Aerodynamic analysis and optimization of Low-speed wings Report By

Abstract

The aviation industry has been constantly developing new and powerful aircraft. Since the recent improvement of more powerful engines as well as enhancement in the aerodynamic properties flight speed has been faster day by day. Especially, an introduction of jet engines and sweptback wings has made it feasible to achieve more speed than that of sound to the aircraft. The flow phenomena will occur depending significantly on this sonic speed, which is the rate at which very minor atmospheric pressure perturbations spread. All flow velocities around the aircraft are considerably slower than the speed of sound when travelling at low speeds.[1] The study primarily discusses the choice, design, and FEM (Finite Method Analysis) of low- speed aircraft. The introduction of the aircraft and its brief history is covered in the first portion of the report. This is followed by a background section outlining the report's correct goal and objective. Similarly, to that, it gives the reader a solid basis so they can comprehend the goal of the entire investigation. The result of Ansys' analysis is presented in the second section of the report. The model is similarly sent through the programme before receiving specific boundary conditions, which allow for the right set and solution to be provided. Similar testing is conducted on the model in the De Montfort University lab's wind tunnel. Finally, the study compares and discusses the findings of both the software and wind tunnel tests.
