Patent ID: 8156727

Claim:
An adjustable-section fan nozzle comprising: a ring of deformable panels arranged close to a trailing edge of the adjustable-section fan nozzle, wherein each deformable panel comprises a dual-strip structure comprising an inner strip of thermally-insulating material together with at least one outer strip of metal, said inner and outer strips presenting different coefficients of expansion and being assembled in full flat contact one against another so that a variation in temperature induces deformation of said dual-strip structure caused by the difference between said coefficients of expansion, wherein controlled heater means comprise electrical resistances distributed over the surfaces of the at least one outer strip of metal and in thermal contact therewith, and wherein the assembled inner and outer strips cause each deformable panel to curve in a direction tending to reduce a flow section at an outlet from the nozzle when said controlled heater means are actuated.
