Description
Claims (9)
dadurch gekennzeichnet,
daß diese Kanäle (112) zentrale Längsachsen aufweisen, welche in einer radialen Querschnittsebene auf konzentrischen Kreisen (116 und 118) liegen, deren Mittelpunkte auf der Längsachse des zylindrischen Treibstoffkörpers (64 bzw. 66) liegen;
daß projiziert auf eine radiale Querschnittsfläche des Treibstoffkörpers (64), die Achsen der Kanäle (112) auf dem ersten konzentrischen Kreis (116) auf anderen Radien liegen als die Achsen der Kanäle (112) des zweiten konzentrischen Kreises (118) und die Radien durch die Achsen radial benachbarter Kanäle (112) um einen bestimmten Winkel gegeneinander versetzt sind;
daß der Umfangsabstand zwischen den Achsen benachbarter erster Kanäle (112), die auf dem ersten konzentrischen Kreis (116) liegen, gleich dem Umfangsabstand zwischen den Achsen benachbarter zweiter Kanäle (112) ist, die auf dem zweiten konzentrischen Kreis (118) liegen; und
daß die Durchmesser des ersten und des zweiten konzentrischen Kreises (116 und 118) sich zueinander verhalten wie 2,91 zu 1,93.
wobei jeder der Treibstoffkörper (64 bzw. 66) mit parallelen, durch sie hindurchführenden Kanälen (112 bzw. 134) versehen ist, welche in den Stirnflächen an Stellen münden, die in Radialrichtung einwärts von den Außenseiten jedes Körpers liegen, wobei
diese Kanäle (112 bzw. 134) in jedem der Treibstoffkörper (64 bzw. 66) durch Oberflächen begrenzt sind, an denen eine Verbrennung stattfindet, um Gas zu erzeugen, welches die Kanäle durchströmt; und
die stückigen Körper (64 bzw. 66) von einer Struktur (70) umgeben sind,
dadurch gekennzeichnet, daß
jeder Treibstoffkörper (64 bzw. 66) an seiner Oberfläche mehrere Ausnehmungen (178 bzw. 180) aufweist, welche sich entlang der Außenseite des Körpers zwischen den Stirnflächen (108 und 110) erstrecken; und daß
eine gestreckte und elastisch nachgiebige Halteeinrichtung (170, 172, 174) sich entlang der Ausnehmungen (178 bzw. 180) und in diesen erstreckt und aus diesen herausragt und an einer die Treibstoffkörper (64 bzw. 66) einschließenden Hülse (70) zur Anlage kommen und die Körper (64 bzw. 66) in einer solche Position halten, daß die durch sie hindurchführenden Kanäle (112 bzw. 134) in Axialrichtung miteinander fluchten.
