Preliminary Estimation Methods for the Definition of the Landing Gear

The landing gear of an aircraftis an important part of the aircraftstructure. The landing and the taking offare most critical parts of a flight mission. The main goal of this paper is to provide a methodology for designing and sizing the landing gear taking into account its main three functions: to ensure the taxiing during the take-offand to ensure both the dynamic contact with the ground during landing and the taxiing required until the aircraftloses speed. This paper continues our concerns about different aspects of the complex landing phenomena. The landing gear is the component that will likely cause many problems in the aircraftdesign. Its design combines the best in mechanical, structural and hydraulic design. The designed landing gear should be able to meet the specifications and requirements imposed for example by CS23.
