AIRCRAFT loss of control (LOC) remains one of the largest contributors to fatal accidents. As
shown in Fig. 1, in-flight loss of control was the largest fatal accident category for large …

The paper details the research and corresponding implementation and testing steps of the
FLEXOP demonstrator aircraft. Within the EU funded project an unmanned demonstrator …

The fuel efficiency of future aircraft can be improved by reducing the weight and structure
and by increasing the wingspan. This makes the aircraft structure more flexible and results in …

In order to update the finite element model, the modal test results must be highly accurate
since they are used as the basis. The major problems with traditional modal test method are …

Aiming at the experimental test of the body freedom flutter for modern high aspect ratio
flexible flying wing, this paper conducts a body freedom flutter wind tunnel test on a full-span …

As aircraft wings become more flexible as a result of searching for more fuel efficient and
higher performance solutions, structural nonlinearities become more apparent. Geometric …

The dynamics of a flexible air vehicle are typically described using an aeroservoelastic
model which accounts for interaction between aerodynamics, structural dynamics, rigid body …

This paper presents an overview of Dr. Gary Balas research activities in linear, parameter-
varying (LPV) systems applied to aeroservoelastic (ASE) aircraft. More efficient aircraft can …

Finite element models have been used in many applications in aerospace, civil and
mechanical engineering for accurate response predictions for the product design. In the …

The finite element based structural model of a flexible wing is presented. The structural
model will be a part of a servoelastic wing used for flutter analysis and designing flutter …
