Project 20: Ship Dynamics/Ship Air Wake Interface

Summary of Services Performed: Enhanced ship airwake integration with ship model and flight dynamics model

All previous shipboard rotorcraft analyses were based on the ship airwake variation generated from a steady ship forward motion. This research focused on investigating the effects of unsteady ship motion and the ship airwake generated from that motion on the shipboard rotorcraft flight dynamics. The study showed remarkable effects of the ship motion on the shipboard rotorcraft flight dynamics. An advanced turbulent ship airwake model was derived that reflects the effects of the ship motion. This research also developed modeling technology for the rotor/ship aerodynamic interaction that addresses the unique aerodynamic phenomena under shipboard operational conditions, including partial and dynamic ship deck effects and the interaction of the rotor downwash with the ship airwake. The development of shipboard rotorcraft flight control options can greatly benefit from these advanced modeling features.
