Aerodynamic Lift, Drag and Moment Coefficients

In the previous post we introduced the four fundamental forces acting on an aircraft during flight: Lift, Drag, Thrust and Weight and examined how they interact with one-another. We are now going to look more closely at the two aerodynamic forces Lift and Drag. We will look at the relationship between the two forces, study how they interact with one another, and learn how to non-dimensionalize the resulting forces. Let’s do this!

Horizontal and Vertical Tail Design

This is part 8 in the Fundamentals of Aircraft Design series. In the previous posts we’ve looked at both the wing and fuselage in some detail. Now we move onto the aircraft tail section and examine the function of both the horizontal and vertical tail. We’ll then introduce an empirical method to size both surfaces on a new aircraft design.
