They have done something to some wheels and landing gear that makes them oscillate. The LY-01 fixed gear will not stop bouncing. There is also something different about flying.

AngrybobH Posted August 4, 2018 Share Posted August 4, 2018 @kurgut I had problems with them and FAR back in 1.3.1. Asymmetrical lift, low lift for area (compared with stock wings), and high drag. I still used them a whole lot because you can make some nice looking machines but not necessarily nice flying. It seemed like FAR helped but wasn't a solve. Are you using FAR in 1.4.5? I want it, but when I attempt to recompile the source for 1.4.5(which is another thing I did in KSP today) I get 3 errors but it completes. But then, I get no control surface operation and no lift/drag graphs and it makes me sad. Quote Link to comment Share on other sites More sharing options...

Oh ye, no I'm using it with realsolarsystem and realism overhaul (that includes patches for aerodynamics, or RSS don't remember) and work just fine, but ye you're right, in stock produce drag, and less lift, but stilll flyable for me.

EpicSpaceTroll139 Posted August 4, 2018 Share Posted August 4, 2018 (edited) Yet more work on the kOS script. Been sitting here listening to AWOLNATION Sail Instrumental as I go along. Decided to let my script log error and time to a couple text files, and was lucky enough to catch one of the boosters with a navigation error on the first go. For those interested in mathy/codey/controlley stuff, look here: Spoiler So, there is something wrong going on with the Starboard booster. It is wiggling all over the place and looks like an audio waveform lol. Anyways, so basically what these graphs are showing the angular error of the trajectory in the North/South and East/West Directions. Basically the script generates a vector (Called "Desired Descent Vec" or DDV for short) pointing from where the ship is to a point above the landing pad at some altitude k*(ship:altitude). It tries to align the direction of travel with this vector. The script generates the North/South and East/West angular error values from the differences in direction between the DDV and the surface velocity vector. It feeds each error term into a PID loop Basically, a PID loop is a type of control loop used in real life to control systems, which does not need a lot of knowledge about the system for it to work. It can't control everything but it's simple and so is used when possible. PID stands for Proportional, Integral, and Derivative, which defines the 3 terms that are used. The first value used is the proportional term, which applies an initial correction. The booster says "Hey my trajectory is 20 degrees north of where I want it. I'll tilt the booster some angle kP*20 to try to correct it." The next value used is the integral term, which accounts for a steady error over time. The booster says "My trajectory has been an average of 5 degrees north of where I want it to be for most of this time. I'll tilt the booster additionally by some angle kI*5 to account for that. The last value used is the derivative term, which helps to dampen the corrections to prevent overshoot. The booster says "Hey my trajectory has swung 10 degrees over the past second, if I don't slow down I might overshoot. I'll further add some angle kD*10 to dampen out the steering." So it ends up with an output looking like Output = kP*Error + kI*Integral(Error) + kD*Derivative(Error). You can read more about PID control here and here if you want. Now looking at the graphs, it appears that the Starboard booster is maybe overshooting? It's kinda wigging out at the very least haha. So I figured perhaps I should increase the derivative gain kD to fix it. No that made it worse! Decreased it and now they seem to be on target. Not really sure how that works, but ok! It would be so much easier to tune the gains if the booster moved at constant velocity through and atmosphere of constant density, but it's not so I think standard PID loop tuning methods don't really apply. So with my new information I started fiddling with stuff. At first I fiddled with it the wrong way, so this happened: Neither of them close to being on the pads. lol So I just did the opposite of what I had thought would fix it. And now they're both on the pads again. The question now is: Will it keep working, or is this guy still hanging out with me? Edit: @Triop Oh man so I'm not the only getting that godawful graphics bug Edit2: @Kronus_Aerospace I've tried uninstalling scatterer and the bug persists.

In which case Scatterer may be at fault. It's extremely annoying for me as well. Fortunately enough changing vessels at least delays the onset of the scattering. Didn't stop me from enjoying my new F-86 Sabre, though. I don't know what it is with these early jets, but they're such a pleasure to build and fly. 129 parts, came together in an afternoon, and handles darn near identically to the real thing (Mach .9 top speed, good but not absurd maneuverability, lands like a dream with flaps).

MisterKerman Posted August 4, 2018 Share Posted August 4, 2018 (edited) Quite proud of the way this turned out. I've made a proper commercial variant of my WorkHorse Lander. I call it: Pony. It has all the science gear except a command module. If that comes up I'll send a proper WorkHorse, but it seems unworthy of concern right now given the progress I've made broadening my space agency's services to include multiple leg moon journeys while still generating efficient profit margins toward furthering our program's reach. Should be a more-than-adequate solution to my multiple leg journey contracts. I'll dock a habitat to act as a passenger terminal at my refuel station in LKO, shuttling passengers to the terminal in an SSTO from KSC. Once they arrive I'll send the passengers in 2 separate journeys depending where their destinations are, then drop them back off at Kerbin safe and sound. I can smell the money.

purpleivan Posted August 4, 2018 Share Posted August 4, 2018 Took a crew of 16 (4 to the surface) of Dres for the Terminus (weekly) challenge. This involved sending a lander and a rover to the surface and putting four satellites into orbit of the little spud. Quote Link to comment Share on other sites More sharing options...
kurgut Posted August 4, 2018 Share Posted August 4, 2018 (edited) Now simulating the Pathfinder mars rover landing, , for the next mars window. After a direct reentry, drogue deployed first then fairings and heatshield jetisoned, and at about 200m above terrain, retrorockets firing to geeently land the rover, and just at touch down, this "delivery" system is decoupled, and crashed on Martian surface Slowing down Good bye heatshield, now FIRE! Landed, good bye delivery system! Ready to explore now Edited August 4, 2018 by kurgut Quote Link to comment Share on other sites More sharing options...

I like the precision! Out of curiosity, does it aim for a specific geographic coordinate next to the flag that it lands on, or does it target the flag itself and land close to it? Either way it's cool. On a different note, explosions can only mean good things: Actually the script landed the booster just fine, just one of the static solar panels forming part of a decorative X on the pad couldn't take the heat of the rocket exhaust. Really seems kind of silly that a solar panel makes such a spectacular explosion when melting. Anyways, I might have the guidance logic behaving now. Spoiler Slightly concerned by the magnitude of overshoot on the port booster, but as long as it works I guess it's fine. Don't tell Malcolm though.

Triop Posted August 4, 2018 Share Posted August 4, 2018 Today we got 2 survey contracts in one mission. First we flew our science jet to the Dessert Airfield where a tanker refueled it. After the first temperature measure we went for the pressure readings. After that we did the remaining two temperature readings and landed at Woomerang launch site. We are now waiting for a tanker because we are out of fuel... Quote Link to comment Share on other sites More sharing options...
