[0002]
In order to facilitate the maintenance of the engine, the engine casing mostly adopts a horizontal open casing structure, which is formed by the butt joint of two half-ring casings. The inclusion design of the casing is the mainstream trend of engine design and an inevitable requirement for airworthiness. Due to the existence of horizontal splits, the inclusive design of the open case will greatly increase its mass, which does not meet the current requirements for aircraft structure weight reduction

The invention belongs to the technical field of horizontal split casing subsumption design, and particularly relates to a horizontal split casing subsumption structure. The structure comprises: two semi-ring casings, which are in butt joint with each other to form a whole ring casing; two semi-subsumption rings, which are manufactured from a composite material and are in butt joint with each otherto form a whole subsumption ring surrounding the whole ring casing; two semi-ring shells, which are in butt joint with each other to form an annular shell that covers the whole subsumption ring and is connected to the whole ring casing. According to the horizontal split casing subsumption structure, the whole subsumption ring formed by butt joint of the two semi-subsumption rings is arranged on the whole ring casing formed by butt joint of the two semi-ring casings, the subsumption requirement of the casing can be met through the arrangement of the whole subsumption ring, and the subsumptionring is manufactured from a composite material, has light weight and can meet the requirement for aircraft weight reduction at present.
Description
technical field [0001] The application belongs to the technical field of horizontally open case containment design, and in particular relates to a horizontally open case containment structure. Background technique [0002] In order to facilitate the maintenance of the engine, the engine casing mostly adopts a horizontal open casing structure, which is formed by the butt joint of two half-ring casings. The inclusion design of the casing is the mainstream trend of engine design and an inevitable requirement for airworthiness. Due to the existence of horizontal splits, the inclusive design of the open case will greatly increase its mass, which does not meet the current requirements for aircraft structure weight reduction. [0003] In view of the existence of above-mentioned technical defect, propose this application. [0004] It should be noted that the disclosure of the above background technical content is only used to assist in understanding the inventive concepts and techn...
