Aeroelastic Gust-Airfoil Interaction Numerical Studies
PI Vladimir Golubev
The project conducted in collaboration with WPAFB and Eglin AFB AFRL scientists over the past 8 years employs DOD HPC and ERAU computer facilities to conduct high-fidelity, low-Reynolds, aeroelastic gust-airfoil interaction studies to model unsteady responses and their control for small UAVs operating, e.g., in highly unsteady urban canyons.

Self-Sustained Flow-Acoustic Interactions in Airfoil Transitional Boundary Layers
PI Vladimir Golubev
CO-I Reda Mankbadi
This work carries out collaborative theoretical, experimental and numerical investigations of flow-acoustic resonant interactions in transitional airfoils which are responsible for sudden appearance of prominent acoustic tones and unsteady aerodynamic fluctuations in low-Reynolds-number airfoils.

Control Oriented Modeling of Aeroservoelastic Systems
PI Claudia Moreno
Modeling of a flexible aircraft requires a structural model coupled with a consistent aerodynamic model. A challenge of modeling aeroservoelastic effects is the sensitivity of structural and aerodynamic model parameters in the coupled system. As a result, extensive tuning is required to predict accurate flutter characteristics. This research program proposes to investigate the sensitivity of structural and aerodynamic parameters in aeroservoelastic systems.

Ab initio computation of gas radiation properties for re-entry flow simulations
PI Eric Perrell
CO-I Fanny Thomas
CO-I Spatika Iyengar
Renewed interest in planetary atmospheric entry, descent, and landing underscores the need for improved physics modeling in computational fluid dynamics. From a recent NASA solicitation, “the current state of the art for predicting aerothermal environments for planetary entry are dependent on physical models and underlying numerical methods that are, in many cases, two to five decades old.” Uncertainty in experimental data used in radiation heat transfer computations leads to, “over-engineering” of entry body heat shields, at a large weight and cost penalty. A method for computing gas emissivity and absorptivity from quantum mechanics principles is developed.

Aerodynamic Modeling of Ram-Air Parachutes
PI Mark Ricklick
CO-I Richard Anderson
CO-I Angelo Andres Fonseca Pazmino
CO-I Christian Alexis Guzman Zurita
The focus of this project is the investigation in flight performance of ram-air parachutes using Computational Fluid Dynamics (CFD). The modeling of a ram-air parachute presents challenges in the prediction of the in-flight geometry, as there is a strong interaction between the flow field and parachute structure. Methods were developed to approximate the geometry and efficiently model the parachute as a rigid body.
