Establishing Fluid Dynamics Scales Critical to Dynamic Interface Applications and their Impact on Handling Qualities
Abstract
The goal of this effort is to develop a better understanding of the relationship between the length and time scales typically present in the disturbance fields experienced by Naval aviators (i.e. ship airwakes, wing wakes etc.) and rotorcraft flight dynamics and flying qualities when the fully-interacting fluid dynamics of the disturbance and rotor wake and flight mechanics are accounted for. The effort, which commenced in March 2021 is undertaking the research required to develop such an understanding, along with disseminating the observations and conclusions of the work to the Navy and the broader flight dynamics and handling qualities community. The effort is structured using a build-up approach that first focuses on defining relevant disturbance fields, followed by predicting and understanding the fundamental aeromechanics response (e.g. aerodynamic forces and moments and rotor dynamics), and will culminate in predicting the flight dynamics and flying qualities for realistic, but generic, helicopter and tiltrotor configurations. To date, the effort has focused on investigating the type of disturbance fields experienced by Naval aviators, and how to define the relevant primary flow structures and time scales.
