RC/AG-27 Analysis and Decomposition of the Aerodynamic Force Acting on Rotary Wings

The AG-27 Action Group is dedicated to the analysis and decomposition of aerodynamic forces acting on rotary wings. Coordinated by Cranfield University, the group involves partners from Italy, France and UK. The core objective is to advance force decomposition methods (vortical, momentum-based thermodynamic, and energy/exergy-based) specifically by extending them to unsteady flows and non-inertial reference frames. Participant works on the development of generalized formulations and exergy balance formulations for unsteady flows, and contribution to the theoretical extension of vortical methods to non-inertial frames. The work also includes a unified task to cross-compare these methods, establish mathematical links, and identify opportunities for unification. Ultimately, the group aims to define guidelines and best practices for the aerodynamic assessment of rotary wings.
