Constraints Enforcement Using the Lagrange Multipliers Method for Aeriservoelastic Applications

The ever-increasing need for better performing, safer and environmentally friendly aircrafts, necessitates the continuous refinement of the predictive tools that are employed during the design and certification phases. The field of aeroservoelasti city, which encompasses airframe flexibility, control laws and aerodynamics, is of paramount importance in the design of modern aircrafts given their increased airframe flexibility and automation, and it is at the forefront of research interest by aircraft manufacturers.
This proposal aims to refine the aeroservoelastic analysis tools of Bombardier within the industry-accepted aeroelastic modelling environment of MSC. Nastran. The proposal will also explore the nonlinear predictive capabilities of MSC.Nastran in the presence of modelling nonlinearities at the joint interface between the control surface and the main surface. Furthermore, the aeroservoelastic response when utilizing electromechanical actuators in place of the conventional hydraulics ones will be obtained. The completion of the proposed research herein will set the stage for further research in nonlinear aeroservoelasticity for more electric aircrafts.
