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.

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. 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. hope you and others find that useful in the future! Upload or insert images from URL. The procedure for a vertical take-off is as follows: The procedure for a short take-off is the same, except that forward jets and hoverjets will both be ON from the start. Powered by Invision Community. I used the angle snapping feature (to the right of the symmetry selector in the bottom left hand corner of the screen in the space plane hangar view) to mount the steerable wheel perpendicular to the ground, and the two fixed wheels symmetrically such that zoomed in, the wheels themselves are perpendicular, though the fixed wheel part itself comes with something like a 45 degree angle between the wheel and the shaft that attaches it to the craft, so the shafts naturally sit at something like a 45 degree angle out to either side so the wheels can sit perpendicular. Of course the cargo capacity is less than with a HTOL since you're using some of it to haul those vertical thrusters. Really nice overview and some incredible looking craft! Plane - Kerbal Space Program Wiki - but they were talking about having two intakes/engine. In that vein I drag optimized the Karmilla, and added science parts. I was a diehard rocketer (5k hours or so) until a month ago and then suddenly got the spaceplane bug, I can now see why some people (*cough*Val*cough*) come out with dozens of designs: it's neat when it works so well. 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. 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. I'd start with a lawn arrow that can be hardly pulled up, horrible to maneuver, with CoL way behind, but rock-stable. You would need a lot of orbits at 69 km to come down into the ground. Your very own tutorial.). If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. Stunt planes tend to go for the latter layout and use powerful ailerons, because getting more roll authority is easier than getting more pitch and causes much fewer knock-on effects. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. Your choice of RCS jet is the Place-Anywhere or the Vernor. This one is balanced with reaction wheels. I was hoping that the new intakes would give it the added altitude. 3. These should be in the bottom left next to the display of the cost of the aircraft. 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? Or about the same speed but 1000 m higher. If additionally you can give it a controlled tilt and hold it there, then it'll start accelerating in that direction, like a helicopter. 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. These tend to handle . 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. 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. If you believe your item has been removed by mistake, please contact, This item is incompatible with Kerbal Space Program. Why don't we use the 7805 for car phone chargers? That way you can tuck them away for normal flight, and expose them for hovering. Use Pilot Assistant - it's SAS is meant for aircraft rather than general ( read: rocket ) use. It's said that takeoffs are optional but landings are mandatory. The solution is to house the hoverjets in a cargo bay of some kind, with the doors opening downwards. It is certainly possible to make VTOLs that can circumnavigate the planet. 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. Control surfaces near center of mass sometimes get "confused" as to their role and do stupid things. So basic, anyone can do it. Your previous content has been restored. But it flies horribly, it's all over the place even with SAS on it doesn't fly even remotely stable. About the landing gear, the best way to stop the weird self steering issue is to increase the spring and damper strength. @gokcet @DANKTER I usually run my front wheel override friction on 0.3 when the front gear has steering disabled, it needs lower friction. 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. 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. But mostly, the answer is still "because they're fun and educational and you can.". When your airspeed is near zero and you're above your landing spot, reduce throttle until you start descending. 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. What is this brick with a round back and a stud on the side used for? Now to try it on one of those high altitude missions. @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. Your link has been automatically embedded. But it should most definitely be in front of it, and preferably NEVER move behind it, even with empty fuel tanks. Touch down, CUT throttle, CUT engines, BRAKES ON. It's a flatbed freighter suitable for shuttling base modules to and from the surface. Which was the first Sci-Fi story to predict obnoxious "robo calls"? To do this, take a few barrels of your jet fuel, stick them on the back of your aircraft. @gocket the reason why your solution works is because you are counteracting the imbalance of friction in the wheels as they wobble. Your airspeed will also fall. The ones that are at an angle must be placed at that exact angle, you can't angle them to make them wider. Rockets are much less efficient than air-breathers, so it needs to be much bigger than a Kerbin-bound craft performing the same mission! The twin-boom design is one of my favourites, largely because it looks cool. This happens in two instances; initial placement and plane body deformation. There's no tutorial in KSP that explains plane design to you and this guide could have taken the lead on that. These tend to handle best. The BAK Zephyr, a rocket-powered VTOL craft designed for conducting science missions on Duna. The main challenge for hover control is to keep the craft horizontal.

And start small. Also stock fuel priority is in 1.2, allowing very stable CoM builds. 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! Set the thrust limiter on your main engines to zero. In the crash log, it says that at 00:00:00 there is "Lift-Off!" 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. 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. Please consider starting a new thread rather than reviving this one. Otherwise tune the suspension to keep takeoff and landing stable. This is always my strategy for building planes (although sometimes things go horribly wrong for a different reason.) The same applies to Laythe, although it has gentler topography. 4. The hoverjets are housed in the big wing-mounted pods. a craft that's designed to fly aerodynamically, using lift produced by lifting surfaces. front, then it automatically disbalances the weight moving the weight to the back. In other words classic tripod. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). 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). By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. They sometimes coincide with ailerons on some, more space-economical, aircraft. Set the thrust limiter on your main engines to zero. One of the most finicky problems with VTOL craft is managing centre of mass. By 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. All trademarks are property of their respective owners in the US and other countries. 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. It flames out at 25,000. 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). 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. You know you don't have enough if you're getting engine flame-outs on take-off or, worse, landing. Air-breathing hoverjetsneedintakes. Ok, you will want to start building. Any plane needs speed - so you need thrust (usually). In 5e D&D and Grim Hollow, how does the Specter transformation affect a human PC in regards to the 'undead' characteristics and spells? All rights reserved. When you're close to it, INCREASE THROTTLE until your rate of descent nears zero. Take the large delta wings and place them on the aircraft. 5. If his problem is the plane doing backflips at a touch of 's', I wouldn't go with 'slightly'. Remember the, fuel flows from the front in KSP, so you might want to start off with the CoM in front of the CoL. Most of my planes I'm able to knock each of them down to 40% and still perform 7-8G maneuvers. Kerbal Space Program, how do you disable autosave? It only takes a minute to sign up. Thank you for posting this. The writing is a bit disjointed, because it's been edited and restructured a few times andI'm not a native english speaker. @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. Some more advanced tips you can use in the guide: In stock (no FAR) game to have a stable plane its also important to place control surfaces behind the wings, since their lift increases faster with AoA. You want to keep the CoL slightly behind the CoM, but not too much to not create torque. Then: I hope you've found this short tutorial useful. that being said, one thing I noticed is that you said the whiplash is for SSTOs, this isn't true, it's used for high speed atmospheric flight, it doesn't have a closed cycle mode, so it can't be used to complete an orbital trajectory. 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. KSP should be handing out engineering degrees :). There are a few missions for which a VTOL aircraft is ideal. You too!Like - Subscribe - Check out my other tutorials. 2) Then add the pitch control surfaces. Wings on the front of the craft can cause pitching and rolling, causing you to hold W constantly. At low speeds, this difference can be significant. Hovering is expensive but you don't really need all that many seconds of hover either for take-off or for landing. 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. Interesting design!! You need enough intakes to keep them fed. 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. 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. Privacy Policy. Paste as plain text instead, 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=. 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 :( ). 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. The most helpful thing to do would probably be to make a craft and share it so things you're doing wrong can easily be pointed out for you to fix. The Kerbal Space Program subreddit. Have you set your control surfaces to only respond to appropriate controls? Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. They can be placed on wings. CoL (Blue ball) position relative to CoM (Yellow ball) is very important. Guest, You arent doing anything wrong. Do you have a picture? Your CoT vector will disappear. ps: use caps lock(fine control) to reduce the amount you're actually moving the control surfaces. The more intakes added, the higher a plane can go before a flame-out, which makes multiple intakes a must on SSTO spaceplanes. 2023 Take-Two Interactive Software, Inc. More air is better. However, don't put any fuel tanks on it yet, and empty any fuel-containing parts that you are using.

This page was last edited on 17 December 2021, at 13:14. Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0? Because they're fun and educational and you can. A Screenshot of Kerbal Space Program. It is also said that a good landing is one you can walk away from. It also depends on whether you're using FAR or another aerodynamic rewrite mod that would change the way your aircraft behave. Such a simple and basic tip, but so unknown throughout KSP. I've always found that best way to not crash on the take off is to take off. Try not to make your first airplanes longer than 3 MK1 fuselages. 2 will usually do nicely, but 3 or 4 are usually better (but of course heavier, and this tutorial assumes you use 2). 1. Thank you and happy landings. 2023 Take-Two Interactive Software, Inc. You cannot paste images directly. Can't remember where I saw/read about it - Scott Manley maybe? And one other, more remote possibility to check: Where is your plane's center of drag? They optimize use of oxidizer in SSTOs. You may need to change control authority to a negative value if they bend "the wrong way". 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.
