Rapid, multilocational and cost-effective aerodynamic, vibrational and acoustic data capture on turbine blades

Optimising monitoring & diagnostics of wind turbine blades

Civil structure designers and operators often struggle with capturing precise aerodynamic, vibrational, and acoustic data across their assets. Traditional methods either lack accuracy or are costly and intrusive.

Enter our solution: the first to simultaneously measure these parameters at multiple locations, rapidly and accurately. It's autonomous, simple, quick, and non-intrusive, offering a cost-effective way to optimize large-scale civil engineering structures. Experience the future of precision engineering today.

Revolutionise your wind turbine inspections with Aerosense

Cut down on high costs and limited data from traditional inspection methods. With Aerosense, there's no more reliance on drone-based inspections (~500 CHF per flight per turbine) or rope access inspections (~3000 CHF per turbine per day). Forget about the limitations of embedded fiber optic strain sensors that only measure strain and are too expensive.

Aerosense offers the potential to replace nacelle-mounted Lidar systems for wind inflow characterization on the rotor plane. Our unique selling point? Aerosense enables users to access a wide range of aerodynamic and structural monitoring and diagnostic use cases for wind turbine blades. All from a single low-energy, wireless, non-intrusive multi-sensor node. Choose Aerosense. Choose efficiency.

What it can do


The entire digital twin chain is operational

Deliver and display measurement data from the wind turbine on the dashboard


Improve aero-acoustic models, tools and designs

Assess sound pressure levels and infer the angle of attack from measurement data


Detect and classify surface damage such as Leading Edge Erosion (LEE)

A separate simulation framework trains ML models for classifying LEE.


Detect and classify structural faults

Various models can be applied directly to aerodynamic pressure time series data to detect structural faults


Reconstruct flowfields

For a snapshot of the pressure distribution around an airfoil, determine the surrounding steady pressure and velocity fields. At the same time, determine free stream conditions (velocity, turbulence, AoA)

How it was developed

Aerosense is based on the technology developed within the BRIDGE Discovery project «Aerosense»*, which finished on 30.04.2023. The project was lead by Sarah Barber at the Eastern Switzerland University of Applied Sciences (OST), one of our Scientific Advisory Board members.
