Abstract

Eine Vormischvorrichtung (14) für ein Turbinen(30)-Triebwerk (2) umfasst: einen Hauptkörper (44) mit einem Einlassabschnitt (46), einem Auslassabschnitt (52) und einer Aussenwand (45), die zusammen mindestens ein Brennstoffabgabeplenum bilden; und eine Vielzahl von Brennstoffmischröhren, die durch mindestens einen Abschnitt des mindestens einen Brennstoffabgabeplenums verlaufen, wobei jede von der Vielzahl von Brennstoffmischröhren mindestens eine Brennstoffzuleitungsöffnung aufweist, die mit dem mindestens einen Brennstoffabgabeplenum in Fluidverbindung steht; und eine Schutzvorrichtung, bestehend aus mindestens einer Thermosicherung (211), die auf einer Aussenfläche mindestens einer Brennstoffmischröhre (60) angeordnet ist, wobei die mindestens eine Thermosicherung (211) ein Material einschliesst, das bei einer Entzündung des Brennstoffs im Inneren der mindestens einen Brennstoffmischröhre (60) schmilzt und eine Umlenkung des Brennstoffs von der Brennstoffzuführungsöffnung zur mindestens einen Bypass-Öffnung bewirkt. Auch ein Verfahren zur Herstellung einer Vormischvorrichtung (14) mit der Schutzvorrichtung wird bereitgestellt.
