Wing Area and Aspect Ratio

This is the third post in a series of fundamental aircraft design articles which aim to give you an introduction to aircraft design principles. In the previous post we examined the lift, drag, and pitching moment coefficient acting on an aerodynamic body caused by the resulting pressure and shear distribution. In this post we introduce wing design and show why it is a great place to start when designing a new airplane.

The Drag Polar

Welcome to Part 9 in the Fundamentals of Aircraft Design series. In the previous posts we have covered the fundamentals of flight, studied the wing, fuselage and empennage, and have been introduced to aerodynamic lift, drag and moment coefficients. Now we put it all together and run through a preliminary drag estimation of a new aircraft design. Let’s get started!
