Abstract This work presents a comprehensive numerical environment, obtained by the coupling of a mid-fidelity aerodynamic solver based on a vortex particle method with a multibody dynamics tool, for aeroelastic simulations suitable for the analysis and design of next-generation rotary-wing aircraft. Indeed, the presence of multiple propellers and rotors, together with interactional aerodynamics, have a strong impact on dynamic loads and performance indexes on rotorcraft. A mid-fidelity approach provides an ideal trade-off between the accuracy of the solution and the speed of execution required in the preliminary design phases of these vehicles. A tiltrotor model representative of the Bell XV-15 with different levels of complexity is proposed as a test benchmark, whose characteristics can be similar to an eVTOL. The coupled solver shows the capability to determine the trim conditions in airplane mode and predicts steady and periodic trim loads. Transient analyses are presented as well, considering a roll maneuver and highlighting the importance of the accurate representation of rotary wing aerodynamics provided by the vortex particle method for load evaluation and vibrational assessment.
