ksp high altitude planeUncategorized

You cannot paste images directly. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Which lets you go faster, which lets you climb higher. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. 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 -. Yes. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Knowing how to design these types of planes make jumping in to SSTO design very easy as there are only a few minor changes that need to be made.Music Credits:1st Song: \"Elephants\" - YouTube Audio Library2nd Song: \"Hot Heat\" - YouTube Audio Library3rd Song: \"Echoes\" - Kasbo - https://soundcloud.com/k-sboWhat game is this?

As said above, the Wheesley is specifically designed as a low altitude engine. 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. Kerbal Space Program Jool Landing Youtube. . The sweet spot for the upper atmo engines, I find, is between 10k and 12k. Yes. Have you checked out the wiki yet? Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Slap that behind a plane you'll be able to go beyond 20km without any trouble. If your using NEAR/FAR, once you get high and fast, kill the engine and glide to save fuel. 1 Pod outside the level 3 VAB. High altitude flight is efficient because the air is thinner, and therefore aircraft experience less parasitic drag. This page was last edited on 22 December 2019, at 20:54. Listen to this guy, don't go much farther above 15000 with high altitude engines. Clear editor. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude. Your link has been automatically embedded. So that means that even if you are inside the atmosphere but still orbital (such as during aerobraking), your science will not count as "Inside the atmosphere", For example, orbiting Kerbin above 250km altitude, your science is counted as "In Space High over Kerbin." My question is really about controllability. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. Will post my results. Clear editor. I don't have any exact numbers for you, but you can right-click an engine in flight and it will show both current and optimal airflow, which should hopefully let you work out the best altitude. New comments cannot be posted and votes cannot be cast. 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. jet engine efficiency in this game is based on built in thrust curves. - "In Space Low" means your craft is inside the "Space Border" altitude and in an orbital path. Privacy Policy. Most SSTO space planes would be able to accomplish this easily. Let me. What am I doing wrong here in the PlotLegends specification. Grichman's answer got me in the right direction. If it's above the cross-hairs, you need a little less. As I understand, the OP wanted "the most efficient way to fly", and simply needed a bit of help in realizing that that is a hypersonic, high-altitude, high-performance aircraft which is a RAPIER and a little oxidizer away from being an SSTO spaceplane. 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. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. Main goals: Auto-trimming. Another approach, which I was managing with some success before I figured out jets, is to build a rocket and catapult yourself towards the measurement point. Any advices for building a vehicle for this task? Note that you need to activate the afterburner ("Wet Mode") manually. Chapter 4. FBW uses three controllers - pitch, roll and yaw. Your decreased flight time means you probably won't make it to your location.

I did some testing and found that the turbojets get the best Isp around 5.2 km altitude, so I was thinking of flying at that altitude. Originally posted by lord bird: yep thats right jool has a surface. The U-2 is probably the highest altitude aircraft still flying. 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. http://kerbalspaceprogram.com, Press J to jump to the feed. 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. One problem is i'm running stock on career mode and only have 30 part to spare, so large planes are out of the question. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. It was meant for low altitude flight. That annoys me but I can't seem to get a design to make it work. It's also worth noting that this engine has the widest thrust vectoring range of all of the jet engines, with a full 10-degree range in all directions. A temple in the desert (6 29 47 S 141 40 3 W) known as Tut-Un Jeb-Ahn, although this name can only be seen when a vessel crashes into it. So the faster you go the higher you can fly where there is less drag. As long a you can fly faster, the lower density at altitude can be compensated for. Highest and fastest possible is best. Even up there the plane acts squirrely. It has two modes: The first, Dry mode, is similar to that of the J-33 "Wheesley" Basic Jet Engine, with a bit more thrust. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. This thread is quite old. But you'll need to unlock: High Altitude Flight Which cost 300 science. Thanks for asking this, I've been struggling with the same problem in career mode. Arqade is a question and answer site for passionate videogamers on all platforms. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. The main body is a fuel tank with a Swivel engine at the end. What are the minimum altitudes for each warp level? 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. And it's stock, unfortunately. Really. and our - Inside the atmosphere works the same way, except you need to be on an suborbital trajectory. Don't rely on the efficiency indicator! 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. I started by attaching two LV-909 rocket engines to a regular low-atmosphere plane: In this save, I don't have custom action groups yet, so I'm using the RCS control to toggle between jet and rocket modes. I should perhaps start trying out NEAR to get ready of 0.90, though. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. 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. I am currently designing a mission that will involve several very long distance plane flights. 20 votes, 21 comments. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Slap that behind a plane you'll be able to go beyond 20km without any trouble. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. At altitude the nose goes up and down until it goes out of control. air) that high up. Its an approximation missing someelements. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Trying to do something without the right part is long and difficult path. Or you need to put a little bit of angle of incidence in your wings, which will reduce drag since you don't have to pitch the entire plane up, but will be stuck at a fixed angle meaning you'll have to pitch up or down anyway during certain phases of the flight that the plane isn't optimised for. Press J to jump to the feed. Planes in Space. I don't have that other stuff yet. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. That will unlock: 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. What's the difference between a power rail and a signal line? *I use FAR these days, which basically means completely replacing every spaceplane and rocket you ever designed to account for its much more realistic aerodynamics. Whiplash is the engine you would want to use on a plane meant to go 20km. When I say ", You know you've nailed it correctly if, when you're in level flight, your. edited 6 yr. ago. 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. Pasted as rich text. 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.

First is thrust; the higher you get, the lower the thrust your engines deliver. I'm in career mode and got all groups of the 45-science-cost level, except Flight Control, and additionally have Electrics, Heavy Rocketry and Fuel Systems. 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. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. Why that? Rationale: 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 AoA at all on the wings. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . The U-2's published maximum altitude is somewhere above 74,000 feet. Any of my search term words; All of my search term words; Find results in. I would like to know which altitude I have to maintain for my experiments. Range with this method is pretty short due to drag. The other one I stay around 6000 meters. You can do that by right-clicking the engine and clicking "Toggle Mode." 101 kPa 1 atm Scale Height 5000 m Atmospheric Height 69 077.553 m 1.010-6 atm Minimum Temprature -40.19 C 232.96 K Maximum Temprature 20 C 293.15 K Oxygen Present Yes Contents 1 Kerbin 2 Topography 3 Kerbal Space Center 4 Atmosphere 4.1 The Troposphere 4.2 The Stratosphere 4.3 The Thermosphere 4.4 The Exosphere 5 The Kerbin System 5.1 The Mun If you nudge your wing's angle up slightly with rotate tool then it'll move your prograde closer to your direction of flight and significantly reduce drag. with a thrust vectoring range of only 3 degrees.

Using Kolmogorov complexity to measure difficulty of problems? KSP Career: Episode 13 - High Altitude Surveys Mike Aben 28.5K subscribers Subscribe 7.7K views 7 years ago Day 114: A busy day at the KSC with three missions, the highlights being the launch. 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. Sideslip handling. Valve Corporation. Cookie Notice Air Flow + max. 2022 Take-Two Interactive Software, Inc. EDIT: Essentially, make like an SR-71, if an SR-71 didn't have cooling problems limiting it to Mach 3.4. There are two factors to that: how thick the air is, how fast the ship is going. If you have an account, sign in now to post with your account. The other thing to bear in mind is that tuning the AoA (angle of attack) of your wings makes a difference. Your previous content has been restored. Right now, my big, fat plane has trouble breaking 10 km altitude and 200 m/s forward speed (largely due to its payload). Thank you, I was able to reach up to 24km altitude with this design. Yes, you can get into that range with the high end stuff (whiplash engines and ram or shock cone air intakes). high-2 A Screenshot of Kerbal Space Program - Insane TWR didn't help. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. 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. Simply changing the intakes made it fly completely out of control and impossible to land. All other versions are slower and lower and unstable in turns. Be sure to have enough intakes (I think maximum efficiency in stock is 1 ramjet intake per ~2 tons of plane, though that is aesthetically ridiculous), and if you're still running short of intake air, you can dip down a bit to speed up and get to denser air.

Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. If drag were the only concern, at any given altitude the slower you go, the less fuel you need: the work done by drag over a distance grows linearly with speed (the force grows quadratically with speed, but the time falls linearly). 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. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Make sure you have lots of control surfaces because at very high in the atmosphere, there's not much air for the wings to control the craft with. It will be expensive and time consuming. Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. There is a very close tolerance to the two speeds. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. 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 a rule of thumb they all lose thrust at higher altitudes and at high velocities. Why do small African island nations perform better than African continental nations, considering democracy and human development? probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Please consider starting a new thread rather than reviving this one. surface of jool. Or try using SRBs instead. The easiest "default" way to build a plane in KSP-- i.e. However, I've failed to build a vehicle to achieve this (without a hundred retries). Is anywhere a list of the altitude levels (I don't know a better term) available? But maybe your patience? Is it possible to get to an altitude of 16-20km with normal plane engines? I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. I've been finding it difficult to build a jet that can fly over 15km alt. 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. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. Upload or insert images from URL. - Spamming airintakes didn't help. 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. Fighting oscillations. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Typically, I watch my Apoapsis as I boost to the high altitude, and there's enough momentum to coast to the peak before completely running out of fuel. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. This is particularly useful for pairs of engines, since this makes it possible to keep the thrust equal when activating the afterburners. Only the fuel tanks attached to rockets have any oxidiser in them. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. What altitude and speed should I go? 2.) I start with the normal jet engines (which takes almost the complete runway). Reddit and its partners use cookies and similar technologies to provide you with a better experience. Pvt. (the engines will use very little at high altitude anyway). Of course, this thing has very limited range, speed and acceleration because of the extra weight. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. What are the altitudes for the various altitude record contracts? How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. I was hoping that the new intakes would give it the added altitude. I wasn't expecting so many excellent answers! Upload or insert images from URL. Also, while you mentioned the TJs most efficient altitude is ~ 5km (I'm not sure, but lets assume it's true), you need to realize that the drag you're getting at that altitude is going to wreck any efficiency gains. A little while back I spent a long time trying to circumnavigate Kerbin on the least liquid fuel possible (i posted the record to the sub: 254 units of fuel. 3x06: I design a new, high altitude, jet to collect high. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. I was generally under the impression that basic jets were mostly deadweight on high-performance aircraft: while they are superior for low-speed, low-altitude operations, they become deadweight at hypersonic velocities. You can post now and register later. i dont know what kind of range youre looking for but i would make a significantly smaller plane. That's because wings need to have some AoA to the airstream in order to generate much lift. Ep. You also need to be going very fast to generate adequate lift at high altitudes and unlike the real U-2, you don't need to fear about overspeeding and destroying the plane. This way control surface max deflection can be programmed by an aircraft designer to make . Don't worry about Isp. At sea level, it produces 120 kn thrust, but at 15 km altitude, it only produces 13.7 kn of thrust, barely enough to provide any thrust to climb higher, Long and narrow wing has less surface area to provide lift, and at higher altitude, the atmospher is so thin that the lift generated by long and narrow wings is insufficient for sustainable flight. So if you replace the turbos with basic jets, you will have more thrust from the ground up, and your vessel will weigh slightly less. My 'plane science' is more advanced than my 'rocket science' (career mode) because I got tired of seeing all the high-altitude missions I had on the books and wanted to finish them. 3x06: I design a new, high altitude, jet to collect high atmospheric science. 2022 Take-Two Interactive Software, Inc.
