Triebwerksberechnung fehlerhaft
(german)
Hallo Keen.
ich habe letztens mich mit den Atmosphären Triebwerken auseinander gesetzt und hab da einiges interessante dinge herausgefunden.
bis jetzt geht es nur um die Triebwerke für kleine Blöcke!
alle test wurden auf realistischen Einstellungen gemacht!
ein kleines Triebwerk kann eine kraft von 96000 nowten ( 96 kilonowten) aufbringen was eine masse von etwa 9000 kg bewegen könnte.
ein großes kann dabei etwa 570000 nowten ( 570 kilonowten) aufbringen was etwa 57000 kg entspricht. nun hatte ich ein schiff aus dem workshop ( ohne mods) geladen was ein gewicht von 350000kg hatte wen es leer war. und ein gewicht von über 470000kg wen es komplett gefüllt war.
das schiff hatte nach unten 4 große Triebwerke und 12 kleine was nach meine Rechnung reichen würde um ein gewicht von etwa 350000 kg zu bewegen. jedoch flog das schiff auch voll beladen.
nach weiteren testen kam zusätzlich heraus das 1 großes triebwerk die kraft von 6 kleinen hat. und das die angezeigten werte nicht zu 100% stimmen. so konnte eine rakete mit 1 kleinen triebwerk nicht starten wobei die gesamt masse 9500kg war. erst wen ich unter 9400kg fällt konnte das Triebwerk die rakete bewegen. der wert schwankt leicht.
meine Vermutung:
da weitere Test zeigten das die meine Rechnung stimmt und das die Triebwerke die entsprechende kraft aufbringen können scheint dies ein Fehler zu sein der passiert wen ein schiff in ein spiel rein kopiert wird was aus einer älteren Version stammt. jedoch ist das schiff wohl von 2020 wo es meines Wissens nach keine Änderungen an der Triebwerken gab.
hier ist ein link zu dem besagten schiff was ich aus dem Workshop habe https://steamcommunity.com/sharedfiles/filedetails/?id=2105358947
und so nebenbei als Anmerkung. einige blocke sind vom Gewicht her einfach zu schwer. man nehme als Beispiel den kleinen lichte Panzerung block der angeblich 20 kg wiegt. wobei ich aus Erfahrung sagen kann das eine Kiste die 50x50x50cm groß nicht so schwer ist. und da der block nach 2 Treffern aus einem gewähr Kaput geht muss der in drin hohl sein. das aber nur nebenbei als Anmerkung. letztendlich muss da sowieso nur das Verhältnis stimmen!
I have the same bug
Hello, Nax,
thanks for letting us know about your concern and while I really am "wowed" about the level of information provided here, can I ask for more? How exactly did you find out, that small thruster can generate 96kN? On full single thruster override the read-out power is 86,2 kN; that is approximately 8 770 kg (taken from 1 kilonewton is equal to 101.9716005 kilograms).
Same for the big one - on full override the read-out is 517,6 kN corresponding approximately to 52719,3 kg.
Also... tried the ship you provided the BP for and upon checking it empty and fully loaded with stones, it came out that it actually weights only 114 928 upon pasting (clean, no mods, Earth base map) and ~271 130 when fully loaded (you can check in Info tab of the grid). So in this light, I can say that yours as well as mine calculations are correct and there is no reason why this ship should not move when fully loaded.
All these tests were also done on new, unmodded world (Earth Base) with ALL settings in Advanced settings before starting the world set to Realistic.
I´m not saying my calculations are correct, just looking all around on the internet and trying to convert it - physics never was my strong side :) So please if you do know more, have and can provide the formulas you used for calculation, that would help a great deal!
Although my calculations also show that the big thruster is roughly 6x the power of the small one :)
Also if you can provide some world / safe file where you done these test alongside with the formulas and enlightening me more into this issue, all of this would be great help!
You can access your save files by typing% appdata% into your Windows search bar and you will be redirected to the hidden roaming folder. After that just follow: \ Roaming \ SpaceEngineers \ Saves. There should be a folder with your SteamID and your saves.
Please zip the file and attach it here. If you are having difficulty attaching files you can optionally use Google Drive. When sharing a google drive link please make sure it is set to be downloadable by anyone with the link.
Thanks in advance for all the info.
