Abstract:

This technical report presents some preliminary work toward a project that seeks to develop a shape memory alloy actuator for rotor and stator blades in aircraft turbine engines that will increase efficiency and extend flight ranges. A major step toward the projects completion is the development of a model that simulates both the fluid-structure interaction in the engine and the mechanical behavior of the shape memory alloy actuator. A simple computational fluid dynamic CFD case with 2 pairs of actuated blades is presented as a proof-of-concept. Immediate future work will involve altering the case setups for CFD simulation to more accurately represent the fluid-structure interaction in a real engine with articulating turbine blades.
