Course # 603 –
Aircraft Structures and Repair Analysis III – Advanced
When a student completes this course she/he should be able to:
-
- understand fatigue concepts and fundamentals
- check the repair for inter-rivet buckling
- be familiar with the steps to solve advanced buckling problems
- possess an excellent knowledge of cold expansion of holes and how they improve fatigue crack growth life
- estimate joint load distributions
- grasp the fundamentals of the damage tolerance philosophy and damage tolerant repairs
- appreciate which fastener holes are fatigue-critical
- know how to construct residual strength diagram
- understand stiffened structures, the effects of fastener pitch, stiffener spacing and other variables on residual strength of a stiffened panel
- explain the idea behind “zero-timing” of fastener holes and the pitfalls
- how/when to communicate with OEM for repairs beyond SRM (Structural Repair Manual) limits
- have a solid familiarity with NDI techniques used, their applications and limitations
Prerequisite:
- preferably taken FATIGUE CONCEPTS 602 or Boeing/Airbus Intermediate Structural Repair training and,
