and finally CoT (Center of Thrust, the thruster button) 2. A slight "inwards" tilt on your wings (5 degrees or less) will improve stability hugely and will cause your plane to slowly correct itself in flight, also if you're using large control surfaces at high speeds then the result is obvious. 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!). Getting a plane of the round isn't that hard. Do you by chance know how much the thrust varies with these small velocity perturbations? Also, make sure you read this slowly, some of this stuff may be confusing, but, if you read carefully, I will help you out with what everything means. 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). Valve Corporation. All trademarks are property of their respective owners in the US and other countries. I don't have that other stuff yet. Junos, Panthers, and Wheesleys are all fairly efficient at low altitude and low speed - when you said 'guzzle' i screwed up my face because when I think guzzle I think rapiers and whiplash's putting out 300 kN and just gorging on fuel. Whiplash is the engine you would want to use on a plane meant to go 20km. Whether VTOL craft arepracticalor efficientcompared to other solutions is a different matter -- and to be perfectly honest, I'm inclined to think not really. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Basic_Plane_Design&oldid=97453, In the front of the plane - In this position, the control surfaces are also known as , In the back of the plane, on the tail - The most usual position; usually, close to the rudder. Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? In principle it's simple just place your fuel symmetrically around the dry CoM, and centre your vertical thrust vector on it but how? high altitude flight :: Kerbal Space Program General Discussions Can't remember where I saw/read about it - Scott Manley maybe? Absolutely! 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. Before building planes though, there are some inportant things to know. Flying planes will be much simpler, with much reduced cross-control issues. I haven't found a sure-fire solution to this, but I think I know what causes it. And there's the ever awesome 101 from @keptin. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. 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. Powered by Invision Community. Reaction wheels will balance smaller craft just fine, but are probably insufficient for bigger ones. Next question? I'm trying to build a high altitude plane and have found out that the rules are different. Right click on the control surfaces and knock down the control authority of each item. Plane body deformations can cause the wheels to touch the ground at a slightly different angle. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. People put waaaaaaaaay too many control surfaces on things from a lot of the screenshots I see. About the landing gear, the best way to stop the weird self steering issue is to increase the spring and damper strength. Even though it just spawned. I only very recently got into planes. The gear of the craft can also easily be overlooked, but can make the difference between flying masterpiece and soon-to-be-scraps. 2. This one is balanced with reaction wheels. Also stock fuel priority is in 1.2, allowing very stable CoM builds. 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. For all your gaming related, space exploration needs. You cannot paste images directly. Or about the same speed but 1000 m higher. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. In that vein I drag optimized the Karmilla, and added science parts. 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. Before building planes though, there are some inportant things to know. rev2023.5.1.43405. I was hoping that the new intakes would give it the added altitude. 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. ps: use caps lock(fine control) to reduce the amount you're actually moving the control surfaces. This page was last edited on 19 February 2020, at 07:08. Reddit and its partners use cookies and similar technologies to provide you with a better experience. But mostly, the answer is still "because they're fun and educational and you can.". This would certainly have to be revised once Breaking Ground drops, those parts are extremely relevant for VTOL. what do you mean by "wheels are mounted with angle snapping"? By 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. If you believe your item has been removed by mistake, please contact, This item is incompatible with Kerbal Space Program. This should reduce ground control authority and make oscillations less powerful. But it flies horribly, it's all over the place even with SAS on it doesn't fly even remotely stable. Upload or insert images from URL. Upload or insert images from URL. Your choice of RCS jet is the Place-Anywhere or the Vernor. Also: high proportion of lifting surfaces to non-lifting surfaces. if that does not work, lower the spring strength until it works properly. Start with simplest, easiest planes you can and then increase complexity observing and mitigating problems as they arise. The solution is to house the hoverjets in a cargo bay of some kind, with the doors opening downwards. 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). 3. Clear editor. You want to keep the CoL slightly behind the CoM, but not too much to not create torque. Valve Corporation. 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. Also, layout matters: aircraft with a wing that runs along the length of the craft, but with a narrow wingspan (like the Mk2 fuselages or wing strakes, and to a lesser extend swept or delta wings) will take more effort to pitch over but will roll very, very easily. E.g. Your plane is almost finished. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 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). Two MacBook Pro with same model number (A1286) but different year. At this point you'll probably need to go back to the plane design you started with, because air intakes are dry mass and will shift the CoM as you add them. How to Make a Perfect Space Plane - KSP1 Tutorials - Kerbal Space Then at the top, we'll put one tail fin, centred on the end of the fuselage. Would I be better unlocking more parts and leaving this contract for later? 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. Which reverse polarity protection is better and why? However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using. I really hope that this will help you, if you would like more tutorials, click these links: Hello, today I will be showing you how to make an absolutely perfect space plane! It only takes a minute to sign up. Body deformation can be caused by heavy parts, many parts connected together, or forces on the plane. They both create a dihedral effect, tending to return you to level through a roll-sideslip interaction. This thread is quite old. You arent doing anything wrong. I wrote a post that covers similar topics. In 5e D&D and Grim Hollow, how does the Specter transformation affect a human PC in regards to the 'undead' characteristics and spells? Control surfaces near center of mass sometimes get "confused" as to their role and do stupid things. also, you state that a stabilizer (you called it a tail) isn't necessary, and although that's true, it's worth noting that a stabilizer is vital in preventing, and recovering, from flat spins, which can be extremely dangerous. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! 2023 Take-Two Interactive Software, Inc.

Designing a First Plane - KSP Beginner's Tutorial - YouTube Learn more about Stack Overflow the company, and our products. November 1, 2018 in KSP1 Tutorials. Congratulations! They have in common that it's easy to tweak the balance by moving things around, rather than having to add or remove pieces. After the drag was sorted out, it wasn't very hard to create a dockable SSTO version. You would need to get down into the 37k-45k zone to aerobrake enough to come down in one orbit. 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). Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. Hit the launch button and watch your magnificent bird fly! Starting from something with MK3 hull without experience in MK1 will be an uphill battle. For the CoM / CoL relationship to get a stable-yet-maneuverable craft, I'd recommend doing the tweaks in two stages. The Kerbal Space Program subreddit. 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. Edit: After reading it again, it just seems to have a bit too many errors. How do I make aircraft stable & smooth to control? QAnon follower explains that Trump is the shadow President and James Any plane needs speed - so you need thrust (usually). If you (or SAS) turns even just a little, the engine opposite your turn will have a higher velocity than the one towards your turn. Yes! Remember the, fuel flows from the front in KSP, so you might want to start off with the CoM in front of the CoL. One of the most finicky problems with VTOL craft is managing centre of mass. That is something I am really looking forward to. How to keep an airplane stable on the runway in Kerbal Space - Arqade The CoG shouldn't be TOO far in front of the CoL, though. No, the intakes don't have to be vertical. Have fun with your S/VTOL craft and don't forget there are more ways to do them as well, including helicopter-like things that don't fly aerodynamically at all. 100% is fine for doing a pure Pilot Assisted flight but for keyboard piloting it's too much. 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. Now to try it on one of those high altitude missions. Your plane will be slow and have limited range, or you'll have to make it a lot bigger to brute-force your way around that limitation. At low speeds, this difference can be significant. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Throttle up to full, activate SAS, stage to start the engine (you'll only have one stage here), and start rolling (or sliding) down the runway! I've been playing around with aircraft over the past couple days, only to find that no matter how low I set the pitch authority, they tumble and crash at the slightest hold of the "S" key. This guide will show how to make simple-ish planes and other aerodynamic tips. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). How do I build a good stable basic plane? Things get ugly!!). It also depends on whether you're using FAR or another aerodynamic rewrite mod that would change the way your aircraft behave. Here is your convenient solution to this problem! You may be correct and that 3 engine plane is a lemon. (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. Connect and share knowledge within a single location that is structured and easy to search. Guest, https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. Rockets are much less efficient than air-breathers, so it needs to be much bigger than a Kerbin-bound craft performing the same mission! 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. SAS sees this and turns the other way, which just causes the same problem in the other direction. So basic, anyone can do it. 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. Steam Community :: Guide :: Basic Planes Guide Similar to the fuel pump mods out there now. @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 cheesy and wouldn't solve the root problem. For more information, please see our and i usually find having my dampening a little lower then the spring strength keeps the wheels from "biting". Note: Your post will require moderator approval before it will be visible. Pasted as rich text. All rights reserved. I haven't encountered oscillations like that in an airplane but I have encountered them aplenty in case of lightweight probes that have too strong control authority - too good RCS or reaction wheels, so I suspect the source here is the same. Can you check what happens if you increase the tail size to pull the center of drag back? In the crash log, it says that at 00:00:00 there is "Lift-Off!" This plane will be able to take off, travel somewhere, perform a crew report, and then land. When you're close to it, INCREASE THROTTLE until your rate of descent nears zero. They can be placed on wings. Their hoverjets just have a TWR of less than 1.0. A Screenshot of Kerbal Space Program. There are a few missions for which a VTOL aircraft is ideal. If additionally you can give it a controlled tilt and hold it there, then it'll start accelerating in that direction, like a helicopter. 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. 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). zombie2u, Then this tutorial is for you. For your first flight, it may be easiest to ignore yaw altogether and just maneuver by rolling slightly and pitching. The second one is likely to be aerodynamics if you just stick on some downward-pointing jets, you will find that they produce a lot of drag, which is going to be really inefficient. Haha I think Ive perfected an aestheticallyclean turbine jet VTOL USAF F-35b Lightning II2020 https://imgur.com/gallery/918HyM4 https://imgur.com/gallery/f0NDJxR. The CoL should be behind the CoM on a horizontal angle, unless you're building a shuttle. It is certainly possible to make VTOLs that can circumnavigate the planet. This can be most helpful when transitioning to or from level flight. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. The BAK Drakula. Build yourself a plane. 2023 Take-Two Interactive Software, Inc. All other versions are slower and lower and unstable in turns. Nah, the stabilizer will do it. Any insights? The BAK Zephyr, a rocket-powered VTOL craft designed for conducting science missions on Duna. 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? In fact, nothing will happen at all, and that's probably bad, so put an air intake on your plane anyway. Cookie Notice 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. 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. You need enough intakes to keep them fed. User without create permission can create a custom object from Managed package using Custom Rest API. 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). In other words classic tripod. I would really suggest this guide for beginners trying to get into the world of planes in Kerbal Space Program. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Such a simple and basic tip, but so unknown throughout KSP. I moved the wheels from the tail to the fuel fuselage, and now she takes off like a dream! If you have more than one engine, you can get asymmetric thrust at low speeds. 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. So yes, it most definitely is possible. Thanks for any answers! The BAK Karmilla. The first challenge you're likely to hit is choice of hoverjet. (if the front gear is the same ditance from the CoM as the 2 rear gears. LTTP again (KSP on hiatus for a bit), but here's an answer anyway. Smaller wings on the cockpit can be good. A twin-pod design is similar to a twin-boom, except that it has a conventional tail extending from the fuselage. You too!Like - Subscribe - Check out my other tutorials. Imagine that first plane but with the bubble cockpit and the old style round intakes. Use Pilot Assistant - it's SAS is meant for aircraft rather than general ( read: rocket ) use. Set the thrust limiter on your main engines to zero. You would need a lot of orbits at 69 km to come down into the ground. Set the thrust limiter on your main engines to zero. 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. 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. Your link has been automatically embedded. 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. 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. Plane - Kerbal Space Program Wiki +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." I actually like canard layouts, but I'm going to endorse this post because it's a simple, easy way to do it. 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. Can you check what happens if you swap in larger gear? 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. These tend to handle best. Arqade is a question and answer site for passionate videogamers on all platforms. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. 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. My question is really about controllability. This ensures that your aircraft will go up once it achieves a high enough speed, and also helps with placing ailerons. And start small. Switch on the CoM and CoT overlays. But be careful and don't crash it! This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. Your very own tutorial.). Touch down, CUT throttle, CUT engines, BRAKES ON. The CoM (Center of Mass) is a yellow ball on your spacecraft when you enable it in the SPH. the vertical stabilizer only handles yaw? [Stock] Brikoleur's Guide to VTOL Aircraft, fuel and trying to add more fuel means you need. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Note: Your post will require moderator approval before it will be visible. You can pick the main cockpit and rotate the whole craft with it in SPH to see where your CoL will drift. For what it's worth - watching 1.2 pre-release streams, the upcoming changes to SAS are profound. Build yourself a plane. You need to sign in or create an account to do that. To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. If you forget to put an air intake on your airplane, don't worry! Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. CoL (Blue ball) position relative to CoM (Yellow ball) is very important. And above all: have fun! This is always my strategy for building planes (although sometimes things go horribly wrong for a different reason.)
