Geometric nonlinearities of aircraft systems
B. Krauskopf (University of Bristol, UK) and P. Thota (Department of Engineering Mathematics, University of Bristol)
Geometric effects, typically via angular variables that are not small, are important for aircraft operation because they result in nonlinearities that influence the dynamics of the subsystem under consideration. Geometric nonlinearities are particularly pronounced in aircraft ground operations. As concrete examples we will discuss the geometry of an aircraft while turning and the influence of a non-zero rake angle of a nose landing gear.
