ksp high altitude plane
below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Yes, although they have only been flown with nearly full tanks. There are two factors to that: how thick the air is, how fast the ship is going. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? 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. ksp high altitude plane. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. air) that high up. I'm trying to build a high altitude plane and have found out that the rules are different. These are the building blocks of solid spaceplane design!Subscribe! 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. This tutorial will cover designing and flying a plane that can soar at high altitudes! Imagine that first plane but with the bubble cockpit and the old style round intakes. Main goals: Auto-trimming. Fighting oscillations. Let me share what I know about jet engines, speed, and efficiency. Yes. 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. Hopefully this will be helpful to you. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. That will unlock: All trademarks are property of their respective owners in the US and other countries. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Paste as plain text instead, It'll probably be more efficient with more intakes, but I wouldn't increase the number of engines. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Thats my problem right now. The returns are diminishing so eventually you will hit a ceiling. By climbing, you reduce drag, exponentially with altitude. 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?

Please consider starting a new thread rather than reviving this one. Which is capable of high altitude, high speed flight. Delta wings are able to work better since the lack of lift per square area is compensated by having larger area to provide lift. Building a High Altitude Jet | Stream pt. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. Press question mark to learn the rest of the keyboard shortcuts. Basically I can hit a target altitude of 20,000m but can not maintain it. Chapter 4. The high performance engine for me performs pretty good till about 15000 meter. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. 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. surface of jool. No, I think it's correct, unless I've got a brain fart going, here. Basically there are two things that limit your maximum speed: thrust and speed of sound and with that your maximum altitude. Rockets aren t the only way to get to space. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. Cheers again fellas. Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. The SR-71 could probably fly higher, but it isn't flying any more. 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. But you'll need to unlock: High Altitude Flight Which cost 300 science. You can post now and register later. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. 600+ m/s) and low altitudes (e.g. Or about the same speed but 1000 m higher. 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. That's sub-optimal, because having the fuselage pitched like that means it'll have more drag than it otherwise would have.

Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. 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 Watch out for your SAS if you're running batteries without a jet for a long time. 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. 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. That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. 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. The most obvious solution is try and optimize your craft for high altitude lift by giving it long wingspan like a U-2 spyplane. I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. I currently have a contract where I'm asked to take crew reports at certain spots on Kerbal at an altitude of 18,000m. its rather flat but its a solid surface. All rights reserved. I've since shaved that down more but that was by going even higher and even faster). 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). Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. Why do many companies reject expired SSL certificates as bugs in bug bounties? You arent doing anything wrong. Maneuver node plans don't take drag into account, so you'll have to overshoot quite a bit to compensate. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! - Spamming airintakes didn't help. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. Is there a single-word adjective for "having exceptionally strong moral principles"? 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. Trying to do something without the right part is long and difficult path. 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. Listen to this guy, don't go much farther above 15000 with high altitude engines. 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." 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. Should i add a larger wing area for higher lift? 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. I have enough patience to do the slow flying, but is it horribly inefficient? This causes the body of your plane to generate additional drag. 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. For example, the RAPIER engine doesn't seem as the first choice as the "best" high altitude air-breathing engine but in long-distance and high-altitude challenges it is. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. If you upgrade to the panther (or get one on a contract) that engine can get you much higher. June 3, 2022 . and our Welcome to the forums, ZDW. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). 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)? You can spin around the whole world on just fumes. 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. Pasted as rich text. This page was last edited on 22 December 2019, at 20:54. Is it suspicious or odd to stand by the gate of a GA airport watching the planes? To get higher with the low tech jet engines, you need rocket assist. - "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. The easiest "default" way to build a plane in KSP-- i.e. Powered by Invision Community. 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 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. This works, but it's not optimal. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. 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. 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. You cannot paste images directly. 2022 Take-Two Interactive Software, Inc. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Mounting a time-limited rescue mission for kerbal inbound to Kerbin. Welcome to the forums. That annoys me but I can't seem to get a design to make it work. 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. I wasn't expecting so many excellent answers! Thanks for the help! What's the difference between a power rail and a signal line? If you have an account, sign in now to post with your account. Yes. 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. 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. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. 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. Very cool. Paste as plain text instead, That's all true, but just read the OP: hypersonic appears to be completely out of the question. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. This makes jets built using this engine considerably more maneuverable. 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. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". Pretty often, the tail "wiggled" and/or the plane became totally unstable when I fired the rocket boosters. You are simply running out of atmosphere (i.e. This thread is quite old. The most efficient way is, of course, to make a high altitude (or space) plane. 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. 2022 Take-Two Interactive Software, Inc. 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. As said above, the Wheesley is specifically designed as a low altitude engine. Or try using SRBs instead. 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. Ok, the panther engine is still not good enough. AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. 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. high-2 A Screenshot of Kerbal Space Program principle. Will post my results. FBW uses three controllers - pitch, roll and yaw. Don't worry about Isp. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). How to tell which packages are held back due to phased updates. 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. Pasted as rich text. What are the altitudes for the various altitude record contracts? If released at a speed of 700 or more m/s and an altitude of 20 or more km, the satellite will achieve orbit with its second stage mostly full, leaving it with approximately 1600 m/s of delta-V -- enough to achieve lunar or interplanetary orbits and, on small bodies, landings. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. Isn't that backwards snark? 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. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. Why do small African island nations perform better than African continental nations, considering democracy and human development? 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. 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. KSP also tends to have very harsh induced drag if angle of attack gets too high. Thanks for asking this, I've been struggling with the same problem in career mode. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Note that you need to activate the afterburner ("Wet Mode") manually. The maximum cruise altitude is just over 40,000 feet. - but they were talking about having two intakes/engine. The most efficient way is, of course, to make a high altitude (or space) plane. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Do plugins for Kerbal Space Program work on unix?
