Abstract

Piloted simulation tests were conducted to evaluate advanced response types for ship-based rotorcraft. The simulation used the GENHEL-PSU model of an UH-60 operating from a FFG-7 frigate. The Control Equivalent Turbulence Input (CETI) model was used for airwake turbulence. A full-authority nonlinear dynamic inversion control law was designed to provide attitude command/attitude hold (ACAH), acceleration command/velocity hold (ACVH), and translational rate command/position hold (TRC/PH) response types. Ship deck motion measurements were fed into these control laws to provide ship-relative control. Piloted evaluations were performed for each response type as well as the baseline mechanical control system. A maritime mission task element was performed with and without ship motion and airwake effects. Pilot comments, handling qualities ratings, and workload metrics indicated that the best performance was achieved using an ACVH response type on approach, which then automatically transitions to TRC/PH over the ship deck.
