AoA built into the wing relative to the plane body is called the angle of incidence, just to help clear up. 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. At the equator, sea level temperatures vary between a nighttime low of 9 C and a daytime high of 15 C. 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. Anyway thanks in advance. 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. Welcome to the forums. 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?

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. "Whiplash" Turbojet. How do I align things in the following tabular environment? 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). Create an account to follow your favorite communities and start taking part in conversations. FBW uses three controllers - pitch, roll and yaw. and our That would oscillate slowly between 16000m and 17000m but was otherwise fully controllable. Well, this game isn't a perfect flight simulator yet, so it will be difficult to figure out. Only the fuel tanks attached to rockets have any oxidiser in them. Planes in Space. Most SSTO space planes would be able to accomplish this easily. 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. EDIT: Didn't notice you were using FAR. I've been finding it difficult to build a jet that can fly over 15km alt. They will someday, but they don't now. Is it possible to get to an altitude of 16-20km with normal plane engines? So Pvt. 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. However, it seems as if your delta wing has has more area, might that be it? Here's my example of dealing with the situation. Trying to do something without the right part is long and difficult path. - "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. Create an account to follow your favorite communities and start taking part in conversations. If it's above the cross-hairs, you need a little less. Let me. Privacy Policy. The Inland Kerbal Space Center itself, being in effect the old Kerbal Space Center from 0.2. Once you're at that regime, you should be able to cover huge distances on tiny amounts of fuel. You can spin around the whole world on just fumes. I didn't succeed with his design, though; I always ended up having somehow unstable airplanes. She has a horrible turn rate and oscillates a couple of thousand meters at cruise, but it's flyable. Is it correct to use "the" before "materials used in making buildings are"? As long a you can fly faster, the lower density at altitude can be compensated for. What am I doing wrong here in the PlotLegends specification. As you found out, it basically konks out at 15km. Do plugins for Kerbal Space Program work on unix? The main body is a fuel tank with a Swivel engine at the end. The U-2 is probably the highest altitude aircraft still flying. 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. In this chapter, you ll learn about the Space Plane Hangar, a building that forms part of the Kerbal . I'm in career mode (have the turbofan engine) and trying to get some science readings for a mission at a high altitude. Note: Your post will require moderator approval before it will be visible. How to make a loop for linear actuator in Kerbal Space Program, Breaking Ground. 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 . Air temperatures vary with latitude and time of day. as a rule of thumb they all lose thrust at higher altitudes and at high velocities. Thats my problem right now. Your engine burns the same amount of jetfuel per second regardless of how high or fast you are! Along with rockets, planes are one of KSP's most commonly referenced kinds of vessel, and are a vessel type . This thread is quite old. Running the 60U engine at about 40U seems to give me a good balance between reduced drag and air intake. 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. Slap that behind a plane you'll be able to go beyond 20km without any trouble. Then it is "In Space Low over Mun.". The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. Pasted as rich text. Slap that behind a plane you'll be able to go beyond 20km without any trouble. 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." Either of the two speeds are to be avoided. Technically, any rocket engine is also a jet engine as it forms a high-speed jet of reaction mass. Best way to get down into thicker air and land is to perform what dogfighters called a 'Split-S'. - but they were talking about having two intakes/engine. You can post now and register later. Welcome to the forums, ZDW. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. That's just a guess, though-- perhaps someone more familiar with FAR could weigh in.). 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. So I'm pretty darn new to KSP, and my career has barely gotten started, and the jobs for crew observations seem to dominate Cheers again fellas. Because when your engine has to take in air forcefully it automatically means there isn't enough surrounding your engine and that again means that air density and therefor air resistance must be pretty low too. Arqade is a question and answer site for passionate videogamers on all platforms. How can I make money in the new career mode? Paste as plain text instead, I don't have that cockpit in my career game yet, but maybe it will work with the other one. 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. Have a plane that ditches its wings and rockets up to 18km once you reach the right point. 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. For all your gaming related, space exploration needs. As has been said, ISP is nothing to worry about. jet engine efficiency in this game is based on built in thrust curves. I would like to know which altitude I have to maintain for my experiments. Press J to jump to the feed. How do I install mods for Kerbal Space Program 1.1? More air is better. Did any DOS compatibility layers exist for any UNIX-like systems before DOS started to become outmoded? AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. And it's stock, unfortunately. Due to the lower air pressure at higher altitudes its thrust output decreases accordingly. What are the units of measure used in Kerbal Space Program? Have you checked out the wiki yet? Yes. They always seem to lose power at about 15km, but I'm wondering if there's something I can do to fix that. Don't rely on the efficiency indicator! To subscribe to this RSS feed, copy and paste this URL into your RSS reader. principle. 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. The more successful the flights, the more successful the space program is. 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. i dont know what kind of range youre looking for but i would make a significantly smaller plane. Approximately 12km up the main engines stop providing enough thrust to maintain the climb, so it's time to switch to rocket mode. Watch out for your SAS if you're running batteries without a jet for a long time. How can this new ban on drag possibly be considered constitutional? This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. Proceed with caution. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. Press question mark to learn the rest of the keyboard shortcuts. Please consider starting a new thread rather than reviving this one. At altitude the nose goes up and down until it goes out of control. 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 should perhaps start trying out NEAR to get ready of 0.90, though. 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 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. At about 400-500m/s (~15km), the two engines are even. Your answer got me in the right direction, though I ended up with a different design (see my own answer). But since when do Kerbals wait for ideal conditions? The X-37 is operated by the United States Space Force for orbital spaceflight missions intended to demonstrate reusable space technologies. Are you using Stock or NEAR/FAR? 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). Main goals: Auto-trimming. rev2023.3.3.43278. 1.) 600+ m/s) and low altitudes (e.g. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. There is no such thing as "so high radar can not detect it", since radar can detect things in outer space.
