MDO Workflow

Results

Take away

  • The present work defined the optimal level of systems electrification considering the impact on aircraft Life Cycle Cost and on the certification margins for minimum performance, systems safety and external noise constraints.
  • Four on-board system architectures with different level of electrification are identified for a small regional aircraft. Each one is inspired by the present aeronautical trends.
  • The integration of Safety/Minimum Performance analyses on the MDO workflow will reduce the need of modifications during the certification phase reducing the aircraft development time and cost.
