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!

Introduction to Wing Structural Design

Welcome to part 6 of a series on an Introduction to Aircraft Design. In part 5 we looked at the role that the airfoil profile plays in determining the flying characteristics associated with its selection. In our final introductory post on the wing we look at a typical wing structure, the various loads that the wing is expected to carry during operation, and introduce the methodology behind designing a semi-monocoque wing structure.

Fuselage Sizing and Design

This is part 7 of a series on the Fundamentals of Aircraft Design. In part 6 we looked at the structural make-up of the wing. In this post, we move away from the wing and introduce the aircraft fuselage: we’ll look at the various ways to construct a fuselage, how to size it correctly, and introduce the various loads that the fuselage structure is expected to carry during operation.
