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. I don't have that cockpit in my career game yet, but maybe it will work with the other one. below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. The U-2's published maximum altitude is somewhere above 74,000 feet. Display as a link instead, Basically I can hit a target altitude of 20,000m but can not maintain it. 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). 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. I also had problems with a high altitude plane until I decided to follow the K.I.S.S. Either of the two speeds are to be avoided. Aircraft can be very temperamental to fly, especially on the keyboard. Personally, I don't enjoy survey contracts on Kerbin. Grichman's answer got me in the right direction. That will probably allow you to fly comfortably above 20-25km (or higher, depending on the overall mass of your aircraft). Editing Kerbal Space Program save files for KSO, Rasterpropmonitor for Kerbal Space Program. 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. Clear editor. 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. high-1 A Screenshot of Kerbal Space Program By: miklkit This is the current version. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. Display as a link instead, 3x06: I design a new, high altitude, jet to collect high atmospheric science. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. . For more information, please see our This page was last edited on 22 December 2019, at 20:54. Air Intake) and how fast your aircraft ultimately flies (air resistance/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 -. Learn more about Stack Overflow the company, and our products. Why that? Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. 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). Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. There are no requirements as far as size or power are concerned, as the AI Pilot is capable of flying pretty much anything - from tiny scout planes to oversized freight craft. 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. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. In the stock atmosphere, the benefits of moving faster outweigh almost everything else. 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. 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. They will someday, but they don't now. Unfortunately I won't be able to test it today, but @SaintWacko's proposal sounds promising. Alternatively, you can assign the afterburner toggle (labelled "switch mode") to an action group if you wish to activate it with a hotkey. This is my current best hi alt plane. 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. at the very least, you'd need the panther, that'll get you over 16k easily, well to 25k. It only takes a minute to sign up. Yes. 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. So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. Pvt. Powered by Invision Community. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. General Electric F-404 Afterburning Turbofan, Stratus-V Cylindrified Monopropellant Tank, Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine, LFB KR-1x2 "Twin-Boar" Liquid Fuel Engine, T-1 Toroidal Aerospike "Dart" Liquid Fuel Engine, S1 SRB-KD25k "Kickback" Solid Fuel Booster, IX-6315 "Dawn" Electric Propulsion System, AE-FF1 Airstream Protective Shell (1.25m), AE-FF3 Airstream Protective Shell (3.75m), PB-NUK Radioisotope Thermoelectric Generator, https://wiki.kerbalspaceprogram.com/index.php?title=J-404_%22Panther%22_Afterburning_Turbofan&oldid=95515. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. its rather flat but its a solid surface. http://kerbalspaceprogram.com, Press J to jump to the feed. The most efficient way is, of course, to make a high altitude (or space) plane. Its an approximation missing someelements. 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. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. Most SSTO space planes would be able to accomplish this easily. The Panther engine can hold 19,000 steady and oscillates around 20,000. Be aware that heat buildup can gradually become a problem when the afterburners are used in sustained flight. This makes jets built using this engine considerably more maneuverable. Air Flow + max. air) that high up. Is there a single-word adjective for "having exceptionally strong moral principles"? - Insane TWR didn't help. Should i add a larger wing area for higher lift? : : . If you have an account, sign in now to post with your account. As long as the engine gets enough air it will work at proper efficiency. Anyway thanks in advance. The Kerbal Space Program subreddit. Let me share what I know about jet engines, speed, and efficiency. What's the difference between a power rail and a signal line? This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Here's Mr. Manley using it in his tutorial: @Pvt.Grichmann: I think it's at specific locations on Kerbin, not just anywhere above 18km. I start with the normal jet engines (which takes almost the complete runway). Unfortunately, most space plane designs are impossible (or at the very least impractical) at your current tech level. and our Don't worry about Isp. 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. Clear editor. So the faster you go the higher you can fly where there is less drag. Hello there. I have enough patience to do the slow flying, but is it horribly inefficient? if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. 2022 Take-Two Interactive Software, Inc. The stratospheric region, where temperature rises as altitude increases, spans the region between the altitudes of 10 km and 22 km. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Use the reaction wheel to hold your attitude slightly nose down as you float down and you can guide yourself like a paraglider. - "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. First off as of .15.1 intakes don't do anything. You can go above 20km with the J-404 Panther. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Put a couple of radial mount parachutes just above the com and add a reaction wheel. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. With only panthers unlocked I might add. These are the building blocks of solid spaceplane design!Subscribe! Content titles and body; Content titles only Or is it the same for all celestial bodies? The maximum cruise altitude is just over 40,000 feet. 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. Note: Your post will require moderator approval before it will be visible. You can halve the drag by climbing a bit less than 3500m. Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. 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. It is stable but can not maintain altitude. What are the altitudes for the various altitude record contracts? For comparison, the second most maneuverable engine is the CR-7 R.A.P.I.E.R. I generally don't fuss with AoI unless I'm making a long range cruiser. I've since shaved that down more but that was by going even higher and even faster). 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 may be correct and that 3 engine plane is a lemon. Though I'm still working on learning to be better at space planes. Note that you need to activate the afterburner ("Wet Mode") manually. high-2 A Screenshot of Kerbal Space Program Any of my search term words; All of my search term words; Find results in. But maybe your patience? It flames out at 25,000. Is it correct to use "the" before "materials used in making buildings are"? Cookie Notice AoA and G-force moderation. i recently used a single whiplash plane and was able to maintain a stable 21-22k meter altitude. When I say ", You know you've nailed it correctly if, when you're in level flight, your. Air temperatures vary with latitude and time of day. Very cool. Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . What are the minimum altitudes for each warp level? 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. Trying to do something without the right part is long and difficult path. Simply changing the intakes made it fly completely out of control and impossible to land. The flight time won't be as long, but you'll be able to fly a "plane" above 18km. Press question mark to learn the rest of the keyboard shortcuts. 2022 Take-Two Interactive Software, Inc. Make sure we're on the same page with terminology. 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. 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. Watch out for your SAS if you're running batteries without a jet for a long time. That's all true, but just read the OP: hypersonic appears to be completely out of the question. 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!]. 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. Paste as plain text instead, Thankyou all, I now reckon I have a much better understanding of the engines, hopefully that'll translate to better aircraft. But you'll need to unlock: High Altitude Flight Which cost 300 science. How do I align things in the following tabular environment? Additionally please know that .16 will feature new code that will change the way space planes work in every aspect. From my observations I can say that "Efficiency" is not a good indicator of how well your engine performs. Paste as plain text instead, Please consider starting a new thread rather than reviving this one. 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 You will find that when you're flying around, will always be slightly below the crosshairs on the navball. Clear editor. Display as a link instead, KSP also tends to have very harsh induced drag if angle of attack gets too high. - "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. Secondly don't think of engines working better at different altitudes, think of them working better with different air intake quantities. Press J to jump to the feed. How can this new ban on drag possibly be considered constitutional? AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. Kerbal Space Program 2 . But a rockets can do it. Your link has been automatically embedded. Rockets aren t the only way to get to space. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. 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. Which makes this engine ideal for those missions which require doing many science activities above particular altitudes. 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. 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. Ok, the panther engine is still not good enough. Proceed with caution. 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. If too much air runs into the turbine, the excessive amount just flows out unused through side-vents (I think). The Rapier, for example, works great as a high-altitude engine, precisely because it can go so fast. But. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. 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. 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." alternatively, combine a liquid fuel rocket into your plane. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. Upload or insert images from URL. - Insane lift to weight didn't help. There is a very close tolerance to the two speeds. Will post my results. Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts.
