Marine aerofoil motion damping and related propulsive benefits

Record type: Monograph (Project Report)

Publication of Japanese operational experience with sail-assisted ships has shown that substantial reduction in roll motion and associated propulsive benefits accrue from the use of sail. It is suggested that there will be cases where these benefits can be used to justify both the lowering of installed engine power and the removal of stabilising tanks from a ship's specification. A method is presented for predicting the roll reduction from an unstalled, rectangular-planform marine aerofoil and the nature of marine aerofoil roll damping is explored. The requirement for roll reduction has implications for the control of a marine aerofoil, which are examined. Evidence for the associated propulsive benefits is reviewed and some possible processes which may produce these benefits are identified.
