Numerical Continuation Analysis of a Dual-sidestay Main Landing Gear Mechanism [PDF]
AIAA Atmospheric Flight Mechanics Conference, 2012 A model of a three-dimensional dual-sidestay landing gear mechanism is presented and employed in an investigation of the sensitivity of the downlocking mechanism to attachment point deflections. A motivation for this study is the desire to understand the underlying nonlinear behavior, which may prevent a dual-sidestay landing gear from downlocking ...

Weak links design for the main landing gear leg mount
Engineering Journal: Science and Innovation, 2023 The paper presents an overview of the main strength requirements to the typical civil aircraft landing gear design. Elements of the main landing gear leg mount on the airframe were considered in more detail. In the mount points, shear bolts called the ”weak links” are usually installed in order to prevent transferring the dangerous loads during rough ...
