Analysis of Rotor Configuration and Ground Proximity Effects on Hover Download

Abstract
The impact of hover download on rotorcraft design has long been recognized, though analytical focus on the issue has been intermittent, for both technical and programmatic reasons. Advanced models employed on high performance computer systems have shown impressive ability to capture observed behavior, though physics-based tools better suited to routine early stage design analysis are highly desirable. Prior papers conducted an initial assessment the ability of several contemporary “mid-fidelity” analysis tools to compute download and rotor/airframe interaction on helicopters and compound rotorcraft in hover, with initial studies focusing on single rotor aircraft operating out of ground effect. This paper extends this work to the consideration of other rotor configurations (e.g., tiltrotor/side-by-side and coaxial cases); given the development and prospective use of multiple new vehicles featuring these design elements an assessment of this capability is judged timely. In addition, this paper will address the application of these models to the impact of ground proximity on download, an important operational consideration. The major features of airframe download and rotor performance are captured for several representative cases, and observations on differences in predicted and measured performance are discussed.
