Claims (3)

Patentansprüche:Patent claims: 1. Leitschaufelung für axial beaufschlagte Dampf- und Gasturbinen mit Leitschaufeln von gleichbleibendem Querschnitt und gleichbleibendem Austrittswinkel, wodurch für den größten Teil der Laufschaufelung stoßfreier Eintritt des Treibmittels erzielt wird, dadurch gekennzeichnet, daß an den Leitschaufelkranz auf dem radial außenliegenden Teil der Schaufelung, aus welchem bei dem gewählten Querschnitt das Treibmittel nicht mehr stoßfrei in die Laufschaufelung eintritt, ein zweiter Leitschauf elkranz in starrer Verbindung dicht angeschlossen ist, der kleineren Austrittswinkel besitzt als der erste Leitschaufelkranz.1. Guide vanes for axially loaded steam and gas turbines with Guide vanes of constant cross-section and constant exit angle, which means that for most of the rotor blades, the entry of the Propellant is achieved, characterized in that on the guide vane ring on the radially outer part of the blade from which the selected one Cross-section the propellant no longer enters the rotor blades smoothly, a second Leitschauf elkranz is tightly connected in a rigid connection, which has a smaller exit angle than the first guide vane ring. 2. Leitschaufelung nach Anspruch 1, dadurch gekennzeichnet, daß die axiale Breite des zusätzlichen Leitschaufelkranzes nach außen zunimmt.2. Guide vane according to claim 1, characterized in that the axial Width of the additional guide vane ring increases outward. 3. Leitschaufelung nach Anspruch 2, dadurch gekennzeichnet, daß die Zunahme der axialen Breite stetig erfolgt.3. guide vane according to claim 2, characterized in that the increase the axial width takes place continuously.
