Root Cause Analysis is the novel art of finding the underlying reason To why blades are failing.
The present standards do not account for the “real loading”, i.e. combined loading, which translates into more blades failing in the field.
Blade failures seen in the field:
Based on your inspection reports we are able to pinpoint the root cause of the structural failures in your blades. We have expert knowledge of blade failures in general with a competitive advantage in structural blade failures.
Whether your failure stems from a structural failure such as composite fatigue or is a design error we will in most cases be able to recommend a preferred action to repair your blades.
Consulting Bladena is part of lowering your risk of future blade failure.
Blades in operation are subjected a combined loading, i.e. the “real” total loading comprised of the edgewise loading (gravity) and aerodynamic forces (wind) leading to a compli-cated 3-dimensional loading scenario that will force the blades to deflect leading to blade failures.
Failure modes leading to blade failures
From your inspection reports Bladena is in many cases able to pinpoint the present failure mode of your blades and suggest the preferred way to correct the failure.
Blade failures seen in the field:
- Erosion
- Structural blade failures
- Lightning strikes

Failure modes leading to blade failures
- Breathing
- Buckling
- 3D waves
- Peeling in adhesive bonclines
- Twisting Cross Sectional Shear Distortion
