Abstract

Fluid Actuated Morphing Unit Structures (FAMoUS) are orthotropic structure-actuation units that elongate upon fluid pressurization. These unit structures are composed of reinforced elastomeric chambers and their development is motivated by their allowable integration in tight spaces and potential high work output, thereby enabling morphing in thin wing regions. This presentation will show results from manufacturing and laboratory testing of small prototypes, which are being used for fine-tuning finite element models for the purpose of designing a FAMoUS morphing winglet demonstrator which is to be subsequently manufactured. The finite element modelling features nonlinear hyperelastic material models using experimental data and hydrostatic fluid elements which provide information for the fluidic systems design, such as overall architecture, sizing of pumps etc. Mass and stiffness information are also determined which are used for investigating aeroelastic characteristics of the control surface. Aspects of control are also investigated in this work whereby fiber optic shape sensors are used for monitoring control surface deflection and are to be integrated with the fluid pumps to provide closed-loop control. This is a necessary feature since the internal fluid pressure state needs to be adapted to changing external loading conditions in order to hold a given setpoint. Progress on the multidisciplinary aspects as mentioned above will be presented in this talk.
