Book Description
The extensive use of composite materials in helicopter structures has prompted new research activities in crashworthiness in the last decade. A rational design of crashworthy structures requires a great deal of data and experience to be collected and organized; in particular the most efficient mechanisms of energy adsorption must be understood and carefully investigated and consequently the best structural concepts an detail design can be identified. With this aim and in cooperation with Augusta Helicopters a research program has been undertaken, covering many of the basic aspects of crashworthy design, i.e. dynamic modeling, design and verification procedures.

Book Description
Although isolated examples of crashworthiness can be found in aircraft which pre-date the designs of the Wright brothers, the first crashworthiness research project was undertaken in 1942 at Cornell University Medical College. The study investigated aircraft crashes to determine the causes of injuries and supported a development program for improving crashworthy design. The aviation industry quickly applied the results of the study, and by the early 1950s, crashworthy design features were incorporated into several airplanes. However, lack of consumer interest forced many of these designs to be dropped. In the 60s and 70s, most of the crashworthiness research pertained to military helicopter design. In the 80s, the lack of crashworthiness standards were seen as one reason for the increase in product liability litigation, bringing on a renewed interest in crashworthy design. In the 90s, aircraft crashworthiness is becoming an increasingly important issue with the push towards zero-tolerance of crashes. In a single source, Aircraft Crashworthiness brings together thirty technical papers which cover the past forty years of progress in this area.These papers were selected because of their significance in the development of crashworthiness technology. Aircraft Crashworthiness will be an ideal addition to the bookshelves of aerospace design engineers, airline industry safety personnel, government administrators, and anyone interested in the impact crashworthy design has on aircraft safety.
Aircraft Crash Survival Design Guide: Aircraft structural crashworthiness

Pages : 17
Book Description
This paper discusses the evolution of crash survival design criteria, its influence on the formulation of a US Army military standard for rotary-wing aircraft crashworthiness, and its application to current and new-generation Army helicopters. Emphasis is given to the need for a total systems' approach in design for crashworthiness and the necessity for considering crashworthiness early in the design phase of a new aviation weapon systems development effort. The actual application of crashworthiness to Army helicopters is presented with statistics that show dramatic reductions in fatalities and injuries with implementation of a crashworthy fuel system. Current and planned US Army R & D to improve crashworthiness technology is discussed, including full-scale crash testing, human tolerance definition, improved energy absorbers, crew restraint systems, and crash impact characteristics of composite helicopter structures. Applicability of the work within Army helicopter crashworthiness to commercial/ civil helicopters is shown. The cost effective aspects of designing helicopters to be more crash survivable are also discussed.

Pages : 624
Book Description
A systematic treatment of current crashworthiness practice in the automotive, railroad and aircraft industries. Structural, exterior and interior design, occupant biomechanics, seat and restraint systems are dealt with, taking account of statistical data, current regulations and state-of-the-art design tool capabilities. Occupant kinematics and biomechanics are reviewed, leading to a basic understanding of human tolerance to impact and of the use of anthropometric test dummies and mathematical modelling techniques. Different types of restraining systems are described in terms of impact biomechanics. The material and structural behaviour of vehicle components is discussed in relation to crash testing. A variety of commonly used techniques for simulating occupants and structures are presented, in particular the use of multibody dynamics, finite element methods and simplified macro-elements, in the context of design tools of increasing complexity, which can be used to model both vehicles and occupants. Audience: An excellent reference for researchers, engineers, students and all other professionals involved in crashworthiness work.
