Linearized FUN3D for Rapid Aeroelastic and Aeroservoelastic Design and Analysis

Completed Technology Project

Project Description

Linearized FUN3D for Rapid Aeroelastic and Aeroservoelastic Design and Analysis
In Phase I, a prototypical FUN3D-based ZONA Euler Unsteady Solver (FunZEUS) was developed to generate the Generalized Aerodynamic Forces (GAFs) due to structural modes, control surface kinematic modes, and gust excitation using a frequency-domain linearized unstructured Euler solver based on the Navier-Stokes solution of FUN3D as the steady background flow. These GAFs can lead to a state-space equation representing the plant model for rapid aeroelastic and aeroservoelastic (ASE) design and analysis. The overall technical objective of Phase II is to develop and validate a production-ready FunZEUS that will be developed by enhancing the prototypical FunZEUS (1) to drastically improve its computational efficiency; (2) to expand its commercialization potential by interfacing with other commercial CFD codes; (3) to include the static aeroelastic effects in the GAF generation; (4) to demonstrate its applicability to complex configurations; (5) to showcase its plant model generation capability using spoilers and other control surfaces; and (6) to improve its maintainability and modularity by integrating all modules in a ZONA's database and dynamic memory management system.
