Sealing structure and sealing system for gas turbine engine

A sealing structure for a gas turbine engine, the sealing structure comprising:

• a plurality of cells connected to each other, wherein each cell extends along a longitudinal axis and comprises a cell plane orthogonal to the longitudinal axis, wherein each cell comprises a plurality of walls extending along the longitudinal axis, the plurality of walls defining a polygonal shape therebetween in the cell plane, wherein the polygonal shape comprises a plurality of edges and a plurality of vertices, the polygonal shape defining a cell area in the cell plane, wherein each wall defines a corresponding edge from the plurality of edges, and wherein each wall is connected to an adjacent wall from the plurality of walls at a corresponding vertex from the plurality of vertices;
• wherein each wall is shared by two adjacent cells from the plurality of cells, such that each wall defines corresponding edges of the two adjacent cells;
• and
• wherein each cell is connected to a set of adjacent cells from the plurality of cells at corresponding vertices from the plurality of vertices of the polygonal shape, such that each cell and the set of adjacent cells forms a plurality of connections at the corresponding vertices, wherein the plurality of connections forms a total overlap area between each cell and the set of adjacent cells, and wherein the total overlap area is less than or equal to 10% of the cell area.
