TRANSCRIPT
Airbus A330 Weight Variant 08x Wing Box CertificationBackgroundAtkins has worked with Airbus since 2008 on the Long Range (A330) Aircraft. Work to date has included:
• Static and D&DT certification of A330-200F wing box (Freighter)
• Static and Fatigue certifications of all passenger weight variants since 2008
• Structural Repair Manuals
The A330 Weight Variant 08x (WV08x) is a new weight variant (max take off weight 242t) addition to the Long Range fleet. Atkins was selected to assess the impact of the higher operating loads, and redesign the wing box structure as required.
Atkins’ involvementOur role was ownership of design and certification on behalf of Airbus Americas Engineering (AAE) for:
• Wing Box Ribs
• Pylon Support
• Fixed Trailing Edge
• Wingtip / Winglet
• Main Landing Gear Structure Support
Within this, specific activities have included: initial concept studies, preliminary design analyses, design for manufacture and certification analyses, and static and D&DT analysis for metallic and composite wing box structures.
As a global business we can be flexible and responsive to our customers’ needs. In this case, the project was delivered through Atkins in Seattle with work packages split between our offices in the UK and US. Atkins has been responsible for the majority of work to support the preliminary design review (PDR) and critical design review (CDR) of the wing box, and produced Design Dossiers to reflect the ultimate design of the WV08x wing. The small team supporting initial concept studies has now grown to around 30 engineers involved in detailed certification analyses.
Atkins has been providing high quality engineering services to AAE for many years. We invested in providing an on-site team to ensure that we are fully integrated within the customer team, and by employing direct hires we ensure that our customers receive high levels of continuity and service. This approach has also enabled Atkins to retain product knowledge of the A330 wing within the business, and historically we have been able use this knowledge to increase efficiencies in the design and certification process, ultimately reducing total project costs.
