Case Study: a groundbreaking aerospace company improves aircraft vibration understanding with Expleo

Understanding vibration in a novel aircraft

The groundbreaking aerospace company required a deeper understanding of the complex vibration and elastic behavior of its novel aircraft design, specifically focusing on the interaction between the fuselage and rotors. Expleo was engaged to develop a unique method for this analysis to support the design and certification process with digital twins.

Expleo's solution involved creating an aeroelastic model of the airframe and integrating it with an aerodynamic model, using tools including MSC/Nastran. They conducted a series of vibration analyses under various operating conditions to assess safety and identify potential resonant excitations. As a result, Expleo provided critical recommendations for further model validation and testing, helping the client establish best practices to mitigate safety issues and maximize the value of future test activities.
