DIVERGENT SEAL ARRANGEMENT FOR A CONVERGENT/DIVERGENT NOZZLE

摘要

The divergent seal of a thrust vectoring nozzle has an elongated corrugated stiffening sheet (46) with a backbone (52) secured to the air side. The backbone (52) is stiff perpendicular to the sheet (46), but flexible in torsion. A face sheet (56) secured only at the upstream end covers the gas side of the stiffening sheet (46).
