Aerodynamic Study of Different Types of Wingtip Devices

Abstract

The economic system of the 21^st century requires technological solutions that ensure economical and sustainable passenger and freight transport, also by air. To this end, aircraft manufacturers are constantly working to make their aircraft as economical as possible.
The aim of the research is to examine the effectiveness of the CFD simulation programs by conducting wind tunnel tests. This research also studies different types of wingtip devices then compares the results to determine the most effective one in terms of aerodynamical drag reduction. In the course of the research, we test wingtip devices of various designs in a self-built wind tunnel, and then compare the measured data with the results of the computer simulation.
