Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. The U-2 is probably the highest altitude aircraft still flying. Put a couple of radial mount parachutes just above the com and add a reaction wheel. 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!). You can post now and register later. With only panthers unlocked I might add. By climbing, you reduce drag, exponentially with altitude. 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. 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. 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. Ep. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency.
Airplane Plus on SpaceDock Only the fuel tanks attached to rockets have any oxidiser in them.
KSP Delta-V Calculator - KSP HOW TO CALCULATE DELTA-V Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. 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. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? 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. The J-404 "Panther" Afterburning Turbofan is a jet engine added in version 1.0.5. *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. Yes, although they have only been flown with nearly full tanks. . Or is it the same for all celestial bodies? Let me. Please consider starting a new thread rather than reviving this one. 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. Your previous content has been restored. New comments cannot be posted and votes cannot be cast. And how many km can I expect to get per v (as calculated by Engineer redux Kerbin atmospheric stats, I know this is weird with planes)? So I've created those two planes, both with weasley turbofan engine: This is your problem-- as folks have pointed out, it's not a high-altitude engine. 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. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Planes in Space. The SR-71 could probably fly higher, but it isn't flying any more. Why is there a voltage on my HDMI and coaxial cables? 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. Basically you just need to fiddle with it and try some test flights. Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. You are just about at maximum speed and at the same time very close to stall speed.
As you found out, it basically konks out at 15km. What are the altitudes for the various altitude record contracts? So the faster you go the higher you can fly where there is less drag. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. These designs are great for getting around Kerbin quickly, but without going orbital. This tutorial will cover designing and flying a plane that can soar at high altitudes! Note: Your post will require moderator approval before it will be visible. 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. 1Altitude requirement 2Orbit 3Speed, range, and altitude 4Flight duration 5Flight profiles 5.1Ballistic missiles 5.2Tourist flights 5.3Scientific experiments 5.4Sub-orbital transportation 6Notable uncrewed sub-orbital spaceflights 7Crewed sub-orbital spaceflights 8Future of crewed sub-orbital spaceflight 9See also 10References Is it even possible?
TroubleshootingMechJebPVG - KSP-RO/RP-0 GitHub Wiki even stranger is that the surface is textured. 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. That annoys me but I can't seem to get a design to make it work. 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. 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. Why do small African island nations perform better than African continental nations, considering democracy and human development? The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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!]. The high performance engine for me performs pretty good till about 15000 meter. If it's below the cross-hairs, you need a little more AoA. You can post now and register later. 20 votes, 21 comments. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. You arent doing anything wrong. Display as a link instead, No, I think it's correct, unless I've got a brain fart going, here. The U-2's published maximum altitude is somewhere above 74,000 feet. 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). But you'll need to unlock: Which cost 300 science. 600+ m/s) and low altitudes (e.g. 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. You cannot paste images directly. Don't rely on the efficiency indicator! Slap that behind a plane you'll be able to go beyond 20km without any trouble.
Plane - Kerbal Space Program Wiki 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? Your previous content has been restored.
Jet engine - Kerbal Space Program Wiki To get there, you're going to want to climb at the fastest rate you can manage to 18-20 km, at which point you should mostly level off and start accelerating horizontally. You can spin around the whole world on just fumes. Highest and fastest possible is best.
Does a plane consume more fuel if it flies at higher altitudes? The longest flight got them down to a little more than half full.
GitHub - Boris-Barboris/AtmosphereAutopilot: Plugin for Kerbal Space Is there a single-word adjective for "having exceptionally strong moral principles"? Yes. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Thats my problem right now. 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. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. How can I make money in the new career mode?
Exorcet's Content - Kerbal Space Program Forums 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. - Insane TWR didn't help. The ideal case for optimally efficient flight (which is what you want if you're trying to maximize cruise altitude) is when your wings are mounted to the body, pitched up just enough that when cruising in level flight, the body of the aircraft is pointing perfectly . It may work with stock too, I just don't know. Which lets you go faster, which lets you climb higher.
KSP Quick Guides: High Altitude Design and Flying - Stock v.23 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. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Ksp engine altitudes I've been trying my hand at some High altitude speedy planes for a while now, but can't seem to get a hang of the altitudes that each engine likes, I know kerbal isn't earth, so looking up the crushing altitude of say the sr71, doesn't seem to apply, but I was hoping that others experiences would help me. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Or about the same speed but 1000 m higher. http://kerbalspaceprogram.com, Press J to jump to the feed.
Best altitude to fly a plane? - Kerbal Space Program - GameFAQs Here's my example of dealing with the situation. Or try using SRBs instead. Display as a link instead, Thanks for asking this, I've been struggling with the same problem in career mode. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. 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. Fighting oscillations. Really. Should i add a larger wing area for higher lift? If you upgrade to the panther (or get one on a contract) that engine can get you much higher. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. The Kerbal Space Program subreddit. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. It is stable but can not maintain altitude.
CONTROLABLE plane for ~20km altitude? :: Kerbal Space Program General Since gravity is effectively lower, they don't need as much wing area to maintain altitude-- which, in turn, means less drag, which makes for more efficient flight.

To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The most efficient way is, of course, to make a high altitude (or space) plane.
KSP Career: Episode 13 - High Altitude Surveys - YouTube 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. 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. 2022 Take-Two Interactive Software, Inc. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Can't remember where I saw/read about it - Scott Manley maybe? Air Flow + max. Basically I can hit a target altitude of 20,000m but can not maintain it. Why that? 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." But you'll need to unlock: High Altitude Flight Which cost 300 science. Or it can supercruise at three times the speed of an equivalent Wheesley jet (with nearly equal fuel efficiency) at 15,000 m altitude.
Sub-orbital spaceflight - Wikipedia So Pvt. One of my planes is small and agile, and can easily enough glide to a safe landing even if the rockets consume all the fuel. Create an account to follow your favorite communities and start taking part in conversations. This is the first version. lost birth certificate near berlin; ksp high altitude plane. If too little air runs into the turbine your combustion chamber will not be able to burn up fuel effectively due to the lack of oxygen. There is a very close tolerance to the two speeds. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Let me share what I know about jet engines, speed, and efficiency. Aircraft can be very temperamental to fly, especially on the keyboard. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Any of my search term words; All of my search term words; Find results in. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). Ok, the panther engine is still not good enough. The most efficient way is, of course, to make a high altitude (or space) plane.
Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram Ideally, you'll want to avoid these contracts until you get the High-Altitude Flight tech node and the improved jet engine that comes with it. 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. 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 Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. The returns are diminishing so eventually you will hit a ceiling.
KSP - High Altitude Aircraft - YouTube Please consider starting a new thread rather than reviving this one. You could try combining the two. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. The sweet spot for the upper atmo engines, I find, is between 10k and 12k.

I checked the wiki before I wrote my question, it seems I overread this paragraph Something that I think has become less clear since someone updated the wiki. This thread is quite old. Don't worry about Isp. Press question mark to learn the rest of the keyboard shortcuts. A well-designed jet with this engine and with the afterburner lit, flown properly, can momentarily climb to 30,000 m altitude. Please consider starting a new thread rather than reviving this one. 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? 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. Welcome to the forums, ZDW. Range with this method is pretty short due to drag. Reddit and its partners use cookies and similar technologies to provide you with a better experience. All other versions are slower and lower and unstable in turns. You may be correct and that 3 engine plane is a lemon. Pvt. Using Kolmogorov complexity to measure difficulty of problems? I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. To avoid running out of fuel altogether, I have a second plane with small tanks (no oxidizer) attached directly to the jet engines, and the rockets attached behind the fuselage, which is entirely oxidized tanks. When I say ", You know you've nailed it correctly if, when you're in level flight, your. If not, please explain why, which I know you have no problem doing! Strictly speaking this optimisation is unnecessary, but it can win you a bit of range. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km.
I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. That will unlock: "Whiplash" Turbojet Which is capable of high altitude, high speed flight. AoA and G-force moderation. Delta-V is the velocity change necessary to perform orbital maneuvers. I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. That will unlock: I've added more engines, more intakes to no avail. Why do many companies reject expired SSL certificates as bugs in bug bounties? You can post now and register later. To get higher with the low tech jet engines, you need rocket assist. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. Is it correct to use "the" before "materials used in making buildings are"? Sideslip handling. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. You can go above 20km with the J-404 Panther. I'm trying to build a high altitude plane and have found out that the rules are different. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. You can do that by right-clicking the engine and clicking "Toggle Mode." Cookie Notice Rockets aren t the only way to get to space. - Spamming airintakes didn't help. rev2023.3.3.43278. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. It was meant for low altitude flight.
List of altitude levels? - Forums - Kerbal Space Program Forums Then it is "In Space Low over Mun.". Cheers again fellas. Grichmann's answer has been the most reliable way I've found to complete these missions. 1.) I have enough patience to do the slow flying, but is it horribly inefficient? i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. 2022 Take-Two Interactive Software, Inc. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. jet engine efficiency in this game is based on built in thrust curves. 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. It is somewhat slow but very steady in flight. You can halve the drag by climbing a bit less than 3500m. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! If you have an account, sign in now to post with your account. 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.. Visit Stack Exchange As long as the engine gets enough air it will work at proper efficiency. Dedicated to the growth and advancement of amateur rocket scientists! The benefits should be obvious. I am currently designing a mission that will involve several very long distance plane flights. What am I doing wrong here in the PlotLegends specification. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. Listen to this guy, don't go much farther above 15000 with high altitude engines. Of course, this thing has very limited range, speed and acceleration because of the extra weight. "Whiplash" Turbojet. Very cool. Powered by Invision Community. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable.
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.
Landing On Laythe Moon Of Jool Kerbal Space Program Youtube 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 I'm near or in the target area, I set the throttle to 0 and start the Swivel. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.
