Available in PDF, EPUB and Kindle. Book excerpt: A full-scale crash test of the Sikorsky Advanced Composite Airframe Program (ACAP) helicopter was performed in 1999 to generate experimental data for correlation with a crash simulation developed using an explicit nonlinear, transient dynamic finite element code. The airframe was the residual flight test hardware from the ACAP program. For the test, the aircraft was outfitted with two crew and two troop seats, and four anthropomorphic test dummies. While the results of the impact test and crash simulation have been documented fairly extensively in the literature, the focus of this paper is to present the detailed occupant response data obtained from the crash test and to correlate the results with injury prediction models. These injury models include the Dynamic Response Index (DRI), the Head Injury Criteria (HIC), the spinal load requirement defined in FAR Part 27.562(c), and a comparison of the duration and magnitude of the occupant vertical acceleration responses whole-body acceleration tolerance curve.

Download or read book The Cambridge Aerospace Dictionary written by Bill Gunston and published by Cambridge University Press. This book was released on 2011-02-14 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Aerospace Dictionary is an authoritative and accessible reference useful to scholars and enthusiasts alike. This dictionary is an essential tool for professionals involved in the aerospace industry and flight, and for anyone who must read and understand the technical literature of the aerospace industry and about specific air and space craft. It is also an ideal reference for engineering and physics students encountering a subject replete with technical jargon and acronyms. Bill Gunston, one of the most widely read and respected aviation writers, has added more than 5,000 new terms and acronyms to this carefully updated volume. Terms used in the dictionary reflect the diverse and international nature of the aerospace industry and include brief explanations of aerospace materials and organizations. Gunston has scrupulously avoided terms specific to manufacturers, airlines, and armed forces in an effort to encourage clear communication and understanding among professionals.

This book was released on 2018-06-15 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A full-scale crash test of a prototype composite helicopter was performed at the Impact Dynamics Research Facility at NASA Langley Research Center in 1999 to obtain data for validation of a finite element crash simulation. The helicopter was the flight test article built by Sikorsky Aircraft during the Advanced Composite Airframe Program (ACAP). The composite helicopter was designed to meet the stringent Military Standard (MIL-STD-1290A) crashworthiness criteria and was outfitted with two crew and two troop seats and four anthropomorphic dummies. The test was performed at 38-ft/s vertical and 32.5-ft/s horizontal velocity onto a rigid surface. An existing modal-vibration model of the Sikorsky ACAP helicopter was converted into a model suitable for crash simulation. A two-stage modeling approach was implemented and an external user-defined subroutine was developed to represent the complex landing gear response. The crash simulation was executed with a nonlinear, explicit transient dynamic finite element code. Predictions of structural deformation and failure, the sequence of events, and the dynamic response of the airframe structure were generated and the numerical results were correlated with the experimental data to validate the simulation. The test results, the model development, and the test-analysis correlation are described. Jackson, Karen E. and Fasanella, Edwin L. and Boitnott, Richard L. and Lyle, Karen H.

Book Synopsis Riveted Lap Joints in Aircraft Fuselage by : Andrzej Skorupa
Download or read book Riveted Lap Joints in Aircraft Fuselage written by Andrzej Skorupa and published by Springer Science & Business Media. This book was released on 2012-06-23 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.
