Design and Dynamic Modelling of a Fuselage-Mounted Main Landing Gear for a PrandtlPlane Civil Transport Aircraft

The subject of the present thesis is the design of the main landing gear of an innovative aircraft in the framework of the PARSIFAL project. The aim is the definition of a landing gear configuration satisfying all specific requirements of a future PrandtlPlane civil transport aircraft, including the introduction of electromechanical actuation. The design methodology adopted makes use of dynamic modelling and multibody simulation from the very first stages, with the aim of providing efficient and reliable tools for a preliminary sizing, and early evaluation of performances and dynamic loads. Simulations are carried out by integrating a commercial multibody code and specifically developed dynamic models of aircraft and systems. The results obtained will allow to easily adapt the landing gear to the final configurations and weights of the aircraft. In addition, the models and tools developed in this work can be used for the evaluation of ground loads to be considered in the airframe structural design, and for takeoff and landing simulations when designing the flight control system
