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. Pvt. Personally, I don't enjoy survey contracts on Kerbin. That's all true, but just read the OP: hypersonic appears to be completely out of the question. . Kerbal Space Program - All Easter Eggs Guide Information Changelog Stats 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. Note: Your post will require moderator approval before it will be visible. Long distance airplane flight tips? - Kerbal Space Program Forums 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. Press question mark to learn the rest of the keyboard shortcuts. You can spin around the whole world on just fumes. By climbing, you reduce drag, exponentially with altitude. The best answers are voted up and rise to the top, Not the answer you're looking for? For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R.

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?). 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. 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. Cheers again fellas. No, I think it's correct, unless I've got a brain fart going, here. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. Air temperatures vary with latitude and time of day. Your previous content has been restored. 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 -. Reddit and its partners use cookies and similar technologies to provide you with a better experience. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . 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. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The U-2 is probably the highest altitude aircraft still flying. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. 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. Valve Corporation. KSP Career: Episode 13 - High Altitude Surveys - YouTube You could try combining the two. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. But since when do Kerbals wait for ideal conditions? even stranger is that the surface is textured. ksp high altitude planebad bunny tour 2022 tickets ksp high altitude plane. Welcome to the forums. 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 main body is a fuel tank with a Swivel engine at the end. 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!). How can I make money in the new career mode? 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. Turbojets are so ridiculously efficient that it doesn't really matter. So Pvt. 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. KSP - High Altitude Aircraft - YouTube Press J to jump to the feed. That would argue for going as high as possible, as slow as possible, but apart from drag you also have to fight gravity. (Actually, four ways: but balloons aren't in the stock game) Lifting surfaces are great but they lose effectiveness just as fast with altitude as drag falls. Jets drop thrust at higher altitude and speed, but also drop . Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. I start with the normal jet engines (which takes almost the complete runway). Most SSTO space planes would be able to accomplish this easily. - "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. Don't rely on the efficiency indicator! This causes the body of your plane to generate additional drag. 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. Paste as plain text instead, 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. Let me share what I know about jet engines, speed, and efficiency. Range with this method is pretty short due to drag. Any of my search term words; All of my search term words; Find results in. 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). Airplane Plus on SpaceDock Display as a link instead, These designs are great for getting around Kerbin quickly, but without going orbital. This is the first version. - Insane lift to weight didn't help. Most efficient cruise altitude for jet planes? : r/KerbalSpaceProgram Please consider starting a new thread rather than reviving this one. - "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. Best altitude to fly a plane? - Kerbal Space Program - GameFAQs 1.) Highest and fastest possible is best. Originally posted by lord bird: yep thats right jool has a surface. 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. For more information, please see our I don't have the numbers handy, but you can expect something like 400m/s at 15km. 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. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. You can do that by right-clicking the engine and clicking "Toggle Mode." You'll notice that usually your prograde marker is slightly below your pitch. 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. Simply changing the intakes made it fly completely out of control and impossible to land. Yes, although they have only been flown with nearly full tanks. Exorcet's Content - Kerbal Space Program Forums I find that a conservative amount is 2 RAM intakes and 2-4 radial intakes per turbojet. Whiplash is the engine you would want to use on a plane meant to go 20km. 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. "Whiplash" Turbojet. Aircraft can be very temperamental to fly, especially on the keyboard. Note: Your post will require moderator approval before it will be visible. Note that keeping the plane weight low is critical, only carry a very small amount of fuel. Spaceplane - Wikipedia Anyway thanks in advance. Delta-V is the velocity change necessary to perform orbital maneuvers. I wasn't expecting so many excellent answers! 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. Pasted as rich text. This thread is quite old. The high performance engine for me performs pretty good till about 15000 meter. TLDR: You need parts you don't have to make a plane that flies that high. You can post now and register later. Grichmann's answer has been the most reliable way I've found to complete these missions. 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. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Build a plane or rocket for Kerbal high altitudes - Arqade The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It's Kerbal Space Program v.22! A destructible memorial to the old Mk. Using indicator constraint with two variables, Is there a solution to add special characters from software and how to do it. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. 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. The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. These are the building blocks of solid spaceplane design!Subscribe! It seems to be based on the General Electric F-404 Afterburning Turbofan, which shares the same name and maximum thrust (85 kN dry). But maybe your patience? Upload or insert images from URL. This way control surface max deflection can be programmed by an aircraft designer to make . So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. I would like to know which altitude I have to maintain for my experiments. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. 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. This can make it a good alternative for when you want something that can be controllable and doesn't need excessive heat shielding, but still need to be able to go incredibly fast if necessary, at the expense of increased fuel consumption. You cannot paste images directly. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. http://kerbalspaceprogram.com, Press J to jump to the feed. 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. Clear editor. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. Early career high altitude observations question : r/KerbalAcademy EDIT: Didn't notice you were using FAR. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Is anywhere a list of the altitude levels (I don't know a better term) available? That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). 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. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. Don't be too surprised if KSP's aero model breaks down in edge cases. 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. You can go above 20km with the J-404 Panther. You need to do it with what you've got. My question is really about controllability. 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. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. 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. 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. 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. Once it's in the air, it's stable and easy to fly and manages to fly at altitudes between 11k 12k without problems. 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. Dedicated to the growth and advancement of amateur rocket scientists! Or is it the same for all celestial bodies? Kerbal Space Program - Wikipedia Why do many companies reject expired SSL certificates as bugs in bug bounties? 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..

Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. It may work with stock too, I just don't know. 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!]. What are the minimum altitudes for each warp level? The Kerbal Space Program subreddit. 2022 Take-Two Interactive Software, Inc. But a rockets can do it. Please consider starting a new thread rather than reviving this one. However, I've failed to build a vehicle to achieve this (without a hundred retries). This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Yes. 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 returns are diminishing so eventually you will hit a ceiling. 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. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? They will someday, but they don't now. Of course, this thing has very limited range, speed and acceleration because of the extra weight. This works, but it's not optimal. Also, Valley and Theomon fly to different corners of Kerbin and three mapping satellites are launched.

The other one I stay around 6000 meters. 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. - but they were talking about having two intakes/engine. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. with a thrust vectoring range of only 3 degrees. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! The Panther engine can hold 19,000 steady and oscillates around 20,000. Thanks. The U-2's published maximum altitude is somewhere above 74,000 feet. 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. All rights reserved. Building a High Altitude Jet | Stream pt. 2/3 (KSP 1.11.2) Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. I also added a parachute and decoupler since I find it too hard to correctly land this thing yet ;-) I managed to land in the water once, though. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Or about the same speed but 1000 m higher. 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. Let me. The most efficient way is, of course, to make a high altitude (or space) plane. 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. 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.
