System Geometrical management

摘要

This process, based on end to end philosophy defines the way of managing geometrical specifications concerning the aircraft during its complete lifecycle. Final geometry of an aircraft is the result of many manufacturing operations performed by many stakeholders. As a result, geometrical management is centered on Frontier and Interface management, following the sharing of responsibilities of vehicle systems and integrators. System geometrical Management is based on functional analysis of the Helicopter vehicle. This is a top-down approach leading to systems specification at each level of the Aircraft assembly, and following the 3 main phases of the Helicopter lifecycle: Design development, Industrialization (MAP) and Serial life. This approach leads to a cascade of specification in line with the product cascade, where Frontier specification becomes an input data for system design and manufacturing. This process guaranties the transversal robustness of design and industrial process against A/C performance criteria.
