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.

The aim of this book is to briefly present modern optical measurement techniques to measure the thermal and flow parameters in-flight. Furthermore, advanced optical methods to measure the deformation of the surface of wings and rotor blades of aircraft will be presented. Readers will gain knowledge as a result of research conducted in the framework of the two European projects AIM and AIM2 and verified during the flight test on various types of aircraft. These have included the Evektor VUT100, Airbus A380, Dornier 228, Fairchild Metro II, Janus, PW-6, Piaggio P180 and Scottish Aviation Bulldog.

The demands for higher performance for modern aircraft have led the wind tunnel community, which is an integral link in the design process, to develop more refined and cost effective measuring techniques. These technologies have gradually matured from laboratory novelties into instruments regularly used in aerodynamic testing. The development of these modern measurement techniques has greatly extended the capability and accuracy of the classical methods for measurement techniques and provided better insight into flow physics. This Symposium provided a forum for active researchers to address the state-of-the-art, to exchange experiences and ideas, and for the practitioners to obtain an overview of the technology and learn how to appy it.

With the demand for more advanced fighter aircraft, relying on unstable flight mechanical characteristics to gain flight performance, more focus has been put on model-based system engineering to help with the design work. The flight control system design is one important part that relies on this modeling. Therefore, it has become more important to develop flight mechanical models that are highly accurate in the whole flight envelope. For today’s modern fighter aircraft, the basic flight mechanical characteristics change between linear and nonlinear as well as stable and unstable as an effect of the desired capability of advanced maneuvering at subsonic, transonic and supersonic speeds. This thesis combines the subject of system identification, which is the art of building mathematical models of dynamical systems based on measurements, with aeronautical engineering in order to find methods for identifying flight mechanical characteristics. Here, some challenging aeronautical identification problems, estimating model parameters from flight-testing, are treated. Two aspects are considered. The first is online identification during flight-testing with the intent to aid the engineers in the analysis process when looking at the flight mechanical characteristics. This will also ensure that enough information is available in the resulting test data for post-flight analysis. Here, a frequency domain method is used. An existing method has been developed further by including an Instrumental Variable approach to take care of noisy data including atmospheric turbulence and by a sensor-fusion step to handle varying excitation during an experiment. The method treats linear systems that can be both stable and unstable working under feedback control. An experiment has been performed on a radio-controlled demonstrator aircraft. For this, multisine input signals have been designed and the results show that it is possible to perform more time-efficient flight-testing compared with standard input signals. The other aspect is post-flight identification of nonlinear characteristics. Here the properties of a parameterized observer approach, using a prediction-error method, are investigated. This approach is compared with four other methods for some test cases. It is shown that this parameterized observer approach is the most robust one with respect to noise disturbances and initial offsets. Another attractive property is that no user parameters have to be tuned by the engineers in order to get the best performance. All methods in this thesis have been validated on simulated data where the system is known, and have also been tested on real flight test data. Both of the investigated approaches show promising results.
