A Preliminary Study of the Airwake Model Used in an Existing SH-60B/FFG- 7 Helicopter/Ship Simulation Program

Abstract

The ship airwake model in a SH-60B/FFG-7 helicopter/ship simulation program is studied in detail. The airwake model is based on wind tunnel measurements obtained for another ship type, with geometric scaling applied to make it suitable for an FFG-7 frigate. Velocities over the flight deck of an FFG-7, predicted using the program, are compared with those obtained from full- scale tests on HMAS Darwin. Differences between predicted and measured velocities are often found to occur, indicating that the model used for prediction should be based on measurements for an FFG-7.
