Modeling and simulation of aircraft nose landing gear extension retraction system

With the deep integration of industry technology and information technology, computer modeling and simulation has been widely used in the development process of complex systems. That is, models are indispensable. They offer decision support and help tackle design projects. For the nose landing gear extension retraction system, this paper creates the mechanical structure model and hydraulic circuit model of the system. Based on the integrated model, this paper analyses the motion characteristics of key components, system extension and retraction time, etc. The model can realize rapid iteration of design changes, verify the rationality of the design in advance and achieve the purpose of saving development cycle and cost. In brief, it provides high-efficiency and low-cost support for the development of the landing gear.
