Download or read book Structural Analysis of Helicopter Flight and Hangar Decks written by and published by . This book was released on 2001 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication clarifies and modernizes the text in the current Design Data Sheet, DDS 130-2, used to analyze the structural strength of US Navy ship helicopter flight and hangar decks. This document explains the DDS 130-2 procedure to provide a better understanding of the methodology. The DDS 130-2 and this document provide a uniform standard and simplified method for the strength analysis of the helicopter flight and hangar deck structure on US Navy Ships. The analysis method is specifically for helicopter operations. Any other loading conditions or aircraft operations in the handling areas should be considered separately. The DDS 130-2 includes helicopter with both wheeled and skid type landing gear, this paper focuses on helicopters with wheeled gears only.

This book was released on 1981 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1976, the David W. Taylor Naval Ship Research and Development Center has been assisting the U.S. Coast Guard in evaluating the strength of several helicopter landing deck configurations for existing 210-foot long cutters and for the new 270-foot cutters. These evaluations were performed based on a combined program of (a) analytical, (b) one-fifth-scale rigid vinyl model, and (c) full-scale investigations for several landing gear load conditions, including the main and tail wheels on the U.S. Navy LAMPS Helicopter. The analytical side of the program included: framing analyses using the finite-element method and other techniques; nonlinear, large-deflection analyses of the deck plating; and web bending analyses in the stiffeners. The web bending stresses referred to here are associated with local out-of-plane bending of the web due to a rotation of the joint between the stiffener web and the deck plating. These web stresses are distinct from those related to ordinary bending of the stiffener in the vertical plane. Web bending stresses in the stiffeners were first observed in full-scale tests on the 210-foot cutter STEADFAST and are not specifically addressed by current design procedures. A one-fifth-scale rigid vinyl model was used to validate the analytical procedures and also to investigate such considerations as load placement, orientation, and tire print geometry.
