Analysis methods determining aerodynamic characteristics Project Details
| Abstract |
This research investigates and analyzes various methodologies for accurately determining the maximum lift coefficient and critical angle of attack of subsonic airfoils. The primary objective is to refine an empirical-analytical method specifically developed for calculating the aerodynamic characteristics of isolated wings in subsonic aircraft. Establishing these critical aerodynamic parameters is a fundamental aspect of the aircraft design process, as they directly dictate the permissible operational angle-of-attack range and significantly impact aircraft maneuverability. The study involved comprehensive computational analysis of the aerodynamic characteristics for a selection of NACA series airfoils, encompassing diverse thicknesses and cambers, as well as the NASA GA(W)-1 airfoil. Calculations were performed across a range of Reynolds numbers
using advanced computational aerodynamics methods. These methods included specialized programs leveraging the panel method, integrated with an integral boundary-layer model to account for viscous-inviscid interaction, and commercial CFD software packages that implement solutions to the Reynolds-averaged Navier–Stokes equations utilizing differential turbulence models. The strategic adoption of these computational approaches is anticipated to substantially decrease the volume and cost associated with experimental testing during aircraft design and development. Furthermore, a rigorous grid convergence study was executed during the numerical simulation of flow over the subsonic airfoils to validate the selection of computational grids, thereby ensuring the stability and accuracy of the results.
