Aeroseal and method of forming the same

A seal assembly comprising:

• a first member;
• a second member spaced apart from the first member;
• and
• an aeroseal positioned between the first and second members, the aeroseal comprising:
• a first C-shaped portion including first and second distal ends, defining a first partially enclosed volume within the first C-shaped portion;
• and
• a second C-shaped portion including third and fourth distal ends, defining a second partially enclosed volume within the second C-shaped portion, wherein the second C-shaped portion is disposed in the first partially enclosed volume of the first C-shaped portion, wherein the second C-shaped portion includes at least one interior bead, protruding toward the second partially enclosed volume.

A method for forming an aeroseal for an aircraft wing, the method comprising:

• positioning a smaller C-shaped portion in a partially enclosed volume of a larger C-shaped portion;
• attaching a distal end of the smaller C-shaped portion to a distal end of the larger C-shaped portion;
• and
• attaching an opposite distal end of the smaller C-shaped portion to an opposite distal end of the larger C-shaped portion, wherein the smaller C-shaped portion defines a partially enclosed volume and wherein the smaller C-shaped portion comprises at least one interior bead, protruding toward the partially enclosed volume.
