Description

Radialturbine. Bei den bekannten Radialturbinen sind die Geschwindigkeiten für die Ein- und Austrittskante der Laufschaufeln den Geschwindigkeitsänderungen des Treibmittels im Laufrade nicht richtig angepaßt, wodurch eine Erhöhung des Austrittsverlustes entsteht.Radial turbine. In the known radial turbines, the speeds are the changes in speed for the leading and trailing edge of the blades of the propellant in the impeller is not properly adjusted, which increases the leakage loss arises.

Beim Erfindungsgegenstand wird dieser erhöhte Verlust dadurch vermieden, daß der annähernd tangential eintretende Treibmittelstrahl durch die Laufschaufeln so umgelenkt wird, daß bei Freistrahlturbinen Eintritts- und Austrittskante gleiche Geschwindigkeit besitzen, bei Überdruckturbinen die Austrittskante größere Geschwindigkeit als die Eintrittskante, bei Unterdruckturbinen die Eintrittskante größere Geschwindigkeit als die Austrittskante besitzt.In the subject matter of the invention, this increased loss is avoided by that the approximately tangential entering jet of propellant through the blades is deflected in such a way that the leading and trailing edges of free-jet turbines are the same Have speed, with overpressure turbines the trailing edge is faster than the leading edge, with vacuum turbines the leading edge has greater speed than the trailing edge.
