GTC-300 CFD Data

OVERVIEW

Contained herein are the data and results of the Computational Fluid Dynamics (CFD) analysis that was conducted on the a 3D model of the GTC-300 airfoil. This data illustrates how the airfoil performs in free-stream air flow by comparing Downforce vs. Angle-of-Attack (AOA) vs. Speed, and Drag vs. AOA vs. Speed. This data will provide insight with regards to how the airfoil performs with respect to these conditions. Additionally, the analysis contained herein will provide insight with regards to how to apply this data to real world applications.

DEFINITIONS

Typically, the AOA is defined as the difference in angle between the chord line and the vector that represents the undisturbed free-stream air flow, where the chord line is the line that passes from the leading edge to the trailing edge of the center section of the airfoil. For the CFD simulations conducted on the GTC-series airfoils, the center cross-section of the reference plane (or "center reference line") is used in place of the "chord line." Therefore, the AOA is defined herein as the difference in angle between the center cross-section of the reference plane (shown in the image below) and the vector that represents the relative motion of the undisturbed free-stream air flow. A ruler that is placed on top of the center section of the GTC-series airfoil would be the real-life equivalent of this reference line.
