Abstract

Ein Initiator (1), der bei Erreichen einer Schwelltemperatur ausgelöst wird, um die Wirkung der Entzündung eines Festtreibstoffes (12) eines Feststoffraketenmotors über der Schwelltemperatur herabzusetzen, weist eine Druckkammer (3) oder dergleichen Druckeinrichtung auf, deren Druck bei Erreichen der Schwelltemperatur in Bewegungsenergie zur Auslösung des Initiators (1) umgewandelt wird.

Figure imgaf001
An initiator (1), which is triggered upon reaching a threshold temperature to reduce the effect of igniting a solid fuel (12) of a solid rocket engine above the threshold temperature, has a pressure chamber (3) or the like pressure device whose pressure upon reaching the threshold temperature in kinetic energy is converted to trigger the initiator (1).
