with a thrust vectoring range of only 3 degrees. Cookie Notice Ksp engine altitudes : r/KerbalSpaceProgram - reddit Thank you, I was able to reach up to 24km altitude with this design. 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. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. Even up there the plane acts squirrely. High altitude planes - Kerbal Space Program Forums This way control surface max deflection can be programmed by an aircraft designer to make . 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. The easiest "default" way to build a plane in KSP-- i.e. How to know if you've nailed it perfectly: when you're cruising in level flight, you want the marker to be precisely centered in your navball cross-hairs. It is designed to aid in player-controlled flight on generic (space)plane, providing a soft layer between user joystick\keyboard input and control surface outputs. The most efficient way is, of course, to make a high altitude (or space) plane. Paste as plain text instead, A full suite of flaps on the trailing edges of the main wings give it exceptional low-speed lift, and small hydroplane steps mounted on each side of the fuselage bottom help lift it out of the water (lowering water drag) during takeoff runs. KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V and our ksp high altitude plane - digitalidentityorganization.com I didn't try for 20000m as it probably wouldn't do well. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. 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. Landing On Laythe Moon Of Jool Kerbal Space Program Youtube Here's my example of dealing with the situation. 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. Are you using Stock or NEAR/FAR? Main goals: Auto-trimming. 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. The main body is a fuel tank with a Swivel engine at the end. You are simply running out of atmosphere (i.e. 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. I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. 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. 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. Paste as plain text instead, Note that keeping the plane weight low is critical, only carry a very small amount of fuel. But since when do Kerbals wait for ideal conditions? The benefits should be obvious. This works, but it's not optimal. What am I doing wrong here in the PlotLegends specification. 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. Tutorial: Making the AI fly | BDArmory Wikia | Fandom So Pvt. 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. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. That annoys me but I can't seem to get a design to make it work. The U-2 is probably the highest altitude aircraft still flying. Anyway thanks in advance. Planes in Space. However, it seems as if your delta wing has has more area, might that be it? What's the difference between a power rail and a signal line? : : . Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) TLDR: You need parts you don't have to make a plane that flies that high. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. surface of jool. Display as a link instead, Kerbal Space Program - Wikipedia Originally posted by lord bird: yep thats right jool has a surface. Pasted as rich text. Really. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. Laythe - Kerbal Space Program Wiki I've added more engines, more intakes to no avail. I'm going to try adding a small solid fuel rocket engine toned down to get the initial height then dump it, as well as check into that high end gear mentioned. 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. Exorcet's Content - Kerbal Space Program Forums Even better, burn a little more, and you can pop out of the atmosphere for a bit and avoid all that nasty drag stuff. In KSP2, you are a rocket scientist who must build and test rockets, spaceships, and planes. You can halve the drag by climbing a bit less than 3500m. Your link has been automatically embedded. Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. 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). Clear editor. 2022 Take-Two Interactive Software, Inc. I also set it to enable the cockpit's reaction wheels to improve control at high altitude, and close air intakes to reduce drag. 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. If you've attached them to your fuselage with zero AoA, what that means is that when you fly, you're going to have to have the entire plane pitched slightly above in order to generate lift. To reach the initial low Earth orbit of the International Space Stationof 300 km (now 400 km), the delta-v is over six times higher, about 9.4 km/s. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. 600+ m/s) and low altitudes (e.g. 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. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? Minimising the environmental effects of my dyson brain, Theoretically Correct vs Practical Notation. Jet engine - Kerbal Space Program Wiki *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. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. Please consider starting a new thread rather than reviving this one. 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!). Valve Corporation. 4. Planes in Space - The Kerbal Player's Guide [Book] So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate If not, please explain why, which I know you have no problem doing! You could try combining the two. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. FAR is supposed to take aspect into account, but I'm not very experienced with it and cannot advice you as to how it works. http://kerbalspaceprogram.com, Press J to jump to the feed. What are the minimum altitudes for each warp level? The flight time won't be as long, but you'll be able to fly a "plane" above 18km. It was meant for low altitude flight. Since turbos are almost always enough to get you off the ground and up to altitude, I usually just do straight turbojets (with some RAPIERs for SSTO spaceplanes); the minute amount of fuel saved during the ascent isn't worth lugging those superfluous engines around at the hypersonic regime. Long distance airplane flight tips? - Kerbal Space Program Forums 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. Sideslip handling. Welcome to the forums, ZDW. 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. Is anywhere a list of the altitude levels (I don't know a better term) available? Highest and fastest possible is best. Pasted as rich text. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. You can post now and register later. All other versions are slower and lower and unstable in turns. The more successful the flights, the more successful the space program is. 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. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Personally, I don't enjoy survey contracts on Kerbin. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. Any of my search term words; All of my search term words; Find results in. - but they were talking about having two intakes/engine. Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. The high performance engine for me performs pretty good till about 15000 meter. Your link has been automatically embedded. Which is capable of high altitude, high speed flight. 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. This thread is quite old. 1 Pod outside the level 3 VAB. Or is it the same for all celestial bodies? So if you want to make a plane go as fast as possible, you want to minimise both angle of attack and angle of incidence necessary to sustain level flight at your target speed and altitude. Now lets combine these two indicators: The best performance your engine can achieve is when you have an optimal amount of Air Flow (obviously) but also the MAXIMUM amount of Air Intake. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. The thrust of jets (turbo or otherwise) depends on airspeed: basics deliver more thrust at low speeds, while turbojets only really come into their own when you fly very fast (which also means flying very high, 20km and over). Information Changelog Stats Don't rely on the efficiency indicator! What are the units of measure used in Kerbal Space Program? Do plugins for Kerbal Space Program work on unix? As high and fast as you can go without engine flameout: preferably ~2000 m/s at 25-30 km (and yes, that's almost orbital velocity). EDIT: Didn't notice you were using FAR. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Redoing the align environment with a specific formatting, Trying to understand how to get this basic Fourier Series. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. At this point the plane plummets, but as it goes deeper into the atmosphere, it regains pitch authority, and at 10km it's enough to regain control and turn it around for a safe landing. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). KSP Career: Episode 13 - High Altitude Surveys - YouTube You can go above 20km with the J-404 Panther. All rights reserved. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. I'm trying to build a high altitude plane and have found out that the rules are different. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). (the engines will use very little at high altitude anyway). Unfortunately, there's no simple rule to tell you what the angle needs to be when you're building the plane-- it depends on lots of variables, such as your weight, drag, intended cruising altitude, intended cruising speed. However, I've failed to build a vehicle to achieve this (without a hundred retries). That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. How can this new ban on drag possibly be considered constitutional? First is thrust; the higher you get, the lower the thrust your engines deliver. They will someday, but they don't now. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. Create an account to follow your favorite communities and start taking part in conversations. even stranger is that the surface is textured. It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). When added to a plane it allows tuning of the controls vs speed/altitude/G load/other factors. 20 votes, 21 comments. 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. Then I increase throttle until about 2/3 or even full, climbing with a high inclination (it can also go straight up). Challenges Have you checked out the wiki yet? Isn't that backwards snark? Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. With only panthers unlocked I might add. At 3500m, you have half the drag you'd have at the surface; at 7km, 1/4 the drag, at 10.5km, 1/8 the drag, etc. AoA and G-force moderation. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Planes and Altitude differences. :: Kerbal Space Program General Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . Why is there a voltage on my HDMI and coaxial cables? I've since shaved that down more but that was by going even higher and even faster). Rockets aren t the only way to get to space. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Steam Workshop::damn wow Beginner's Guide: Tips and Basics - Kerbal Space Program 2 Wiki Guide - IGN Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. - Spamming airintakes didn't help. (Disclaimer: I've never used FAR myself; all of the above is based on my experience with stock aerodynamics. Powered by Invision Community. Your airspeed is mostly limited by terminal velocity; you can go much faster if you climb a little higher.

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). List of altitude levels? - Forums - Kerbal Space Program Forums But maybe your patience? 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. a screenshot of kerbal space program 2. by: lord bird. Clear editor. 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? Press J to jump to the feed. But. 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. Grichmann's answer has been the most reliable way I've found to complete these missions. 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. When you are surrounded by plenty of air there will of course be no need to suck in air artificially but the higher you get the less dense the air around you becomes and in order to make sure that your engines have enough oxygen to burn the fuel it needs to suck air in forcefully. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. It may work with stock too, I just don't know. That's because wings need to have some AoA to the airstream in order to generate much lift. Building a rocket to fly vertical seems to be nearly impossible, in the atmosphere they tend to become unstable (or maybe I missed a trick?). Chapter 4. There is a very close tolerance to the two speeds. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.
