This book was released on 1987 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern high performance aircraft designs tend to employ very thin airfoils having a degree and a distribution of stiffness far from the ideal; in consequence, there is a loss of control effectiveness and maneuverability. Moreover, the introduction of the highly forward-swept-wing planform poses a static aeroelastic effect of fundamental importance; these effects are felt at model as well as at full scale. This meeting was organized not only to review instances of these problems but to see how successfully modern tools for structural and aeroelastic analysis can be applied. The individual papers of the meeting cover many aspects of static aeroelasticity not only for military aircraft but also for modern transport aircraft. The various papers also address problems and recent progress in wind tunnel model testing, in particular measurement of static deformations on wind tunnel models. Keywords: Flutter, Supercritical wings, Aerodynamic loading, Jet fighters, Aerodynamic trim, Symposia, Maneuverability, Sweptforward wings, Aeroelasticity, Aerostatics, Structural analysis, Military aircraft, Transport aircraft, Wind tunnel models.

This book was released on 1986 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Secondary effects in static aeroelasticity that heretofore have been regarded as negligble include: redistribution of induced drag; dihedral effect under load factor; structural axis rotations in equations of motion; aeroelastic divergence of an unrestrained vehicle; and corrections to measurements on 'rigid' wind tunnel model. The few publications on these topics that have appeared over the years are surveyed on the assumption that secondary effects on earlier designs may have become primary effects of future configurations.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Aircraft Aeroelasticity and Loads, SecondEdition is an updated new edition offering comprehensivecoverage of the main principles of aircraft aeroelasticity andloads. For ease of reference, the book is divided into three partsand begins by reviewing the underlying disciplines of vibrations,aerodynamics, loads and control, and then goes on to describesimplified models to illustrate aeroelastic behaviour and aircraftresponse and loads for the flexible aircraft before introducingsome more advanced methodologies. Finally, it explains howindustrial certification requirements for aeroelasticity and loadsmay be met and relates these to the earlier theoretical approachesused. Key features of this new edition include: Uses a unified simple aeroelastic model throughout thebook Major revisions to chapters on aeroelasticity Updates and reorganisation of chapters involving FiniteElements Some reorganisation of loads material Updates on certification requirements Accompanied by a website containing a solutions manual, andMATLAB® and SIMULINK® programs that relate to the modelsused For instructors who recommend this textbook, a series oflecture slides are also available Introduction to Aircraft Aeroelasticity and Loads, SecondEdition is a must-have reference for researchers andpractitioners working in the aeroelasticity and loads fields, andis also an excellent textbook for senior undergraduate and graduatestudents in aerospace engineering.

Download or read book Static Aeroelastic Effects on the Flutter of a Supercritical Wing written by and published by . This book was released on 1987 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that wings with supercritical airfoils generally have lower transonic flutter speeds than similar wings with conventional airfoils and that small increases in angle of attack from zero and the accompanying static aeroelastic deformations have further detrimental effects on transonic flutter. This paper presents results of an effort to calculate the effects of angle of attack and the associated aeroelastic deformation on the flutter of a highly swept supercritical wing (TF-8A) by use of modified strip analysis. The spanwise distributions of steady-state section life-curve slope and aerodynamic calculations for as input for these calculations were obtained from static aeroelastic calculations for the wing by use of hte FL022 transonic code and an assumed dynamic pressure. The process is iterative so that flutter can be obtained at the same dynamic pressure as that used to calculate the statically deformed shape and loading about which the flutter oscillation occurs (matched conditions). Investigation results show that the unconventional backward turn of the transonic dip in the experimental flutter boundary for angles of attack greater than zero is caused by variations in mass ratio and not by static aeroelastic deformation, although inclusion of the latter appears to be required for quantitative accuracy in the calculations. For the very high subsonic Mach numbers of this investigation, quantitative accuracy will also require inclusion of viscous effects on shock strength and location.

This book was released on 2002-07-01 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeroelastic and structural dynamic phenomena play an important role in many facets of engineering. In particular, an understanding of these disciplines is essential to the design of aircraft and space vehicles. This text provides an introduction to structural dynamics and aeroelasticity, with an emphasis on conventional aircraft. The primary areas considered are structural dynamics, static aeroelasticity, and dynamic aeroelasticity. The structural dynamics material emphasizes vibration, the modal representation, and dynamic response. Aeroelastic phenomena discussed include divergence, aileron reversal, airload redistribution, unsteady aerodynamics, flutter, and elastic tailoring. Both exact and approximate solution methodologies are stressed. More than one hundred illustrations and tables help clarify the text, while upwards of fifty problems enhance student learning.

Available in PDF, EPUB and Kindle. Book excerpt: The paper first describes results of static aeroelastic calculations for a recent canard/cranked delta fighter project, in which a complete aircraft aerodynamic and structural model is used to demonstrate full-interacted 'free' aircraft deflection modes and resulting stability effects. The significance of these results is illustrated by comparison with corresponding 'fixed root' calculations, thereby indicating a requirement for complete aircraft aeroelastic modelling at the earliest possible stage in project design. Aeroelastic modelling of external stores in the context of store/aircraft integration is also discussed. Finally, the correction of high-speed wind-tunnel model results for aeroelastic distortion is addressed, indicating those parameters which are likely to be significantly affected.
