Aerospace Structures

Main content

Our group investigates the exploitation of distributed properties of smart materials and structures in the design of novel adaptive systems.

Our research is concerned with the exploitation of the distributed properties of structural and smart material components for realising novel behaviours in adaptive structures. We optimise the spatial distribution of structural, actuation and sensing materials for achieving an optimal response across a wide range of operational scenarios and tasks. This is obtained following a highly multi-disciplinary design and optimisation methodology, which allows us to fully exploit the potential of adaptive structures and multi-functionality in applications ranging from: morphing structures, energy harvesting, and highly structurally integrated distributed actuation and sensing systems.

Selective Compliance Aerofoils with Variable Stiffness Multi-stable Elements for Morphing Applications
 

A concurrent design and optimisation methodology is developed, aimed at a shape-adaptable solution addressing the conflicting requirements of morphing through the concept of stiffness variability. The distinct stiffness properties of each equilibrium configuration of bi-stable laminates strategically embedded within the distributed topology of compliant aerofoils are exploited to achieve global shape adaptation.
