Analysis of Aircraft Structures

Author: Bruce K. Donaldson
Publisher: Cambridge University Press
ISBN: 9780521865838
Release Date: 2008-03-24
Genre: Technology & Engineering

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.

Introduction to Structural Dynamics

Author: Bruce K. Donaldson
Publisher: Cambridge University Press
ISBN: 9781139459082
Release Date: 2006-10-23
Genre: Technology & Engineering

This textbook, first published in 2006, provides the student of aerospace, civil and mechanical engineering with all the fundamentals of linear structural dynamics analysis. It is designed for an advanced undergraduate or first-year graduate course. This textbook is a departure from the usual presentation in two important respects. First, descriptions of system dynamics are based on the simpler to use Lagrange equations. Second, no organizational distinctions are made between multi-degree of freedom systems and single-degree of freedom systems. The textbook is organized on the basis of first writing structural equation systems of motion, and then solving those equations mostly by means of a modal transformation. The text contains more material than is commonly taught in one semester so advanced topics are designated by an asterisk. The final two chapters can also be deferred for later studies. The text contains numerous examples and end-of-chapter exercises.

Rotorcraft Aeromechanics

Author: Wayne Johnson
Publisher: Cambridge University Press
ISBN: 9781107355286
Release Date: 2013-04-29
Genre: Technology & Engineering

A rotorcraft is a class of aircraft that uses large-diameter rotating wings to accomplish efficient vertical take-off and landing. The class encompasses helicopters of numerous configurations (single main rotor and tail rotor, tandem rotors, coaxial rotors), tilting proprotor aircraft, compound helicopters, and many other innovative configuration concepts. Aeromechanics covers much of what the rotorcraft engineer needs: performance, loads, vibration, stability, flight dynamics, and noise. These topics include many of the key performance attributes and the often-encountered problems in rotorcraft designs. This comprehensive book presents, in depth, what engineers need to know about modelling rotorcraft aeromechanics. The focus is on analysis, and calculated results are presented to illustrate analysis characteristics and rotor behaviour. The first third of the book is an introduction to rotorcraft aerodynamics, blade motion, and performance. The remainder of the book covers advanced topics in rotary wing aerodynamics and dynamics.

Advanced Aircraft Design

Author: Egbert Torenbeek
Publisher: John Wiley & Sons
ISBN: 9781118568095
Release Date: 2013-05-28
Genre: Technology & Engineering

Although the overall appearance of modern airliners has not changed a lot since the introduction of jetliners in the 1950s, their safety, efficiency and environmental friendliness have improved considerably. Main contributors to this have been gas turbine engine technology, advanced materials, computational aerodynamics, advanced structural analysis and on-board systems. Since aircraft design became a highly multidisciplinary activity, the development of multidisciplinary optimization (MDO) has become a popular new discipline. Despite this, the application of MDO during the conceptual design phase is not yet widespread. Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes presents a quasi-analytical optimization approach based on a concise set of sizing equations. Objectives are aerodynamic efficiency, mission fuel, empty weight and maximum takeoff weight. Independent design variables studied include design cruise altitude, wing area and span and thrust or power loading. Principal features of integrated concepts such as the blended wing and body and highly non-planar wings are also covered. The quasi-analytical approach enables designers to compare the results of high-fidelity MDO optimization with lower-fidelity methods which need far less computational effort. Another advantage to this approach is that it can provide answers to “what if” questions rapidly and with little computational cost. Key features: Presents a new fundamental vision on conceptual airplane design optimization Provides an overview of advanced technologies for propulsion and reducing aerodynamic drag Offers insight into the derivation of design sensitivity information Emphasizes design based on first principles Considers pros and cons of innovative configurations Reconsiders optimum cruise performance at transonic Mach numbers Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes advances understanding of the initial optimization of civil airplanes and is a must-have reference for aerospace engineering students, applied researchers, aircraft design engineers and analysts.

Introduction to Aircraft Design

Author: John P. Fielding
Publisher: Cambridge University Press
ISBN: 9781107393356
Release Date: 1999-10-14
Genre: Technology & Engineering

This book provides an accessible introduction to the fundamentals of civil and military aircraft design. Giving a largely descriptive overview of all aspects of the design process, this well-illustrated account provides an insight into the requirements of each specialist in an aircraft design team. After discussing the need for new designs, the text assesses the merits of different aircraft shapes from micro-lights and helicopters to super-jumbos and V/STOL aircraft. Following chapters explore structures, airframe systems, avionics and weapons systems. Later chapters examine the costs involved in the acquisition and operation of new aircraft, aircraft reliability and maintainability, and a variety of unsuccessful projects to see what conclusions can be drawn. Three appendices and a bibliography give a wealth of useful information, much not published elsewhere, including simple aerodynamic formulae, aircraft, engine and equipment data and a detailed description of a parametric study of a 500-seat transport aircraft.

Release Date: 1988
Genre: Technology & Engineering

This book provides an authoritative and practical presentation of the determination of gust loads on airplanes, especially continuous turbulence gust loads. The text emphasizes the basic concepts involved in gust load determination and enriches the material with discussion of important relationships, definitions of terminology and nomenclature, historical perspective, and explanations of relevant calculations. Coverage begins with discrete-gust idealization of the gust structure and moves to continuous-turbulence gust loads. Also considered are loads combination and design criteria, gust-response equations of motion, spanwise variation of vertical gust velocity, nonlinear systems, and analysis of gust-response flight-test data.
