Abstract

Investigations are conducted to mechanize a controlled spanwise-varying airfoil camber change for a high aspect ratio wing, resulting in optimized aerodynamic performance for a aircraft that changes weight by 50% over its mission. Mechanisms to achieve these shape changes are designed based on two separate design methodologies: a rigid body kinematics approach and a compliant mechanism approach.

A framework for optimizing mechanisms based on each approach is presented. Differences between the approaches are illustrated through the design of a mechanism for a specific set of airfoil shapes. Mechanisms are evaluated based on the error in the shapes and on the energy efficiency of the systems.
