HIDDEN DRAG LINK FOR THRUST REVERSER ASSEMBLY
20230012009 · 2023-01-12 · ·

A thrust reverser assembly may comprise a cascade of vanes and a sleeve configured to translate relative to the cascade of vanes. The sleeve may include an inner sleeve portion, an outer sleeve portion, and a pressure sleeve portion. The pressure sleeve portion may be located radially inward of the outer sleeve portion and may extend forward from the inner sleeve portion. A blocker door may be hingedly coupled to the pressure sleeve portion. A drag link may be pivotably coupled to the blocker door. A forward end of the drag link may be configured to deploy radially inward in response to aft translation of the sleeve.

Turbofan engine comprising a set of rotatable blades for blocking off the bypass flow duct

A turbofan engine having a duct for a bypass flow and blades. Each blade is mobile between a stowed position and a deployed position. Each blade includes a rigid core a second, free end, and a sheath into which the core and the second end slide. Each sheath includes a first part which surrounds at least one part of the core and the second end, and an aileron which extends beyond the core facing the first part of the adjacent blade. The sheath is made of a flexible material such that the bypass flow causes the sheath to come into contact with the first part of the adjacent blade. A turbofan engine of this kind makes it possible to create blades whose production costs are low but whose aerodynamic behavior is effective.
