Convergent-divergent nozzle orientable axisymmetric and ejection.

摘要

Ejecting nozzle axially symmetric turbojet, converging-diverging, having, downstream of an ejection duct (1) of axis X, a first ring of converging flaps (3) hinged at the downstream end of the ejection duct (1 ) and actuated by first control means (6, 7, 14), and, downstream of the first vane ring, a second ring of diverging flaps (15) whose upstream ends (16) are articulated at the ends of downstream (17) of the corresponding convergent flaps (3) and whose downstream ends (19) are connected by connecting rods (20) to a pivoting ring (21) cooperating with a spherical portion (30) integral with a structure fixed (13), said pivot ring (21) actuated by second control means (24) in order to allow a deviation of the jet of gas ejection, characterized in that the pivoting ring (21) it is mounted with bearings s on the outside wall of the spherical part (30) in order to ensure the centering of said ring around said spherical portion.
