Isolated rotor engagement and disengagement simulations in ship airwake [PDF]
, 2016 During the engagement and disengagement phases of maritime helicopter operations, a transient aeroelastic phenomenon can occur, known as blade sailing. Characterised by large blade def lections, which have the potential to cause structural damage to the aircraft, blade sailing can limit the tactical flexibility of a helicopter operating in a maritime ...
