#2 DaSkippa Mar 14, 2014 @ 2:56am as Shkeec said check gear check gear check gear. Enable mirror symmetry to save yourself some alignment effort. Landing speed (minimum speed for level flight) can be reduced by adding components to increase maneuverability, by using larger wings, by increasing wing angle of attack on the fuselage (3-5 degrees is the recommended range for a spaceplane to achieve the best lift-to-drag ratio [source]), and by decreasing the weight of the aircraft. Saves a lot of headache in wheels placement. 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. This allows you to takeoff at lower speeds and on shorter runways, and likewise for landing. You probably won't have much luck landing the fuselage intact if your Mk3 plane gets its wings scorched off on reentry. It doesn't really matter if you angle them or not, there is not a single configuration for the wheels that can work on all plane parts. This would indicate two problems. Even if you can takeoff, landing will usually destroy tat aircraft so survival rate on an aircraft for a typical kerbal is nearly zero. 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. After placing wheels I always use the rotate gizmo on snap with absolute orientation. This plane will be able to take off, travel somewhere, perform a crew report, and then land. I am definitely aware that there are multiple reasons as to why the plane flips. How to keep an airplane stable on the runway in Kerbal Space - Arqade 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. You can also use parachutes on landing, but care must be taken to ensure that an adequate length of runway remains since you'll only get one chance to use them. While all other cargo bays are fine for making spaceplanes, the Mk3 Cargo Ramp produces obscene amounts of drag, which can easily prevent reaching orbital velocities by itself. (Yes, you personally, you lucky thing! Now imagine what happens like that. I checked my planes and I found the problem. Brakes in the back keep you stable. When flying straight the plane is pretty stable but pitching up causes a sharp roll and I cant figure out why. 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? The SSTO I took to Laythe recently has only one minor flaw using this design, I have to raise the landing gear and pull back slightly to take off. - KSP - YouTube 0:00 / 31:25 Flying a Space Station through a GAS GIANT! This is generally an issue of not spacing your landing gears out far enough apart. Ailerons to roll your aircraft should be placed as far off to the edges of your wings as possible. LV-N has less than 25% of its full power at Kerbin sea level. It is also said that a good landing is one you can walk away from. symmetry building makes them face slightly towards (or away from) each other, with wobbly results. When dealing with high-speed landings, you may touch down too quickly and cause the front of the plane to smack into the runway. Press question mark to learn the rest of the keyboard shortcuts. If rear landing gear are strutted together, or braced to a center point, they are less likely to torque in different directions. 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. Firstly, inadequate air intakes for the number and type of engines you're using (causing some engines to shut down before others). 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. You may also want to deploy your landing gears to increase your drag, as well as airbrakes if you have them. You need to make sure that the Orange axis on the rotate sphere is parallel to your, nose-tail axis. Easier just to bring the rear wheels closer as well as a in line reacton wheel. How wide is the base. I was wrong. A Ravenspear Mk3 taking off from the Runway in version 1.0.5. I've had stability issues in planes where I'd have proper gear setup, balanced weight and lift. 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. Also, excessive use of the rudder usually causes the plane to spin out of control and crash. 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? Thanks for all the help. Here is your convenient solution to this problem! Clear editor. And, of course, try to take off and land as slow as possible. This is also the same reason why planes start rolling toward the middle of the runway; because both ends of the runway are further from . As you approach 35-50 km, your aircraft will most likely level itself out, at which point you can try aiming about five degrees above the horizon line. 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. I don't have any mods but sometimes a problem may be a simple bug. Plane spins/lurches to the side during takeoff? :: Kerbal Space Program Set up for a long glide path, and watch rate of climb indicator at top of screen, aim for -5 m/s. How to Fly a Plane - KSP Beginner's Tutorial - YouTube 0:00 / 25:53 How to Fly a Plane - KSP Beginner's Tutorial Mike Aben 30.6K subscribers 78K views 2 years ago KSP - Absolute Beginner's. mods used are OPT for most of the body and the front canards and tail plane, B9 procedural wings for the wings, and mk4 spaceplane parts for the engines. That said, parachutes are an exceedingly effective means of reducing your stopping distance. Even a small deviation can cause serious instability, making your aircraft bounce and jolt left and right even during takeoff. They could go up to 120 m/s on the runway and still not lift up. What you ought to be using is the Swept Wings and Elevon 1s instead of the Delta-Deluxe Winglets. Cookie Notice Note that dropping off cargo from the back with a Mk3 Cargo Ramp is bad for more than one reason. Keep your spaceplane pointed about 90 degrees above prograde so that the wings and body of your aircraft slow you down as much as possible. 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. Quick context, I am a software engineer. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. Some testing is usually required with new designs to determine the best ascent profile. This page was last edited on 19 February 2020, at 07:08. S5 moon rocket by lightbreaker_64. All lift-rating means is that the wing section will resist motion perpendicular to its plane. 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. - KSP Matt Lowne 527K subscribers 1.3M views 2 years ago I've wanted. You should have something called an "Elevon 1"; this will be the moving part for your wings. Also avoid the basic fin for the same reason. However, it's not a matter of "atmosphere or not", just a matter of air pressure which decreases rapidly with altitude. wings, unless they're very well braced). . Check out the following guide for some good info: Your wheel base is the problem. It's said that takeoffs are optional but landings are mandatory. There are several forces in Kerbal Space Program which have an effect on the flight characteristics of SSTO craft. Place your rear wheels/gear in front of the flaps on your wings. Kerbal Space Program 2's early access launch is only for seasoned The problem could be due to several issues. You want an elevon on each set of wings. 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. Now I'll walk you through a basic aircraft; fancy stuff like science equipment can be added later. 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. This is good for spaceplanes operating in low-oxygen atmospheres where jet engines can't be used. 1. make sure your main gear is not wobbling (ie. 2022 Take-Two Interactive Software, Inc. Here is your convenient solution to this problem! - SF. 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. http://kerbalspaceprogram.com, Press J to jump to the feed. Suggest a Correction Copyright 2023 Nexstar Media Inc. All rights reserved. As lift increases you remove some strain on the gear, however you've just increased the amount of sag. Your wheels should now have 0 degree angle between them, meaning they are both. Tutorial:Aeris 4A mission - Kerbal Space Program Wiki They sometimes coincide with elevators. 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. Note that canards are somewhat more efficient than horizontal tail fins since canards provide an upward force with upward rotation, and downward force with downward rotation. KSC's runway is slightly north of Kerbin's equator and perfectly flat. Keep your nose pointed prograde as you descend through the atmosphere. So I have played the game for 200 hours and I love it. Temperature tolerance is the primary consideration for fuselage choice. Is there a way to rectify this problem. The most dangerous part of a spaceplane flight is returning from orbit. You cannot paste images directly. The reverse also happens. This aircraft can takeoff at just above 50 m/s and can glide for a few minutes without engine. Upload or insert images from URL. Another trick is to move the rear landing gear forward, closer to the center of gravity. This tutorial was created primarily based on a Reddit post by the incredibly helpful u/AnArgonianSpellsword. 3. make sure your center of mass is slightly in front of center of lift force. The centre of mass was between the 2 landing gears. So yesterday I was playing some KSP2, and resumed the game from a save where I had landed in Duna. You cannot paste images directly. When your spaceplane rolls shortly after touchdown, veers to one side and then explodes on the runway, you have a problem with landing stability. For myself, it always was the position of landing gear in terms of pitch. 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!). When your altitude reaches 35km, start pulling up gently. I scoured the entire web for a solution, but found no working solution or at least dont work every time. 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!
