The invention relates to a method for manufacturing and designing a composite material bulkhead structure of an airplane. The method comprises the following steps of: S10: determining design requirements of a composite material bulkhead; S20: determining the structure, the material and the process scheme of the composite material bulkhead of the airplane according to the design requirements; and S30: modeling and analyzing the composite material bulkhead. The method for manufacturing and designing the composite material bulkhead structure of the airplane can provide technical support of researching the composite material bulkhead structures of the under-research and in-service civil airplanes in China, reduces structure weight, improves airplane performances, reduces using and maintaining cost, and improves economic benefits.
Description
technical field [0001] The invention belongs to the technical field of aircraft structure design, and in particular relates to a method for manufacturing and designing an aircraft composite material bulkhead structure. Background technique [0002] As we all know, in aircraft design, composite materials are more and more widely used in aircraft structures due to their excellent properties such as high specific stiffness / specific strength, corrosion resistance, and fatigue resistance. Composite materials can effectively reduce the weight of the aircraft structure and increase the commercial load of the aircraft; or increase the amount of fuel and increase the range of the aircraft. On the other hand, the application of composite materials can reduce the number of aircraft structural inspections, increase inspection intervals, and reduce aircraft maintenance costs, thereby fundamentally improving the economic benefits of civil aircraft throughout their service life.
