2020年10月31日 · A first principles physics-based simulation framework that accounts for wind-over-deck (WOD) and ground effects during approach and landing of a helicopter on a ship deck is developed. The WOD velocities are obtained from unsteady detached-eddy simulation of the flow over a simple frigate shape version 2 ship.

relative positions of the helicopter landing gears and the ship deck and modelling the forces and force moments acting on landing gears when the helicopter impacts against the ship deck. This paper describes a method to establish a landing model that has been applied in …

Helicopter landings and takeoffs on ships are complex operations that require careful planning, precise execution, and strict adherence to safety protocols. The design of the helicopter deck, the skill of the pilots and crew, and the consideration of various factors contribute to the success of these operations.

The following is a detailed procedure on how to analyze helicopter-handling decks for US Navy ships. This paper is a guide to Design Data Sheet DDS 130-2 (Naval Sea Systems Command, 1984). DDS 130-2 is the standard analysis method set by the Naval Sea Systems Command (NAVSEA) to certify ships for operations with helicopters. This guide discusses

landing procedure of the helicopter on the moving, confined ship deck is composed of three stages. Starting from approach to the ship, next hover over the landing deck and final landing with touchdown. During approach, helicopter performs the flight toward the ship’s deck using navigation waypoints. Next,

Landing Area: The deck is typically a flat, open area with a designated landing zone. The size and configuration of the landing zone vary depending on the type of helicopter and the ship's purpose. Landing Lights: Powerful lights illuminate the landing zone, providing visibility for the pilot during night operations.

2020年1月5日 · A first principles physics-based simulation capability that accounts for wind-over-deck (WOD) and ground effect is developed and used to examine the influence of level, inclined and moving decks on helicopter response during hover and landing on the ship.

For a ship having a nominal 25 foot deck height above water, transitioning from a hover 35 feet above water to 10 feet above a solid deck surface produces a noticeable change in hover power required. During heaving sea conditions with the landing deck moving several feet up and down, the helicopter must pick a power setting that

2023年3月29日 · In this study, we examined whether deck-landing decision-making, involving a system composed of a helicopter with a bounded action capabilities and a light, 150 m-long ship of the frigate...
