Our solutions

Whether you’re an OEM looking to strengthen new designs or an operator seeking to extend blade lifetime, all our solutions are backed by deep research and proven in the field.

D-String®

Simple yet powerful.

D-String® eliminates cracks in the trailing edge max chord area by addressing blade “breathing” – a key root cause of failure.

How it works

By connecting blade panels, D-String® stops out-of-plane movement that leads to peeling stresses in adhesive bondlines—reducing crack formation.

Benefits

  • ROI in less than 2 years.
  • Prevents trailing edge cracks caused by edgewise loading
  • Extends blade lifetime and improves operational reliability
  • Cuts maintenance time and cost

In use on: Vestas: V80, V82, V90, V100, GE: 34a, 37c, LM: 37.3, 45.3

In use on: Vestas V47, LM 42.2, Gamesa G58, G97

D-TE™

Dual-purpose reinforcement and repair.

D-TE™ strengthens the trailing edge and offers a fast, cost-effective solution for tip area repairs, especially after lightning strikes.

How it works

D-TE™ joins blade panels to reduce peeling and deformation, enhancing structural integrity and resisting damage.

Benefits as a reinforcement

  • Prevents cracks and trailing edge openings
  • Reduces buckling during extreme loading
  • Decreases maintenance needs

Benefits as a repair

  • Effective regardless of weather
  • Keeps damaged blades operational
  • Enables fast, low-cost, up-tower repairs

X-Stiffener™

Built to prevent leading edge cracks.
X-Stiffener™ counters twisting and peeling stresses, reducing the risk of longitudinal cracking on the leading edge.

How it works

Acts like a cross brace in a bookshelf, stabilising the blade to avoid shear web deformation caused by gravity and aerodynamic forces.

Benefits as a repair

  • Increases blade durability
  • Prevents early-stage cracks
  • Adds strength without adding weight

RTZ Solution™

Transition zone reinforcement made simple.
Designed to prevent disbonding and cracks in the aft shear web and transition zone of large blades.

How it works

RTZ Solution™ connects unsupported panels in the transition zone, significantly reducing peeling stresses that lead to failure.

Benefits

  • Quick, safe up-tower installation
  • Eliminates disbonding at the aft shear web foot
  • Prevents out-of-plane deformation and cracking
  • Maintains blade integrity

Licensing our technology

All our patented solutions are available for licensing.

OEMs can purchase patent and technology licenses to incorporate our innovations directly into blade design and production. Licensing allows full control over quality, supply chain, and implementation—enabling you to strengthen new designs and streamline manufacturing as you see fit.
