AXISYMMETRIC CONTRACTION/DIFFUSION EXHAUST NOZZLE DIRECTED BY GUIDE RING

摘要

PROBLEM TO BE SOLVED: To provide an axisymmetric contraction/diffusion exhaust nozzle directed by a guide vector ring without the risk of operation stoppage. SOLUTION: A guide means includes three axial direction openings 44 provided on a leg 43 combined with a fixed structure 2 respectively and whose center surface is crossed along the axis of a turbojet engine. A sidewall 45 of the opening 44 acts so as to guide three spherical rollers 41, which are combined with a vector ring 20 and mutually fitted in the diametrical direction pin 40 at regular intervals.
