I moved the wheels from the tail to the fuel fuselage, and now she takes off like a dream! Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. (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. If it starts tipping in one direction, you're really likely to flip over and crash dramatically, like a tree falling over. This page was last edited on 19 February 2020, at 07:08. Yes! 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. Also, lift is usually placed in the middle-to-back of the wing, depending on the shape. 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=. one last thing to verify: look from the side, observe where your center of mass is, then how the control surfaces are located relative to it and if the way they react to your controls makes sense (just try to pull up, down, or roll, on the runway without even starting the engine or disengaging brakes and watch which way the control surfaces move). What version is the Kerbal Space Program demo? You can post now and register later. All trademarks are property of their respective owners in the US and other countries. As you reach 100m/s, hold S to pull the stick back, and you should be in the air! Thank you for posting this. rev2023.5.1.43405. Does the order of validations and MAC with clear text matter? The first challenge you're likely to hit is choice of hoverjet. If you forget to put an air intake on your airplane, don't worry! Have you set your control surfaces to only respond to appropriate controls? If you believe your item has been removed by mistake, please contact, This item is incompatible with Kerbal Space Program. Now stick a jet engine on the back, and don't forget to put an . Additionally if you have any off-center fuel tanks, double check the fuel is drawn from both at the same rate (same priority). This reduces the amount of trim you need to apply to get the craft level in flight. 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. Making a fuselage. @TheEnvironmentalist No clue, but it doesn't need to be much because it's a feedback loop. Your main lift, though, should always be as closely centered on your CoM as you can manage. 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. I have some really good tips and tricks to add to your tutorial,but Im on my phone at the moment. SAS sees this and turns the other way, which just causes the same problem in the other direction. That is something I am really looking forward to. Simply changing the intakes made it fly completely out of control and impossible to land. I've found a few body plans to be especially amenable to conversion to VTOL. 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. Another pointer is to make your wings larger with the same amount of control surface. You cannot paste images directly. Move them back and fill them with fuel or weigh them down with control surfaces. This would certainly have to be revised once Breaking Ground drops, those parts are extremely relevant for VTOL. You do need rather a lot of them. 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. http://kerbalspaceprogram.com. 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). They sometimes coincide with ailerons on some, more space-economical, aircraft. Kerbin has some biomes that are difficult to reach any other way. The BAK Cyclone hard at work on Duna. Learn more about Stack Overflow the company, and our products. Are there any canonical examples of the Prime Directive being broken that aren't shown on screen? Not so with VTOLs: if the CoM shifts, you're not going to be able to land vertically anymore. The BAK Cyclone, delivering a station module to Duna. You can horse hundreds of tonnes, up and down both, with the standard canard pieces. The ones that are at an angle must be placed at that exact angle, you can't angle them to make them wider. 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. I've spent some time scouring the internet for ways of solving this problem, and found a number of pieces of advice on preventing wobble and improving planes in general, some of which made it into the above list, but Valentina's still dying, and I'm tired of Kerbal funerals. Clear editor. Smaller wings on the cockpit can be good. You can pick the main cockpit and rotate the whole craft with it in SPH to see where your CoL will drift. Your CoT vector will disappear. 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. If the CoM is in the back, then it will ALWAYS not be able to get out of a stall, flatspin all the time, and will be an all around horrible plane. Paste as plain text instead, Now for the engines. Rasterpropmonitor for Kerbal Space Program, How can I cheat docking in Kerbal Space Program. I don't have that other stuff yet. So, if you're having this problem then. if you are making a plane that's going to be pulling stunts or making extreme maneuvers, a stabilizer is pretty important. Do you by chance know how much the thrust varies with these small velocity perturbations? (KSP 1.9.1) Subscribe - http://www.youtube.com/c/MikeAben?sub-confirmation=1 Patreon - https://. Flight records. I might try to write a more advanced guide for spaceplane construction. Paste as plain text instead, 2. You will need more jets at the nose and tail than on the wingtips, as there will be more forces on pitch when transitioning to or from level flight. 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. Your, Add enough downward-pointing jets to lift the plane, as symmetrically as you can around the, Adjust the thrust limiter on the fore (or aft) hoverjets until the thrust vector lines up with the. Cookie Notice 1. 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. Hit the launch button and watch your magnificent bird fly! If you have an account, sign in now to post with your account. A Screenshot of Kerbal Space Program. The best answers are voted up and rise to the top, Not the answer you're looking for? 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. And start small. Terriers will also work on Duna. 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. 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. Hint:The engine pre-cooler and engine nacelle are fantastic air intakes, and they can be mounted in-line or combined with other elements. May 19, 2013 in KSP1 Tutorials. Upload or insert images from URL. Set the thrust limiter on your main engines to zero. Also: high proportion of lifting surfaces to non-lifting surfaces. Build yourself a plane. All other versions are slower and lower and unstable in turns. And there's the ever awesome 101 from @keptin. Body deformation can be caused by heavy parts, many parts connected together, or forces on the plane. You want an elevon on each set of wings. That SAS can hold a craft stable doesn't mean it's a stable craft. The BAK Drakula. 2023 Take-Two Interactive Software, Inc. 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? For more information, please see our Remember the, fuel flows from the front in KSP, so you might want to start off with the CoM in front of the CoL. Standard KSP airplane-stability request: post a screenshot of your airplane in the SPH, with the center-of-mass, center-of-lift, and center-of thrust markers shown. Plane body deformations can cause the wheels to touch the ground at a slightly different angle. 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. 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! November 1, 2018 in KSP1 Tutorials. This happens in two instances; initial placement and plane body deformation. The solution is to house the hoverjets in a cargo bay of some kind, with the doors opening downwards. 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. Build yourself a plane. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. It is entirely powered by Terriers. You cannot paste images directly. 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. Pasted as rich text. And start small. 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. Try not to make your first airplanes longer than 3 MK1 fuselages. 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. People put waaaaaaaaay too many control surfaces on things from a lot of the screenshots I see. This makes one engine generate more thrust than the other, exacerbating the turn. Any insights? 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. @italian man Great guide, and for people who would like to know the basics of plane building i will be pointing them here. I've always found that best way to not crash on the take off is to take off. You need enough intakes to keep them fed. Such a simple and basic tip, but so unknown throughout KSP. You too!Like - Subscribe - Check out my other tutorials. When braking most of the power should be on the rear, or you may see Kerbin up close. Can you check what happens if you increase the tail size to pull the center of drag back? If the fuel flows from the. Firstly you're going to want to make a short fuselage. 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. 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. Can't remember where I saw/read about it - Scott Manley maybe? Control surfaces near center of mass sometimes get "confused" as to their role and do stupid things. Lift, the canard button), and finally CoT (Center of Thrust, the thruster button) 2. Note the landing area markers. For the vertical engines, do you also need to have some verticalintakes? Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 3. Any plane needs speed - so you need thrust (usually). You should have something called an "Elevon 1"; this will be the moving part for your wings. LTTP but anyway: the question is, practical for what? But mostly, the answer is still "because they're fun and educational and you can.". and i usually find having my dampening a little lower then the spring strength keeps the wheels from "biting". Roll is the main way to change direction in flight, and best way to crash the plane on the ground. One of the most finicky problems with VTOL craft is managing centre of mass. This should reduce ground control authority and make oscillations less powerful. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. We look at the principles behind designing a basic jet. 100% is fine for doing a pure Pilot Assisted flight but for keyboard piloting it's too much. 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. 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. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Interesting, though even being exponential theres a chance it starts out so small it takes longer than a takeoff to reach noticeable levels. You can park a ship into an elliptical . Kerbal Space Program max Surface Sample storage? Please see the. Any plane needs speed - so you need thrust (usually). It's unlikely you're doing this but just in case: while on the ground use only yaw controls to change direction, don't touch the roll controls. 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. Wings have been flown both with and without struts, Wheel friction was even decreased to 0.3 for front wheel and increased to 2.0 for rear wheels, as per a tip found online. Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? I've had a lot of people comment that their planes veer off the runway or flip around madly even though they think they got everything right. And one other, more remote possibility to check: Where is your plane's center of drag? Really nice overview and some incredible looking craft! 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. Right click on the control surfaces and knock down the control authority of each item. It's a flatbed freighter suitable for shuttling base modules to and from the surface. I'm going to strongly suggest using the angle set to 90 degrees + symmetry mode to place landing gears. Also hopefully you're not using any mods that use throttle (Throttle Controlled Avionics etc) as with engines as sluggish to react as jet, this is bound to cause trouble. 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. Embedded hyperlinks in a thesis or research paper. if that does not work, lower the spring strength until it works properly. You may need to change control authority to a negative value if they bend "the wrong way". Imagine that first plane but with the bubble cockpit and the old style round intakes. @gokcet @DANKTER I usually run my front wheel override friction on 0.3 when the front gear has steering disabled, it needs lower friction. 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. 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. Ok, the panther engine is still not good enough. Before building planes though, there are some inportant things to know. Whiplash is the engine you would want to use on a plane meant to go 20km. There are some really useful tidbits here which deserve some credit. It is also said that a good landing is one you can walk away from. 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. 5. Also: high proportion of lifting surfaces to non-lifting surfaces. Kerbal Space Program, how do you disable autosave? In 5e D&D and Grim Hollow, how does the Specter transformation affect a human PC in regards to the 'undead' characteristics and spells? 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. 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.
