The Effect of Wing Configuration on Pressure

Overview

Objectives/Goals This project was an investigation of how different wing configurations affect the pressure measured on aircraft. Methods/Materials Using an engineering application called SimScale that performs computational fluid dynamics (CFD), I set up wind tunnel simulations for three wing configurations; straight, swept, and forward swept. I kept the same fuselage with the different wings attached. Each configuration was subjected to 80 m/s winds. Results The swept wing, as predicted, did have the least pressure, but unexpectedly the forward swept wing had the most. The average pressures on the combined wing and fuselage were: 134 psi for the straight wing, -69 psi for the swept wing, and 494 psi for the forward swept wing. Conclusions/Discussion This investigation contributes to science it because provides measurements of different wing configurations. Knowing exactly how much a wing changes flight characteristics can be important for aerospace engineering and maximizing the efficiency of an aircraft, and my project makes contributions towards this.
