Flight flutter testing is mandatory for aircraft certification; however it is a risky, lengthy and costly process with ever-growing demand for shorter and cheaper as well as online testing tools. This research has dealt with two key issues and the methods developed have been validated on simulated aeroelastic data sets. Firstly, the flutter boundaries are evaluated using statistical confidence criteria based on Least Squares statistics and eigenvalue perturbation theory rooting from noise statistics in the response data from a single flight test outdoing the need for Monte Carlo simulations or repeated tests. The approach is employed on three different flutter prediction tools: Damping Extrapolation method, Flutter Margin method and Envelope Function method. Results from the first two methods showed widening of the confidence bounds with increasing noise whilst the third method remained robust to it. The other research problem involves the development of an online flutter prediction tool using the Envelope Function method. The original approach is extended by making direct use of the chirp response to predict the flutter speed and is applicable to both offline and online versions.

The book presents a synopsis of the main results achieved during the 3 year EU-project "Advanced Inflight Measurement Techniques (AIM)" which applied advanced image based measurement techniques to industrial flight testing. The book is intended to be not only an overview on the AIM activities but also a guide on the application of advanced optical measurement techniques for future flight testing. Furthermore it is a useful guide for engineers in the field of experimental methods and flight testing who face the challenge of a future requirement for the development of highly accurate non-intrusive in-flight measurement techniques.

This book contains 71 papers presented at the symposium on “Recent Advances in Experimental Mechanics” which was organized in honor of Professor Isaac M. Daniel. The symposium took place at Virginia Polytechnic Institute and State University on th June 23-28, 2002, in conjunction with the 14 US National Congress of Applied Mechanics. The book is a tribute to Isaac Daniel, a pioneer of experimental mechanics and composite materials, in recognition of his continuous, original, diversified and outstanding contributions for half a century. The book consists of invited papers written by leading experts in the field. It contains original contributions concerning the latest developments in experimental mechanics. It covers a wide range of subjects, including optical methods of stress analysis (photoelasticity, moiré, etc.), composite materials, sandwich construction, fracture mechanics, fatigue and damage, nondestructive evaluation, dynamic problems, fiber optic sensors, speckle metrology, digital image processing, nanotechnology, neutron diffraction and synchrotron radiation methods. The papers are arranged in the following nine sections: Mechanical characterization of material behavior, composite materials, fracture and fatigue, optical methods, n- destructive evaluation, neutron diffraction and synchrotron radiation methods, hybrid methods, composite structures, and structural testing and analysis.
