Solid rocket engine combustion chamber shell light connector

The invention relates to a solid rocket engine combustion chamber shell light connector, which comprises an inner surface and an outer surface, and is characterized in that a space radial cross section enveloped by the inner surface and the outer surface of the connector is of a hollow-out structure. The hollow-out structure can be provided with a lightening slot; the hollow-out structure can be also in a frame style, a stiffening ring and a ribbed plate are arranged inside as a support structure, and the inner surface and the outer surface of the connector are covered by skins; and the hollow-out structure can be also in a dot-matrix type, a dot-matrix structure is adopted inside for supporting, and the inner surface and the outer surface of the connector are covered by skins. Compared with the prior art, according to the solid rocket engine combustion chamber shell light connector provided by the invention, the connector quality is reduced, and the passive quality of a solid rocket engine is greatly reduced without influencing a bearing strength performance of the connector.
