An Investigation of Ship Airwakes by Scale Adaptive Simulation [PDF]
TransNav, 2020 An early assessment of the ship airwakes flow characteristic is one of the most challenging tasks associated with the designing of vessels. The presence of ship airwake creates very complex flow phenomena due to the presence of strong velocity gradients ...

The Numerical Simulation of UAV's Landing in Ship Airwake [PDF]
Xibei Gongye Daxue Xuebao, 2019 In order to investigate the influence of ship airwake on aerodynamic characteristics of the carrier-based aircraft, UAV's landings in different winds over deck were simulated by Overset Mesh method. Firstly, mesh factors, steady and unsteady methods were

Combined numerical and experimental simulations of unsteady ship airwakes [PDF]
Computers & Fluids, 2018 To aid pilot training for shipboard helicopter operations, computational fluid dynamics (CFD) is increasingly being performed to model ship airwakes. The calculated velocity field data are exported to the flight simulator as look-up tables.

Turbulent Airwake Estimation from Helicopter–Ship Wind-Tunnel Data [PDF]
Journal of AircraftThis paper presents a stochastic approach for modeling the turbulent airwake suitable for real-time simulation of the helicopter–ship dynamic interface. This approach relies on the measurements of unsteady loads collected during a wind-tunnel test campaign with a scaled helicopter operating over the deck of simple frigate shape 1.

Journal of Marine Science and Engineering, 2022 Landing a helicopter to the ship flight deck is most demanding even for the most experienced pilots and modeling and simulation of the ship-helicopter dynamic interface is a substantially challenging technical problem. In this paper, a coupling numerical

Implicit large eddy simulation of ship airwakes [PDF]
The Aeronautical Journal, 2010 AbstractImplicit large eddy simulations (ILES) of two different Royal Navy ships have been conducted as part of the UK Ship/Air Interface Frame-work project using a recently developed very high order accuracy numerical method. Time-accurate CFD data for fourteen flow angles was produced to incorporate into flight simulators for definition of safe ...

Engineering Applications of Computational Fluid Mechanics, 2021 The coupled rotor/ship flowfield is investigated using the Navier–Stokes solver when the helicopter rotor hovers in the ship’s airwake. The solid rotor model (SRM) and virtual rotor model (VRM) are employed, considering the different types of rotor ...
