The EMpEROR platform was born on the one hand, from the increasing consideration of aeroelastic phenomena in modern aeronautics, and on the other hand, from the synergy between the Aerodynamics, Energetics, and Propulsion (DAEP) and Structural Mechanics and Materials (DMSM) departments.
This platform has been designed and thought out to allow great modularity of metrology, around a rotor bench allowing to rotate from 1 to 6 blades, up to 1 meter in diameter, from 0 to 3000 rpm, and this in complete safety thanks to a 6-meter-long protective cage. It is equipped with several sensors for performance measurements, but also with a rotating vibrometry system for measuring the dynamics of the blades (this system is only used by two laboratories in Europe). The bench also makes it possible to embed measurement systems in the blades, but also in the coming months, systems to control these unstable phenomena.
Since 2020, this platform has also enabled two thesis students to work on aeroelastic phenomena, as well as 6 Master’s students. This platform also makes it possible to generate experimental databases used by ISAE-SUPAERO researchers to compare and validate their computer codes.
The equipment will increase in power in 2024 with the addition of the possibility of making Laser measurements, of the PIV or/and LDV type, as well as the possibility of manufacturing more complex blades with the hand on the flexibility of these.
