The downward trim force comes about as a result of the need to balance the moment generated by the lift vector acting away from the center of gravity of the vehicle.

Thus during straight and level flight, the wing provides an upward lifting force equal to the weight of the aircraft plus the trim force generated at the horizontal tail to keep the aircraft balanced. Loads acting on a WingДЄ wing is primarily designed to counteract the weight force produced by the aircraft as a consequence of its mass (the first post in this series deals with the fundamental forces acting on the aircraft). In short, we have laid the groundwork to develop a conceptual design of a wing.Д«efore moving away from the wing weвЂ™ll now spend some time introducing the structural design elements that allow the wing to operate safely through all phases of the design envelope. We examined wing area and aspect ratio, introduced sweep and drag divergence and looked in more detail how the airfoil profile determines the flying characteristics of the aircraft. The last three posts in this series have focused on the conceptual design of the wing. 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.

In part 5 we looked at the role that the airfoil profile plays in determining the flying characteristics associated with its selection. Welcome to part 6 of a series on an Introduction to Aircraft Design.
