Optimized Aerostructure and Systems Installation

AKKA offers a comprehensive set of capabilities in the design and validation of primary and secondary aerostructure (metallic and composite) as well as in systems installation (Electrical System / Mechanical System and Flight Test Installation).

For more than 25 years, AKKA has supported major aircraft manufacturers and aerostructure suppliers to develop and certify optimized components and systems installation operating from feasibility phase to certification.

Primary and Secondary Structure

  • Preliminary study and design principle
  • Conceptual design & architecture studies
  • Kinematic definition and analysis
  • Elementary part Design 3D / drawing file 2D and assembly drawing, full 3D
  • Manufacturing support at FAL, concession, non-conformity
  • DMU management, clash and troubles analysis, reports
  • Weight management
  • Reference composite manual definition

AKKA Mechanical engineering teams have developed a key expertise in composite including the following skills:

  • Monolithic and sandwich composite material
  • Resin Transfer Molding (RTM)
  • Liquid Resin Infusion (LRi)
  • Loaded and unloaded composite part
  • Electrical bonding application (MBN)
  • Fasteners available for composite assembly
  • Ply drop off / ply table definition
  • Repairs
  • Materials association

Component Integration and 3D Tolerancing

AKKA’s capability in tolerancing brings solutions that ensure the correct mounting of various assemblies. Our capability  offers opportunities to reduce cost and improve quality covering many functions including aerodynamics, stress, weights and Interchangeability:

  • Analysis and solutions for assemblies in terms of Geometric Dimensioning and Tolerancing:
  • 3D Calculations to check installation feasibility and compliance with installation, interchangeability and industrial design requirements
  • Proposal of alternatives and solutions: change of design principal, proposal of tooling, change of manufacturing or installation process
  • Frontier Drawings and technical reports.

Stress & Thermics Analyses

From concept pre-studies to type certification and serial life modification; design and installation studies are supported by advanced capabilities in stress and thermics analyses.

  • Stress validation studies (analytical or numerical approach)
  • Global FEM creation / modification
  • Detailed FEM creation / integration / modification
  • Static stress analyses
  • Fatigue and damage tolerance analyses
  • Dynamic analysis
  • Analytical stress methods (“hand calculation”)
  • Stress test activities
  • Stress validation for First Flight or Type Certificate configuration and associated justification
  • Weight Saving campaign Management
  • Material Qualification
  • Structure Repair Manual

Electrical & Mechanical Systems Installation

  • Mechanical System Installation (MSI) – air conditioning, water, oxygen, fuel, hydraulic, Inerting, bleed (ATA 11 / 21 / 25 / 27 / 28 / 29 / 30 / 32 / 34 / 35 / 36 / 38 / 47)
  • Electrical System Installation (ESI)
  • Flight Test Installation ATA 89
