In situ phase change characterization of PVDF thin films using Raman spectroscopy
2014
A process for the design and optimization of a morphing aileron using flexible matrix composite (FMC) actuators
is developed. Design requirements were based on the use of a morphing aileron with an existing medium size
commercial transport aircraft limiting the planform to the existing conventional aileron. The design uses two sets
of contracting FMC actuators operating independently to actuate the deformable aileron in both trailing edge up
and down cases while matching coefficient of lift values of a conventional aileron. The design was optimized by
developing a series of response models which were then used to understand the sensitivity to material, geometric
and loading design variables while minimizing required force from the FMC actuators. Using a combination of
response models and sequential quadratic programming algorithm, a design is chosen that matched the
conventional ailerons performance at multiple flight conditions.
