Abstract:

The report presents the foil and craft characteristics required by the Grumman Specific Linear Optimal Control Program for hydrofoil craft SLOCOP . The characteristics are presented in generalized form, compared with certain experimental measurements, and evaluated for the AGEH. The prediction confidence level is deficient in three significant areas hinge moment, particularly for flaps unsteady loading, particularly for orbital motion and flap cavitation boundaries. SLOCOP trending studies are underway to establish the sensitivity of the autopilot design to the unsteady loading representation employed. These studies are intended to identify those unsteady loading responses for which further experimental effort is required for confident autopilot design.
