The subject of the present paper is the design of an innovative fuselage mounted main landing gear, developed for a PrandtlPlane architecture civil transport aircraft with a capacity of about 300 passengers. The paper presents the conceptual design and a preliminary sizing of landing gear structural components and actuation systems, in order to get an estimation of weight and of the required stowage. The adopted design methodology makes use of dynamic modelling and multibody simulation from the very first design stages, with the aim of providing efficient and flexible tools for a preliminary evaluation of performances, as well as enabling to easily update and adapt the design to further modifications. To develop the activity, the multibody dynamics of the landing gear (modelled using Simpack software) has been integrated via co-simulation with dynamic models developed in the Matlab/Simulink environment.
