A Residual PPO Method for Shipboard Helicopter Landing Control
AerospaceShipboard helicopter landing in the near-deck region requires stable attitude regulation and high-precision deck-relative motion control under substantial model uncertainty and environmental disturbances, conditions under which conventional model-based ...

An Investigation of Frigate Ship Airwakes by RANS Modelling
, 2021 The operation of helicopters on-board ships has always been a very complex task owing to the presence of ship air wakes, high velocity gradients, widely varying turbulence length scales as well as the lesser area provided for helicopter operations.

Isolated rotor engagement and disengagement simulations in ship airwake
, 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 ...
