Beschreibung
Zusammenfassung:	The invention discloses a sealing element and a sealing method of a complex curved surface structure cavity. The sealing element of the complex curved surface structure cavity comprises a core block and an air bag, the shape of the core block is adaptive to the complex curved surface structure cavity, the core block is a whole block unit body, or the core block is formed by combining a plurality of block unit bodies, the air bag covers the outer side of the block unit body, the air bag is made of a flexible material, and the air bag is provided with an air valve for inflating or deflating. Thesealing element can adapt to various irregular, rough and complex curved surface sealing, the harder core block can resist the deformation of the sealing element caused by internal and external pressure difference, the air bag made of the flexible material can be attached to the surface of the complex curved surface structure cavity to form a continuous sealing curved surface, and the sealing performance is good.
