ROTOR/WING INTERACTION

Obiettivo

The project covers the experimental and numerical investigation of some flow phenomena related to the interactive functional behaviour of the propeller-nacelle-wing configuration for various rotorcraft concepts. This combined study aims at:
The improvement of the understanding of the dominant physical processes (wake-body interaction, propulsion system-wing-fuselage interaction, vortex blade-interaction, etc).
The provision of computation codes capable of predicting reliably the load distributions on the various components of the airframe configuration.
The operation of multi-component configurations operating in strong interaction was considered. The specific configurations included a rotor mounted together with its nacelle on a wing. By inclining the rotor axis with respect to the plane of the wing different flow situations were generated that correspond to the flows developed around tilt-rotor aircrafts and helicopters. These flow situations have been investigated both numerically and experimentally giving valuable information. Among the various physical characteristics, special attention was given to the intense vortex interactions that take place between the wake of the rotor and the wing. As regards the experimental part of the work, steady and unsteady measurements were taken providing a complete data base. In particular apart from the local and global loading characteristics, three-dimensional velocity measurements as well as tracing of the top vortices of the rotor were performed. These measurements were compared with numerical predictions obtained by means of aerodynamic models of varying complexity. This evaluation task showed that reasonably accurate results can be obtained even if viscous effects are neglected.
The propeller-nacelle-wing configuration will be considered in conventional and convertible form. In the experimental part of the project, extensive wind tunnel tests will be performed including measurements of the local and global aerodynamic coefficients, 3-dimensional velocity measurements, circulation measurements on the rotor blades and vortex trajectory measurements.

The experimental methods to be used include measurements with strain gauges, hot wires, pressure transducers and laser anemometry, as well as flow visualization techniques of various types. In the numerical part of the project, several grid-free methods of boundary element type and of varying complexity will be used. The simpler are based on the equilibrium of the propeller wake, whereas the more elaborate approximate the full unsteady non-linear equations using the vortex particle approach.
