Solution for trailing edge reinforcement and tip opening

The RTZ Solution™ is developed to eliminate aft shear web disbonding around the web's fishmouth geometry. Peeling stresses in the adhesive joint occurring due to out-of-plane deformation (or breathing) cause the disbonding of the aft shear web. The same breathing phenomena is also often the root cause of transverse cracks on the unsupported transition zone panels. 

The RTZ Solution™ will positively affect the operation of your wind turbine as a panel reinforcement in the transition zone:

• The RTZ Solution™ eliminates failures in the aft shear web foot connection.
• Helps large blades with aft shear web to avoid excess out-of-plane deformation of the unsupported panels in the root transition zone and thereby mitigating the risk of cracks on them.
• Significantly increases the anticipated lifetime of your blades.
• The installation of the RTZ Solution™ does not affect the integrity of your blade.

How it works

The RTZ Solution™ significantly reduces the peeling stresses in the transition zone area where the aft shear web starts and eliminates defects occurring in the region.

The solution connects the two unsupported shells and reduces out-of-plane deformation.

A strong focus of the design is to make it easy to install up-tower in a safe way without altering the aerodynamic profile of the blade.
