Next-generation wind energy engineering
RNGY develops advanced technological solutions to transform the wind energy sector.
Our innovations focus on durability, vibration control and sustainability, enabling a new generation of high-performance wind turbines.
EOLIA, a new generation of wind turbines
EOLIA is a breakthrough concept of wind turbine designed to address the future challenges of the energy transition.
Based on advanced aerospace technologies, EOLIA introduces a new architecture: lighter, more flexible, and highly damped structures designed to operate downwind.
This approach enables:
- A doubled lifespan of critical components
- A reduction of structural weight by up to 50%
- A significant decrease in carbon footprint
- A fully recyclable design
EOLIA represents a major step toward a more sustainable and competitive wind energy industry.
A growing technical challenge
Modern wind turbines are increasingly large and powerful, leading to complex dynamic behaviors.
Blades and towers are subjected to multiple sources of excitation:
- Aerodynamic loads
- Rotor-induced vibrations
- Offshore environmental conditions
- Wave-induced motion (floating wind)
These effects generate strong structural vibrations, leading to fatigue phenomena that reduce the lifespan of components and increase maintenance costs.
Traditional approaches based on stiffness optimization are no longer sufficient.
A new strategy is required.
Our Solutions
Dampblade
Reinventing wind turbine blades
RNGY is developing a new generation of wind turbine blades designed for offshore applications.
The Dampblade concept addresses two major industry challenges:
- Increasing lifespan by reducing vibration fatigue
- Ensuring full recyclability of blade structures
Unlike conventional composite blades, Dampblade uses a naval-grade aluminium alloy, enabling both durability and sustainability.
This innovation leverages over 30 years of expertise in vibration control from its parent company, ARTEC Aerospace.
Crisseol
Advanced acoustic damping solution
Noise generated by wind turbines, particularly nacelle rotation squeaks, is a growing concern for public acceptance.
These noises are caused by structural vibrations occurring during operation.
Crisseol integrates SPADD damping technology into the upper part of the tower, enabling:
- Efficient dissipation of vibratory energy
- Significant reduction of acoustic emissions
This solution contributes directly to improving the environmental integration of wind farms.
Flotteol
Controlling structural dynamics
Wind turbine towers are exposed to complex dynamic loads that generate low-frequency vibrations and long-term structural fatigue.
RNGY integrates advanced damping technologies directly into the structure, including SPADD and DAMPROD solutions. This approach enables:
- Significant reduction of vibration levels
- Increased structural lifespan
- Improved reliability and reduced maintenance
Unlike traditional methods, this solution controls vibrations through damping rather than increasing stiffness.
SPADD, Smart Passive Damping Technology
SPADD (Smart PAssive Damping Device) is a patented technology designed to dissipate vibratory energy efficiently.
It operates through a three-step principle:
- Deviation of structural deformation
- Amplification of mechanical response
- Conversion of energy into dissipation
These devices can be integrated directly into structures or applied externally, depending on the application.
SPADD technology has been successfully validated in demanding environments:
- Naval systems
- Aerospace structures
- Rail systems
- Scientific infrastructures
