2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. How to tell which packages are held back due to phased updates. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed. The most efficient way is, of course, to make a high altitude (or space) plane. This lowers their effective "weight"-- for example, a craft flying at 1400 m/s on Kerbin is effectively flying as if gravity were only 2/3 of its actual value. Simply changing the intakes made it fly completely out of control and impossible to land. Upload or insert images from URL. Build a plane or rocket for Kerbal high altitudes, We've added a "Necessary cookies only" option to the cookie consent popup, Screenshot of the Week #85 [Submissions Closed - Vote Now!]. In addition to the traditional giant tube of explosions that flings things up high approach, Kerbal Space Program includes a very useful piece of equipment that became quite popular in the 20th century: wings.. To get higher with the low tech jet engines, you need rocket assist. Challenges Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. You are simply running out of atmosphere (i.e. Yes, although they have only been flown with nearly full tanks. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. Pvt. I didn't try for 20000m as it probably wouldn't do well. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. You could try combining the two. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. Thrust means that slower-is-better no longer applies: now, slower means less drag but more gravity, so there's a tradeoff (which I'm not going to carefully calculate for you, because it's hard). edited 6 yr. ago. Thanks for asking this, I've been struggling with the same problem in career mode. Please consider starting a new thread rather than reviving this one. Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. Is it even possible? I looked into the .cfg files and there are no special properties allocated to them. It only takes a minute to sign up. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Another problem is jet engines stealing fuel from the rockets' tanks - you may want to pump the fuel manually (requires an R&D centre upgrade) or add some pipes between them. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. Now I have a plane that will fly around the world at an altitude of the low-20s. If the wings are flat and your plane steadily loses altitude in level flight at a given speed (as most designs will by default), it means you either need to pitch up slightly, increasing the angle of attack and keeping your vertical velocity at 0 by flying up slightly to compensate for the pull of gravity that lift isn't compensating for. And it's stock, unfortunately. If it's below the cross-hairs, you need a little more AoA. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Ep. As long a you can fly faster, the lower density at altitude can be compensated for. By climbing, you reduce drag, exponentially with altitude. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. Should i add a larger wing area for higher lift? Your answer got me in the right direction, though I ended up with a different design (see my own answer). That's because wings need to have some AoA to the airstream in order to generate much lift. I don't have the numbers handy, but you can expect something like 400m/s at 15km. 2022 Take-Two Interactive Software, Inc. First off as of .15.1 intakes don't do anything. You cannot paste images directly. I was hoping that the new intakes would give it the added altitude. A jet engine from KSP 0.18 A jet engine is an air-breathing engine which uses onboard liquid fuel and combusts it with the oxygen drawn from the atmosphere. 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. How can I make money in the new career mode? This makes jets built using this engine considerably more maneuverable. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Even up there the plane acts squirrely. Immediately starting rocket engines at full throttle turned out to make most of my aircrafts totally unstable, turning them up gradually worked way better. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. 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. How do I align things in the following tabular environment? All the information you could want to know about science, including the altitudes for each celestial body, and what altitudes a given experiment works on are available at: http://wiki.kerbalspaceprogram.com/wiki/Science. Clear editor. It's Kerbal Space Program v.22! Are you using Stock or NEAR/FAR? KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. High altitude planes - Kerbal Space Program Forums The drag differential is because your long-wing layout is using a bunch of struts, and the reason your delta-wing has a higher ceiling is because it has more wing area to provide lift. Paste as plain text instead, Or is it the same for all celestial bodies? 2/3 (KSP 1.11.2) - YouTube I break out the Mk2 parts and Panther engines to build a better jet that can go higher and faster. Subscribe -. Jets drop thrust at higher altitude and speed, but also drop . Incidentally, for these speeds and altitudes, ordinary jets are the better choice. Either of the two speeds are to be avoided. Pasted as rich text. Planes and Altitude differences. :: Kerbal Space Program General Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane Do you know how many intakes/turbojet are needed to run in the regime you described? I decided to look into that two intakes thing, and it turns out to make 11-12 m/s difference at 19,000m with my plane. As said above, the Wheesley is specifically designed as a low altitude engine. http://kerbalspaceprogram.com, Press J to jump to the feed. I don't recall if they model aspect ratio, but either way, the struts are murder and the delta wing has so much more wing that it'll still have more lift. Dedicated to the growth and advancement of amateur rocket scientists! In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". I followed a similar strategy. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Is it possible to get to an altitude of 16-20km with normal plane engines? If you upgrade to the panther (or get one on a contract) that engine can get you much higher. This thread is quite old. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Let me share what I know about jet engines, speed, and efficiency. Cheers again fellas. The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. J-404 "Panther" Afterburning Turbofan - Kerbal Space Program If it's above the cross-hairs, you need a little less. Content titles and body; Content titles only Note: Your post will require moderator approval before it will be visible. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. Rockets aren t the only way to get to space. What determines the maximum altitude a plane can reach? I don't have that other stuff yet. Air temperatures vary with latitude and time of day. Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. It was meant for low altitude flight. Press J to jump to the feed. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. Display as a link instead, Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Have a plane that ditches its wings and rockets up to 18km once you reach the right point. The more successful the flights, the more successful the space program is. This means it is better to have excessive amounts of oxygen than not to. This is my current best hi alt plane. Kerbal Space Program ( KSP) is a space flight simulation video game developed by Mexican developer Squad for Linux, OS X, Windows, PlayStation 4, PlayStation 5, Xbox Series X/S and Xbox One. @SaintWacko's advice is probably the most practical. KSP Quick Guides: High Altitude Design and Flying - Stock v.23 Stoober AK 3.32K subscribers Subscribe 21K views 8 years ago This tutorial will cover designing and flying a plane that can soar. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Yes. In this case lots of fuel is the wrong approach, I can get more than half way around Kerbin on 2 cans of Jet Fuel and a turbojet if I glide most of it.

A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. June 3, 2022 . Kerbal Space Program Jool Landing Youtube. - "In Space High" means your craft is inside the given Sphere of Influence and above the "Space Border" altitude listed in the Celestial Body Multiplier Matrix. Evidence. Air Flow + max. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). Turbojets are so ridiculously efficient that it doesn't really matter. It may work with stock too, I just don't know. At that point your engines will be running about .7-.8 efficiency and you will be out of the thicker atmo which will allow you to go faster. With some fins to keep you stable and careful aim, you can hit your desired location and altitude and will have 5-10 seconds to collect data before you hurtle past it and pull your chute. For more information, please see our But you'll need to unlock: Which cost 300 science. I've been finding it difficult to build a jet that can fly over 15km alt. All trademarks are property of their respective owners in the US and other countries. I would like to know which altitude I have to maintain for my experiments. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. You can post now and register later. As has been said, ISP is nothing to worry about. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. air) that high up. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. a screenshot of kerbal space program 2. by: lord bird. My question is really about controllability. Connect and share knowledge within a single location that is structured and easy to search. Designing a High Altitude Jet | KSP: Making Space Home The best answers are voted up and rise to the top, Not the answer you're looking for? Anyway thanks in advance. You are just about at maximum speed and at the same time very close to stall speed. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. This tutorial will cover designing and flying a plane that can soar at high altitudes! Whiplash is the engine you would want to use on a plane meant to go 20km. If that's all a case of Too Many Words, think of it this way: Suppose you just build a plane the "default" way and don't put any. So long as there's only one high-altitude measurement to take, you should be able to complete a whole set of 3-4 in one flight. I start with the normal jet engines (which takes almost the complete runway). KSP Career: Episode 13 - High Altitude Surveys - YouTube Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Your previous content has been restored. Also, jets eat fuel at pounds-per-minute -- if you cover twice as much ground in the same time, your plane will be more efficient. Kerbal Space Program - All Easter Eggs Guide All rights reserved. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Plane - Kerbal Space Program Wiki Thanks for the help! 1 1: The basics 2 2: Setting it up 3 3: First flight 4 4: Finishing touches 1: The basics First of all, you're going to need an airplane. Powered by Invision Community, Thanks, I'll go try to stuff a few extra turbojets and intakes on my plane, I was generally under the impression that basic jets were mostly deadweight on high-performance aircraft: [] at hypersonic velocities. TLDR: You need parts you don't have to make a plane that flies that high. 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. As long as the engine gets enough air it will work at proper efficiency. Note that KSP planes get one substantial speed benefit that's much more pronounced than IRL aircraft, due to the freakishly small planet sizes: they're actually flying at a large fraction of orbital velocity. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Paste as plain text instead, You can go above 20km with the J-404 Panther. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. There are two factors to that: how thick the air is, how fast the ship is going. Powered by Invision Community. [Solved] 30 20 / This thread is quite old. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. No, I think it's correct, unless I've got a brain fart going, here. Kerbal Space Program 2 . With only panthers unlocked I might add. If you want to cover your aircraft with loads of intakes, I'm sure you could easily fly above 35km and reach 2000+ m/s velocity. http://www.youtube.com/user/Cruzanak?sub_confirmation=1Quicklinks to topics in this videoJet Engine Concepts: 0:30Air Intakes: 1:13Flameouts: 2:22Control Surfaces: 5:08Flying Tips: 5:57This video will go over everything that you need to know about to design a capable plane that can fly in the thinnest of atmospheres. Not only does it conk out at high altitudes, but also it conks out at high speeds, and you need to be able to go fast to fly up high. Sideslip handling. Which lets you go faster, which lets you climb higher. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. Your link has been automatically embedded. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. That annoys me but I can't seem to get a design to make it work. 2.) Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. Thats my problem right now. Grichmann's answer has been the most reliable way I've found to complete these missions. Planes in Space. But my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. Airplane Plus on SpaceDock The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). Been a while since I've flown stock*, but I've heard that, for maximum efficiency, you want one turbojet for every 7.5 tons, and about four ram intakes for each turbojet. 2022 Take-Two Interactive Software, Inc. Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. Though I'm still working on learning to be better at space planes. Valve Corporation. Using very light "engine rich" planes and "reverse swooping" (building velocity at 10km then gently curving up) you can temporarily get above 20km with Wheesely and Juno. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. Create an account to follow your favorite communities and start taking part in conversations. I was even able to do this with three pairs of Junos instead of the large jet engine pair (I don't have the technology level for that). So now to come to an end: from my experience I'd say for a medium sized aircraft it is best to fly between 12-13 km. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. I'm trying to build a high altitude plane and have found out that the rules are different. Control Sensativty for Planes - KSP2 Suggestions and Development probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. If you have an account, sign in now to post with your account. Personally, I don't enjoy survey contracts on Kerbin. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. High altitude (~20km) possible with normal plane engines? Spaceplane - Wikipedia as a rule of thumb they all lose thrust at higher altitudes and at high velocities. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. When I say ", You know you've nailed it correctly if, when you're in level flight, your. Proceed with caution. "Whiplash" Turbojet. The benefits should be obvious. This is the first version. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. You need to do it with what you've got. The main body is a fuel tank with a Swivel engine at the end. Cookie Notice The second, Wet mode, uses the afterburner to produce thrust almost equal to the J-X4 "Whiplash" Turbo Ramjet Engine, but at a considerably reduced fuel efficiency. The Panther engine can hold 19,000 steady and oscillates around 20,000. It may take some practice to hit your target area this way, because you'll be picking up additional horizontal speed, and thus it's possible to under or overshoot. You can post now and register later. - Insane lift to weight didn't help. 3x06: I design a new, high altitude, jet to collect high atmospheric science. Air Flow: Air Flow represents with how much force air passes the turbine (notice: different amounts of air at the same speed equals in different amounts of force!). alternatively, combine a liquid fuel rocket into your plane. Jet engine - Kerbal Space Program Wiki Don't rely on the efficiency indicator! Highest and fastest possible is best. Laythe - Kerbal Space Program Wiki For all your gaming related, space exploration needs.
