Bold ambitions
- To support a groundbreaking aerospace company with their understanding of the complex elastic behaviour of their current design with specific reference to the interaction between fuselage and rotor dynamics.
- Increased use of digital twins to support design and certification.
- Due to the novel nature of the aircraft and its potential behaviour, a unique method will be required to firstly understand the aircraft from a vibration perspective.
Reliable solutions
- Creation of the airframe FEM and its integration to the aerodynamic model to yield the aeroelastic model that is used to analyse the aircraft in various conditions. Using in-house tools and of MSC/Nastran
- Vibration analysis intended to assess the zonal vibration spectra to ensure a safe flight will be carried out based on an unvalidated model under a limited set of operating conditions.
- A series of analysis cases assembled to combine harmonic loads for asynchronous rotors, each with frequency content related to its respective rotational speed. The aircraft configurations include the range of states between its VTOL configuration through transition to forward flight.
- The series of analysis cases generated to represent various combinations of rotor speeds, assuming these are controlled independently of one another. Combinations of rotor speed selected to provide resonant excitation of airframe normal modes due to beating frequencies of asynchronous rotors.

Client benefits
- Recommendations for further model validation, rotor loads testing or operational vibration measurements on the GVT and demonstrator aircraft.
- Assist in the establishment of best practices for test activities to avoid problematic conditions, highlight any safety issues and any opportunities to maximise value gained from tests.
