    摘要: Offenbart wird ein Schaufelgittersegment (110, 120, 130, 140, 150) eines Schaufelgitters für eine Strömungsmaschine, das eine Plattform (10) mit einer Plattformoberfläche sowie mindestens zwei Schaufelblätter (20, 30) umfasst. Die Plattformoberfläche weist eine an das erste Schaufelblatt heranreichende Vertiefung (111, 121, 131, 141, 151) auf, welche die Druckseite (21) des ersten Schaufelblattes stromab von 80% der axialen Gitterbreite (g) stromab Anströmkanten (23, 33) berührt und die Druckseite (21) des ersten Schaufelblattes bis zu maximal 80% der axialen Gitterbreite (g) stromab Anströmkanten (23, 33) berührt. Mindestens ein tiefster Punkt (112, 122) der Vertiefung liegt wenigstens 90% der axialen Gitterbreite (g) stromab der Anströmkanten (23, 33).
    Offenbart sind ferner ein Schaufelgitter, ein Schaufelkanal, eine Plattform, eine Strömungsmaschine und ein Flugzeugtriebwerk.

    摘要: A vane cooling system for a gas turbine engine comprises a vane (21) arranged on a stator and having a chamber (23) extending continuously from a radially inner end to a radially outer end of the vane. The vane (21) has; a radially inner inlet (24) and a radially outer inlet (25), a first cooling fluid feed (39) in communication with the radially inner inlet (24) and a second cooling fluid feed (28) in communication with the radially outer inlet (25), The first cooling fluid feed (39) has a higher pressure than the second cooling feed (28). A flow adjustment device (30) is arranged for adjusting a flow of the second cooling fluid feed into the radially outer inlet (25).

    摘要: A strut-flap vane system for a turbomachine includes a vane strut (211) comprising an airfoil portion (211 b) and a strut mount (211a) extending in a radially outward direction from the airfoil portion. The strut mount forms a hollow semi-cylinder and includes threading (211 c) on an outer diameter thereof. The system includes an aft mount portion or portions (201) defining a hollow semi-cylinder configured to form a strut cylinder (203) with the strut mount such that the aft mount portion can be disposed in contact with the strut mount to form the strut cylinder. The strut cylinder defines a cylinder opening (205) and the aft mount portion includes threading (201 c) on an outer diameter thereof that aligns with the threading of the strut mount to allow a strut spanner nut (207) to mesh with both the strut mount and the mount portion. Furthermore, a method of assembling is disclosed.
