Geometrical Management Leading to Merge System Engineering APQP

摘要

Helicopter is a complex system regarding integration of systems. During development phase of a new H/C, design office deal with MMEL (Master Minimum List Equipment), Optional equipment package for specific missions (i.e. Oil & Gas, SAR...) and Manufacturing constraints for lead-time and cost optimization. The Geometrical Management presented today is derived from ARP4754A standard in Aeronautics. The Aerospace Recommended Practice (ARP) is a guideline for development of civil aircraft and systems. This process, based on end to end philosophy defines the way of managing geometrical specifications concerning the aircraft during its complete lifecycle. System geometrical Management starts with System Engineering by functional analysis of the Helicopter vehicle during Design development phase, then APQP focus on industrial maturity and repeatability during industrialization phase and finally control plan is deployed after Entry into service for serial life This is a top-down approach leading to systems specification at each level of the Aircraft assembly, as in Final assembly line for H/C assembly & tests, Systems level and elementary parts.
