The invention discloses a cylinder body structure of a hollow multi-cavity
composite material launching cylinder and a forming method of the cylinder body structure, and belongs to the technical field of launching cylinder structures. The cylinder body structure of the hollow multi-cavity
composite material launching cylinder is made of composite materials and comprises an inner cylinder body, an outer cylinder body and longitudinal ribs, wherein the inner cylinder body is embedded in the outer cylinder body, the axial direction of the outer circumferential surface of the inner cylinder body is connected with the axial direction of the inner circumferential surface of the outer cylinder body through the longitudinal ribs, and a gas
flue is formed between the outer circumferential surface of the inner cylinder body and the inner circumferential surface of the outer cylinder body. The technical problems that a cylinder body of a
solid structure cannot be applied to heat emission, an emission cylinder is made of
metal materials, the weight is heavy, the
machining difficulty is large, the forming precision is low, assembling is complex, and the manufacturing cost is high in the prior art are solved; the cylinder body is made of the composite materials, the overall weight is reduced, the inner cylinder body and the outer cylinder body are connected through the longitudinal ribs, the gas
flue is formed,
machining and assembling are convenient, and the cylinder body structure of the hollow multi-cavity
composite material launching cylinder can be applied to heat emission.
