Welcome to part three in a five-part series on airframe structures and control surfaces. This tutorial focuses on the structural design of the wing and introduces the control surfaces attached to the wing’s trailing edge.

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.
Continue reading “Wing Area and Aspect Ratio”
Aspect ratio is a measure of the ratio between the span of the wing to its chord. In most cases the wing chord is not equal along the length of the span which is why aspect ratio is most commonly calculated by dividing the square of the wing span by the reference wing area.

The reference wing area is defined as the plan area of an aircraft’s wing (usually including the area of the wing through the fuselage).

The Wing Plot Tool allows you to sketch a wing planform by defining a valid combination of the critical wing geometric properties: Wing Area, Wing Span, Aspect Ratio, Taper Ratio, Root Chord, Tip Chord, and Sweep angle (quarter chord).
Use the sliders below to select or deselect geometric variables.
