A new class of frequency-selective shock absorbers called band-pass shock absorbers which were conceived as a means of overcoming some of the limitations of conventional shock absorbers is described. These shock absorber designs are introduced, special emphasis being given to their use in landing and taxiing problems of high-speed aircraft. For such aircraft operated on rough land or water runways, conventional oleo struts approach a rigid condition for bum[s with steep slopes and thereby develop and transmit severe shock loads to the aircraft fuselage. The operation of the band-pass shock absorbers in the reduction of loads in certain selected frequency ranges is described. Theoretical equations are derived and solutions are made for several cases for the purpose of comparing the low-pass and conventional shock-absorber actions. The results indicate that the band-pass shock absorbers should alleviate high-frequency or rapidly applied impact loads but should retain the characteristics of conventional oleo struts when taxiing and design landing loads are slowly applied. A number of variations in design are presented for low-pass shock absorbers and reference is made to double-acting band-pass vibration absorbers for other applications.

A comprehensive approach to the air vehicle design processusing the principles of systems engineering Due to the high cost and the risks associated with development,complex aircraft systems have become a prime candidate for theadoption of systems engineering methodologies. This book presentsthe entire process of aircraft design based on a systemsengineering approach from conceptual design phase, through topreliminary design phase and to detail design phase. Presenting in one volume the methodologies behind aircraftdesign, this book covers the components and the issues affected bydesign procedures. The basic topics that are essential to theprocess, such as aerodynamics, flight stability andcontrol, aero-structure, and aircraft performance are reviewedin various chapters where required. Based on thesefundamentals and design requirements, the author explains thedesign process in a holistic manner to emphasise the integration ofthe individual components into the overall design. Throughout thebook the various design options are considered and weighed againsteach other, to give readers a practical understanding of theprocess overall. Readers with knowledge of the fundamental concepts ofaerodynamics, propulsion, aero-structure, and flight dynamics willfind this book ideal to progress towards the next stage in theirunderstanding of the topic. Furthermore, the broad variety ofdesign techniques covered ensures that readers have the freedom andflexibility to satisfy the design requirements when approachingreal-world projects. Key features: • Providesfull coverage of the design aspects of an air vehicle including:aeronautical concepts, design techniques and design flowcharts • Featuresend of chapter problems to reinforce the learning process as wellas fully solved design examples at component level • Includes fundamental explanations for aeronautical engineeringstudents and practicing engineers • Features a solutions manual to sample questions on the book’scompanion website Companion website - ahref=""

Landing gear weight calculations can be carried out using statistical or analytical methods. Statistical methods were used in the past and offered quick group weights. However, they are not capable of computing accurately the weight of landing gears, which have special geometries and performance. In this work, landing gear weight is computed using analytical methods based on parametric 3D models. The procedure established by Kraus and Wille is applied as a baseline so as to create a procedure capable of dealing with landing gear weight calculations. This method is designed to be as flexible as possible, giving the user the freedom to modify many options and parameters and integrate landing gear design into Robust Aircraft Parametric Interactive Design.

Aircraft performance is influenced significantly both by aeroelastic phenomena, arising from the interaction of elastic, inertial and aerodynamic forces, and by load variations resulting from flight and ground manoeuvres and gust / turbulence encounters. There is a strong link between aeroelasticity and loads, and these topics have become increasingly integrated in recent years. Introduction to Aircraft Aeroelasticity and Loads introduces the reader to the main principles involved in a wide range of aeroelasticity and loads topics. Divided into three sections, the book begins by reviewing the underlying disciplines of vibrations, aerodynamics, loads and control. It goes on to describe simplified models to illustrate aeroelastic behaviour and aircraft response before introducing more advanced methodologies. Finally, it explains how industrial certification requirements for aeroelasticity and loads may be met and relates these to the earlier theoretical approaches used. Presents fundamentals of structural dynamics, aerodynamics, static and dynamic aeroelasticity, response and load calculations and testing techniques. Covers performance issues related to aeroelasticity such as flutter, control effectiveness, divergence and redistribution of lift. Includes up-to-date experimental methods and analysis. Accompanied by a website with MatLAB and SIMULINK programs that relate to the models used. Introduction to Aircraft Aeroelasticity and Loads enables the reader to understand the aeroelastic and loads principles and procedures employed in a modern aircraft design office. It will appeal to final year undergraduate and masters students as well as engineers who are new to the aerospace industry.
