Helicopter flight in the airwake of non-aviation ships
, 2000 There are problems specific to the helicopter/ship dynamic interface, which limit helicopter operations. Amongst these is the difficulty associated with landing on a moving platform. The ship airwake, which includes large velocity gradients and areas of turbulence, is considered a crucial factor in limiting these operations.

Space-Time Characterization of Ship Airwakes
AIAA Journal, 2023The turbulent airwakes produced by a generic navy frigate (Simple Frigate Ship 2) was investigated in a low-speed wind tunnel. The frigate model was subjected to a headwind and immersed in a simulated atmospheric boundary layer. High-speed stereoscopic particle image velocimetry (PIV) was performed at six different spanwise planes over the flight deck.

Helicopter Aerodynamic Loading in the Airwake of a Moving Ship
Proceedings of the Vertical Flight Society 79th Annual Forum, 2023This paper presents an analysis of the unsteady aerodynamic loading of a helicopter immersed in the airwake of a generic destroyer undergoing several ship motion types: static, sinusoidal pitching, regular 2-DOF, and realistic irregular 3-DOF ship motions. The study was a collaborative effort between the National Research Council Canada and the

Ship Airwake Analysis by CFD Methods
AIP Conference Proceedings, 2007This study is concerned with computational predictions of the highly unsteady turbulent airwake of nonaviation ships. This is the first step in studying complex flow field of fully coupled helicopter/ship interaction. Numerical simulations carried out in this study are performed by using commercial CFD solver CFX 10.0 and FLUENT 6.2.16.

Ship Airwake Sensitivities to Modeling Parameters
43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005** * † Accurate models for the prediction of ship airwake flowfields are critical to the development of realistic flight simulation tools for aircraft carrier launch and recovery operations. The accurate computation of the ship airwake can be very challenging due to the complexity of the ship geometry, the size of and difficulty in generating a ...
