LM Blades

Integrated calculations

LM Blades supports the integrated calculation of aerodynamics, structure, loads and the control system, all in one single tool. This software suite performs much faster and provides a more precise calculation of everything from geometry to finite element analysis. The software optimises the blades in relation to the wind turbine as a whole.

Specially developed

In LM Blades, all information is collected in a single database, and the different calculation modules can communicate with each other. This translates into a consistent dataflow:

• greater precision and more refined calculations
• greater clarity (tracking the design process)
• faster calculations.

More design loops in a shorter time

It used to take several days to calculate the effects of a change of structure (e.g. moving the glass fibre sheets) on the blade. With LM Blades, it now takes just a few minutes. This software enables the user to physically move components such as glass fibre sheets around on screen. The same flexibility applies to changes in geometry, structure, loads, etc.
A global calculation of an entire design now only takes a few hours. LM Blades can calculate more design variations in a shorter time, leaving scope for fine-tuning the relationship between performance and loads. Ultimately, this improves the overall economy of the wind turbine as a whole.

Automatic input to FEM

One unique feature of LM Blades is that it automatically generates input data for FEM (Finite Element) calculations. This is normally a very time-consuming process, and manual entry carries a risk of errors. LM Blades therefore means we can quickly create finite element analyses to verify buckling in the design.
