Design Process: Wing Design

At this point in the design process, we have gotten the airplane sized, balanced, and after six months of consideration gotten the landing gear...

Design Process: Landing Gear, Part 6

Last month, I ran out of space before getting to the end of our discussion of landing gear. This month, we conclude the series...

Design Process: Landing Gear, Part 5

For the past few editions of Wind Tunnel, we’ve been exploring the factors that drive the configuration and placement of landing gear. Last month we took a look at the factors affecting the directional stability and lateral stability of the airplane when it is rolling on the ground. This month we switch axes to look […]

Design Process: Landing Gear, Part 4

Last month we looked at how the static stability of the airplane when it is sitting at rest on its landing gear affects the position of the landing gear legs. Once the airplane is in motion, there are additional considerations that come into play. We will now turn our attention to how dynamic effects dictate […]

Design Process: Landing Gear, Part 3

Last month we took a look at the basic characteristics of the two most common landing gear configurations: tricycle and taildragger. We will now turn our attention to some critical factors in the proper integration of the gear into the overall airplane configuration. The configuration of the landing gear and its placement affect the static, […]

As we started to discuss last month, the landing gear is a major component of the airplane that affects the design in significant ways. Delaying the layout and design of the gear until late in the design process will inevitably lead to problems. Accordingly, the designer should address the major factors associated with landing gear […]
