A Nonlinear Modal Aeroservoelastic Analysis Framework for Flexible Aircraft
We present a nonlinear formulation in modal coordinates of the equations of motion of a flexible aircraft. It relies on the projection of the intrinsic equations of geometrically-nonlinear composite beams on the linear normal modes at a reference condition, which are coupled with 2D unsteady aerodynamics. The resulting description is suitable for nonlinear dynamic analysis and control design, w...
متن کاملNonlinear Aeroelastic Modeling and Analysis of Fully Flexible Aircraft
This paper introduces an approach to effectively model the nonlinear aeroelastic behavior of fully flexible aircraft. The study is conducted based on a nonlinear strainedbased finite element framework in which the developed low-order formulation captures the nonlinear (large) deflection behavior of the wings, and the unsteady subsonic aerodynamic forces acting on them. Instead of merely conside...
متن کاملFlexible Software Framework for Modal Synthesis
Modal synthesis is an important area of physical modeling whose exploration in the past has been held back by a large number of control parameters, the scarcity of generalpurpose design tools and the difficulty of obtaining the computational power required for real-time synthesis. This paper presents an overview of a flexible software framework facilitating the design and control of instruments...
متن کاملModal Matching for LPV Model Reduction of Aeroservoelastic Vehicles
A model order reduction method is proposed for models of aeroservoelastic vehicles in the linear parameter-varying (LPV) systems framework, based on state space interpolation of modal forms. The dynamic order of such models is usually too large for control synthesis and implementation since they combine rigid body dynamics, structural dynamics and unsteady aerodynamics. Thus, model order reduct...
متن کاملGeometrically Nonlinear Aeroelastic Scaling for Very Flexible Aircraft
High-aspect-ratio wings present in very flexible aircraft can undergo large deformations, which results in significant changes in natural frequencies as well as in static and dynamic aeroelastic response. This geometric nonlinear behavior becomes an integral part of any aeroelastic analysis to be conducted in such class of vehicles. Aeroelastic scaling is an important way to study the aeroelast...
