Development of an Actuation System Mechanism for Extension and Retraction of Flight Control Surface by Utilization of a Shape Memory Polymer
The following paper presents an idea of implementation of an actuation system for the extension and retraction of
flaps in aircraft control surfaces, made up of shape memory polymer material having the intrinsic property of shape recovery
upon application of heat. Shape memory polymers are a type of macro-molecular smart material that can respond to external
stimulus with change in macroscopic properties and can recover its original shape upon heating. SMPC (Shape Memory
Polymer) materials have the ability to undergo deformation which can later be recovered to transform back into its original
shape. The intrinsic property of shape memory polymers of changing their shape as a function of temperature can be utilized
for deflection of the flight control surfaces during flight.
