Research on Civil Aero Engine Requirements Development and Management

Abstract

Aero engine not only need to meet aircraft requirements and also airworthiness and other stakeholder’s requirements. Due to the increasing complexity of requirements, the development of civil aero engine within the required time and cost present a considerable challenge. In this work, a requirements development and management approach is introduced in civil aero engine development process, the aim is to bring forward new experiences on aero engine requirements management in practice. The requirements and design definition is presented in a requirement V model and the aero engine design is decomposed from the whole system to sub-systems and then to the components, a typical civil aero engine requirements architecture is defined. Based on the requirement development model, the requirements related files of aero engine are illustrated. The requirements flow down case shows how requirements allocate and interacting between systems. By managing the status of requirements throughout the whole engine development, the traceability between requirements and design and verification data are established to ensure the consistency of requirements.
