XFOIL Tutorial 5: Polar Plot Basics (Cl vs alpha Cl vs Cd Cm vs alpha Cl vs xt/c)

Follow
the Science of Flight

This video goes over the basics of creating polar plots using XFOIL. It also quickly reviews the lift polar (coefficient of lift vs angle of attack), drag polar (coefficient of lift vs coefficient of drag), moment polar (moment coefficient vs angle of attack), and transition plots (coefficient of lift vs chord normalized transition point). Polar plots allow us to analyze the performance of airfoils in terms of lift, drag, moment, etc..

Series Description:
This is another video in a new series on the XFOIL software brought to you by the Science of Flight, a new brand on YouTube. Whether you’re an undergrad in an aero course or a working professional that just got placed into an aero role, this series is for you. Although the idea is to create an awesome lecture series to support aerospace engineering education, the hope is that this won’t just be a lecture series but when it is combined with other interactive content it can become an entire learning system to truly master XFOIL. If you have good ideas for apps, interactive virtual models, software, or even learning objects that could be 3D printed throw it in the comments below along with what topics you want to see covered. After you comment, check out the next video in the series.

Channel Description:
Since the beginning, man had looked to the sky only to have remained earthshackled. Aerospace engineering changed all that in a very short 100+ years. The airplane has come a long way since the 1903 Wright Flyer and aerospace engineering along with it. If you look at a modernday fighter jet it’s no wonder that nowadays aerospace engineering curriculum can be a daunting task. This leads to 19 credit hour semesters being the norm, fast pace classes, missed content, less interactive lessons, lower comprehension due to shorter discussions, and never enough time to read the textbooks. Combine this with thick accents, difficult concepts, and professors who care more about research than teaching and engineering education turns into a game of stamina instead of a game of wit. At the Science of Flight it is believed that excellence in engineering starts with excellent education and tSoF is dedicated to improving aerospace engineering education for the student as well as the working professional.
