Abstract:With the rapid development of domestic commercial aircraft development and manufacturing technology, and in the context of exploring the implementation of phased control, the domestic commercial aircraft development procedures need to be further refined and unified. The comprehensive development of manufacturing technology, information technology and management has changed the original model of commercial aircraft development. This paper summarizes the principle of commercial aircraft development, analyzes the development stage division principle of international mainstream commercial aircraft manufacturers and the application of advanced methods in commercial aircraft development, and defines the commercial aircraft development phases control for the first time. Combined with the existing program development experience and the actual demand, this paper preliminarily puts forward the development process mode and model of commercial aircraft based on access control and control implementation of concurrent engineering, and makes a preliminary study on the implementation timing of development activities such as demand confirmation, scheme design, manufacturing, integration verification and operation support, and analyzes the logical relationship between access control review and development process, so as to provide reference for the elaboration of commercial aircraft development procedure and practical work arrangement.
