ksp plane takeoff

You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. My plane usually take off at a little over 120m/s. I found biggest cause of this as well as not being able to possibly correct is having sas on during takeoff, make sure that is off during take off and should find problem is less likely to occur, but I too struggle to make working space planes even when center of lift, mass, thrust are all as needed. Note that the lift rating does not mean that the wings will automatically lift a spaceplane into the air when it's moving forward. 67K subscribers in the KerbalAcademy community. For spaceplanes, avoid the FAT parts (wing, tail fin, and control surface). Thanks for all the help. Any ideas? Brakes in the back keep you stable. 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. It is advised to place your control surfaces as far from your center of mass as possible. Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. Create an account to follow your favorite communities and start taking part in conversations. Descending greater than -10 m/s usually makes a mess. I see absolutely no need to be traveling that fast down the runway. For this to happen, I'm assuming you're using rocket fuel tanks. Your aircraft might just be too heavy - there might not be enough wing lift for it to take off the ground. I started investigating why this was happening. I feel tat it is either due to the symmetry placement in this game being inaccurate or certain parts where i anchor my landing gears on are not perfectly symmetrical and the physics calculation is just too sensitive about even the slightest misalignment. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. I'm making sure that I keep trying to get it up but it just wont go! You can post now and register later. Alternatively, you can try landing at higher speeds with your nose pointed further down, but this increases challenges with stability and deceleration while on the runway. 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. One FL-T100 tank can't power any rocket into space, yet a Shock Cone Intake, a Mk1 Inline Cockpit, a half-filled FL-T100 and a J-X4 "Whiplash" Turbo Ramjet Engine aimed in the general direction of "up" will let you laugh your way past the 70km mark at nearly 1200m/s. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. (For test purposes, all aircraft are not pitched up and SAS is turned off. Display as a link instead, 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. I managed to successfully takeoff and land this aircraft at least 20 times in a roll now and I haven't even lost a single pilot flying this. "Type E" is the smallest you should have, and you want a set of those connected at the back of the fuselage. * Gear not mounted to parts that will flex (e.g. my planes keep flipping backwards on take off . See if there is still a problem when only travelling slowly, say <20m/s. They sometimes coincide with ailerons on some, more space-economical, aircraft. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. 1. tilt of the plane. You're going to have a bad time. It is due to the spinning up of the engines. This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. 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. Pasted as rich text. The Whiplash's ridiculous fuel efficiency allows a spaceplane to climb high into the atmosphere and gain a lot of speed while barely using any fuel at all. I worked through the tutorials and I think my problem was most often a lack of lift, or perhaps more accurately sufficient control surfaces. The rudder is mostly used when landing and when attempting to line up a shot (in a fighter plane). Place your rear wheels/gear in front of the flaps on your wings. I have found a solution to my problem. All rights reserved. Do agree that the rear wheels either need to be brought closer or or the Nenter of mass needs to be move closer to the rear wheels. It's said that takeoffs are optional but landings are mandatory. Also pay attention to your fuel balance, especially if you're using several tanks placed in parallel to each other. I made a KSP replica of the Horten Ho 229 while trying to make a short takeoff plane.If you have any questions or suggestions, let me know in the comments.My. Be aware that while this angle will provide the lowest possible landing speed for your spaceplane, it will create problems if your center of gravity is too far ahead of your rear landing gears (causing a high-speed nose collision on touchdown) or if your rear landing gears are too far ahead of your engines, causing them to strike the runway first. If you plan on either dropping off cargo or picking up cargo and traveling with it, you'll generally want to locate your cargo bay at the middle of your center of gravity. KSP 2 speculation: I believe terraforming will be a feature of the game. When you are near the end of the runway, quickly activate then detach them to get the nose pointing up. If you use an Advanced SAS, and raise your front landing wheel so that it is higher than the rear wheels, by just turning the SAS on and going full throttle, due to the 10 degree angle of the plane, it should eventually take off by itself. (Yes, you personally, you lucky thing! Managed to fix it with some different wings; idk what was going on with the other ones but I was just thr FAT aeroplane wings. LV-N engines also have the advantage of using the same liquid for propellant that jet engines use for fuel. A Ravenspear Mk3 taking off from the Runway in version 1.0.5. If you're planning on landing on a somewhat uneven surface, like an open grassland somewhere on Kerbin or an island on Laythe, consider packing some parachutes for deceleration. The FedEx plane pulled back up in time to avoid a collision. * Unlock steering and disable brakes on front gear. Go on, and take the plane capsule which looks like a converted fuel storage device. Close to empty tanks will allow you to fly slower, decelerate faster, and reduce touchdown strain. Take the large delta wings and place them on the aircraft. With a tail-dragger, the plane is already angled up just sitting on its wheels so once the speed is high enough, it should just float up by itself. @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. One idea I haven't noticed here yet: "wire up" the landing gear, with strut connectors. KSC's runway is slightly north of Kerbin's equator and perfectly flat. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. 6.4K Downloads Updated Jun 7, 2017 Created Jun 7, 2017. . You can post now and register later. Second try, speed over land reached over 210 m/s and it didn't flip. Not sure why you would want that stability for speeds in excess of 200 m/s though, as most planes will take off and land at far slower speeds. When your jet engines stop working, it is time to ignite the old, reliable liquid fuel engine. Or maybe launching it in a vertical, Space Shuttle-style config. When I Start Why Engine, It Goes Straight But As Soon As I Takeoff. However, it's not a matter of "atmosphere or not", just a matter of air pressure which decreases rapidly with altitude. These have an ISP of 800 in a vacuum which is significantly better than all other rocket motors except the very weak IX-6315 ion rocket. A control surface with 100% control surface portion will weigh twice as much as a wing with the same lift would weigh. If you have seen the examples above, I have planes that have angled landing gear and they work perfectly, yet some planes with straight landing gears don't. You can deploy your chutes just prior to touchdown for rapid deceleration. Cookie Notice With initial passes, you start off with a periapsis at 50-60 km and gradually lower your apoapsis until you're in an almost circularized low orbit and then transition to your usual re-entry approach. When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. LV-N exceeds 75% of its full power at just 7700m altitude on Kerbin. 2022 Take-Two Interactive Software, Inc. For all your gaming related, space exploration needs. Here is your convenient solution to this problem! 2022 Take-Two Interactive Software, Inc. http://kerbalspaceprogram.com/forum/showthread.php/13851-The-woes-of-building-a-space-plane?highlight=woes+spaceplane. Now for the engines. 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. I checked my planes and I found the problem. As the title says, my plane dips and turns to the side, clips its wing on the runway and loses it, does the same on the other side, then crashes and explodes, without even getting airborne. Real planes do this as well. (Idea is moot, if you haven't unlocked them yet.) So if I start encountering wobble it's time to pull back on the stick and get in the air. Check out the following guide for some good info: Your wheel base is the problem. Bit late i know, but i had the same problem. Cure: Draw a mental axis from the nose to the tail of the plane and use the rotate tool (summetry on), on one of the wheels. 200 m/s runway stability just doesn't seem to have a worthwhile purpose to me, and is inducing counter productive engineering challenges. wings, unless they're very well braced). They all had to use the runway drop to take off. This is all right if their high efficiency saves enough fuel, but that may not be the case in small spaceplanes with limited fuel capacity. Also note that shock cone intakes appear to provide the best air supply at all mach speeds, and unlike other air intakes, they do not decline in performance beyond certain mach speeds. 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!). Also avoid the basic fin for the same reason. To maximize lift, your aircraft should rest on the ground with the fuselage tilted upward at anywhere up to a 25-27 angle so that the wings will end up tilted back at up to 30. The default max stress value is just ridiculous, its like flying in hair gel, everything gets torn apart so easily, like that will ever happen in real life. I was wrong. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! To survive re-entry, it's recommended to start your approach back into the atmosphere at a shallow angle, ideally with a periapsis of around 30-35 km. That's over 2x the normal recommended max. This tutorial will help you with the basics of spaceplane flight, and will help you avoid the most common errors that could ruin your day as a spaceplane pilot! 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. Plane spins/lurches to the side during takeoff? This thread is quite old. Maybe ;making the tailwheel less stiff would help, too. As you would expect, spaceplanes need wings: they have various shapes and dimensions, and they differ basically in lift rating: you will want to have enough lift to keep your fuselage approximately prograde during your ascent to orbit. Landing also often requires rapid deceleration to avoid running off the end of the runway or crashing into a slope when landing on open terrain. Safety note: Disable the brakes on the front landing gear. Edit: I made a simple easy plane in career mode that is both stable and cheap: A trick i've used before is to put modular girders on the sides of the fuselage and putting the gear on the bottom of the girders. Install S5 moon rocket By lightbreaker_64. Clear editor. And, of course, try to take off and land as slow as possible. Increasing the number of intakes will not allow you to continue using your jet engines at higher altitudes. Note that most air intakes tend to produce less drag than aerodynamic nose cones and pointy cockpits, especially shock cone intakes. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. It is also said that a good landing is one you can walk away from. Before you can make a successful plane, you must understand what makes a plane go in places other than the ground - the wings. If you have an account, sign in now to post with your account. Unstable Aircraft: "FAR Firehound" (Stock). The Kerbal Space Program subreddit. As lift increases you remove some strain on the gear, however you've just increased the amount of sag. - KSP Matt Lowne 527K subscribers 1.3M views 2 years ago I've wanted. If you placed the main wings at the centre of mass and then added the smaller wings behind, this should be correct already. Conversely, if you keep all of the fuel in the back, you may find that your center of mass gradually drifts so far in front of your center of lift that you can't keep your nose up anymore, also potentially resulting in a fatal scenario. EDIT: It was the b9 procedural wings. Balanced fuel saves Kerbal lives. These should be in the bottom left next to the display of the cost of the aircraft. This makes them a very effective choice for SSTOs since they do a good job of getting maximum velocity out of air-breathing mode, and then allow you to use oxidizer without needing the added weight and drag of a separate rocket engine. I have created planes that have landing gears place right under the wing tips but they still won't work. To avoid swerving on takeoff and landing, it is strongly recommended to turn off or reduce the strength of the front brake on your aircraft, as well as to reduce the friction control. You can even try refueling it before recovering your spaceplane further increasing your recovering value. You want to start by attaching a Mk 0 Liquid Fuel Tank under the wings, making sure you're mirrored so it goes under both wings. The issue is my plane rolls very sharply to the left any time I pitch up. S5 moon rocket by lightbreaker_64. A plane is any craft which flies horizontally in an atmosphere utilizing lift primarily generated by wings, winglets, or control surfaces. At around . Keep in mind that as your altitude increases, your control surfaces and winglets will become increasingly ineffective and will no longer work at all once you leave the atmosphere, so you may need to add alternative control systems like reaction wheels or RCS thrusters. Please consider starting a new thread rather than reviving this one. Alright, it's late where I live so I'm gonna hit the hay and come back to it tommorrow, I read on the guide someone sent me and I think it is taht it doesn't have any way of pointing the up, so I'll tinker with some of the wings and see what I can do. While it's true that jet engines don't work in space, they offer one large advantage over rocket engines while inside the atmosphere: fuel efficiency. I shouldn't have placed landing gears on the fuselage, I found that placing landing gears on flat surfaces like wings make landing gears a lot more stable. Then this tutorial is for you. Everything looks perfectly symmetrical as far as I can tell. However, make sure to use struts when placing landing gears on the far edges of a multi-part wing because they may sag enough to cause a fuselage collision with the runway during landing. Privacy Policy. 2022 Take-Two Interactive Software, Inc. Aircraft in this game is almost unfeasible, especially in career mode, you will lose all your money before you finally design an aircraft that can even takeoff. But, likely guess is your craft is not producing enough lift. My plane tends to wobble on the runway with the stock game so i decided to download FAR, but the problem still persists. All trademarks are property of their respective owners in the US and other countries. If you can maintain level flight at about 30-40 m/s, you should be able to perform an ocean landing if needed. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. Heavy transport seaplane inspired to the Soviet Beriev A-40 Albatros which also appears in Evangelion 2.0! 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. Any plane needs speed - so you need thrust (usually). Wing shapes do not appear to have a significant impact on drag or drag-to-lift ratio at this time, but swept wings are still an easy way to help ensure that your center of lift stays behind your center of mass. All of them had one thing in common though. Having landing gears near the front and back of your aircraft can also help to ensure that you won't break your engines or smash your cockpit into the runway. Tips aplenty in this thread: http://kerbalspaceprogram.com/forum/showthread.php/13851-The-woes-of-building-a-space-plane?highlight=woes+spaceplane It taught me everything I know, except for the stuff I learned elsewhere. Consequently, atmospheric reentry is less dangerous with a Mk2 or Mk3 fuselage, compared to reentry with Mk1 fuselages. 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. Note: Some high-efficiency rocket engines lose most of their power and efficiency in low atmosphere. Either put more engines or reduce the amount of rocket fuel. Clear editor. Ideally, the wings should be tilted upward at an angle about 3-5 from the fuselage for optimal lift-to-drag ratio.[1]. That, combined with a Unity joint bug, makes your plane bounce. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Note that as you fly higher the air intakes will become less effective and you may come to a point when the engines will shut down due to the lack of air. Here are a few pictures of it: Take a picture with center of mass and center of lift turned on. However, don't bother going overboard with intakes because your engines will still shut off at high altitudes due to the low air pressure regardless of how many intakes you have. . First, I'm sure this is WAY overengineered, but I haven't gotten to the point of caring about that yet. Nothing bad will happen. #2 DaSkippa Mar 14, 2014 @ 2:56am as Shkeec said check gear check gear check gear. You want an elevon on each set of wings. If you keep all of the fuel in the front, you may find that your center of mass drifts backwards as your fuel drains. This can easily cause you to crash on landing. They are able to operate at higher altitudes and can even continue operating in a vacuum by switching to a rocket mode. 2022 Take-Two Interactive Software, Inc. Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. Heavy Cargo Space Plane SSTO Download. To takeoff and land at low speed, it's helpful to rotate the wings so the leading edge is slightly above the trailing edge. Note: Your post will require moderator approval before it will be visible. When I use it for spaceplane guidance it keeps me on the correct heading, but the flight is very busy sine wave of a path. 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! For example, having your landing gears located near the ends of the wings is an easy way to ensure that you don't roll and shred your wings when landing or taking off.

After externsive testing and bloodpressure rise, results: it doesnt matter where you place the wheels, as long as they are not angled on the X (nose-tail) axis. Your wheels should now have 0 degree angle between them, meaning they are both. 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? 1. make sure your main gear is not wobbling (ie. The problem could be about the angle of wheels, though there could be more problems with the COM and wheels placement. But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls. This page was last edited on 17 December 2021, at 13:14. Because of how small Kerbin is and how high its gravity is, a perfectly flat surface just north of the equator will cause planes taking off to bias to the right of the runway, as if they were rolling downhill. if mounted on not struted part). That way you can use aerodynamics to lower the tail, rather than trying to raise the nose. First try speed over land reached over 210 m/s before flipping in the last second. They could go up to 120 m/s on the runway and still not lift up. I am accelerating it to over 200m/s on the runway just to test the stability of those wheels since the faster you go, the more likely the plane will wobble and flip on the runway. Flying a Space Station through a GAS GIANT! If you've been able to successfully re-enter on previous low orbit test runs, you should be able to use this method to achieve similar rates of success once you've slowed down sufficiently. Controllability of a plane is on you. Note that a Wheesley or Goliath engine can reverse its thrust to allow rapid deceleration during landing, but these are not recommended for a spaceplane due to being unreasonably heavy and inducing excessive drag when attempting to transition to orbital velocities. If you use an Advanced SAS, and raise your front landing wheel so that it is higher than the rear wheels, by just turning the SAS on and going full throttle, due to the 10 degree angle of the plane, it should eventually take off by itself. I have doubled the max stress value for aerodynamics failure in FAR for every category. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. Center of Mass and Center of Lift are the usual causes of instability. If your spaceplane is able to fly and land steadily at low speeds but just you're having difficulty slowing down as you approach the runway, try to reach your desired speed first and then approach the runway in almost level flight. This material may not be published, broadcast, rewritten, or redistributed. To minimize drag, vertical tail fins can be kept minimal, since aircraft can be maneuvered adequately by roll and pitch alone. In subsequent missions, you may want to launch with less fuel to cut down on cost and make landing a quicker and easier process. You should have something called an "Elevon 1"; this will be the moving part for your wings. Your previous content has been restored. A FedEx cargo plane in Austin nearly landed on a runway where a Southwest flight was preparing to take off. If you have an account, sign in now to post with your account. If you pull up and cause the tailwheel etiher to hit the ground if it was already up or push it into the ground if it was still in contact, you will create bounciness. This page was last edited on 19 February 2020, at 07:08. Plane wobble during takeoff - KSP1 Gameplay Questions and Tutorials - Kerbal Space Program Forums Is there a way to place landing gear so that i can guarantee my plane can remain stable on the runway even at high speed in excess of 200m/s? All the weight is pushed on the middle and it can't pull up. 32.5K Downloads Updated Dec 11, 2014 Created Dec 11, 2014. [KSP 2] I'm trying really hard to make a Mun capable ship but this rocket . everytime i make a powered plane, it always flips over and points backwards after i take off. It is also advisable to add some control surfaces to your plane to have some control in the atmosphere: you can manually add them to the wings or choose winglets with effective control surfaces, like the Standard Canard. If, instead, all goes well, then once your jet engines have shut down you will need to start the second part of your space mission by switching to rockets. So the answer is: in the SPH, click on your front gear, set the spring to .5 and set the damper to .5 -- then save it and give it another shot at launching. Depending on which surface you place them on, they might not be parallel to the axis in which case. I moved the back landing gear to right underneath the COM. Or adding a RATO boosters. In an aircraft with two or more engines, this can potentially cause you to enter a flat spin which can be unrecoverable if your center of mass is behind your center of lift. Is there a way to place landing gear so that i can guarantee my plane can remain stable on the runway even at high speed in excess of 200m/s? Powered by Invision Community. Yours is a very light plane, and the standard suspension settings are for a medium heavy plane -- so your suspension is too stiff. Necessary for heavy/long spaceplane. To slow down faster, you can increase the braking strength of your rear wheels. As such, don't use control surfaces as substitutes for wings, and don't use more control surfaces than you need. It provides a wider, more stable wheel base while keeping the wheels straight up and down (no camber). https://wiki.kerbalspaceprogram.com/index.php?title=Tutorial:_Your_First_Plane&oldid=103052. You can also angle the wings themselves slightly upwards (using WASDQE) in order to make them generate more lift when horizontal. KSP Stock Space Shuttle by _ForgeUser18393701. Enable mirror symmetry to save yourself some alignment effort. I have no problems using Mechjeb to launch rockets into orbit, rendezvousing and docking with other craft.
