Abstract
The aerodynamic performance of aero-structures made of intrinsically smart
materials, such as aeroelastic tailored wings and blades, cannot be obtained
unless their material properties and structural characteristics are also known. The
aerodynamic design of these structures is a naturally integrated design problem
in which the set of design parameters comprises both aerodynamic and structural
characteristics of the aero-structure. This paper references the inevitable
problems arising when adopting an integrated design approach, suggesting an
alternative approach for design of these structures. The concept of Variable State
Design Parameters (VSDP) is introduced in this paper and it is explained how
VSDP can be employed to convert the traditional integrated design process of
intrinsically smart aero-structures, to a decoupled and hence computationally
efficient design process. Through a design case study the practicality and
efficiency of the new approach have been demonstrated.
Keywords: Variable State Design Parameter, smart structures, elastic coupling,
aeroelastic tailoring, deign decoupling.
1 Introduction
The advent of smart materials has made the idea of shape-changing aerodynamic
structures practical. Many research projects on using smart materials to control
the shape of wings have been reported in the last decade, for instance see [1–4].
Simultaneously rotor blades made of smart materials have found many practical
