Abstract:Excellent aircraft structural design is a requirement for the commercial success of civil aircraft, and it needs to be achieved through structural design for producibility. Design for producibility can significantly reduce the cost, improve quality and reliability of civil aircraft structure, and shorten the development cycle. The earlier design for producibility is initiated, the greater the benefits. Considering producibility at the initial design stage can reduce the time and cost of extensive modifications during the manufacturing phase. The design of aircraft structures meets functional and strength performance design requirements while considering several other key factors of producibility: simplicity of design, choice of materials, appropriate tolerances, flexible manufacturing alternatives, and clarity and conciseness of technical data. The optimal combination of materials and processes in a part’s design for producibility can be obtained through a procedural approach to a trade-off analysis of the three aspects of the design goals. This paper also provides a producibility checklist, which can be used to evaluate the producibility of part and assembly designs.
