Abstract
This work describes the investigation of the aerodynamics characteristics of a canard type airplane by using Computational Fluid Dynamic (CFD). Each step of CFD such as improving mesh, domain size, turbulence models such as (Spalart-Allmaras and k-ω (SST)), and wall treatment was developed and chosen to best perform the simulations at different flight conditions of the aircraft. The goals of this study were to certify whether CFD can be a reasonable cost effective tool to be used by small enterprises that want to improve their designs. The different flight conditions tested were: takeoff, cruise, landing, and pre-stall. The Reynolds Number for each condition was approximately: 12.2 × 106, 21. 2 × 106, 10.82 × 106 and 16.22 × 106, respectively. After a close analysis of the results, it was verified that only lifting characteristics could be predicted with a reasonable error margin and, for that reason, material tests should be performed with wind tunnels in order to determine the drag aspects from the aircraft. Despite of this fact the results could be used as trends to better improve the design and tailor how the lift behave in each different configuration before wind tunnel testing.
