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. 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. You get tons of thrust if you put it into "wet" mode, but you lose fuel efficiency. 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. What's the difference between a power rail and a signal line? Make sure you've angled your wings up slightly so that you provide enough lift for a 0 angle of attack at top speed. Hello there. This is my current best hi alt plane. You cannot paste images directly. 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.

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. Double your speed, you need twice as much fuel. 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. As you found out, it basically konks out at 15km. 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. But you'll need to unlock: High Altitude Flight Which cost 300 science. 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.

In the main KSP settings menu you should set the default throttle to 1.0 (technically the above mechjeb setting winds up restoring the default throttle, so it needs to be 1.0) In the attitude adjustment menu make sure you are using the "better controller" Whack the 45 degree phase margin button Whack the restore all other defaults button Don't rely on the efficiency indicator! To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You do get certain inertial and lever-arm effects, but those aren't really relevant to 'do I have enough lift to stay up'. KSP doesn't care (much) about aspect ratio; the total lift is the same regardless of configuration. The main body is a fuel tank with a Swivel engine at the end. 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." I looked into the .cfg files and there are no special properties allocated to them. How do I install mods for Kerbal Space Program 1.1? Note that you need to activate the afterburner ("Wet Mode") manually. Even if the air is thin, you can still put out plenty of power if you are shoving enough in with raw speed.

But my guess is that these same general principles would probably apply to FAR, and that all that would change would be the numbers involved. You will find that when you're flying around, will always be slightly below the crosshairs on the navball. TLDR: You need parts you don't have to make a plane that flies that high. 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). You can post now and register later. I got this game so I could over-engineer rockets, so I mostly ignore the airplanes. Kerbal Space Program 2 . Please consider starting a new thread rather than reviving this one. Personally, I don't enjoy survey contracts on Kerbin. Remember that you need to have intakes somewhere in line with the engine to function at that altitude. 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. I followed a similar strategy. You can post now and register later. You can go above 20km with the J-404 Panther. Your previous content has been restored. 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.

There is no such thing as "so high radar can not detect it", since radar can detect things in outer space. I should perhaps start trying out NEAR to get ready of 0.90, though.

However, I've failed to build a vehicle to achieve this (without a hundred retries). So, to correct " is below crosshairs", what you need to do is to add a little AoA to the wings. Sustained flight at over 20km requires at a minimum the Panther in Afterburning mode. Pasted as rich text. 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 Each stage of the rocket has a delta-v that depends on the stage fuel mass and the engine specific impulse. It only takes a minute to sign up. (the engines will use very little at high altitude anyway). There are two factors to that: how thick the air is, how fast the ship is going. Air Intake) and how fast your aircraft ultimately flies (air resistance/altitude)! You'll notice that usually your prograde marker is slightly below your pitch. 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 U-2 is probably the highest altitude aircraft still flying. 20 votes, 21 comments.

Planes in Space. What you should be concerned about is atmospheric drag, and that's minimized by high-altitude flight. More air is better. Designing a High Altitude Jet | KSP: Making Space Home Mike Aben 24.8K subscribers Join Subscribe 85 Share 3.4K views 1 year ago Ep. In my case, it brought me to 20km up at a 45-degree angle, but it is probably not optimal. Slap that behind a plane you'll be able to go beyond 20km without any trouble. This causes the body of your plane to generate additional drag. probably the easiest place to land in the system as terminal velocity is survivable for a craft less kerman. if you just go into the SPH, slap together some parts like Legos, and go-- is to attach them with zero AoA. I tried building a plane but can't climb higher than about 11,000m (I don't have many plane parts yet, though). Simply changing the intakes made it fly completely out of control and impossible to land. You arent doing anything wrong. 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.

Display as a link instead, I only seem to be able to make planes that can fly a bit below that altitude and then temporary rise to it. Press J to jump to the feed. Air Intake: Air Intake shows the amount of force your engine uses to suck air into the turbine. For more information, please see our AoA itself refers to the angle of the wing (or the whole plane if the AoI is 0)relative to the airflow. jet engine efficiency in this game is based on built in thrust curves. 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. In the game, players direct a nascent space program, staffed and crewed by green humanoid aliens known as "Kerbals". 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.

You can spin around the whole world on just fumes. Don't be too surprised if KSP's aero model breaks down in edge cases. Ok, the panther engine is still not good enough. Which lets you go faster, which lets you climb higher. The longest flight got them down to a little more than half full. I've added more engines, more intakes to no avail. 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. 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. At altitude the nose goes up and down until it goes out of control. This tutorial will cover designing and flying a plane that can soar at high altitudes! Clear editor. This way control surface max deflection can be programmed by an aircraft designer to make . 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. My plane has turbojets and lots of fuel, but I am wondering what the optimal way to fly is. Because of the exponential nature of the rocket equationthe orbital rocket needs to be considerably bigger. The idea is to slow the plane to a stall above your landing spot the pop the parachute. Remembering the FW TA152 and the U2 I put long wings on it and while its turn rate makes an airliner look like a fighter plane it is stable enough at 19000m. Dedicated to the growth and advancement of amateur rocket scientists! You are just about at maximum speed and at the same time very close to stall speed. This can be done with moar boosters or more calculated wing and body design, depending on the aero model you use. 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.

The most efficient way is, of course, to make a high altitude (or space) plane. Under some circumstances, you may want to reduce the engine gimbal range or disable it altogether, particularly when flying at high speeds (e.g. Yes. 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.

That's all true, but just read the OP: hypersonic appears to be completely out of the question. even stranger is that the surface is textured.

I am currently designing a mission that will involve several very long distance plane flights. All other versions are slower and lower and unstable in turns. From my experience using a panther it starts to lose speed after 15-16 kms, a more suitable cruising height is 9-13km. Don't worry about Isp. A destructible memorial to the old Mk. Check out the website and try the game out for yourself :Dhttps://kerbalspaceprogram.com/ below 5,000 m), since the engine's extreme maneuverability may allow the aircraft to perform turns sharply enough to break up in flight. 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. Information Changelog Stats Keep in mind that wheesley engine's performance decreases significantly as the altitude increases. You are simply running out of atmosphere (i.e. There is a very close tolerance to the two speeds. 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
