Windmilling tests

Greater safety for aeronautical equipment

Why carry out windmilling tests?

Windmilling tests are essential for simulating the free rotation conditions of a turbine with a torn-off blade. These tests make it possible to :

Assess the vibrations induced in the event of a component failure.
Validate the strength of equipment structures subjected to high-amplitude, low-frequency vibrations.
Identify potential mechanical weaknesses under conditions of free rotation.
Optimise the safety and reliability of aircraft
