A bifurcation study to guide the design of a landing gear with a combined uplock/downlock mechanism [PDF]
Proc Math Phys Eng Sci, 2014 This paper discusses the insights that a bifurcation analysis can provide when designing mechanisms. A model, in the form of a set of coupled steady-state equations, can be derived to describe the mechanism.
