I got a B for my extended essay on Physics in 2020. The topic was “Re-evaluation of the validity of Equal Transit Theory based on empirical data and the specification of commercial aircraft”
[Table of contents]
During my participation in a physics summer course, I created a self-designed aircraft and utilized various theories and principles including the Equal Transit Theory in order to calculate the minimum and maximum specifications for the aircraft. The result of calculations based on the Equal Transit Theory seemed strangely large, which led me to reconsider the validity of the theory and its application. After more investigation revolving around the forces that act on a flying body, I found out that the theory was ruled incorrect on NASA education website and decided to further investigate this topic with a simple experiment. Therefore, this essay will focus on the following research question: “how valid is the Equal Transit Theory in comparison to calculations based on commercial aircraft specification and empirical data?” The relationship between the dimensions of the airfoil and the generated lift force was examined experimentally using a wind tunnel with the hypothesis that the calculated lift force will not equate with the theoretical value of the Equal Transit Theory. First, it is important to examine some key concepts regarding the subject of the essay…
