Prediction of Shock Motions of a Ship Deck

The Journal of the Acoustical Society of America, 1969
Some problems encountered in predicting shock motions on a ship deck are discussed. Several approaches for determining natural frequencies and mode shapes of a bare deck are compared and evaluated against experimental data. A procedure for predicting natural frequencies and mode shapes of a deck with attached masses is developed and evaluated by ...

THE DESIGN AND HYDRODYNAMIC ASSESSMENT OF A SUBMARINE CONCEPT WITH OFF-AXIS RESOLVING THE IMPACT OF SHIP’S DESIGN ON DECK AND WELL-DECK LAUNCH AND RECOVERY OPERATIONS BY APPLYING OF QUIESCENT PERIOD PREDICTION (QPP)

Warship 2022, 2022
One of the most challenging tasks in the deployment of ship-based manned and unmanned VTOL aviation is the launch and recovery and deck handling operational performance on smaller ship platforms. The same may be said of ship Well-deck-based surface boats,

Launch and Recovery of Traditional VTOL UAVs by Quiescent Period Prediction (QPP), the development of QPP for All Weather Operations (AWOPS)

Proceedings of the Vertical Flight Society 79th Annual Forum, 2023
For most of the traditional VTOL UASs, the precise measurement of these environmental data is essential for air vehicle safe launch and recovery events. Physics limits the speed by which the deck can be raised from rest to a dangerous position.

Autonomous Ship Deck Landing Strategies for Unmanned Rotorcraft Operating in Harsh Weather Conditions

Proceedings of the Vertical Flight Society 81st Annual Forum and Technology Display
Heavy wind and high sea states pose challenges to operating unmanned rotorcraft on-board a naval ship, in particular the recovery phase. A novel autonomous landing strategy for unmanned rotorcraft is proposed and investigated.
