GUIDING MECHANISM FOR VARIABLE GEOMETRY VECTORING NOZZLES

摘要

Guiding mechanism for variable geometry vectoring nozzles, applicable to ga s turbines, capable of transmitting tangential forces acting on the external ring under vectoring loads onto the inner ring, avoiding the need of a joint between th e outer ring and the nozzle structure. With this purpose a guiding track (9) oriented circumferentially around the pivoting axis (8) is incorporated onto the oute r ring (3) and a track (10) oriented around a second axis (6) perpendicular to the previous is incorporated on the intermediate ring (2). The sledge element (11) joint to the intermediate ring (2), slides along the track (9) as a result of vectoring around the axis (8). For vectoring around axis (6) the sledge element (12), joint to the inn er ring (1) slides over the track (10).
