Available in PDF, EPUB and Kindle. Book excerpt: Crashworthiness of an aircraft fuselage and its structural components was investigated experimentally and numerically in this study. A finite element model developed previously for simulating the drop test of a 3m long Boeing 737 fuselage section was used to evaluate the effect of the friction coefficient between the fuselage and the ground, and of the aircraft's angle of impact on the dynamic response of the structure. The 3m section model was subsequently expanded to a full-length fuselage model representing a narrow-body transport aircraft in order to simulate realistic crash-landing scenarios on different terrains (i.e., rigid, soil, and water). The results from these studies highlighted the importance of the subfloor structure and its components in the energy absorption process during a crash landing, as well as the need for energy absorbing devices, integrated with the subfloor structure, to mitigate the impact energy. A comprehensive experimental study was performed to investigate the energy absorbing capabilities of graphite/epoxy members that could serve as stanchions in the subfloor structure of aircraft or rotorcraft. First, tubes of circular cross sections with chamfered-ends, inward-folding and outward-splaying crush-caps, and combined (chamfered-end and crush-cap) failure trigger mechanisms, were investigated. Next, members with open cross-sections (C-channels, angle-stiffeners, and hat-stiffeners) with chamfered-ends and steeple failure trigger mechanisms were investigated. The optimal configuration that resulted in the lowest initial peak load while providing the highest possible specific energy absorption (SEA) was identified. Finite element models were developed to simulate the crushing behavior of the graphite/epoxy members observed experimentally using two different modeling methodologies. First, an existing single-layer approach was utilized that required careful calibration of key parameter values used in defining the contact/penetration behavior and material failure. This approach predicted the initial failure peak load and the load-crosshead displacement curve but provided no insight into the failure process. Next, a multi-layer modeling methodology was developed by determining the most effective laminate configuration, element size and formulation, contact definitions, time step control, delamination interface, and material model. This approach captured the failure process and predicted the sustained crush load quite accurately. Such modeling could thus support the future design of aircraft stanchions.

Volume III contains information on the design of aircraft structures and structural elements for improved crash survivability. Current requirements for structural design of U.S. Army aircraft pertaining to crashworthiness are discussed. Principles for crashworthy design are presented in detail for the landing gear and fuselage subject to a range of crash conditions, including impacts that are primarily longitudinal, vertical, or lateral in nature and those that involve more complicated dynamic conditions, such as rollover. Analytical methods for evaluating structural crashworthiness are described.

Book Synopsis Concepts in Fail-safe Design of Aircraft Structures by : David Broek
Download or read book Concepts in Fail-safe Design of Aircraft Structures written by David Broek and published by . This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to obtain an appraisal of the state of the art of fail-safe design, the author made an investory of fail-safe design methods applied by various aerospace companies and of research work relevant to the engineering approach of fatigue-crack propagation and residual strength. This memorandum is based on information from discussions with personnel of several companies and research laboratories, with the main emphasis on plane stress and transitional fracture behavior. The memorandum presents a brief description of the general approach to the fail-safe problem, an analysis of several of the existing methods that use this approach, including their shortcomings, and a summary of the data required for a good fail-safe design. A specific approach proposed for the presentation in MIL-HDBK-5 of data pertinent to the fail-safe design concept is evaluated in terms of its applicability to that concept. (Author).

Book Synopsis Analysis of Aircraft Structures by : Bruce K. Donaldson
Download or read book Analysis of Aircraft Structures written by Bruce K. Donaldson and published by Cambridge University Press. This book was released on 2008-03-24 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with the first edition, this textbook provides a clear introduction to the fundamental theory of structural analysis as applied to vehicular structures such as aircraft, spacecraft, automobiles and ships. The emphasis is on the application of fundamental concepts of structural analysis that are employed in everyday engineering practice. All approximations are accompanied by a full explanation of their validity. In this new edition, more topics, figures, examples and exercises have been added. There is also a greater emphasis on the finite element method of analysis. Clarity remains the hallmark of this text and it employs three strategies to achieve clarity of presentation: essential introductory topics are covered, all approximations are fully explained and many important concepts are repeated.
