A320/A319 Sharklet Retrofit Checkstress and SRM

Sitec was contracted to deliver Check stress justification on the Single Aisle A320/A319 Sharklet Retrofit for static and fatigue justification. 


This new wing included the retrofit of a large wingtip device aimed at enhancing the payload-range performance of selected A320 and A319 family models.  The analysis work included a comprehensive  assembly of wing components including the leading and trailing edge, wing covers, spars, ribs and more importantly the new joints for the addition of the performance enhancing Sharklet device.  The work performed required a strong familiarity and knowledge of methods and processes for detailed wingbox sizing to support the generation of certification documents for both the baseline configuration and sensitivity to repair to support the certification exercise and repair manual for this model derivative.
