Sieht nicht so schlecht aus👍🏻 Ich glaube aber, dass deine Turbine viel zu groß ist für die Brennkammer. Ziel ist es, in der BK eine isobare Verbrennung bei ca. 3-4 bar einzustellen (Radialverdichter wäre hierfür angebrachter, da du diesen Druckgradient damit leicht zusammenbekommst bei kompakterem Bauraum). Probiere mal den Druck nach dem VD und in der BK zu messen, das würde dir einen guten Überblick verschaffen. Wenn du dir zB eine Allison-Turbine ansiehst, wirst du feststellen, dass der Ansaugdurchmesser für die abgegebene Leistung in Verhältnis viel kleiner ist als bei deiner Turbine. Auf jeden Fall weiermachen, nur so lernt man dazu
@Praendy

Hi, die Turbine läuft prima. Mein Verdichterdruck liegt max bei 2,2 Bar. Ich benutze einen Radialverdichter von Garrett, bin aber jetzt bei einem Mitsubishi TD 13 Rad.

The plane comes from the fact that you're in a hot start moment if you will. We'll use the term hunt start when a turbine has not spoiled completely but is firing in sustaining thrust and combustion. It will not continue to spool and can cause significant damage to your turbine. You never really achieved spool up unfortunately. You're not letting it spool High Enough or you do not have enough fuel flowing into the combustion chamber.
